Battery and Fuel cell Technology

General Aspects of Battery

Battery is a device consisting of one or more electrochemical cells with external connections connected to energize the electrical devices. A battery has a cathode, and an anode. The name "battery" commonly denoted to a device composed of multiple cells, yet the procedure has advanced to additionally include devices consisting of a single cell. Batteries are categorized into primary and secondary types. Primary batteries such as alkaline battery, leclanché cell, lithium battery are irreversibly transforming chemical energy to electrical energy. When the power inside the reactants got exhausted, these batteries such as primary does not restore energy easily. Secondary batteries such as flow battery, fuel cell, lead acid battery etc. can be recharged; that is, they can reverse their chemical reactions by supplying electrical energy to the battery, by restoring their original composition
