  • safe positive temperature coefficient composite cathode for lithium ion battery
    Journal of Power Sources, 2012
    Co-Authors: Hai Zhong, Chan Kong, Caimao Zhan, Hui Zhan, Yunhong Zhou
    Abstract:

    Abstract Ethylene vinyl acetate (EVA) based positive temperature coefficient (PTC) material with a transition temperature ( T c ) of 90 °C is proposed and successfully fabricated in this study. It is further introduced into LiFePO 4 cathode by directly mixing it with LiFePO 4 powder, binder and conductive carbon or sandwiching it between the current collector and LiFePO 4 electrode membrane. Thus obtained LiFePO 4 /PTC composite electrodes both show a self-current-limiting effect at 90 °C. The electrochemical properties of the LiFePO 4 /PTC composite electrodes are determined in terms of galvanostatic charging/discharging, cyclic voltammograms and electrochemical impedance spectroscopy measurements. Comparing with bare LiFePO 4 electrode, both LiFePO 4 /PTC composite electrodes show no degradation in cycling stability, rate capability and electrochemical Kinetic Property at room temperature. The results indicate that the proposed LiFePO 4 /PTC composite electrode with the suitable T c of 90 °C can effectively prevent thermal runaway before the occurrence of side reactions and better protect lithium ion battery during the abnormal temperature increasing.
