Three V or 4 V Li---Mn composite as cathode in Li batteries prepared by LiNO3 method as Li source

Four types of lithium-containing manganese oxide obtained by the LiNO3 method, namely (i) Li0.3MnO2 obtained from 1/3 mixture of Li/Mn molar ratio heated at 320–350 °C; (ii) LixMn2Oy obtained from the mixture with 1.2–1.8 molar ratio of LiNO3/MnO2 heated at 300 °C; (iii) the spinel LiMn2O4 by 1/2 mixture of LiNO3/MnOOH and (iv) non-stoichiometric spinel Li1+xMn2O4, will be reported and their electrochemical behaviour in lithium cells will be described.
