Jet A (kerosene) has much higher energy density than Li-ion, but electric motors weigh much less & convert stored energy to motion better than combustion engines

FWIW, based on calcs I did 10 years ago, cross-over point for Li-ion beating kerosene is ~400 Wh/kg. High cycle batteries are just over 300 Wh/kg today, but probably exceed 400 in ~5 years.
