We know from previous episodes that the National Grid could easily handle every car in the UK being switched to electric propulsion. However, are there enough raw materials to build lithium-ion batteries every car in the UK, or the world for that matter? We start off by looking at what goes into a lithium-ion cell, and then look at global reserves of the most contentious raw materials.

Very comprehensive supported with excellent diagrams

Brilliantly explained as always. It’s about time the Luddites got their facts right regarding the use of lithium and cobalt.

Great video and very informative.

Use of rare earth elements is always thrown around as a reason why batteries are bad. I never actually knew the answer. Fantastic content 😎👍

Basically, once they're in the system, they *stay* in the system.

I'll need to watch it again, but I think I grasped most of this one! Thanks Euan 👍

Subscribed some time ago on a hunch that this channel might provide straightforward information. Glad I did. That was straight to the point.

Very informative, and you wisely stayed away from the political "Risk Game" aspects of primary materials. Living in Switzerland, there are many groups trying to have these companies become better citizens, and they are fighting as if their profits depend on it. I have proposed Windyday Concept, since we really should take advantage of this lockdown and financial crisis for the people to do what is an advantage for them. And that is building the batteries, solar panels, wind & tide turbines locally and then using the sun, wind & tides to power their world and telling the Banksters "Adios". Of course, there is much resistance from the oil lobby, and now public opinion has been swayed by Michael Moore's Mockumentary.

Excellent presentation of information that so many people get wrong ! Spot on !

I just found your videos. These are awesome thank you. Oddly I have heard of you through a few channels (energy saving trust guy etc) but didn’t realise you had a RU-vid channel until transport evolved recommended you. You should do an appearance on a bigger channel like HyperChange our now you know and get your numbers up 😊 any thanks for the awesome content.

I always knew Anode to be +ve and Cathode -ve, I didn't realise this is reversed in Galvanic vs Electrolytic.. every days a school day. Great Videos Euan. #mythbuster

I have a question, first i should say i’m a physics high school teacher and in the past chem teacher, but nowhere near your expertise. But early on in the video you talk about the polymer membrane only allowing Li ions through, but not electrons, is this due to the electrical charge direction rather than the size, as electrons are a lot smaller than any ions of lithium? I assume it’s because the electrons are attracted to the Cathode and ions conversely???? Can you explain?

The separator in a Li-ion cell has tiny pores that are wide enough to allow lithium ions to travel through the separator to the cathode on discharge, or the anode on charge. This also requires the electrolyte to be ionically conductive by having a lithium salt in it. However, the separator and electrolyte in a Li-ion cell are not electrically conductive (much like why plastic is used to insulate electrical cables), so electric current cannot flow through them like they can the metal that makes up the wires in the external circuit. So it's nothing to do with the size of electrons vs lithium ions and everything to do with ionic vs electrical conductivity of materials. Also, on discharge, an electron is stripped from a lithium atom in the anode and both travel to the cathode, the Li+ ion via the separator and electrolyte, and the electron via the external circuit. An electron then recombines with a Li+ ion in the cathode to form a lithium atom. The opposite happens during charging. Therefore, electrons and Li+ ions are both attracted to the same electrode at any one point.
