Electrolysis is a technique that uses a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction; commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis of water produces hydrogen and oxygen.

A process for depositing a layer of metal onto an electrode by electrolysis
