摘要
电解液的优化,对水系锌离子电池性能的提升有很大的影响。在常见的水系锌离子电池硫酸锌电解液中添加不同质量浓度的羧甲基纤维素钠(CMC-Na)、十二烷基苯磺酸钠(SDBS)和十二烷基三甲基溴化铵(DTAB),以V_(2)O_(5)为正极,锌为负极组成电池,通过研究常见物理性能和电化学性能发现,添加表面活性剂可以有效提高水系锌离子电池的性能,在电流密度1A·g^(-1)循环200圈后,各添加体系均表现出良好的性能。
The optimization of electrolyte has a great influence on the performance of aqueous zinc ion battery.Sodium carboxymethylcellulose(CMC-Na),sodium dodecylbenzene sulfonate(SDBS)and dodecyltrimethylammonium bromide(DTAB)with different mass concentrations were added to the zinc sulfate electrolyte of common aqueous zinc ion batteries.The battery was composed of vanadium pentoxide as the positive electrode and zinc as the negative electrode.Through the study of common physical and electrochemical properties,The addition of zinc ion surfactant can effectively improve the performance of battery after 200 cycles of current density 1A·g^(-1),each addition system showed good performance.
