摘要/Abstract

摘要： The spinel LiMn2O4 cathode material was synthesized with the solid-state reaction method.
Four manganese compounds including electrolytic manganese dioxide (EMD), MnCO3, Mn3O4 and
nano-EMD were used as Mn sources while LiOH.H2O was used as the uniform Li source. The
crystal structure characteristics of these samples produced were investigated by means of
XRD, SEM, particle size distribution analysis and specific surface area testing. Their
electrochemical properties were also studied by comparing their specific capacity, charge
and discharge efficiency and cycle performance.
