If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes). These batteries only work in one direction, transforming chemical energy to electrical energy. But in other types of batteries, the reaction can be reversed.
Lithium based batteries are a versatile way of storing energy; they have one of the highest energy density and specific energy (360 to 900 kJ/kg) among rechargeable batteries. The downside is that, unlike capacitors or other kinds of batteries, they can not be charged by a regular power supply.
