The science inside lithium-ion batteries - with the Faraday Institution

How do Li-ion batteries store and release energy? Discover their inner workings from Professor Louis Piper - researcher at WMG, University of Warwick, and a Principal Investigator at the Faraday Institution.

The Faraday Institution is the UK’s independent institute for electrochemical energy storage research, skills development, market analysis, and early-stage commercialisation. Bringing together expertise from universities and industry, the Faraday Institution endeavours to make the UK the go-to place for the research and development of new electrical storage technologies for both the automotive and wider relevant sectors.

The best explanation of lithium batteries that I have ever seen. Thanks for the educational video!

[mdobr]

Fantastic presentation Mr. Piper. Thanks!

[jamesraymond]

Very clear. It would be helpful to distinguish between lithium batteries and lithium ion batteries.

[robinwhitebeam]

I like the length and format of the film, but I am now looking for a longer lecture covering the same material, is their one available from the RI I wonder?

[timothyroberts]

Was hoping to learn how/why they degrade over time. What the electrolyte chemical is and why there is a fire risk.

[inGuy]

it would be good to consider formats or designs that would make the materials recoverable and recyclable. Perhaps something like being able to unroll the layers the way film was unwound from cartridges so it can be processed....

I have some large 10-20ah 6s lithium polymer packs that have puffed into circles. What am I supposed to do with them? The local dump won't take them. And I can't find any recycling facilities that take these.

[MrEnglischjules]

interesting. I just added a new solar panel and one of those batteries to my camper. the video explained it in a way i understood

[knightsljx]

The explanation is incorrect. Maybe it's trying to dumb down for the audience, but during discharge, it is the Cobalt that is reduced from Co3+ to Co2+ and in the Li+ intercalates as LiCoO2. The Li does not recombine with the electrons, otherwise there would no voltage. This is a science channel, be precise

[bodilnielsen]

I would love to see a similar video just for Na batteries, which also includes advantages and disadvantages of Li vs. Na and the future prospects. As far as I know the supply of Li might become an issue in the future with the world wanting more and more batteries, so would be nice to learn something about the possible solutions to that :D

[monicalif]

Mark, I have some Timex watches to recommend too…when your Casio breaks😊

[rovert]

Good presentation. My real concern with batteries is the issue of safety. I'd trade some performance for a safe battery.

[QuantumLeapResearch]

Great video, simple explanation as it should be. I see Atomic batteries being the gateway for phasers in the medical field.

[roop]

Those sheets look like forbidden seaweed!

[johncarter]

Do a follow up on all aspects of recycling lithium and lithium-ion batteries and make it 12 minutes. Google search says only 5 % are recycled world-wide. Unacceptable!

[guyh]

So usable electrons actually are a byproduct of ions being moved?

[THESocialJusticeWarrior]

4:51 what the heck is that on her head? O.o

[ehfik]

"isnt it nice to watch some historic documentation?"

"Na- i on the future track."

[HenkBronkhorst-cc]

may i correct you you know about the chemistry only for that i give you my respect
but what do you know from electricity and use it

[charlesco]

So basically half the battery is empty. It's like a sandwich shame you can't make a big Mac with one extra empty bread in the middle?
