Zvinhu zvitatu zvikuru zvinodiwa pakuchengetedza simba remagetsi, kuchengetedzeka ndiko kwakakosha zvikuru
Kuchengetedzwa kwesimba remagetsi kunoonekwa senzira huru yekuchengetedza simba mune ramangwana, bhatiri uye PCS ndiyo inonyanya kukosha uye zvipingamupinyi muindasitiri, kudiwa kukuru kuri mukuchengetedzwa kwakanyanya, hupenyu hurefu uye mutengo wakaderera. Pakati pavo, kuchengetedzeka ndiko kiyi. Dzimwe nyanzvi dzeindasitiri dzakati, ikozvino chiteshi chemagetsi chemagetsi chiri kukura nekukurumidza, asi nyaya yekuchengetedza idambudziko rekuvandudzwa kwaro kukuru, chiteshi chemagetsi cheBeijing chekuchengetedza simba uye chirongwa chekuchengetedza simba cheTesla Australia chekuputika kwacho chakaridza alarm.
Nekuda kweizvi, Guiding Opinions on Accelerating the Development of New Energy Storage inosimudzira kugadzwa kwemitemo yetekinoroji yekuchengetedza uye sisitimu yekutarisira, kusimbisa manejimendi yekuchengetedza moto, kutevedzera zvakanyanya nhungamiro yekuchengetedza senheyo huru; mukuchengetedza kwakanyanya, mutengo wakaderera, kuvimbika kwakanyanya, hupenyu hurefu nezvimwe zvinhu zvekufambira mberi kwenguva refu; kusimbisa kuchengetedzeka kwekutsvaga tekinoroji yekuchengetedza simba remagetsi nezvimwe zvakadaro. National Development and Reform Commission, National Energy Board kuronga kunyorwa kwe "Interim Measures for the Safe Management of Electrochemical Energy Storage Stations (Draft)", yavewo nemusi wa24 Nyamavhuvhu kunharaunda kuti ikurukure neveruzhinji, kusimbisa manejimendi yekuchengetedza kuchengetedza simba.
Kuchengetedzeka kwakanyanya, hupenyu hurefu, kukosha kwebhatiri re nickel-metal hydride
Data reChina Battery Industry Association rinoratidza kuti nickel-metal hydride yemagetsi yakachengeteka zvakanyanya, hupenyu hwenguva refu, electrode yayo yakanaka yakagadzirwa ne nickel spheres, chinhu chinoshanda che electrode chisina kunaka chinotsigirwa ne hydrogen storage alloy, ndechechinhu chakagadzikana, electrolyte yemvura ine hunhu hwakanaka hwemoto unodzivirira moto, haizoputike kana kupisa tsaona, huwandu hwesimba remonomer yebhatiri hunosvika 140wh/kg; hupenyu hwenguva inosvika 3,000, kushaikwa kwekuchaja nekuburitsa shallow state cycle hunosvika 10,000 kana kupfuura; inogona kushandiswa kanopfuura 10,000; inogona kushandiswa kanopfuura 10,000. Kanopfuura 10,000; inogona kuchengetedza mwero wepamusoro wekuchaja nekuburitsa mu -40°C ~ 60°C nharaunda. Kutengeswa kwemotokari dzeToyota HEV pasi rose kwasvika anopfuura mamiriyoni gumi nemasere, uye kwakashongedzwa zvakanyanya nemabhatiri e nickel-metal hydride, hapana kana imwe nyaya yetsaona dzekupisa mabhatiri, kuchengetedzeka kwakanyanya kwebhatiri kwakasimbiswa zvizere.
Uyezve, kuchaja nekuburitsa mabhatiri ndiko kushandurwa kwesimba remakemikari nesimba remagetsi, tembiricha ine simba guru pakuita kwemakemikari. Nzvimbo dzemagetsi dzekuchengetera simba dziri kunze, mhando zhinji dzemabhatiri dzinokanganiswa nemamiriro ekunze netembiricha, zvichideredza nzvimbo yenzvimbo dzemagetsi uye zvichideredza basa renzvimbo dzemagetsi. Mabhatiri ehydride enickel-metal ari mutembiricha yakaderera uye tembiricha yepamusoro anochaja zvakanaka uye anoburitsa zvakanaka, kuitira kuti nzvimbo yenzvimbo yemagetsi yekuchengetera simba ive yakachinjika, iri nyore, uye iri nani pakuita kwayo, iyo yave kutora chikamu mumakwikwi enzira dzakasiyana dzehunyanzvi hwebhatiri "plus points".
Kutaura zvazviri, mabhatiri e-nickel-metal hydride mukushandiswa kwemusika wekuchengetedza simba ave muenzaniso. 2020, kambani yekuchengetedza simba remabhatiri e-nickel-metal hydride Nilar neEuropean Investment Bank yakaisa mari inosvika mamiriyoni makumi mana nemanomwe emaeuro. Zvinonzwisisika kuti Nilar iri kutarisa pakubatanidzwa kwesimba remagetsi rinodzokororwa uye kuchengetwa, simba rinomira uye mashandisirwo ekuchaja mota dzemagetsi, mari yacho ndeyekusimudzira kambani iyi kuti isanganiswe mubhatiri rekugara, rekutengeserana uye remaindasitiri uye masisitimu emusika wegrid-scale kana zvivakwa. Sekureva kweFrontiers in Polymer Science, timu yaProfessor Yi Cui kuStanford University yakagadzira bhatiri re-nickel-metal hydride (Ni-MH) rekushandisa simba guru rinodzokororwa uye kuchengetedza, nezvakanaka zvehupenyu hwebasa hwakareba, pasina njodzi yemoto kana kupisa, hapana chikonzero chekugadzirisa nguva dzose, maitiro akanaka ekupisa kwakaderera, uye mutengo wakaderera. Chikwata chaCui chichavaka unit yekuedza ine kugona kwekuchengetedza kwe2 megawatts muna 2021, uye inoronga kuwedzera kugona kwayo kusvika ka20 kacho panosvika 2022.
