石墨氮化碳（gCN）可以进行锂插入反应，适用于锂离子电池阳极。结果表明，gCN的锂容量大大低于理论预期，因此研究了添加导电石墨（CG）以提高性能的gCN的性能。电极的锂吸收量随CG含量的增加而增加，但容量从未超过石墨。结果表明，通过导电途径的电子传递是有限的。10% gCN的Li+吸收率与石墨电极相似，表明gCN确实在决定存储容量方面起作用。
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.
