| 英文摘要 | the first use of nickel foam (nf) as electrocatalytic negative electrode in a polysulfide/bromine battery (psb) is described. the performance of a psb employing nf and polyacrylonitrile (pan)-based carbon felt (cf) as negative and positive electrode materials, respectively, was evaluated by constant current charge-discharge tests in a single cell. charge/discharge curves of the cell, positive and negative electrodes show that the rapid fall in cell voltage is due to the drop of positive potential caused by depletion of br-2 dissolved in the catholyte at the end of discharge. cell voltage efficiency was limited by the relatively high internal ohmic resistance drop (ir drop). polarization curves indicated that both nf and cf have excellent catalytic activity for the positive and negative redox reactions of psb. the average energy efficiency of the single cell designed in this work could be as high as 77.2% at 40 ma cm(-2) during 48 charge-discharge cycles.
