Battery Prototype Uses Superextensive Quantum Effects to Charge Faster

Although the term ‘quantum battery’ is a bit of a vague term, the cell that [Kieran Hymas] et al. demonstrate in a recent paper does seem to suggest that it uses quantum effects to charge faster than would otherwise be possible, with this rate increasing faster than its volume, meaning at a superextensive rate. The general idea behind a quantum battery is that these somehow use a quantum effect…
