| Abstract: | The use of lithium ion batteries with high power and high capacity,such as those used in HEV and EV, is limited due to safety concerns associated with the thermal stability. The thermal stability of AA size batteries assembled by using different cathode materials were studied in this work. The results show that the cathode material of LiMn2O4 has better thermal stability ;and the cathode material of LiNiO2 embedded in LiCoO2 layer possesses high capacity and cycleability. |
