| Abstract: | The use of lithium ion batteries with high power and high capacity, such as used in HEV and EV,is limited due to safety concerns associated with the thermal stability. The over-charging of AA size batteries assembled by using different cathode materials were studied in this work. The results show that the cathode material of LiMn204 shows better over -charging safety;and the cathode material of LiNiO2 embedded in LiCoO2 layer possesses much better over - charging safety. |
