Lithium Batteries as Electrochemical Sources of Energy

摘要

Energy can be stored in the form of chemical energy and this energy can be converted into electrical energy conveniently in an electrochemical cell and then again released when needed. Several electrochemical cells connected in series, done to increase the practical voltage, are called batteries. The name battery is now, incorrectly, but quite commonly, used even for a single cell and is used interchangeably for a single cell even in this article. There is a number of electrochemical systems that can store and then convert chemical energy to energy electrical, but those based on lithium, the lithium batteries, are the most prevalent and are used as a model system in this tutorial. There are two fundamental types of practical batteries, the primary (that can be used only once) and the secondary versions (that can be recharged after their use).
