Abstract
AbstractBatteries are the major power sources for portable electronic devices and toys. They are also used in automobiles for starting, lighting, and ignition (SLI batteries). At present, the worldwide battery market exceeds $30 billion per year. Rapid technological advances and miniaturization in electronics have created an ever‐increasing demand for compact, lightweight batteries. For example, popular portable electronic devices such as cellular phones, laptop computers, and camcorders require batteries of high energy density. Additionally, a need for more efficient use of available energy resources as well as air‐quality control have created enormous interest in electric vehicles. For example, the major automobile manufacturers around the globe are engaged in developing advanced batteries for electric vehicles in response to increased environmental regulations and legislative mandates. The advanced and high energy density batteries have become possible due to the discovery and development of smart materials and processes. This article, after providing a brief introduction to the basic electrochemical concepts and the principles involved in batteries, presents the materials and electrochemical aspects of high energy density (lithium‐ion) batteries.
