摘要
Li4Ti5O12是一种锂离子电池负极材料,它的优势是具有较高的负极电压,为电池带来可靠的安全性。然而,目前Li4Ti5O12仍然存在着电子传导速率低和离子扩散速率慢的问题,制约了其高倍率性能的发展。本论文主要从构建Li4Ti5O12的微纳结构、构建Li4Ti5O12/碳的复合结构和构建Li4Ti5O12的纳米阵列结构,综述了解决Li4Ti5O12电子传导速率低和离子扩散速率慢问题的方法,并对Li4Ti5O12电极的未来发展前景进行了分析与展望。
Li4Ti5O12 is a kind of negative material for lithium ion batteries. Its advantage is that it has high negative voltage, which brings reliable safety for batteries. However, there are still some problems in Li4Ti5O12, such as low electron conduction rate and slow ion diffusion rate, which restrict the development of its high rate performance. In this paper, mainly from perspective of micro-nano structure of Li4Ti5O12, the composite structure of Li4Ti5O12/carbon and the nano-array structure of Li4Ti5O12, the methods to solve the problems of low electron conduction rate and slow ion diffusion rate of Li4Ti5O12 are summarized and the future development prospects of Li4Ti5O12 electrode are analyzed and prospected.
