Carbon-carbon composite as anodes for lithium-ion battery systems

Carbon-carbon (C-C) composite has been investigated as an anode for lithium ion battery systems. The composite electrode delivers high reversible capacity and very low irreversible capacity loss. The test results of lithium-ion cells made with the C-C composite anode show many advantages, such as excellent performance and enhanced safety. The performance improvement is achieved because of strong mechanical integrity (cycle life) and absence of binder (shelf life) in C-C composite. The enhancement in safety comes from high thermal conductivity, fire retardant characteristics and an acceptable ability to overcharge and overdischarge. (C) 2001 Elsevier Science B.V.
