Electrochemical Characteristics and Phase Composition of LithiumManganese Oxide Spinel with Excess Lithium Li1+xMn2O4
Keyword(s):
The paper presents the results of the study of phase composition and electrochemical performance of lithiummanganese oxide spinel with excess lithium of nominal composition of Li1+xMn2O4 obtained by solidphase method. It was established that samples with x = 0.1 and 0.2 were composite materials with LiMn2O4 being the basic phase and Li2MnO3 being the impurity (3 and 7 mas.%, respectively) also comprising trace amounts of MnO2. The composite material with 3% of Li2MnO3 (x = 0.1) retained 80–90% of the initial specific capacity after 300 chargedischarge cycles at C/2, while singlephase stoichiometric spinel LiMn2O4 retained less than 70–75%.
