Lithium manganese oxide in aspinel structure (LiMn2O4, LMO) is acathode material of nontoxicity,low costs,and ahigh electrochemical potential. In contrast manganese dissolution,structuralfatigue,and microcracks lead to poor cycling stability and capacity fading. Regarding abasic understanding of the influence of the calenderingprocess and the
Lithium nickel manganese cobalt oxide (LiNiMnCoO 2) batteries are made using several different elements commonly found in other Liion batteries and use a combination of nickel, manganese, and cobalt for the cathode. While the exact material ratios vary by manufacturer, the common combinations are usually 60% nickel, 20% manganese, and 20% cobalt.
