Maybe a nanopore/nanostructure battery[1,2]? They are touted to bring near-capacitor charge/discharge rates from fairly traditional chemistry. This specific application leaves a few questions, though: 1: What is the actual capacity of the battery demonstrated? If it has a high C but low capacity, this isn't really notable. The paper [1] indicates that total charge capacity is a function of how fast the battery is charged; what tradeoff are they making? 2: How many charge cycles is this battery capable of at those rates? 3: What thresholds are they putting in place for temperature, and are all the components of the phone rated for repeated thermal cycles to those levels and back to ambient? 4: What is the failure mode for this battery? Outgassing? What compounds are released in overcharge? [1] - http://www.nature.com/nnano/journal/v9/n12/abs/nnano.2014.247.html http://www.nature.com/nnano/journal/v9/n12/abs/nnano.2014.24...
