Theknoloji ea ho boloka matla a betri e phallang

Betri e phallang hangata ke sesebelisoa sa ho boloka matla a electrochemical. Ka karabelo ea phokotso ea oxidation ea lisebelisoa tse sebetsang tsa mokelikeli, phetoho ea matla a motlakase le matla a lik’hemik’hale e felile, ka hona ho felisa polokelo le ho lokolloa ha matla a motlakase. Ka lebaka la melemo ea eona e ikhethang e kang matla a ikemetseng le bokhoni, tefiso e tebileng le botebo ba ho ntša metsi, le polokeho e ntle, e fetohile e ‘ngoe ea likhetho tse ntle ka ho fetisisa tšimong ea polokelo ea matla.

Ho tloha ha betri ea mokelikeli e qapiloe lilemong tsa bo-1970, e fetile merero e fetang 100, ho tloha laboratoring ho ea ho khampani, ho tloha ho prototype ho ea ho sehlahisoa se tloaelehileng, ho tloha pontšong ho ea ts’ebetsong ea khoebo, ho tloha ho tse nyenyane ho ea ho tse kholo, ho tloha ho e le ‘ngoe ho ea ho bokahohle.

Bokhoni bo kentsoeng ba betri ea phallo ea vanadium ke 35mw, eo hajoale e leng eona betri ea phallo e sebelisoang haholo. Dalian Rongke Energy Storage Technology Co., Ltd. (eo ka mor’a moo e bitsoang Rongke Energy Storage), e tšehelitsoeng ka lichelete ke Dalian Institute of Chemical Physics, Chinese Academy of Sciences, e sebelisana le Dalian Institute of Chemical Physics ho phethela tlhahiso ea lehae le tlhahiso e reriloeng ea lisebelisoa tsa bohlokoa bakeng sa libeteri tsohle tsa banadium redox flow. Ka nako e ts’oanang, lihlahisoa tsa electrolyte li romeloa Japane, Korea Boroa, United States, Jeremane, United Kingdom le linaheng tse ling. Khetho e phahameng, nako e telele ea nako e telele le litšenyehelo tse tlase tsa “non-fluorine ion conductive membrane” li molemo ho feta perfluorosulfonic acid ion exchange membranes, ‘me theko ke 10% feela ea li-betri tsohle tsa vanadium, tse phunyeletsang litšenyehelo tsa libeteri tsohle tsa vanadium. .

Ka ntlafatso ea meralo le ts’ebeliso ea lisebelisoa tse ncha, sekhahla se eketsehileng sa ts’ebetso ea betri ea “vanadium flow” e fokotsehile ho tloha ho 80 mA ea mantlha ho isa ho C/C㎡ 120 mA/㎡ e tsoetseng pele ha e ntse e boloka ts’ebetso e ts’oanang. Litsenyehelo tsa motlakase li fokotsehile ka hoo e ka bang 30%. Sekepe se le seng se tloaelehileng ke 32kw, se rometsoeng United States le Jeremane. Ka Motsheanong 2013, sistimi e kgolo ka ho fetisisa lefatsheng ya 5 MW/10 MWH vanadium flow betri ya ho boloka eneji e ile ya hokelwa ka katleho polasing ya moya ya Guodian Longyuan 50mw. Ka mor’a moo, morero oa polokelo ea matla o hoketsoeng ke marang-rang a 3mw/6mwh, le merero ea polokelo ea matla ea 2mw/4mwh ea matla a moea a XNUMXmw/XNUMXmwh e kentsoe tšebetsong Jinzhou, tseo le tsona e leng maemo a bohlokoa patlisisong ea naha ea heso ea mekhoa ea khoebo ea polokelo ea matla.

Moetapele e mong oa libeteri tsa phallo ea vanadium ke sumitomoelectric ea Japane. Khamphani e ile ea qala bocha khoebo ea eona ea libeteri tse tsamaeang ka 2010 ‘me e tla phethela polante ea 15MW/60MW/hr vanadium ea betri e tsamaeang ka hora ka 2015 ho sebetsana le boima ba tlhōrō le khatello ea boleng ba matla e tlisitsoeng ke ho kopanngoa ha limela tse kholo tsa letsatsi Hokkaido. Ho kenngwa tshebetsong ka katleho ha projeke ena e tla ba sehlohlolo se seng lebaleng la dibetri tsa phallo ya vanadium. Ka 2014, ka tšehetso ea Letlole la Matla le Hloekileng la US, US UniEnergy Technologies LLC (UET) e thehile sistimi ea ho boloka matla a betri ea vanadium ea 3mw/10mw e phallang ka botlalo Washington. UET e tla sebelisa thekenoloji ea eona e tsoakiloeng ea elektrolyte ea acid e le lekhetlo la pele ho eketsa boima ba matla ka hoo e ka bang 40%, ho atolosa fensetere ea mocheso le mefuta e mengata ea li-voltage tsa libeteri tsohle tsa phallo ea vanadium, le ho fokotsa tšebeliso ea matla a ho laola mocheso.

Hona joale, matla a matla le ts’epo ea tsamaiso ea li-betri tsa lithium tse phallang hantle, le ho fokotsa litšenyehelo tsa bona ke litaba tsa bohlokoa ho rala tšebeliso e pharaletseng ea libethe tse ntle tsa phallo. Theknoloji ea bohlokoa ke ho nts’etsapele lisebelisoa tsa betri tse sebetsang hantle, ho ntlafatsa moralo oa sebopeho sa betri, le ho fokotsa khanyetso ea kahare ea betri. Haufinyane tjena, sehlopha sa lipatlisiso sa Zhang Huamin se thehile betri ea “anadium redox flow” e nang le betri e le ‘ngoe le matla a ho ntša matla. Boima ba hona joale ba ho sebetsa ke 80ma / C square meter, e fihlileng ho 81% le 93% lilemong tse ‘maloa tse fetileng, e leng se pakang ka botlalo bophara ba eona. Sebaka le litebello.
