Ngokwemibiko, ososayensi abavela eNyuvesi yaseTohoku kanye ne-High Energy Accelerator Research Organization eJapane baye bahlakulela umqhubi omusha we-hydride lithium superion conductor.Abacwaningi bathi le nto entsha, etholakala ngokuklanywa kwesakhiwo se-hydrogen cluster (composite anion), ikhombisa ukuzinza okuphezulu kakhulu kwensimbi ye-lithium, okulindeleke ukuthi ibe yinto yokugcina ye-anode yawo wonke amabhethri e-Solid-state, futhi ikhuthaza ukukhiqizwa kwawo wonke amabhethri e-Solid-state enamandla amakhulu kakhulu kuze kube manje.
Ibhethri ye-Solid-state yonke ene-lithium metal anode kulindeleke ukuthi ixazulule izinkinga zokuvuza kwe-electrolyte, ukuvutha kanye nokuminyana kwamandla okulinganiselwe kwamabhethri endabuko e-lithium ion.Ngokuvamile kunenkolelo yokuthi insimbi ye-lithium iyinto ehamba phambili ye-anode kuwo wonke amabhethri e-Solid-state, ngoba inamandla okucabanga aphezulu kanye namandla aphansi phakathi kwezinto ezaziwayo ze-anode.
I-electrolyte eqinile ye-lithium ion iyingxenye eyinhloko yawo wonke amabhethri e-Solid-state, kodwa inkinga iwukuthi iningi lama-electrolyte aqinile akhona anokuqina kwamakhemikhali/amakhemikhali e-electrochemical, okuzokwenza nakanjani kubangele ukusabela okungadingekile ohlangothini esibonakalayo, okuholela ekwandeni kokumelana nesixhumi esibonakalayo, futhi kunciphisa kakhulu ukusebenza kwebhethri ngesikhathi sokushajwa okuphindaphindiwe nokukhipha.
Abacwaningi baveze ukuthi ama-hydride ayinhlanganisela athole ukunakwa okusabalele ekubhekaneni nezindaba ezihlobene ne-lithium metal anode, njengoba ekhombisa ukuzinza okuhle kakhulu kwamakhemikhali kanye ne-electrochemical maqondana ne-lithium metal anode.I-electrolyte entsha eqinile abayitholile ayigcini nje ngokuba ne-ionic conductivity ephezulu, kodwa futhi izinzile kakhulu kunsimbi ye-lithium.Ngakho-ke, kuwukuphumelela kwangempela kwawo wonke amabhethri e-Solid-state esebenzisa i-lithium metal anode.
Abacwaningi bathi, "Le ntuthuko ayisisizi nje kuphela ukuthi sithole abaqhubi be-lithium ion ngokusekelwe kuma-hydride ahlanganisiwe esikhathini esizayo, kodwa futhi ivula izitayela ezintsha emkhakheni wezinto eziqinile ze-electrolyte. Izinto ezintsha ezitholiwe ze-electrolyte eziqinile kulindeleke ukuthi zikhuthaze ukuthuthukiswa high density energy electrochemical amadivayisi.
Izimoto zikagesi zilindele ukuminyana kwamandla aphezulu kanye namabhethri aphephile ukuze zithole ibanga elanelisayo.Uma ama-electrode nama-electrolyte engakwazi ukubambisana kahle ezindabeni zokuzinza kwe-electrochemical, kuyohlale kunesithiyo emgwaqeni oya ekudumeni kwezimoto zikagesi.Ukubambisana okuphumelelayo phakathi kwe-lithium metal ne-hydride kuye kwavula imibono emisha.I-lithium inamandla angenamkhawulo.Izimoto zikagesi ezinobubanzi bezinkulungwane zamakhilomitha nama-smartphone anokumiswa kweviki elilodwa kungenzeka zingabi kude.
