A TiS2 composite cathode for Lithium polymer battery was developed. We investigated the a.c. impedance response as a function of temperature and charge/discharge cycling process and charge/discharge characteristics of TiS2 composite/solid polymer electrolyte/Li cells. The passivation layer resistance of the Li/solid polymer electrolyte interface at 25 degrees C was 292 Omega cm(2). The total resistance of the TiS2 bulk and the TiS2/solid polymer electrolyte interfaces was 96 Omega cm(2). The cell resistance significantly decreased at 60 degrees C. The discharge capacity of the TiS2 composite cathode with 40 wt.% solid polymer eletrolyte was 173 and 146 mAh/g based on TiS2 at cycle nos. 1 and 20 at 25 degrees C, respectively. The utilization TiS2 at the discharge processes nos. 1 and 20 at 25 degrees C were 72 and 61%, respectively TIS2 composite cathode with 40 wt.4% solid polymer electrolyte showed better capacity with cycling.
