Zofunikira zitatu zazikulu za batri yosungira mphamvu, chitetezo ndicho chofunikira kwambiri
Kusungira mphamvu zamagetsi kumaonedwa kuti ndi njira yayikulu yosungira mphamvu m'tsogolo, batri ndi PCS ndiye chinthu chofunikira kwambiri komanso chopinga mu unyolo wamakampani, kufunikira kwakukulu kuli mu chitetezo champhamvu, moyo wautali komanso mtengo wotsika. Pakati pawo, chitetezo ndiye chinsinsi. Akatswiri ena amakampani adati, tsopano chomera chamagetsi chosungira mphamvu zamagetsi chikukula mwachangu, koma vuto lachitetezo ndi vuto la chitukuko chake chachikulu, chomera chamagetsi chosungira mphamvu ku Beijing ndi polojekiti yosungira mphamvu ku Tesla Australia ya kuphulika kwa bomba komanso kwa makampani osungira mphamvu apereka alamu.
Pachifukwa ichi, Malingaliro Otsogolera pa Kufulumizitsa Kukula kwa Malo Osungiramo Mphamvu Zatsopano akuika patsogolo kukhazikitsidwa kwa miyezo ya ukadaulo wachitetezo ndi njira yoyendetsera, kulimbitsa kasamalidwe ka chitetezo cha moto, kutsatira mosamalitsa mfundo yachitetezo monga mfundo yoyambira; pachitetezo chapamwamba, mtengo wotsika, kudalirika kwambiri, moyo wautali ndi zina mwazinthu zina za kupita patsogolo kwakutali; kulimbitsa chitetezo cha kafukufuku waukadaulo wosungira mphamvu zamagetsi ndi zina zotero. National Development and Reform Commission, National Energy Board kuti ikonze kulemba "Njira Zapakati Zoyendetsera Chitetezo cha Malo Osungira Mphamvu Zamagetsi (Draft)", yakhalanso pa Ogasiti 24 kwa anthu ammudzi kuti akambirane, kuti alimbikitse kasamalidwe ka chitetezo chosungira mphamvu.
Chitetezo chapamwamba, moyo wautali, mtengo wa batri ya nickel-metal hydride
Deta ya China Battery Industry Association ikuwonetsa kuti nickel-metal hydride yamagetsi ndi yotetezeka kwambiri, imakhala ndi moyo wautali, ma electrode ake abwino opangidwa ndi ma nickel sphere, zinthu zogwira ntchito za electrode yoyipa zimathandizidwa ndi alloy yosungira hydrogen, ndi ya chinthu chokhazikika, electrolyte yamadzi ili ndi mphamvu zabwino zoletsa moto, sizimaphulika ndikuwotcha ngozi, kuchuluka kwa mphamvu ya monomer ya batri mpaka 140wh/kg; moyo wa batri mpaka 3,000, kuyatsa pang'ono ndi kutulutsa mpweya mpaka nthawi 10,000 kapena kuposerapo; ingagwiritsidwe ntchito nthawi zoposa 10,000; ingagwiritsidwe ntchito nthawi zoposa 10,000. Nthawi zoposa 10,000; imatha kusunga chiwongola dzanja chambiri cha kuchaja ndi kutulutsa mpweya mu -40°C ~ 60°C. Malonda apadziko lonse a magalimoto a Toyota HEV afika oposa 18 miliyoni, ndipo ali ndi mabatire ambiri a nickel-metal hydride, sipanakhalepo vuto lililonse la ngozi zoyaka mabatire, chitetezo cha batri chatsimikizika mokwanira.
Komanso, kuyatsa ndi kutulutsa batire ndiko kusintha kwa mphamvu zamagetsi ndi mphamvu zamagetsi, kutentha kumakhudza kwambiri momwe mankhwala amachitira. Malo osungira mphamvu zamagetsi nthawi zambiri amakhala panja, mitundu yambiri ya mabatire imakhudzidwa ndi chilengedwe ndi kutentha, zomwe zimalepheretsa malo osungira mphamvu ndikufooketsa ntchito yosungira mphamvu. Mabatire a nickel-metal hydride mu kutentha kochepa kwambiri komanso kutentha kwambiri amalipiritsa bwino komanso amalipiritsa bwino, kotero kuti malo osungira mphamvu amalipiritsa mosavuta, mosavuta, komanso magwiridwe antchito abwino, omwe akhala nawo mu mpikisano wa njira zosiyanasiyana zaukadaulo wa batire "kuphatikiza mfundo".
Ndipotu, mabatire a nickel-metal hydride pamsika wosungira mphamvu akhala chitsanzo. Mu 2020, kampani yosungira mphamvu ya nickel-metal hydride Nilar ndi European Investment Bank idayika ndalama zokwana ma euro 47 miliyoni. Zikumveka kuti Nilar ikuyang'ana kwambiri pakuphatikiza mphamvu zobwezerezedwanso ndi kusungira, magetsi okhazikika komanso kugwiritsa ntchito magetsi amagetsi, ndalamazo ndi zolimbikitsa kampaniyo idzaphatikizidwa mu batire ya nyumba, zamalonda ndi mafakitale komanso makina amsika wa gridi kapena zomangamanga. Malinga ndi Frontiers in Polymer Science, gulu la Pulofesa Yi Cui ku Stanford University lapanga batire ya nickel-metal hydride (Ni-MH) yamagetsi akuluakulu obwezerezedwanso ndi kusungira, ndi ubwino wa moyo wautali kwambiri, palibe chiopsezo cha moto kapena kuthawa kwa kutentha, palibe chifukwa chokonza nthawi zonse, khalidwe labwino lotsika kutentha, komanso mtengo wotsika. Gulu la Cui lidzamanga chipangizo choyesera chokhala ndi mphamvu yosungira ma megawatts awiri mu 2021, ndipo likukonzekera kukulitsa mphamvu yake kufika nthawi 20 pofika chaka cha 2022.
