VANADIUM BRONZE RICH IN LITHIUM AS POSITIVE MATERIAL FOR SECONDARY LITHIUM BATTERY
Abstract:
Vanadium bronze rich in lithium(Li6V5O15)was prepared from Li2CO3 and V2O5 at 680℃. The charge-discharge behaviour of the bronze electrode was investigated in LiAsF6-PC electrolyte at various current densities.Li/bronze cell showed a high specific capacity, and more than 340Ah/kg was obtained at 0.2mA/cm2 and 1.0V cut-off voltage. The X-ray diffraction results showed that the structure of the new bronze was stable for lithium insertion.AC impedance data of Li/bronze cell showed that the cathodic process was mainly controlled by diffusion of Li in the bronze.
