Charge cycles and energy density are relative to each other. If you have a battery that has 1/2 the energy density but 2x the charge cycles than this battery, then they're effectively going to last the same amount of time. So even though lithium iron phosphate batteries have a 3, 000 cycle life, because these are so much more dense, they really would only need to get up to maybe 1500 cycles to be in parity with them.

[grayukuk]

Remember, with the videos, it's quality, not quantity, that matters!!

[MrWilliam.Stewart]

Electrifying.
I was really amped to watch this.
You explained both the negatives and the positives, also you have a good chemistry with your audience.
The information flowed well, and you took charge of the situation.
You, Sir, are the ion man.

[jrb_sland]

I'm less interested in greater range than in mass decrease for the same storage capacity - the lighter the car, the less it will cost, generally speaking. These are still early days - the future is hard to predict, but we have lots of smart people working on these problems. Great time to be alive !

[waynethefridgemanosborne]

JUST A SPOONFUL OF SUGAR MAKES THE BATTERIES PRICE GO DOWN. Great technology, do hope it works well . Keep smiling everyone

[PowerStudios]

Generally a good and well thought out video - But it's "watt-hours per kg" not "watts per kg". (Watt is a measure of rate of use of energy whereas Watt-hours or Wh for short are a measure of energy)

[chris]

Love hearing about new battery tech, and yes, the energy/mass density of 500Wh/kg + is a much talked about threshold for cleaning up aviation. The key as always is moving from the lab to manufacture, many don't make it. So not so much the science but the engineering and subsequent economics, does it add up? I don't know enough about their work to know if they can succeed but am hopeful. Who exactly would you target your investment at? This is the decade to do it.

[marcof.]

Electric aviation was the first thing that came to my mind when you said “500Wh/kg”. Sounds great! Looks like we will have a battery chemistry for every use case one could possibly think of. Soooo, for what do we need all these other technologies again? Like f.e. … hydrogen? What surprises me the most is how right Tony Seba has been so far with all his predictions.

[mfb]

Sulphur is theoretically a really good electric storage but it has always had issues in passivation of particles. I did some basic research on sulphur electrodes in 1990’s and was looking for polymer binders to keep suplhur not passivating and becoming fragmented. Sulphur has some issues when it is creating various bounds with oxygen. Inside electronic device such as battery it is not rare. Google sulphur trioxide and know why we are not using it in batteries. 😆

Anyway. Lithium sulphur cells are ”a thing”. Issues are the same. Cycle stability. If it would be such a easy task we’d be already driving around with batteries from Iceland.

[quantumworkscorporation]

Keep up the good work, we need latest cells that are actually in production

[yggdrasil]

Even if Li-Su lasts 2000x cycles that's going to allow for far less charging anyway, so would be equivalent to the 4000x cycles for LFPs. Also swapping out new for old could be part of the design component of the car, and could take as little as 10 minutes and cost very little in terms of labour.

[stuartirwin]

I think you mean 500 watt hours per kg, not 500 watts per kg. It seems to be common to mix these units up.

[brunosmith]

The world has always been waiting for Li-Ion technology to hit "The Sweet Spot".

[davidholder]

I honestly don’t know enough to dispute what you are suggesting. Your reasoning is very sound concerning the airline industry. Was a very interesting video. Thanks I will continue to follow you to learn more.

[joe]

It's going to be pretty funny when sugar-salt batteries is what solves our energy storage crisis

[mrbizi]

Nice call out on the aviation industry needing the 500w / kilo. Weight is a bit challenge. We’ll need designs with replaceable battery packs to enable “quick change” for faster turn around while at the airport gate, etc.

[jstoltz]

It seems like an overly heavy focus on transportation needs, more specifically “people conveyance”. Perhaps putting some of these storage options into a Tesla MegaPac type system connected to a solar array such that a thermal runaway issue doesn’t put a human at risk while driving or carrying it in their pocket. If it turns out to be exceptionally well suited for storage with a small(ish) risk of fire, use in a solar/wind farm might be an acceptable cost of doing business (at least for another ten years while we learn more. Just a random thought. Great channel, thanks for helping us all.

[chrisborns]

I studied these batteries in 2010 this making new breakthroughs has me losing my mind! I couldn't be more excited

[jameskoran]

I think Form Energy is on to something with their Iron Air tech. However, this is only practical for large scale storage due to weight. Impressive though!

[messenger]

You're not wrong. It's just early. Proof of concept is still a long way from testing viability and manufacture. But yes, it's quite promising.
