  • Advances of aqueous rechargeable Lithium-Ion Battery: A review
    Journal of Power Sources, 2015
    Co-Authors: Nurhaswani Alias, Ahmad Azmin Mohamad
    Abstract:

    The electrochemical characteristic of the aqueous rechargeable Lithium-Ion Battery has been widely investigated in efforts to design a green and safe technology that can provide a highly specific capacity, high efficiency and long life for high power applicatIons such as the smart grid and electric vehicle. It is believed that the advantages of this Battery will overcome the limitatIons of the rechargeable Lithium-Ion Battery with organic electrolytes that comprise safety and create high fabricatIon cost issues. This review focuses on the opportunities of the aqueous rechargeable Lithium-Ion Battery compared to the conventIonal rechargeable Lithium-Ion Battery with organic-based electrolytes. Previously reported studies are briefly summarised, together with the presentatIon of new findings based on the conductivity, morphology, electrochemical performance and cycling stability results. The factors that influence the electrochemical performance, the challenges and potential of the aqueous rechargeable Lithium-Ion Battery are highlighted in order to understand and maintained the excellent Battery performance.

  • thermal runaway caused fire and explosIon of Lithium Ion Battery
    Journal of Power Sources, 2012
    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. This paper reviews the Lithium Ion Battery hazards, thermal runaway theory, basic reactIons, thermal models, simulatIons and experimental works firstly. 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. Some perspectives and outlooks on safety enhancement for Lithium Ion Battery are proposed for the future development. Language: en

  • Catastrophe analysis of cylindrical Lithium Ion Battery
    Nonlinear Dynamics, 2010
    Co-Authors: Qingsong Wang, Ping Ping, Jinhua Sun
    Abstract:

    The thermal runaway reactIons in a Lithium Ion Battery cause its temperature and pressure to increase sharply and even as a result explode in the worst conditIons. This kind of explosIon is thought of as a catastrophe phenomenon. The energy conservatIon equatIon for the discharging process of Lithium Ion Battery was produced, to disclose the catastrophic mechanism of thermal runaway explosIon. By the dimensIonless method, the swallowtail catastrophe potential functIon of the Lithium Ion Battery was obtained. The control variables of the potential functIon were discussed further and the thermal runaway zones and non-thermal runaway zones were obtained. The results indicate that the thermal runaway of Lithium Ion Battery is a swallowtail catastrophe in essence, and thus the control methods of Lithium Ion Battery thermal runaway can be designed from the view point of catastrophes in the future.

  • Lithium Ion Battery Fire and ExplosIon
    Fire Safety Science, 2005
    Co-Authors: Qingsong Wang, Jinhua Sun, Guanquan Chu
    Abstract:

    With the extensive applicatIons of Lithium Ion batteries, many batteries fire and explosIon accidents were reported. Base on the combustIon triangle theory, the combustIon triangle contributIons of Lithium Ion Battery were analysed. By using C80 micro calorimeter, the thermal behavior studies on the materials show that the flammable electrolyte, oxygen generated by charged cathode and anode decompositIon, and exothermic reactIon heats form the combustIon triangle together. The thermal runaway of working materials in Lithium Ion Battery system was studied with common used Battery materials, and the no return temperature TNR was calculated is 75 o C and the self-accelerating decompositIon temperature (SADT) is 66.5 o C. Further analysis shows that the Lithium Ion Battery reactIon chain according with Domino effect, therefore, the Lithium Ion Battery fire and explosIon developing sequences was drawn by Domino chain. The Domino chain explains the fire and explosIon developing process perfectively, and then the countermeasures can be taken by breaking the Domino chain for the safety of Lithium Ion Battery.
