近(jin)日(ri)，中國(guo)科學院大連化學物理研究所儲(chu)能技(ji)術(shu)研(yan)究部（DNL17）李先(xian)鋒研(yan)究員和袁治(zhi)章研(yan)究員團隊開發(fa)出面(mian)向用戶側的30kWh鋅(xin)溴液流電(dian)池系(xi)(xi)統(tong)。該系(xi)(xi)統(tong)由(you)電(dian)解液循環系(xi)(xi)統(tong)、2個(ge)獨(du)立的電(dian)堆、以及(ji)與其配套的電(dian)力控制模塊組成，設(she)計容(rong)量為(wei)30kWh。經(jing)測試(shi)，該系(xi)(xi)統(tong)在額(e)定10kW功率下放(fang)電(dian)時，放(fang)電(dian)電(dian)量為(wei)30kWh。該系(xi)(xi)統(tong)可應用(yong)于分布式能(neng)源及(ji)家用(yong)儲(chu)能(neng)等領域。

鋅溴(xiu)液(ye)流(liu)(liu)電(dian)(dian)池(chi)(chi)具(ju)有成本低、開路電(dian)(dian)壓高(gao)(gao)（1.82V）、能(neng)(neng)(neng)量(liang)密(mi)(mi)(mi)度(du)高(gao)(gao)（>190Wh/L，基(ji)(ji)于(yu)2mol/L活性物(wu)質）等優勢，非常適合在分布式儲(chu)(chu)能(neng)(neng)(neng)及戶(hu)用(yong)儲(chu)(chu)能(neng)(neng)(neng)等領(ling)域應用(yong)。近年(nian)來，中科院大連化物(wu)所(suo)儲(chu)(chu)能(neng)(neng)(neng)技術(shu)(shu)研(yan)究(jiu)部堅(jian)持(chi)(chi)基(ji)(ji)礎(chu)研(yan)究(jiu)與(yu)應用(yong)研(yan)究(jiu)并重(zhong)，以(yi)鋅溴(xiu)液(ye)流(liu)(liu)電(dian)(dian)池(chi)(chi)關鍵材料的(de)(de)(de)設(she)計(ji)、開發、制備為主線(xian)，解決了(le)鋅溴(xiu)液(ye)流(liu)(liu)電(dian)(dian)池(chi)(chi)鋅枝晶（Energy Environ. Sci.，2021；Adv. Mater.，2020）、面容量(liang)受(shou)限（Science Bulletin，2021）、溴(xiu)滲透(tou)（Adv. Mater.，2020；Adv. Funct. Mater.，2021）、功率(lv)密(mi)(mi)(mi)度(du)偏(pian)低（Adv. Funct. Mater.，2021；Adv. Mater.，2019）等關鍵科學與(yu)技術(shu)(shu)問題，將(jiang)鋅溴(xiu)液(ye)流(liu)(liu)電(dian)(dian)池(chi)(chi)電(dian)(dian)堆面容量(liang)提高(gao)(gao)至140mAh/cm2，從而大幅度(du)提高(gao)(gao)了(le)電(dian)(dian)池(chi)(chi)能(neng)(neng)(neng)量(liang)密(mi)(mi)(mi)度(du)。同(tong)時，團隊以(yi)電(dian)(dian)堆結(jie)構(gou)設(she)計(ji)與(yu)系(xi)統(tong)控制策略開發為兩(liang)翼，突破了(le)高(gao)(gao)功率(lv)密(mi)(mi)(mi)度(du)、高(gao)(gao)可靠性電(dian)(dian)堆的(de)(de)(de)結(jie)構(gou)設(she)計(ji)與(yu)組(zu)裝技術(shu)(shu)，開發出高(gao)(gao)能(neng)(neng)(neng)量(liang)密(mi)(mi)(mi)度(du)、低成本用(yong)戶(hu)側鋅基(ji)(ji)液(ye)流(liu)(liu)電(dian)(dian)池(chi)(chi)儲(chu)(chu)能(neng)(neng)(neng)系(xi)統(tong)。該(gai)系(xi)統(tong)的(de)(de)(de)成功開發，將(jiang)進(jin)一步(bu)推(tui)動用(yong)戶(hu)側新型液(ye)流(liu)(liu)電(dian)(dian)池(chi)(chi)的(de)(de)(de)發展(zhan)與(yu)產(chan)業化應用(yong)，對(dui)于(yu)推(tui)動液(ye)流(liu)(liu)電(dian)(dian)池(chi)(chi)可持(chi)(chi)續發展(zhan)具(ju)有重(zhong)要意義(yi)。
