Abstract
Surface treatment of LiMn2O4 powder as a cathode material for lithium ion b attery was done using the reaction that AgNO3 decomposes to Ag at high temp erature. The surface characteristics were studied by means of a TEM and a p otentiometric titrator. The charge-discharge performances of the LiMn2O4 po wder were tested at a constant current density of 0.50 mA cm(-2), and at 30 degrees C and 60 degrees C. The results showed that the surface treatment can significantly improve the charge-discharge performance.
