铬离子掺杂锰酸锂电池高温溶解性的图像分析
Image analysis of chromium doping on LiMn2O4 spinel high temperature solubility
摘要
Abstract
The dissolution behavior of Cr and Mn ions in LiMn2-xCrxO4 under different temperatures was studied by scanning electron microscopy.When the LiMn2-xCrxO)4 powder was immersed in an electrolyte containing LiPF6,the chromium and manganese ions were dissolved.Chromium ion in LiMn2-xCrxO4 was increased.Under the normal temperature and high temperature conditions,the amount of dissolved manganese ions were significantly reduced.This shows that in LiMn2O4 doped chromium ions,the dissolution of manganese ions is inhibited at high temperatures,and therefore a decline in capacity is lead.In addition,the amount of dissolved quantity of chromium ions and manganese ions would be significantly increased with the increasing of the immersion temperature.This shows that temperature plays a key role in the dissolution of Cr doped and non doped LiMn2O4.关键词
