It can sometimes seem like we aren't doing anything if you don't hear from us for a while so I thought I would do an update of where we were just for info
Thank you so much for sharing! You are truly a teacher, which I feel is the greatest compliment one can receive. You've inspired me as well as countless others to actually put their ideas into action.
Wow this is my mentor I'm obsessed with how clean output of information making it very followable.I would be a gift if I could work under him I would do anything for that opportunity.could that be entertained.this man should have millions of viewers hes breaking down very very important matters that should be shared for evolution. Thank you brother for everything you do will God light your path.
5kwh would be fantastic for that size. A conventional deep cycle battery of even greater volume for home energy storage might have a "usable" storage of 1200wh at 1/2 of full (2400wh), which is calculated from 400Ah @ 6V. If these batteries that you are making can be drained and filled without serious degradation then this is absolutely revolutionary. Am I missing something?
These videos have become a source of primary entertainment for me - much better than watching telly! Apart from the delight ofwatching a knowledgeable and creative enthusiast at work, I'm really excited to see what you guys are going to do to the whole energy market. Keep going guys - I truly hope you make a fortune into the bargain :-)
Amazing videos Robert. Your enthusiasm and ability to bring the battery subject alive is tremendous. For a number of years I had a business in the renewables sector and storage is by far the biggest need. My thoughts are that whilst efficiency is always a good thing to chase, the winners will quite simply be those with the lowest cost per kWhr and simple non-toxic components. Refinements will come with production experience. Please keep up the good work. Richard
This all looks so much fun, I've gotta get playing with this stuff myself!!! 5kWh in a standard car battery size... that's getting serious. Keep up the good work Rob!
I check for your videos everyday and get super excited when there's a new one. your journey is exciting and enlightening. looking forward to the big battery!
Just always a delight to hear the progress which you achieve at an astounding pace compared to the established commercial guys. Caught that comment on Toll Processing, great idea..... All the best Mate.....
I stumbled upon your videos and I am amazed at what you are coming up with. Please keep up the great work. You are extremely enlightening and a great educator. Many Thanks.
Blooming marvellous Rob! This is exactly (pretty near) what I want to make for my home made Solar & Wind, firewood drier. It's a one off kiln (greenhouse) using sun and wind to dry my firewood. We need all the help we can get here in Argyll - the wettest place in the UK.
From a product design perspective, interlocking boxes that can be arranged in multiple directions seems like a good approach to adapt to different applications / retrofits.
Holy Hell Robert! Every limitation to EESD's that i have encountered, is completely undone by 1 (or 12) of your videos! lol is it murray or merlin? either way your videos are magic to me. please keep them coming. I'll watch it even if your just sitting there, drinking tea/Beer, rambling about politics of elemental resources, or theory of nanostructure potentials, anything mate! Ill never get enough :)
You and your team are awesome my very good friend. That is fantastic news. I am looking forward to the car battery results when they come through. Keep going my friends. Have an amazing weekend. My best regards to you all.
Hi Rob, Great video, If you can get 5kwh/12v/10klg in a reliable battery you will be holidaying on a beautiful desert island that you will own and the yacht that got you there. And i hope you do. But why copy the shape of a car battery and having to connect all the separate sheets. Using a4 fan feed paper and a few rollers a bath of ink and some stepper motors you could produce miles of the stuff automatically. A similar system could then be used to produce 2v 9" high round battery's in minutes with the capacity obviously dependent on diameter. Not quite as efficient on space than a square battery but cheaper and easier to make, and to a point irrelevant for solar storage. Keep up the good work. John
there are lots of reasons to copy an SLI shape mate - but basically we make a decision and go with that - often it doesn't really matter - sometimes you are right an sometimes you are wrong - but one thing i have noticed is that it doesn't matter what you decide someone somewhere thinks there is a different way - and they are right lol
Always interesting to have an update! Hope you had a good holiday. Personally I would really like a better alternative to 18650's, in the same form, to fit into existing projects, but I understand where your at. Good luck.
Thank you ............ when u have one together , you can run the check again & see how those figures hold up in this configuration , please . Interested to know if there is heat dissipation problems .
Their flexibility would allow being rolled up and put in 90 or 100mm PVC pipe which is cheap and so are the end caps. If you could get large sheets (say 1mtr sheets) made of sufficient length to roll fit/fill a 1mtr length of PVC pipe you would be able to create high capacity tube cells that could be connected as batteries for different applications. Even drill holes in the garden with an orger and place them underground
Seems like overkill to stuff your robust & flexible carbon batteries into Group 27 packaging (designed to protect *brittle* lead-acid batteries). It's like giving superman a bulletproof vest :D. I'd have expected you to put them into sealable film bags, like prismatic lipos. But i guess in an experimental car environment you never know what sortof dings & bingles you're gonna have eh? When you're a test-pilot shooting for the stars, always wear your helmet hehe. Btw, it's always lovely to see what you're getting excited about Rob.
Sometimes after watching a vid i have to go and make myself a beverage and wander around the house absorbing what ive just seen, i do this subconsciously, its due to excitement.......Just had one of those moments......thanks for sharing....phil
Awesome update Sir RMS - thank you! And thanks again for all the work you put into making these videos and making them public. I've had "ideas" floating around in my head for years, and your videos have inspired me to finally start taking "action." So I don't feel you have any reason to apologize to not putting out videos more frequently. You've already done a great service for others (look at all the other video channels from people you've inspired), and you've said repeatedly "this is a hobby for you." :)
Thanks and will do.Video(s) likely first of the New Year as I'm a software developer by day, and a wanna-be mad scientist only by night ;) But so far I have already collected my hydrochloric, sulfuric and phosporic acids, KOH, acetone, GO solution, 5micron graphite bucket, activated charcoal and povidone. I also acquired some Celgard (just for consistent separator results), and PVAlc powder. I messed up and ordered the wrong grafoil and instead got more of a graphite plate - bleh. But I have copper and nickle foils "in the post" as well as a variable PS. I'm hoping to duplicate your results on the various super-caps and try numerous iterations of active materials and electrolytes/ionic liquids After that a hydrothermic reactor will be in the works to take a shot at hemp, and also graphene quantum dots (in a DSSC?) Then I'd like to play with doping graphite/carbon as electrodes in water electrolysis and fuel cells. Anyway, thanks for the inspiration!
If you have a Harbor Freight around they sell a plastic ammo can with a lid that clamps on. I'm not sure how water proof the seal is and it does have individual cells in it but they are a good start to begin with.
Just wanted to say I thoroughly enjoy watching these videos! The content is amazing mate. Wish I could be apart of the experimenting process. Best regards and keep em comin!
OMG I am actually beginning to understand the process, this tech is the most amazing world changing science for the preservation of the earth , my thanx to you Robert and co.
Entirely inspirational Mr Murray-Smith, great work! Will attempt hydrothermal carbonisation starting from unwoven hemp yarn in shortest time possible. As first approximation, initial attempts will be using microwave oven, similar to what you spoke of in one of your previous videos. I do plan to try and activate it before use, but we'll see how it goes...Thank you for great content!
Hi Robert. Another very interesting video! I've been watching for quite awhile now and haven't seen much info concerning heat in the charging and discharging of your batteries. Do the graphene and hemp experiments generate much heat during both those phases? Thanks so much for taking the time to keep us informed on your experiments! Hasta, markos
Thanks for another video. So exciting to see your developments so far and where it is going. Can't wait to see how the car battery goes. I'll have the a batch when they come to market. EV conversion here we come.
I very much appreciate your videos Robert and grateful you are so open with information. You frequently refer to your active material. Can you say what it is or point to a video that reveals it please?
i have done loads on different active materials mate - with videos dedicated to various types the material you choose is really up to you - you can use one of mine or come up with your won - that's why i just refer to it as the active material
This is great stuff. I desperately want the know-how to do this sort of thing. These vids are best source for that knowledge as far as I know. Still a steep learning curve for me though! Are your battery plates paper based or are they entirely ink and binder etc?
Adrian Atkins how about some write ups summarizing the process from start to finish. Plus where to get materials. A technical blog companion to the vids would be nice
Somewhere Sane to discuss this stuff would be good. utoob comments tend to be utter crap. I'll give the whole process a try on the sciencemadness forum, once i track down all the videos in sequence.
I'm someone who wants to see 18650s but the performance is so good, might as well just tape some coin cells together in a roll, be perfectly good. Far better to concentrate on something that will more difference to more people faster and in a more serious way. Awesome work as usual :)
One thing that caught my eye is that you aren't using a hemp based binder. Seeing as how a hemp based active material is superior to graphene or lithium it would stand to reason that a hemp based binder in a hemp battery would be superior to most other binders. Am I off base on my assumption?
I'm your avid follower😊😊 if may I ask, Which battery is the cheapest to make? Which one has the highest capacity of all the batteries you have made? I'm planning to build an off grid battery..😅
Flexible battery materials would be the ideal format for an e-bike. The rider could then wear the lighter battery/controller inside a haversack rather than the usual ugly appendage to the bike frame. There would be the added security benefit, as the rider dismounts the battery stays separate from the locked bike. A4 sized units < 5kgs would be very desirable : )
Hello Robert, I watch your videos for years, your work is simply fascinating! But there are some important issues that I can not find in your videos. 1. Do you use a water-based electrolyte or an ionic liquid? 2. an electrode is based on hemp, what is the second electrode made of? 3. Is the separator a diaphragm (only electron-permeable) or is it made of paper, ( is it permeable to ions)? I think many people would be interested in this. So far I have carbonated hemp rope (about 10 ohms per centimeter in the lump.) Now I want to start trying to build a comparable cell. gruß Alex
Hello, I have found the answer to my second question. I feel so stupid !! Had probably a black out, or translation error. Lead me lol Lead !!! (-: gruß Alex
I love your can do approach. Couple of question - would not the electrolyte cause the internal batteries to (eventually) split apart and how do you plan to connect up the cells, or are you going to remove the separators and just have a number of cells (layers) in parallel (to make up the 12v) and a long length of material to get the energy denisty.
Dr. Shamus: Perhaps this flexibile battery material could also be sound dampening material. Cover the ceiling & walls to dampen the sound & store energy :D
Do you need the paper? I am wondering if you could not just spin the paste mix and make a really thin sheet (foil) like they do with the super high end electrical steel.
You're videos are always entertaining, cutting edge stuff, I came across you when I was doing some copper plating last year, you're obviously a Northerner, can't quite place the accent, where are you? I'm not after the exact address just the town, need any assistants?
fantastic Robert, always good to see the universe delivering the really good ideas to someone with the intelligence to know what to do with them.. thank you for sharing your progress and discovery. I've know doubt you could have sold your skills to a corporation and been 10x the richer, but we would never have known the secrets science still holds.. good luck, can't wait to see the results 🙄
I'm intrigued by the idea of a single cell as an EV battery. Layers of large sheets with the "can" of the battery acting as top and bottom current collectors, like a giant rectangular button cell. The weight and cost savings over thousands of individual cells might be something...
sure - but their might be other issues from the scale - like raised ESR, lack of control, insufficient redundancy that sort of thing - but interesting idea mate
Hi Robert,I am curious as to the resistance of your new active material +sbr+CNC . Is the resistivity in the single digit to sub ohm range? I realize that this probably isn't as pertinent as power metrics but I am attempting to get a better grasp of the impact of ESR on power storage/generation device efficiency in a system.I experimented with natural and synthetic (specifically SBR) rubbers with activated charcoal as well as homemade PVP coated graphene.The best sheet resistance I was able to achieve with activated charcoal and SBR was 60ohms/cm2. 600ohms/cm2 with homemade PvP graphene.
This is fantastic. Fabulous. Amazing. Finally new batteries after 20 years of 'nothing new here guys'. I hope this will be open source with you as the hero of mankind. Or are you gonna patent it? Because then it can be stolen and lost. Thank you.
You have so many videos of you making active materials.Which particular one are you using for this battery and whats the video tittle of you making it?I am new to your chanel so i am a bit lost navigating true it .
Too bad since the battery you are making seems in 400-500wh/kg range witch is crazy high and has this intresting no collector thing going on.So i was curious which strategy gave this much promice since it seems most of the active materials you show dont come close.
Dear Robert, thanks for the post. I have been following with fascination. Now that you are rid of the current collector, what resistance are you getting across your cells? Thanks in advance of your response.
pretty low mate - i have measured the bulk resistivity of the material and noted the reduction of voltage drop but i have yet to measure the resistance across the cell
If you listen to this stuff this morning on Dr & hospitals ...... working to hard to have time to get teaching on new techniques ..... all the same problems . Always have problems with the " can you just " & " it won't take long will it " ................
Generally delivered by those who have never done the job ..... or know how its done . And often get 'issy if asked for more money / time to get the job done .
I might be able to get into the garage in the next few weeks mate and give some of that a go. Iv got a few theory's that I want to try out I'll let you know if I get any different results
Hello Robert, A question please: Does your graphite battery work at very low temperatures? So at about -40 to -50 degrees Celsius? Best wishes from germany....
Fantastic! I'll have to buy one from you for my truck. By the way, I ended up putting my projects on hold indefinitely while I move. So I ended up buying a battery from AutoZone. I think they would love to buy your battery ideas since lead is so hated here in California. Imagine if they didn't have to buy the battery core from me!. They keep the profits. And on top they can just offer a voluntary recycling program to get the plastic back. California gets rid of lead. I get a long lasting deep cycle battery. That's a win for everyone.
yeah to do a win for you besides a one time payment, you need to patent a key element so you can rent it to AutoZone. but really what I mean to say is that batteries would become as recyclable as normal trash. that's a win for everyone except the lead industry. I am sure we still need Lead for other stuff, but they would get shrunk, so the price of lead might raise. and that is a win for the environment. if people paid for the real cost of stuff, they would not buy. this burdens lead with competition.
Hi rob Grate that you are going straight to car battery. Are you also looking at the 18650 and small flat cell type as they are the most widely used cells in the word today. As you know I have been trying to make a dry electrolyte. I have made a past that is now working but i is very slow in charging and I don't know if it will dry up and stop working as of yet. Look forward to your video on building up the car battery and testing.
thankyou your truly inspire ...been playing... conductive pva electrode rolled out and then a quick rinse bath in medium sodium hydroxide solution , sets as fast as you can say (magic) , next ... can you say conductive carbon/graphite hot glue sticks (allows gluing of films for booking process) onto common rails, last .. carbonisation of hemp fantastic , chicken feathers , flax also good ... another big thankyou ...
Amen to no current collector. But if you don't need flex active material would you get better performance with no binder at all - only has to be stable enough to roll or fold into final package ???? In following and learning from your super cap videos, I've found that performance was greatly improved if I completely eliminated the 5% Acetone/ABS binder I was using in plain old powdered up Activated Carbon. Like a 10X improvement. The activated carbon 'stuck' well enough to the NaCl wetted paper separator I was using. Lots of ways to deposit it to the paper - I just sprinkled it and pressed. Cheers and charge on.
What is making these batteries so effective and able to charge just by clipping the active material? Is it the homemade paste? Is that why its so flexible and strong too?
I have two questions, Doc... that bullet-proof thing you made. Will you open that tecnology too? Would be great to start creating a whole plastic car like the fiber-glass replica we found around. Other is that plastic that responds to laser beams. Will you open that as well? I can see great lighting signatures in the vehicle too =)
I am making your hemp carbon batteries Ribert, however, I suspect that my mixture of EITHER CMC Solvite or the RBS 3095 carpet adhesive is not pure enough because I am having bad voltage leakage. What are your thoughts on that? And, why the use of a hydrothermic carbonizer if carbon is what you want,.. Couldn't you just burn some plant matter and get the same product? Please do more updates..I love them!! :)
Sir I really appreciate your response, is this video I need to see to understand building your structure battery,how you made the flexible plate and the piling and connection of the plates
You mentioned that the finished sheet was conductive. How many ohms of resistance are there across the face of the finished sheet? If your probes were one inch apart, what would the ohm reading be?
Every time I watch one of your videos I get inspired to try something out. And then you go and make something better before I get a chance to replicate. I'm still exfoliating my graphite in a cheap jewelry cleaner. What happened to your printing press?are you still going to try to print a battery?
Why you don't work on "binder free" electrodes? For example by ED on conductive textiles (electroless nickel deposition on PET) you can grow active materials on flexible conductive substrates without binders... high surface area, more active sites. Your followers could also learn the electroless plating science.
Hi, Robert thanks for the update! What is the definition of the term Caland? that you said at 1.58 or so? is it just mixing the materials or is it a heat treatment of some kind?
Now if only you could teach us how to make a rolling mill to make these sheets. First thing I'd do is get some of those big HDPE tubs and make huge bucket cells that need a forklift to move.
