Boron doped graphite is reported to be potentially useful for lithium ion battery anodes, gas absorbers and advanced electronic materials.  Computational and experimental studies indicate that boron, when doped into graphite, creates a low lying acceptor level that facilitates electron transfer from lithium. Boron addition to graphite at high temperatures (>2000 oC) can improve graphitization, which is believed to be the reason for long cycle life and improved safety of boron doped graphite anodes. However, high temperatures are needed for graphitization to occur. Rather recently, lower temperature treatments of graphite with boric acid in solid or solution state were shown to provide similar benefits to higher temperature synthesis. In this paper we review some of the work on boron doped graphite anodes, including recent advances in this promising research area.
