Kuyerera kwebhatiri simba rekuchengetedza tekinoroji

Flow bhatiri inowanzova electrochemical simba rekuchengetedza mudziyo. Kuburikidza neiyo oxidation-kudzikisa reaction yemvura inoshanda zvinhu, kutendeuka kwesimba remagetsi uye kemikari simba kunopera, nekudaro kugumisa kuchengetedza uye kuburitswa kwesimba remagetsi. Nekuda kwemabhenefiti ayo akatanhamara senge yakazvimirira simba uye kugona, yakadzika kuchaja uye kudzika kudzika, uye kuchengetedzwa kwakanaka, yave imwe yesarudzo dzakanakisa mumunda wekuchengetedza simba.

Sezvo bhatiri remvura rakagadzirwa muma1970s, rakapfuura nemapurojekiti anopfuura zana, kubva murabhoritari kuenda kukambani, kubva kune prototype kuenda kune yakajairwa chigadzirwa, kubva pakuratidzira kusvika kune kutengeserana kushandiswa, kubva kudiki kusvika kuhombe, kubva kune imwe kuenda kune yepasirese.

Iyo yakaiswa simba revanadium inoyerera bhatiri i35mw, inova ndiyo inonyanya kushandiswa kuyerera bhatiri. Dalian Rongke Energy Storage Technology Co., Ltd. (inozonzi Rongke Energy Storage), inopihwa mari neDalian Institute of Chemical Physics, Chinese Academy of Sciences, yakabatana neDalian Institute of Chemical Physics kupedzisa kugadzikiswa kwenzvimbo uye kwakarongwa kugadzirwa kwe zvinhu zvakakosha zveese-vanadium redox kuyerera mabhatiri. Panguva imwecheteyo, zvigadzirwa zve electrolyte zvinotumirwa kuJapan, South Korea, United States, Germany, United Kingdom nedzimwe nyika. Kusarudzwa kwepamusoro, kusimba kwepamusoro uye kudhura kwakaderera kweiyo isiri-fluorine ion conductive membrane iri nani pane perfluorosulfonic acid ion exchange membranes, uye mutengo unongova 10% yemabhatiri ese vanadium anoyerera, ayo anotyora chaizvo mumutengo webhodhoro reese vanadium kuyerera mabhatiri. .

Kuburikidza nekugadzirisa zvimiro uye nekushandiswa kwezvinhu zvitsva, iyo yekuwedzera inoshanda yazvino density yeiyo-vanadium inoyerera bhatiri reactor yakaderedzwa kubva kune yekutanga 80 mA kuenda kune yepamusoro C/C㎡ 120 mA/㎡ uku uchichengeta basa rimwechete. Mutengo weiyo reactor wakaderedzwa neinenge 30%. Iyo yakajairwa single stack ndeye 32kw, iyo yakatumirwa kuUnited States neGermany. Muna Chivabvu 2013, hombe pasi rose 5 MW/10 MWH vanadium inoyerera bhatiri rekuchengetedza simba system yakabudirira kubatana kune grid paGuodian Longyuan 50mw mhepo yepamhepo. Zvadaro, iyo 3mw / 6mwh mhepo yemagetsi grid-yakabatana simba rekuchengetedza simba, uye Guodian uye simba remhepo 2mw / 4mwh mapurojekiti ekuchengetedza simba akashandiswa muJinzhou, ayo ariwo zviitiko zvakakosha munyika yangu yekuongorora maitiro emabhizimisi ekuchengetedza simba.

Mumwe mutungamiri mumabhatiri ekuyerera kwevanadium ndeye sumitomoelectric yekuJapan. Kambani iyi yakatangazve bhizinesi rayo remabhatiri enhare muna 2010 uye ichapedza 15MW/60MW/hr vanadium bhatiri rekushandisa muna 2015 kuti ribate nepamusoro-soro uye kudzvanywa kwemhando yemagetsi kwakaunzwa nekubatanidzwa kwezvirimwa zvakakura zvezuva muHokkaido. Kuitwa kwakabudirira kwechirongwa ichi kuchave chimwe chiitiko chakakosha mumunda wevanadium kuyerera mabhatiri. Muna 2014, nerutsigiro rweUS Energy and Clean Fund, US UniEnergy Technologies LLC (UET) yakagadzira 3mw/10mw yakazara-kuyerera vanadium bhatiri rekuchengetedza simba system muWashington. UET ichashandisa tekinoroji yayo yakasanganiswa asidhi electrolyte kekutanga kuwedzera simba remagetsi neinosvika 40%, kuwedzera tembiricha yehwindo uye voltage renji yemabhatiri ese vanadium inoyerera, uye kuderedza kupisa kwesimba rekushandisa.

Parizvino, simba resimba uye kuvimbika kwehurongwa hweyakanaka kuyerera lithium mabhatiri, uye kuderedza mari yavo inyaya dzakakosha mukuronga kwekushandisa kwakakura kwemabhatiri ekuyerera kwakanaka. Iyo yakakosha tekinoroji ndeyekugadzira yakakwirira-inoshanda bhatiri zvinhu, optimize bhatiri chimiro dhizaini, uye kuderedza bhatiri mukati kuramba. Munguva pfupi yapfuura, timu yekutsvagisa yaZhang Huamin yakagadzira bhatiri re-vanadium redox inoyerera ine bhatiri rechaji uye simba rekuburitsa simba. Kushanda ikozvino density ndeye 80ma / C square mita, iyo yakasvika 81% uye 93% makore mashoma apfuura, izvo zvinonyatso ratidza hupamhi hwayo. Nzvimbo uye tarisiro.
