  • Advanced intermediate temperature sodium Copper Chloride battery
    Journal of Power Sources, 2014
    Co-Authors: Li-ping Yang, Xiaomin Liu, Yiwei Zhang, Hui Yang, Xiaodong Shen
    Abstract:

    Abstract Sodium metal Chloride batteries, also called as ZEBRA batteries, possess many merits such as low cost, high energy density and high safety, but their high operation temperature (270–350 °C) may cause several issues and limit their applications. Therefore, decreasing the operation temperature is of great importance in order to broaden their usage. Using a room temperature ionic liquid (RTIL) catholyte composed of sodium Chloride buffered 1-ethyl-3-methylimidazolium Chloride–aluminum Chloride and a dense β″-aluminates solid electrolyte film with 500 micron thickness, we report an intermediate temperature sodium Copper Chloride battery which can be operated at only 150 °C, therefore alleviating the corrosion issues, improving the material compatibilities and reducing the operating complexities associated with the conventional ZEBRA batteries. The RTIL presents a high ionic conductivity (0.247 S cm−1) at 150 °C and a wide electrochemical window (−2.6 to 2.18 vs. Al3+/Al). With the discharge plateau at 2.64 V toward sodium and the specific capacity of 285 mAh g−1, this intermediate temperature battery exhibits an energy density (750 mWh g−1) comparable to the conventional ZEBRA batteries (728–785 mWh g−1) and superior to commercialized Li-ion batteries (550–680 mWh g−1), making it very attractive for renewable energy integration and other grid related applications.

  • An intermediate temperature sodium Copper Chloride battery using ionic liquid electrolyte and its degradation mechanism
    Ionics, 2019
    Co-Authors: Congsu Niu, Yonghua Wan, Shuai Ma, Yiwei Zhang, Hui Yang, Xiaomin Liu
    Abstract:

    Sodium metal Chloride batteries possessing many merits, such as high energy density and long cycle life, are usually operated above 300 °C. Such high operating temperature may accelerate corrosion and aging, increase operating complexity, require an extra thermal management system, and limit their widespread applications. Lowering the working temperature may alleviate these issues and broaden their usage. Herein, a sodium Copper Chloride battery running at 175 °C is designed with the room temperature ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide dissolved with sodium trifluoromethanesulfonate, to replace sodium Chloride saturated sodium tetrachloroaluminate as the catholyte. The cathode delivers the high specific capacity of 141.4 mAh g−1 and the high energy density of 374.7 Wh kg−1. In addition, the capacity retention reaches 92.1% after 50 cycles with an average coulombic efficiency as high as 99.6%. The examination of the cathode and solid electrolyte collected after 50 cycles shows that the degradation mechanism of the battery is attributed to (1) the accumulation of a large amount of non-conductive Copper Chloride in the three dimensional network structure of the Copper foam and (2) the loss of β″-alumina in the solid electrolyte during the charge/discharge process.
