Just a Retarded Theory
Electrical transformers (such as wall adapters) are pretty clunky and inefficient and emit harmful EMF radiation. What if there's a better way?
You obviously can't just stick a component into the middle of the circuit that increases the voltage or the amperage. If it increases the voltage at the expense of amperage, where do all those extra electrons holes go? If it increases the amperage, where do all the extra electron holes come from? So obviously you need a completely separate closed circuit, somehow powered by the original, which is exactly what a transformer is but in an inefficient way. Is there a more direct way for Circuit A to pump Circuit B? Perhaps there is. Perhaps there are two.
In a battery voltage is multiplied by hooking them up in series, amperage by hooking them up in parallel. I would imagine this is true for charging, too, in an opposite sense. So..
a) charge the battery in series (this does not need a transformer; charge-pump capacitors, rectifiers, resistors, etc. can be used), while simultaneously draining the battery in parallel, or vice versa.
b) Don't optimize the chemicals for storage capacity; optimize them to efficiently immediately transfer ions or whatever on a constant basis.
..But wait! if we could just capture electrical energy for a second, say in the form of a static charge, in parallel, via Circuit A, and then release it in series, via Circuit B, or vice versa, then couldn't we have Circuit A pumping Circuit B with a V<->A conversion ratio? And wouldn't capacitors be exactly what we need to do this? Just use some more capacitors to alternate between charge and discharge, smooth out the output voltage, etc.
I don't know.. I never really understood electronics.
