No it would not be possible. You're talking about something like a perpetual motion machine.
If you used a battery to power an internal colandria to generate steam, then used that steam to power a turbine, you would have energy losses. Those losses would prevent you from recharging the battery, powering the colandria, and propelling the ship.
