Not really an answer to you, just writing it here in case anyone else interested is still reading along:

I looked up some numbers and apart from the practical challenges of making a battery "go boom" in a controlled way it seems like the energy density to even make this a hypothetical option just isn't there. Even the best LiPo batteries don't quite reach 1 MJ/kg while gunpowder has ~3 MJ/kg, and numbers only go up from there for more modern chemical explosives.
