| 摘 要： | 在单电池中用充电一放电循环测试方法研究了不同厚度Nation膜对多硫化钠／溴单电池效率及电池负极液中的多硫（Sx＋1^2-）及硫氢根离子（HS^-）向正极溶液中扩散（即透硫率）的影响。结果表明：随着膜厚度的增加，电池的库仑效率升高，膜的透硫率及电压效率降低。用四丁基溴化胺（TBAB）对Nation112膜进行了初步改性处理，显著提高了电池的库仑效率，减少了膜的透硫率，但由于改性膜电阻的增加，致使电池电压效率下降。

| Abstract: | Effects of Nafion membranes with different thickness on efficiency performance of polysulfide/bromine battery(PSB) and permeating amount of Sx+1 2-and HS-from anolyte to catholyte(i.e.permeating amount of S) were investigated by charge-discharge cycle method using a single PSB cell.The results showed that the coulombic efficiency(CE) of the cell increased with the increase of the thickness of membrane,correspondingly,the permeating amount of S and the voltage efficiency(VE) of the cell decreased.The CE of the cell with Nafion 112 membrane modified by tetrabutyl ammonium bromide(TBAB) was greatly enhanced comparing to that of the cell employing unmodified 112 membrane,correspondingly,the permeating amount of S decreased.The VE of the cell with modified 112 membrane declined,due to the enhanced resistance of the membrane modified by TBAB. |
