What the general public thinks: Car or phone battery.
What the scientists mean: Button cell battery for hearing aids.
Reality: never makes it past the article/news cycle to scalable manufacture.
Indeed. A modern Nissan Leaf with a 62 kWh battery can charge in a little over 11 minutes if you have a 2kV 160 amp line to toss into it. Because you know, it’s completely safe and cool to deal with those kinds of values for the average consumer.
Did you want to add anything to the discussion or just make a snarky comment? I looked through the paper linked in the article and didn’t see a capacity listed.
Our approach directs an alternative Li2S deposition pathway to the commonly reported lateral growth and 3D thickening growth mode, ameliorating the electrode passivation. Therefore, a Li–S cell capable of charging/discharging at 5C (12 min) while maintaining excellent cycling stability (82% capacity retention) for 1000 cycles is demonstrated. Even under high S loading (8.3 mg cm–2) and low electrolyte/sulfur ratio (3.8 mL mg–1), the sulfur cathode still delivers a high areal capacity of >7 mAh cm–2 for 80 cycles.
A 5C charging rate is great, but it’s pretty useless if the battery is too small to be practical.
“Fully charged in 12 minutes” is meaningless without a capacity.

Ok it has the ‘capacity’ to charge in 12 minutes - can you smell smoke?
I agree, the title is pretty useless.
Even something like “Fully charged a double A battery in 28 seconds” would’ve been useful/interesting.

If only the claim were accompanied by a detailed explanation of what the people involved have actually achieved.

No I didn’t want to add anything to the discussion, thank you.
