概要 Lithium insertion mechanism into anodic carbon of lithium ion battery and the performances of lithium ion battery such as charge/discharge capacity and potential, cycle stability were measured and cor...related to the structure of carbon. Lithium ion intercalates into the graphene layers of graphite, reversible capacity being as high as 372mAh/g theoretically. However, non-graphitized carbon showed very different performances from that of graphite. Based on the charge/discharg performances of several kinds of carbon, Li insertion models for carbons heat-treated at low temperature are proposed in this review. The microstructure and sub-micro voids in carbon heat-treated at lower temperature play a very important role to store Li in carbon. Such approaches will be very helpful to design new carbon for higher performance Li ion battery.続きを見る
