Any info on the theoretical capacity of these vs Lithium Ion? I didn't see it in the article. (Obviously it's not a competition, but it'd be nice to have some

Any info on the theoretical capacity of these vs Lithium Ion? I didn't see it in the article. (Obviously it's not a competition, but it'd be nice to have some frame of reference)

According to the paper[1], the prototype has an energy storage capacity of 0.88 Wh/kg, which is about 250 times lower than standard lithium ion cells. [1]: https://onlinelibrary.wiley.com/doi/10.1002/adma.202101328 https://onlinelibrary.wiley.com/doi/10.1002/adma.202101328

The "battery" is actually a capacitor; those tend to have very low energy density compared to batteries, but on the other hand can be charged and discharged very quickly.
