Twaddle. You have to 'push' the current through against a potential 'hill' (the battery voltage, on charge). To do that requires work, so you are putting in _electrical_energy_. The energy is mostly stored in chemical form and partly dissipated as heat.

Energy is charge times potential (coulombs times volts = joules).
