摘要
常温二次Li/TiS_2电池放电时,阴极TiS_2可以形成一系列插入化合物,本实验研究结果发现,在不同条件下,既可以形成文献报导的Li_xTiS_2(d=6.11～6.14(?)),也会形成Li_x(pc)_yTiS_2(d=19.6;14.5(?))三元共插入化合物,TiS_2层距在这样大地膨胀下(大于原层间距1～2倍),脱插后,仍可恢复原来的结构而无严重破坏。
some intercalation compuonds can be formed when the lithium battery is being discharged, which has TiS_2 as cathode material. In present study we found that inserter of the Li_xTiS_2 (d=6.11 to 6.14) has been formed and Li_x(PC)_yTiS_2 (d=14.5; 19.6) as well at the different conditions. After the deinterealation of the inserter, the structure of TiS_2 will be recovered and not be broken, even if the latticeexpansions correspond to 8.8 and 14A.
