This, and possibly more importantly: how well does it retain effectiveness under wear/adverse circumstances?

It seems really promising, but if we up the cost of battery production and hence make them more expensive, then it would be nice to know it will still work after extended use.

I dunno. I skimmed the intro of the journal article and they say they achieve

> high conductivity of SRL under standard battery operation

but I don’t know if the losses are truly negligible. I think we need someone who knows more about batteries.
