Abstract

Spinel LiMn2O4 was synthesized by solid-state method,using Mn2O3 as manganese source. By X-ray diffraction, scanning electron microscope and electrochemical performance test, effects of impurity calcium from manganese source.ie. MnCO3on the electrochemical properties of spinel LiMn2O4 weresystematically studied. The results showed that allsamples with different contents of impurity calciumwere indexed to spinel phase with the cubic space of Fd3m, and no impurity phase was detected; the particle size and morphology of sampleswere not obviously different; when the contents of impuritywere low, the first charge-discharge capacity remained almost unchanged with the increase of calcium; and in contrast, itdistinctlydecreased. The results also showed that the cycle-stability of LiMn2O4 was improved collaboratively.
