Abstract

<p>Surface treatment of LiMn2O4 powder as a cathode material for lithium ion battery was done using the reaction that AgNO3 decomposes to Ag at high temperature. The surface characteristics were studied by means of a TEM and a potentiometric titrator. The charge-discharge performances of the LiMn2O4 powder were tested at a constant current density of 0.50 mA cm−2, and at 30°C and 60°C. The results showed that the surface treatment can significantly improve the charge-discharge performance.</p>
