摘要:
传统的Na/金属氯化物电池(ZEBRA)由于使用了氯铝酸钠(NaAlCl4)作为阴极电解质(熔点157 ℃),往往在较高温度(270~350 ℃)下才能运行。本文通过把三氟甲磺酸钠(NaCF3SO3)溶于1-乙基-3-甲基咪唑双三氟甲磺酰亚胺盐(EMIMTFSI)离子液体中,配制0.2 mol/L的NaCF3SO3离子液体电解质。使用循环伏安法、热分析法分别测试离子液体电解质的电化学窗口、热稳定性。最后,以NaCl包覆的泡沫铜作为电池正极,用玻璃封接的方法组装平板化的试验用Na/CuCl2电池,并测试电池性能。实验结果表明:用离子液体电解质来替代传统的NaAlCl4电解质有着很高的可行性与研究价值,组装的平板Na/CuCl2电池可在175 ℃条件下稳定运行,表现出较好的电化学性能。
Abstract:
With high melting point sodium tetrachloroaluminate(NaAlCl4)as catholyte(157 ℃),traditional sodium metal chloride batteries(ZEBRA)were usually operated at the temperature range of 270 to 350 ℃.In the paper,0.2 mol/L sodium trifluomethanesulfonate(NaCF3SO3)was dissolved in an ionic liquid of 1-ethyl-3-methylimidazolium bistrifluoromethylsulfonyl imide(EMIMTFSI)and examined the resolution as the catholyte in order to lower down the working temperature of ZEBRA batteries to 175 ℃.The thermal stability and electrochemical window of the home made catholyte were tested using thermogravimetry and cyclic voltgrammetry.A planar cell,with Cu as the positive electrode,was built to evaluate the electrochemical performance of this Na/CuCl2 battery.Results showed that the EMIMTFSI based catholyte was a promising candidate to be applied for intermediate temperature(175 ℃)ZEBRA batteries. The planar intermediate Na/CuCl2 battery can be operated at 175 ℃ stably with this ionic liquid catholyte.
