Abstract Li4Ti5O12/Ti3C2Tx nanocomposite was prepared by high temperature calcination method using Ti3C2Tx and LiOH as raw materials. The developed nanocomposite demonstrated excellent rate capability and capacity retention. It delivers a reversible capacity of 236 mAh/g at a current density of 50 mA/g and had a relatively high specific capacity of 500 mA/g and 4000 mA/g, which is significantly better than pure Ti3C2Tx and LiTiO2. The exceptional electrochemical performance of Li4Ti5O12/Ti3C2Tx electrode can be attributed to the improvement of electronic conductivity by Ti3C2Tx and nano-size of Li4Ti5O12 particles in the Li4Ti5O12/Ti3C2Tx composite.

新型Li 4 Ti 5 O 12 /Ti 3 C 2 T x 纳米复合材料作为锂离子电池的高倍率负极材料

摘要 以Ti3C2Tx和LiOH为原料，采用高温煅烧法制备了Li4Ti5O12/Ti3C2Tx纳米复合材料。开发的纳米复合材料表现出优异的倍率性能和容量保持率。它在 50 mA/g 的电流密度下提供 236 mAh/g 的可逆容量，并具有相对较高的 500 mA/g 和 4000 mA/g 比容量，明显优于纯 Ti3C2Tx 和 LiTiO2。Li4Ti5O12/Ti3C2Tx 电极优异的电化学性能可归因于 Ti3C2Tx 提高电子电导率和 Li4Ti5O12/Ti3C2Tx 复合材料中 Li4Ti5O12 颗粒的纳米尺寸。
