DOE Explains...Batteries | Department of Energy
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.

Potential energy is one of several types of energy that an object can possess. While there are several sub-types of potential energy, we will focus on gravitational potential energy. Gravitational potential energy is the energy stored in an object due to its location within some gravitational field, most commonly the gravitational field of the Earth.
Why is energy absorbed by the battery when the plates of a
Now lets focus on the question "Why does the battery absorb energy in the first place?". When the plates of the capacitor are pulled apart, its capacitance or the ability to store charge decreases and so the magnitude of charge on either plates reduces.
