Energy Storage. Energy transfers also allow us to store energy for future use - for example, when charging a battery or winding up a clock. Batteries convert a chemical reaction into electrical energy. An electrolyte oxidises the anode, and the cathode reacts with the oxidised electrolyte to produce electricity.
