EFFECT OF THE AMOUNT OF WATER ON THE SYNTHESIS OF LiMn2O4, USED AS CATHODE MATERIAL IN LITHIUM-ION BATTERIES

LiMn2O4 with nanostructured morphologies possess rapid kinetics which is favorable for the intercalation of lithium ions in battery electrodes¹. In this work, we have studied the effect of varying the amount of water in the hydrothermal synthesis of nanostructured LiMn2O4 spinel. It was found that t...
