    Co-Authors: Qingsong Wang, Ping Ping, Xuejuan Zhao, Chunhua Chen
    Abstract:

    Lithium Ion battery and its safety are taken more consideratIon with fossil energy consuming and the reductIon requirement of CO2 emissIon. The safety problem of Lithium Ion battery is mainly contributed by thermal runaway caused fire and explosIon.

The general theory is proposed and detailed reactIons are summarized, which include solid electrolyte interface decompositIon, negative active material and electrolyte reactIon, positive active material and electrolyte reactIon, electrolyte decompositIon, negative active material and binder reactIon, and so on. The thermal models or electrochemical-thermal models include one, two and three dimensIonal models, which can be simulated by finite element method and finite volume method. And then the related preventIon techniques are simply summarized and discussed on the inherent safety methods and safety device methods.

  • Lithium Ion transfer at the interface between Lithium Ion conductive ceramic electrolyte and liquid electrolyte a key to enhancing the rate capability of Lithium Ion batteries
    Journal of The Electrochemical Society, 2005
    Co-Authors: Takeshi Abe, Fumihiro Sagane, Masahiro Ohtsuka, Yasutoshi Iriyama, Zempachi Ogumi
    Abstract:

    In this study, Lithium-Ion transfer through the electrode/electrolyte interface was examined using a model interface composed of a Lithium-Ion-conductive ceramic and liquid electrolytes to focus on Lithium-Ion transfer. Lithium-Ion transfer resistances at the interface and their activatIon energies were evaluated by impedance spectroscopy. The activatIon energies were quite large and consistent with the interactIon between Lithium-Ion and solvents in an electrolyte as determined by a theoretical calculatIon.

  • Lithium Ion transfer at an electrolyte heat treated nongraphitizable carbon electrode interface
    Journal of The Electrochemical Society, 2005
    Co-Authors: Takayuki Doi, Takeshi Abe, Yasutoshi Iriyama, Zempachi Ogumi
    Abstract:

    To elucidate the kinetics of Lithium Ions at a nongraphitizable carbon electrode, Lithium-Ion transfer at the interface between a heat-treated nongraphitizable carbon electrode and a liquid electrolyte was studied by ac impedance spectroscopy. In Nyquist plots at potentials below 0.9 V, a semicircle assigned to charge-transfer resistance due to Lithium-Ion transfer at the heat-treated nongraphitizable carbon electrode/electrolyte interface was observed in the intermediate frequency regIon. The value of the resistance was effectively decreased by heat-treatment of the nongraphitizable carbon. The temperature dependence of the resistance showed Arrhenius-type behavior, and the activatIon energy for Lithium-Ion transfer was evaluated. Although a high activatIon barrier of 70 kJ mol - 1 was noted at the untreated nongraphitizable carbon electrode/electrolyte interface for Lithium-Ion transfer regardless of the electrolyte used, heat-treated nongraphitizable carbon gave a lower activatIon barrier depending on the electrolyte used. Based on the present results and by considering the structural relaxatIon of nongraphitizable carbon upon heat-treatment, the rigid structure of nongraphitizable carbon may significantly affect Lithium-Ion transfer kinetics at a nongraphitizable carbon electrode/electrolyte interface.

  • Lithium Ion transfer at the interface between Lithium Ion conductive solid crystalline electrolyte and polymer electrolyte
    Journal of The Electrochemical Society, 2004
    Co-Authors: Masahiro Ohtsuka, Fumihiro Sagane, Yasutoshi Iriyama, Zempachi Ogumi
    Abstract:

    Lithium-Ion transfer at the interface between the Lithium-Ion-conductive ceramic of La 0.55 Li 0.35 TiO 3 (LLT) and the polymer electrolyte of polyethylene oxide (PEO) complexed with LiCF 3 SO 3 (PEO-LiCF 3 SO 3 ) was studied by ac impedance spectroscopy for the system of Li/PEO-LiCP 3 SO 3 /LLT/PEO-LiCF 3 SO 3 /Li. The impedance ascribed to Ion transfer through the interface was observed. The resistance due to the Lithium-Ion transfer at the interface was larger than those through phases of LLT and PEO-LiCF 3 SO 3 , and the temperature dependence of the interfacial resistances showed Arrhenius-type behavior. The activatIon energy of the interfacial resistances was larger than those for Lithium-Ion conductIon in LLT and PEO-LiCF 3 SO 3 . The design of the Ion-conductive ceramic and the polymer composite electrolytes is discussed based on the results.
