Electrochemistry
Electrochemistry describes the interface between chemistry and electrical energy. Obvious examples are production of electrical energy from chemical batteries and the use of electrolysis to carry out chemical processes which do not occur spontaneously. In this pocket recharger, solar energy is used to recharge a set of AA nickel-cadmium batteries.
