Secondary rechargeable batteries
A secondary or rechargeable battery ( as opposed to a primary battery) is a non-rechargeable, single-use battery that acts as a galvanic cell when it is discharging, as it is converting chemical energy to electrical energy in a redox reaction, but acts as an electrolytic cell when it is being charged as it is converting electrical energy to chemical energy. Electrolysis is the process by which ionic substances are broken down into simpler substances when an electric current is passed through them, thus recharging the battery's electrical potential.
