Abstract
Nanosized (10~50 nm) cathode material Li2MnO3 was prepared for with MnSO4·H2O，KMnO4 and Li-
OH aqueous solution as the precursor via single-step hydrothermal reaction by controlling the reaction
time, proportion of processor, and the reagent concentration. The prepared materials were well crystallized
and exhibited a monoclinic Li2MnO3 structure with a space group of C2/m phase. The electrochemical performance
of the material was tested at current density of 60 mAg-1 (1/4 C) between 4.3V and 2.0 V at room
temperature, showing good electrochemical properties with the initial discharge capacity of 243 mAh·g-1,
because it was more exposed to the electrolyte due to its nanostructure.
