All we can do with batteries is improve the efficiency of known chemistry towards the theoretical max. Also improve cycle life and charge cycle degradation characteristics.
Right now mature (commercially viable) battery technology can get to around 200 W hours/KG. Theoretical chemical limit is about 1,000 Wh/KG.
Jet A is 12,000 Wh/KG...
There's no uncharted territory in molecular chemistry which is going to provide an order of magnitude+ improvement in specific energy. The answer is going too be biofuel.
There's other ways to store power and to generate power. A large capacitor is one way but I don't know about the weight and controlled release or stored energy.
Fuel cell for generating electric power is a possibility as well.
