Ngokweengxelo, izazinzulu ezivela kwiYunivesithi yaseTohoku kunye ne-High Energy Accelerator Research Organisation eJapan ziye zavelisa i-composite entsha ye-hydride lithium superion conductor.Abaphandi bathi le nto intsha, eyenziwa ngokuyilwa kweqela le-hydrogen (i-anion composite) isakhiwo, ibonisa uzinzo oluphezulu kakhulu lwe-lithium metal, ekulindeleke ukuba ibe yinto yokugqibela ye-anode yayo yonke ibhetri ye-Solid-state, kwaye ikhuthaza ukuveliswa kwayo yonke ibhetri ye-Solid-state enoxinano lwamandla aphezulu ukuza kuthi ga ngoku.
Ibhetri ye-Solid-state yonke kunye ne-lithium metal anode kulindeleke ukuba isombulule iingxaki zokuvuza kwe-electrolyte, ukutsha kunye nokuxinwa kwamandla okuncinci kweebhetri ze-lithium ion zendabuko.Ngokuqhelekileyo kukholelwa ukuba isinyithi se-lithium sisona sixhobo se-anode esingcono kunazo zonke ibhetri ye-Solid-state, kuba inomthamo ophezulu wethiyori kunye neyona nto iphantsi kakhulu phakathi kwezinto eziziwayo ze-anode.
I-Lithium ion conduction i-electrolyte eqinileyo yinxalenye ephambili yazo zonke ibhetri ye-Solid-state, kodwa ingxaki kukuba uninzi lwe-electrolyte ekhoyo ekhoyo inokungazinzi kweekhemikhali / i-electrochemical, nto leyo eya kubangela ukuphendulwa kwecala ngokungeyomfuneko kwi-interface, ekhokelela ekwandeni kokumelana nojongano, kunye nokunciphisa kakhulu ukusebenza kwebhetri ngexesha lokuhlawuliswa okuphindaphindiweyo kunye nokukhupha.
Abaphandi baye baxela ukuba i-hydrides edibeneyo ifumene ingqwalasela ebanzi ekujonganeni nemiba enxulumene ne-lithium metal anode, njengoko ibonisa ukuzinza kweekhemikhali kunye ne-electrochemical egqwesileyo ngokubhekiselele kwi-lithium metal anodes.I-electrolyte entsha eqinileyo abayifumeneyo ayinayo kuphela i-ionic conductivity ephezulu, kodwa kwaye izinzile kakhulu kwisinyithi se-lithium.Ke ngoko, luyimpumelelo yokwenyani kuyo yonke ibhetri ye-Solid-state isebenzisa i-lithium metal anode.
Abaphandi bathi, "Olu phuhliso alusincedanga nje ukuba sifumane abaqhubi be-lithium ion ngokusekelwe kwi-hydrides edibeneyo kwixesha elizayo, kodwa kwakhona kuvula iindlela ezintsha kwintsimi yezinto eziqinileyo ze-electrolyte. Izinto ezintsha ezifunyenweyo ze-electrolyte eziqinileyo kulindeleke ukuba zikhuthaze ukuphuhliswa izixhobo ze-electrochemical density ephezulu.
Izithuthi zombane zilindele ukuxinana kwamandla aphezulu kunye neebhetri ezikhuselekileyo ukufikelela kuluhlu olwanelisayo.Ukuba i-electrodes kunye ne-electrolytes ayikwazi ukusebenzisana kakuhle kwimiba yokuzinza kwe-electrochemical, kuya kuhlala kukho umqobo endleleni eya ekudumeni kwezithuthi zombane.Intsebenziswano eyimpumelelo phakathi kwensimbi ye-lithium kunye ne-hydride ivule iingcamango ezintsha.I-Lithium inamandla angenamkhawulo.Iimoto zombane ezinoluhlu lwamawaka eekhilomitha kunye nee-smartphones ezineveki enye yokulinda zisenokungabi kude.
