no, because:

lithium ion batteries 0.36–0.875 MJ/kg

Jet-A: 42.80 MJ/kg

quick googling says a 747-8 has a 239,000 liter fuel capacity, so the energy stored in full tanks is 10,229,200MJ

I don't know of any battery or hydrogen fuel cell type technology that can approach anywhere NEAR ten million megajoules stored in the same weight.
