The Current Move of Lithium Ion Batteries Towards the Next Phase

Abstract Application targets of lithium ion batteries (LIBs) are moving from small‐sized mobile devices of information technology to large‐scale electric vehicles (xEVs) and energy storage systems (ESSs). Environmental issues and abruptly increasing power demands are pushing high performance energy storage devices or systems onto markets. LIBs are one of the most potential candidates as the energy storage devices mainly due to their high energy densities with fairly good rate capabilities and a fairly long cycle life. As battery systems become larger in terms of stored energy as well as physical size, the safety concerns should be more seriously cared. Each application target has its own specification so that…
