Ubuchwepheshe bokugcina amandla ebhethri agelezayo

Ibhethri eligelezayo ngokuvamile liyidivayisi yokugcina amandla e-electrochemical. Ngokusabela kokunciphisa i-oxidation yezinto ezisebenzayo eziwuketshezi, ukuguqulwa kwamandla kagesi namandla amakhemikhali kuyaphela, ngaleyo ndlela kuqedwe ukugcinwa nokukhululwa kwamandla kagesi. Ngenxa yezinzuzo zayo ezivelele njengamandla azimele namandla, ukushaja okujulile nokujula kokukhishwa, nokuphepha okuhle, isibe yinye yezinketho ezinhle kakhulu emkhakheni wokugcinwa kwamandla.

Kusukela ibhethri eliwuketshezi lasungulwa ngeminyaka yawo-1970s, selidlule kumaphrojekthi angaphezu kuka-100, lisuka elabhorethri liye enkampanini, lisuka ku-prototype liye emkhiqizweni ojwayelekile, lisuka ekubonisweni liye ekusetshenzisweni kwezentengiselwano, lisuka kwabancane kuye kwabalikhulu, ukusuka kokukodwa kuya kulo lonke izwe.

Umthamo ofakiwe webhethri le-vanadium flow ngu-35mw, okuyibhethri eligeleza elisetshenziswa kakhulu njengamanje. I-Dalian Rongke Energy Storage Technology Co., Ltd. (kamuva ebizwa ngokuthi i-Rongke Energy Storage), exhaswe yi-Dalian Institute of Chemical Physics, i-Chinese Academy of Sciences, ibambisane ne-Dalian Institute of Chemical Physics ukuqedela ukwenziwa kwasendaweni kanye nokukhiqizwa okuhleliwe kwe izinto ezibalulekile zawo wonke amabhethri e-vanadium redox flow. Ngesikhathi esifanayo, imikhiqizo ye-electrolyte ithunyelwa eJapane, eNingizimu Korea, e-United States, eJalimane, e-United Kingdom nakwamanye amazwe. Ukukhetha okuphezulu, ukuqina okuphezulu kanye nezindleko eziphansi ze-non-fluorine ion conductive membrane zingcono kune-perfluorosulfonic acid ion exchange membranes, futhi intengo ingu-10% kuphela wawo wonke amabhethri okugeleza kwe-vanadium, agqekeza ngempela ibhodlela lezindleko zawo wonke amabhethri okugeleza kwe-vanadium. .

Ngokwenza kahle kwesakhiwo kanye nokusetshenziswa kwezinto ezintsha, ukuminyana okwengeziwe kwamanje kokusebenza kwe-all-vanadium flow battery rector kuncishisiwe kusuka ku-80 mA yasekuqaleni kuya ku-C/C㎡ 120 mA/㎡ ethuthukisiwe kuyilapho kugcinwa umsebenzi ofanayo. Izindleko ze-reactor zehliswe cishe ngama-30%. Isitaki esisodwa esijwayelekile singu-32kw, esithunyelwe e-United States naseJalimane. NgoMeyi 2013, uhlelo lokugcina amandla ebhethri eligeleza i-5 MW/10 MWH elikhulu kunawo wonke emhlabeni laxhunywa ngempumelelo kugridi epulazini lomoya laseGuodian Longyuan 50mw. Kamuva, iphrojekthi yokugcina amandla kagesi omoya engu-3mw/6mwh exhunywe kugridi yamandla omoya, kanye namaphrojekthi okugcina amandla kagesi e-Guodian namandla omoya angu-2mw/4mwh asetshenziselwe e-Jinzhou, okuyizimo ezibalulekile futhi ekuhloleni kwezwe lami amamodeli ebhizinisi okugcina amandla.

Omunye umholi kumabhethri okugeleza kwe-vanadium yi-sumitomoelectric yaseJapan. Inkampani yaqala kabusha ibhizinisi layo lamabhethri ahambahambayo ngo-2010 futhi izoqedela imboni yebhethri ye-vanadium engu-15MW/60MW/hr ngo-2015 ukuze ibhekane nomthwalo omkhulu kanye nokucindezela kwekhwalithi yamandla okulethwe ukuhlanganiswa kwezitshalo zelanga ezinkulu eHokkaido. Ukuqaliswa ngempumelelo kwalo mklamo kuzoba esinye isenzakalo esibalulekile emkhakheni wamabhethri agelezayo e-vanadium. Ngo-2014, ngokwesekwa yi-US Energy and Clean Fund, i-US UniEnergy Technologies LLC (UET) yasungula isistimu yokugcina amandla ebhethri ye-vanadium engu-3mw/10mw egeleza ngokugcwele e-Washington. I-UET izosebenzisa ubuchwepheshe bayo be-acid exubile ye-electrolyte okokuqala ngqa ukukhulisa ukuminyana kwamandla cishe ngama-40%, yandise iwindi lokushisa kanye nobubanzi be-voltage yawo wonke amabhethri okugeleza kwe-vanadium, futhi yehlise ukusetshenziswa kwamandla okulawula ukushisa.

Njengamanje, amandla wamandla kanye nokuthembeka kwesistimu yokugeleza okuhle kwamabhethri e-lithium, nokunciphisa izindleko zabo yizindaba ezibalulekile ekuhleleni ukusetshenziswa okubanzi kwamabhethri okugeleza okuhle. Ubuchwepheshe obubalulekile wukuthuthukisa izinto zebhethri ezisebenza kahle kakhulu, ukuthuthukisa idizayini yesakhiwo sebhethri, nokunciphisa ukumelana kwangaphakathi kwebhethri. Muva nje, ithimba locwaningo lika-Zhang Huamin lenze ibhethri eligelezayo le-all-vanadium redox elinokushajwa kwebhethri elilodwa namandla okukhipha amandla. Ukuminyana okusebenzayo njengamanje kungu-80ma/C square meter, okufinyelele ku-81% no-93% eminyakeni embalwa edlule, okufakazela ngokugcwele ububanzi bayo. Isikhala namathemba.
