Recharging lithium ion batteries twice as fast with light

Everything large than coin sell has a folded structure that wouldn't get light on the surface area.

They also used a xenon lamp, which implies they need a very powerful light source. Not really something you are going to do with LEDs.

They are also likely complelely ignore energy/heat of the light source.

Not to mention an absurd exaggeration about the current level of battery tech.

"Charging for an electric car on empty typically takes about eight hours".

Sure. Let's pretend faster chargers don't exist.

Interesting as a academic exercise. Really not practical.

You are chemical engineer?

No, and I don't have to be one, to follow this industry closely. You will see some new "revolutionary" battery news on an almost daily, >90% of them never make it from Lab to practical reality.

You also don't need to be a chemical engineer to see the folded structure of normal batteries prevents light access.
Here is a typical EV battery cell. It's rolled in layers:

That kind of structure makes light penetration impossible.

Here is a more plausible option also from this week:

So, you are saying that we find a revolutionary new way to charge these batteries, but we won't or haven't found a new way to build cells, so it's all for naught?

I am saying it's an interesting lab curiosity, and we have these on a near daily basis.

And we have had a better, more practical one, that achieves the same goal just this week.

I'd bet everything I own, that this lab curiosity will never see the light of day in EV charging.

Yes and no. My understanding is that battery tech has been advancing at a steady pace, with significant improvements in cost/safety/capacity/reliability over the past 20-30 years. Entirely new battery tech is rare but some elements of these 'revolutionary' ideas do make it into production. Even if this doesnt get to the point that we're quick charging a portion of our batteries with light somebody might find some other novel use of this discovery.
