U-Hitachi Zosen useqalile ukuthumela amasampula ebhethri ye-lithium-ion yokuqala eqinile embonini anama-electrode aqukethe i-sulfate. I-electrolyte kumabhethri e-AS-LiB (ibhethri ye-lithium-ion eliqinile) isesimweni esiqinile, futhi ayikho esimweni esiwuketshezi noma esifana nejeli, njengamabhethri e-lithium-ion avamile, anquma inani lezici ezibalulekile nezihlukile. yomkhiqizo omusha.
Ngakho-ke, i-electrolyte eqinile kumabhethri e-AS-LiB ayishi, ayihwamuki futhi ayijikijeli (ungajiyi) ibe emazingeni okushisa aphansi kakhulu. Izinga lokushisa elimenyeziwe lokusebenza lamabhethri e-AS-LiB lisuka ku-β40 Β°C ukuya ku-120 Β°C. Ngesikhathi esifanayo, imingcele yokusebenza yamabhethri ayishintshi kakhulu kulo lonke uhla. Ukungabi bikho kwezinto eziguquguqukayo kuvumela amabhethri ukuthi asebenze ku-vacuum. Imizimba yabo ngeke ivuvuke lapho besebenza. Futhi lokhu akusho ukuthi isishayo sebhethri ye-lithium-ion - ingozi yomlilo nokuqhuma - akusongeli lesi sigaba samabhethri.
Uma kucatshangelwa izakhiwo ezisohlwini, amabhethri e-AS-LiB kulindeleke ukuthi asetshenziswe kumkhumbi-mkhathi, izinto zezokwelapha kanye nemishini yezimboni. Ngokuzayo, u-Hitachi Zosen ulindele ukukhiqiza amabhethri e-lithium-ion wesimo esiqinile ukuze agcine amandla amile, amanethiwekhi okusabalalisa nezimoto zikagesi.
Ngeshwa, uhlamvu lwemali ngalunye lunobubi. Endabeni yamabhethri e-Hitachi AS-LiB, lawa amandla aphansi okugcina amandla kanye nesilinganiso esigciniwe samandla nesisindo. Le nkampani ayizange icacise lezi zinhlaka, kodwa uma kubhekwa isampula eyethulwe - ibhethri elinezinhlangothi ezingu-52 Γ 65,5 Γ 2,7 mm nesisindo esingamagremu angu-25, amabhethri ane-electrolyte eqinile yesimo esiqinile awafinyeleli ku-10% wezimpawu ezifanayo zamabhethri e-lithium-ion. nge-electrolyte ewuketshezi. Kusampula ye-AS-LiB Hitachi, lawa ngu-55,6 Wh/l no-20,4 Wh/kg. Kodwa uma siqhathanisa ukuthuthukiswa okusha namabhethri e-nickel-cadmium endaweni, khona-ke konke akukubi kakhulu. Zisinda ngokuphindwe kabili kuphela njenge-nickel-cadmium, kucatshangelwa amandla agciniwe, futhi zingazuza ekuncishisweni kwesisindo somzimba.
Amabhethri e-AS-LiB Hitachi anomunye ubungozi - ukukhiqizwa kufanele kwenzeke ngaphansi kwezimo zomswakama ophansi kakhulu. Izinto ze-Electrode zakha kalula i-hydrogen sulfide lapho zihlanganiswa nomswakama. Ngakho-ke, i-Hitachi ithuthukise ubuchwepheshe kanye nemishini yezimboni yokukhiqiza amabhethri e-lithium-ion e-solid state futhi isilungele ukuthengisa amalayisense ukuhlela ukukhiqizwa kwezinkampani zesithathu. Unjiniyela uzoqala ukulethwa kwezentengiso kwamabhethri e-AS-LiB ngaphambi kuka-Ephreli 2020.
