U-Hitachi Zosen uqalise ukuhambisa iisampulu zeebhetri ze-lithium-ion zokuqala zoshishino kunye ne-electrode ene-sulfate. I-electrolyte kwiibhetri ze-AS-LiB (ibhetri ye-lithium-ion yonke eqinile) ikwimeko eqinileyo, kwaye ayikho kwimeko yolwelo okanye ijeli, njengakwibhetri ye-lithium-ion yesiqhelo, emisela inani lezinto eziphambili kunye ezizodwa. yemveliso entsha.
Ke, i-electrolyte eqinileyo kwiibhetri ze-AS-LiB ayitshisi, ayiphumi kwaye ayijiki (musa ukujiya) ukuya kumaqondo obushushu asezantsi. Uluhlu oluchaziweyo lobushushu bokusebenza kwiibhetri ze-AS-LiB ngu-β40Β°C ukuya kwi-120Β°C. Ngexesha elifanayo, iiparitha zokusebenza zeebhetri azitshintshi ngokubalulekileyo kulo lonke uluhlu. Ukungabikho kwezinto eziguquguqukayo kuvumela iibhetri ukuba zisebenze kwi-vacuum. Imizimba yabo ayiyi kudumba ngexesha lokusebenza. Kwaye oku akusathethi into yokuba isibetho seebhetri ze-lithium-ion - ingozi yomlilo kunye nokuqhuma - ayisongeli nje le klasi yeebhetri.
Ukuthathela ingqalelo kwiipropati ezidweliswe, iibhetri ze-AS-LiB kulindeleke ukuba zisetyenziswe kwi-spacecraft, izixhobo zonyango kunye nezixhobo zoshishino. Kwixesha elizayo, u-Hitachi Zosen ulindele ukuvelisa iibhetri ze-lithium-ion ze-slide-state zokugcinwa kwamandla okumileyo, ukuhanjiswa kwenethiwekhi kunye nezithuthi zombane.
Ngelishwa, yonke ingqekembe inecala layo. Kwimeko yeebhetri ze-Hitachi AS-LiB, ezi ziphantsi kogcino lwamandla kunye nomlinganiselo ogciniweyo wamandla ukuya kubunzima. Inkampani ayizange ichaze ezi parameters, kodwa ngokujonga isampuli eveziweyo - ibhetri enamacala angama-52 Γ 65,5 Γ 2,7 mm kunye nobunzima be-25 grams, iibhetri ezine-electrolyte eqinile azifikeleli kwi-10% yeempawu ezifanayo zebhetri ye-lithium-ion. nge-electrolyte engamanzi. Kwisampula ye-AS-LiB Hitachi, ezi ziyi-55,6 Wh / l kunye ne-20,4 Wh / kg. Kodwa ukuba sithelekisa uphuhliso olutsha kunye neebhetri ze-nickel-cadmium zendawo, ngoko yonke into ayibi kakhulu. Zinobunzima obuphindwe kabini kuphela njenge-nickel-cadmium, kuthathelwa ingqalelo amandla agciniweyo, kwaye banokuzuza kubunzima bomzimba obuncitshisiweyo.
Iibhetri ze-AS-LiB zeHitachi zinento enye engalunganga - ukuveliswa kufuneka kwenzeke kwiimeko zokufuma okuphantsi kakhulu. Izinto ze-Electrode zenza lula i-hydrogen sulfide xa idityaniswe nokufuma. Ngoko ke, i-Hitachi iphuhlise iteknoloji kunye nezixhobo zoshishino zokuvelisa iibhetri ze-lithium-ion eziqinileyo kwaye zilungele ukuthengisa iilayisensi zokuququzelela ukuveliswa kweenkampani zesithathu. Umphuhlisi uya kuqalisa ukuhanjiswa kweebhetri ze-AS-LiB ngaphambi kuka-Epreli ka-2020.
