Nope. Read about what 'energy density' means and what is energy density of the most advanced batteries/fuel cells comparing to fuel (gas/kerosene/diesel).

In short: when energy density of batteries increases appx 40 times - (as a comparison - when Tesla on a single charge can drive 8000 miles) you have alternative of liquid fuel.

Really doubt it will happen in next couple hundred years.
