Lithium ion batteries have higher energy density. Recently, lithium ion batteries are beginning to be utilized in industrial applications. As for the lithium ion batteries in industrial applications, many different performances are required as well as energy density. It is important to develop according to the own requirement for their application. Energy density of Lithium ion batteries using LTO anode is smaller than that of conventional ones. But the batteries with LTO anode have unique features. In this reports, the features and application of lithium ion batteries using LTO anode is explained.
