The preparation process and electrochemical properties of LiMn 2 O 4 and LiMn 1.95 M 0.05 O 4 (M = Cr, Ni) were studied. The results show that the decomposition temperature range of xerogel prepared with lithium acetate and manganese acetate as raw materials is large and the decomposition speed is slow. Oxygen consumed is apt to get a prompt supplement during...
