Ngano chete ndiyo inozvitaurira nokukurumidza. Yakazozivikanwa nezvekambani yeAmerica Enevate, iyo yakanga ichigadzira mabhatiri e-lithium-ion ane silicon anodes. Tekinoroji nyowani yakavimbisa kuwedzera simba rekuchengetedza simba uye nekukurumidza kuchaja. Kubva ipapo, tekinoroji yakaramba ichivandudza uye mahombekombe ave kutoonekwa. Iko hakuna anopfuura makore mashanu asara kusati kwaitwa kunoshanda kwemabhatiri matsva.
sei IEEE Spectrum webhusaiti ine chinongedzo cheEnevate, vagadziri vakakura muindasitiri yemotokari, kunyanya Renault, Nissan neMitsubishi, pamwe nevagadziri vebhatiri LG Chem uye Samsung, vakafarira tekinoroji yebhatiri yekambani. Vese vari vatengesi muEnevate. Kuvandudza tekinoroji kwakatanga makore angangoita gumi apfuura. Kana ichionekwa mumotokari, sezvakavimbiswa, muna 10-2024, ipapo nzira kubva purogiramu kusvika pakuitwa kwayo ichava makore gumi nemashanu.
Nenzira, Enevate's Advisory board inosanganisira 2019 Chemistry Award: John Goodenough, akagamuchira mubairo wepamusoro-soro wekubudirira kwake mukuvandudza mabhatiri e-lithium-ion. Akabatanidzwa mukuvandudza tekinoroji yebhatiri yeEnevate nguva refu asati awana mubairo uyu, saka kuEnevate haasi kutamba se "mukuru wemuchato", asi kuenda kubhizinesi. Uye, kutaura chokwadi, mushure mekunge mubairo wapihwa, inopa iyo kambani huremu hwakawanda mumaziso evanoisa mari.
Pfungwa yekuseri kweEnevate ndeyekugadzira anode kunyanya kubva . Silicon inogona kuchengeta maion kurekodha simba rekuchengetedza simba uye kuita nekukurumidza zvakanyanya kupfuura anode akagadzirwa kubva kune zvimwe zvinhu (pamwe kunze kweinodhura graphene). Iyo Enevate lithium-ion bhatiri inochaja inosvika 75% yekugona kwayo mumaminetsi mashanu. Iyo ine zvakare 5% yakawanda simba rekuchengetedza kupfuura yemazuva ano lithium-ion mabhatiri. Iyo kambani inozivisa iyi parameter pa30 Wh/kg. Sezvineiwo, mota yemagetsi inofambiswa neEnevate mabhatiri inogona kufamba 350 km mushure mekuchaja bhatiri kwemaminetsi mashanu.
Chakavanzika cheEnevate bhatiri chiri mune yakakosha anode chimiro. Iyo silicon layer muanode ine ukobvu hwegumi kusvika 10 microns uye ine porous zvisingaite. Izvi zvinowedzera zvese ion kufamba mune anode uye simba rekuchengetedza density. Zvakare, iyo porous dhizaini inomisa maitiro anoparadza musilicon anoitika panguva yekuchaja uye kuburitsa mabhatiri.
Mukuwedzera, iyo silicon layer yeanode inodzivirirwa pamativi ese nechikamu chegraphite. Graphite inodzivirira kukanganisa kusangana kwesilicon ne electrolyte. Chinhu chikuru chakashata cheEnevate mabhatiri kwaive kukurumidza kuparadzwa kwesilicon anode layer. Saka, mushure mekutanga kubhadharisa uye kutenderera kutenderera, bhatiri rakarasikirwa ne7% yehuwandu hwayo. Iyo porous dhizaini yesilicon anode layer yakagadzirirwa kukunda iyi drawback, asi kuti yakawanda sei iyo kambani yakavandudza huwandu hwekuchaja uye kuburitsa madhizaini haina kutaurwa. Ngativimbei kuti kambani inotora yakavimbiswa makore mana kana mashanu kuunza tekinoroji mukugadzirwa kwekutengesa.
