Abstract The Li4Ti5O12/graphitic carbon nitride (g-C3N4) composite was fabricated via a solvothermal method followed by heating treatment at 700 °C for 5 h. In this method, g-C3N4 acted as a support to enhance the electronic conductivity of Li4Ti5O12. When tested as anode materials for lithium ion batteries, the as-synthesized Li4Ti5O12/g-C3N4 composite displays a reversible capacity of as high as 150.8 mAh/g with a capacity retention of 86.8% at 0.5 C after 502 cycles. The cycling performance of the composite is enhanced, which could be attributed to the existence of g-C3N4 support.

Li4Ti5O12/g-C3N4 复合材料具有改进的锂存储能力

摘要 Li4Ti5O12/石墨氮化碳（g-C3N4）复合材料是通过溶剂热法制备的，然后在700°C下热处理5小时。在该方法中，g-C3N4 作为载体来增强 Li4Ti5O12 的电子导电性。当作为锂离子电池的负极材料进行测试时，合成的 Li4Ti5O12/g-C3N4 复合材料显示出高达 150.8 mAh/g 的可逆容量，502 次循环后在 0.5 C 下的容量保持率为 86.8%。复合材料的循环性能增强，这可能归因于 g-C3N4 载体的存在。
