Db. Jiang et al., Influence of surface treatments of LiMn2O4 powder with Ag on charge-discharge characteristics I. Ag coating, ELECTROCH, 67(4), 1999, pp. 359-363
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.
