Zvitatu zvikuru zvinodikanwa zvesimba rekuchengetedza bhatiri, chengetedzo ndiyo inonyanya kukosha
Electrochemical simba rekuchengetedza inoonekwa seyakanyanya nzira yekuchengetedza simba mune ramangwana simba system, bhatiri uye PCS ndiyo yakanyanya kukosha uye zvipingamupinyi mumaketani eindasitiri, kudiwa kwepakati kuri mukuchengetedzeka kwakanyanya, hupenyu hurefu uye mutengo wakaderera. Pakati pazvo, kuchengeteka ndicho chinokosha. Dzimwe nyanzvi dzeindasitiri dzakati, ikozvino magetsi emagetsi ekuchengetedza magetsi ari kukura nekukurumidza, asi nyaya yekuchengetedza ndiyo bhodhoro rekukura kwayo kukuru, Beijing simba rekuchengetedza magetsi chirimwa uye Tesla Australia purojekiti yekuchengetedza simba rekuputika zvakare yeindasitiri yekuchengetedza simba yakaridza alarm.
Kuti izvi zviitike, Maonero Anotungamirira paKukurumidzira Kuvandudzwa kweNew Energy Storage inoisa mberi kugadzwa kwekuchengetedzwa kwekombiyuta mitemo uye hurongwa hwehutungamiri, kusimbisa hutungamiri hwekuchengetedza moto, kunyatsoteerera mutsara wekuchengetedzwa kwepamusoro senheyo inokosha; mukuchengetedzwa kwepamusoro, mutengo wakaderera, kuvimbika kwakanyanya, hupenyu hurefu uye zvimwe zvikamu zvekufambira mberi kwenguva refu; kusimbisa kuchengetedzwa kwe electrochemical simba rekuchengetedza tekinoroji yekutsvaga uye zvichingodaro. National Development and Reform Commission, National Energy Board kuronga kunyorwa kwe "Interm Measures for the Safe Management of Electrochemical Energy Storage Stations (Draft)", yave iriwo musi waAugust 24th kunharaunda yekubvunzurudza kwevanhu, kusimbisa hutungamiri hwekuchengetedzwa kwekuchengetedza simba.
Kuchengetedzeka kwepamusoro, hupenyu hurefu, nickel-metal hydride bhatiri kukosha kwakakwirira
China Battery Industry Association data inoratidza kuti nickel-metal hydride yemagetsi yakachengeteka, hupenyu hurefu hwekutenderera, electrode yayo yakanaka yakagadzirwa nenickel spheres, iyo negative electrode inoshanda zvinhu inotsigirwa nehydrogen storage alloy, ndeyezvinhu zvakadzikama, mvura electrolyte ine yakanaka inodzoreredza zvivakwa, haizoputika nekupisa mutsaona inopisa 140 kutenderera hupenyu hwekusvika ku3,000, kudzika kuchaja uye kuburitsa nyika kutenderera kusvika ku10,000 nguva kana kupfuura; inogona kushandiswa kweanopfuura 10,000 nguva; inogona kushandiswa kweanopfuura 10,000 nguva. Kupfuura 10,000 nguva; inogona kuchengetedza chiyero chepamusoro chekuchaja uye kuburitsa mu -40 ° C ~ 60 ° C nharaunda. Toyota HEV mota yekutengesa kwepasirese yasvika kupfuura mamirioni gumi nemasere, uye yakashongedzerwa zvakanyanya nickel-metal hydride mabhatiri, hapana kana imwe nyaya yetsaona yekupisa kwebhatiri, kuchengetedzwa kwebhatiri kwakanyatso kusimbiswa.
Uyezve, kuchaja uye kuburitsa bhatiri ndiko kushandurwa kwesimba remakemikari uye simba remagetsi, tembiricha ine simba guru pakuita kwemakemikari. Zviteshi zvemagetsi ekuchengetedza magetsi zvakanyanya kunze, marudzi mazhinji emabhatiri anokanganisa nharaunda uye tembiricha, kudzikisira nzvimbo yezviteshi zvemagetsi uye kunetesa basa rekuchengetedza simba. Nickel-metal hydride mabhatiri mune yakadzika kwazvo tembiricha uye yakanyanya tembiricha yakanakisa kuchaja uye kuburitsa kunyatsoita, kuitira kuti simba rekuchengetedza magetsi chiteshi saiti inoshanduka, iri nyore, iri nani kuita kwese kuita, kwave kutora chikamu mumakwikwi eakasiyana mabhatiri tekinoroji nzira "plus point".
Muchokwadi, nickel-metal hydride mabhatiri mumusika wekuchengetedza simba application yanga iri muenzaniso. 2020, nickel-metal hydride bhatiri simba rekuchengetedza kambani Nilar neEuropean Investment Bank 47 mamirioni ekudyara. Zvinonzwisiswa kuti Nilar iri kutarisa kubatanidzwa kwemagetsi ekugadzira magetsi uye kuchengetedza, simba rekumira uye magetsi emagetsi ekuchaja zvikumbiro, mari yacho ndeyekusimudzira kambani ichabatanidzwa mubhatiri rekugara, kutengeserana uye maindasitiri uye grid-scale kana masisitimu emusika. Sekureva kweFrontiers muPolymer Science, timu yaProfessor Yi Cui paStanford University yakagadzira nickel-metal hydride (Ni-MH) bhatiri yehukuru-hukuru hunogona kudzokororwazve uye kuchengetedza zvikumbiro, zvine zvakanakira hupenyu hwesevhisi yehurefu-refu, hapana njodzi yemoto kana kupisa kunotiza, hapana chikonzero chekugara uchigadzirisa, yakanaka yakaderera-yekupisa maitiro, uye yakaderera-yekupisa maitiro. Chikwata chaCui chichavaka chivako chekutyaira chine simba rekuchengetedza 2 megawatts muna 2021, uye inoronga kuwedzera huwandu hwayo kusvika ka20 huwandu uhu panosvika 2022.
