A galvanic cell, also known as a voltaic cell, is an [electrochemical cell](/entry/_3VVHFqLRvQtI1YzMP7OxVV) that generates electrical energy through chemical reactions, specifically redox reactions. Galvanic cells are the building blocks of [batteries](/entry/_5HYZND6114KVUtCGjFC8mT).

An electrolytic cell is a [cell](/entry/_3VVHFqLRvQtI1YzMP7OxVV) containing an electrolyte in which an applied voltage causes a reaction to occur that would not occur otherwise (such as the breakdown of water into hydrogen and oxygen).

An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions. Those which generate electrical energy are called galvanic cells, and are the principal buidling block of [electric batteries](/entry/_5HYZND6114KVUtCGjFC8mT).

A battery is an assembly of one or more [galvanic cells](/entry/_2azW7zIxVCeNrbXuRrsm2k) that can be used to power electrical devices using stored energy. The cells are packaged in a container that provides external electrical external connections, usually a positive and a negative terminal.

Battery

A primary cell is a [galvanic cell](/entry/_2azW7zIxVCeNrbXuRrsm2k) that is designed to be used only once, such as the cells that comprise disposable batteries.
