The Use of Graphitic Carbon Nitride Based Composite Anodes for Lithium-Ion Battery Applications

摘要

Graphitic carbon nitride (gCN) is shown to undergo lithium insertion reactions applicable with lithium-ion battery anodes. Lithium capacity was found to be substantially lower than theoretically expected, so the properties of gCN composited with conducting graphite (CG), which was added to improve the performance, were investigated. The electrodes exhibited a systematic increase in lithium uptake with CG content, but the capacity never exceeded that of graphite. It is shown that electron transport via conducting pathways was limiting. Li+ uptake for 10% gCN was similar to a graphite electrode, indicating that gCN does play a role in determining the storage capacity.
