Abstract
In lithium ion batteries, graphite and graphitized carbonaceous materials have been mainly used as negative electrodes because of their acceptable high capacity, very flat potential as low as Li metal, etc. One of the problems for graphite negative electrode is the use of propylene carbonate (PC)-based electrolyte. In PC-based electrolyte, electrochemical lithium ion intercalation into graphite can not take place. PC-based electrolyte gives wider potential window and lower melting point compared with ethylene carbonate-based electrolyte. Therefore, many researchers have focused the use of PC-based electrolyte. Here we summarized the work on graphite electrode in PC-based electrolytes and discussed the use of PC-based electrolyte for lithium ion batteries.
