对，钛酸锂的胀气问题是个很严重的问题，对于胀气产生的原因现在不是非常清楚，一般认为可能的原因有： 1、LTO吸水比较严重。 2、由于Ti-O键的催化效应可能催化电解液分解. 解决的办法一般从以下入手： 1、在材料表面包覆一层薄的钝化层（比如氧化铝） 2、改善电解液的配方 3、改善化成制度 虽然钛酸锂存在这一问题，但由于他有诸多的优点（安全性能高，循环性能好等），还是吸引了科研工作者的广泛关注，随着研究的深入，相信会解决这一问题 |

Flatulence for lithium titanate is a very serious problem, and what is reason for producing flatulence is not so clear. Anyway, it is generally believed that the possible reasons are as follows: 1, the serious absorbent for LTO. 2, the catalytic effect of Ti-O bond which could make catalyzed decomposition of the electrolyte. The possible solution may be based on the following methods: 1, A surface coated with a thin layer of passivation layer (such as alumina); 2, to improve the electrolyte formula; 3, to improve its chemical synthesis methods. Lithium titanate, which has such problem while is of great many advantages (high safety performance and cycle performance, etc.), has attracted scientists' extensive attention, and it was believed that such problem will be solved by further research. 仅供参考。  |
