" “shape-conformable” polymer electrolytes." Hmm......Might this not pave the way........
...........for larger volumes of battery in a mobile phone case? By that I mean that if it is possible to (so to speak) "cast" the battery in the casing (as if the casing were a mould) such that the battery occupies otherwise unused volume because is not rigid and not imposing its own shape of the process of constructing the phone it surely would mean more battery in a given case size. IE A larger charge capacity for a phone of a given size than is possible with a conventional rigid battery. In principle one could imagine that the back half of the phone would be in a certain sense "all battery". Just a thought.
