摘　　要：尖晶石型钛酸锂(Li4Ti5O12)负极材料因其优异的循环和倍率性能引起了人们广泛的研究兴趣。但是基于Li4Ti5O12负极的全电池具有严重的胀气现象,高温下尤其明显。对于钛酸锂的大规模应用,解决破坏性气体的产生一直是一项关键的技术难题。本文综述了近年来有关钛酸锂胀气的研究进展,对气体的主要成分、影响因素以及产气机理进行了简要的总结,并提出可能的解决办法。Spinel Li4Ti5O12 anode has attracted recent interests due to its excellent rate and cycling performance. However, the full battery based on Li4Ti5O12 anode suffers from severe flatulence, especially at high temperatures. This has become the greatest technologic challenge. For the large-scale application purpose, we should solve the swelling problems. This paper was to review recent development on this aspect, i.e., the main components of the generated gas, the influencing factors and the gas production mechanism. In addition, several possible solutions to suppressing gas generation in Li4Ti5O12-based batteries were also proposed.
