大家好,请教一下,用gromacs跑完锂离子电池电解液体系的分子动力学后,怎么去分析锂离子在溶液中配位结构呢?去知道锂离子的溶剂化结构有哪些,以及不同结构的占比是什么样的呢?之前请教有前辈说写TCL脚本可以实现,大家能否给个类似的参照呢?
比如说文献的描述:
MD simulations were conducted to reveal the solvationstructure of Li+ in different mixtures of two solutions. In the 1mol L−1 LiTFSI-EC+DMC solution, the three most dominantsolvation structures are Li(EC)2(DMC)(TFSI)2, Li(EC)-(TFSI)4, and Li(EC)4(TFSI), with contents of 17.39%,8.30%, and 7.90%, respectively. Overall, the coordinationnumbers of Li+ with EC, DMC, and TFSI− are 2.37, 0.76, and2.77, respectively (Figure S4 and Table S2), while in 1 mol L−1LiTFSI-EC+EGD solution, the three most dominant solvationstructures are Li(EC)2(EGD)(TFSI)2 (12.74%), Li-(EC)3(EGD)(TFSI)2 (9.14%), and 1Li(EC)3(EGD)(TFSI)(8.76%); the respective coordination numbers with EC, EGD,and TFSI− are 2.28, 1.08, and 2.55 (Figure S7 and Table S3).;
