Wahi a nā hōʻike, ua hoʻomohala nā ʻepekema mai ke Kulanui ʻo Tohoku a me ka High Energy Accelerator Research Organization ma Iapana i kahi conductor lithium superion hydride hou.Ua ʻōlelo ka poʻe noiʻi, ʻo kēia mea hou, i ʻike ʻia ma o ka hoʻolālā ʻana o ka pūʻulu hydrogen (composite anion), e hōʻike ana i ke kūpaʻa kiʻekiʻe loa no ka metala lithium, i manaʻo ʻia e lilo i mea anode hope loa o nā pākahi Solid-state, a hoʻolaha i ka hanau o na mea paa paa a pau me ka ikehu kiekie loa i keia manawa.
Manaʻo ʻia ka pākaukau Solid-state me ka lithium metala anode e hoʻoponopono i nā pilikia o ka leakage electrolyte, flammability a me ka liʻiliʻi o ka ikehu o nā pākahi lithium ion kuʻuna.Manaʻo nui ʻia ʻo ka metala lithium ka mea anode maikaʻi loa no nā pākahi Solid-state āpau, no ka mea, loaʻa iā ia ka mana theoretical kiʻekiʻe a me ka haʻahaʻa haʻahaʻa ma waena o nā mea anode i ʻike ʻia.
ʻO ka Lithium ion conduction solid electrolyte kahi mea nui o nā pākaukau Solid-state, akā ʻo ka pilikia ʻo ka hapa nui o nā electrolytes paʻa i loaʻa i nā kemika/electrochemical instability, kahi e hiki ai ke hoʻoulu i nā hopena ʻaoʻao pono ʻole ma ka interface, e alakaʻi ana i ka piʻi ʻana o ke kūʻē o ka interface. a e hōʻemi nui ana i ka hana ʻana o ka pākaukau i ka wā e hoʻopaʻa pinepine ʻia a hoʻokuʻu ʻia.
Ua ʻōlelo ka poʻe noiʻi ua loaʻa ka manaʻo nui o ka hydride composite i ka hoʻoponopono ʻana i nā pilikia e pili ana i nā anodes metala lithium, ʻoiai lākou e hōʻike nei i ka paʻa kemika a me ka electrochemical maikaʻi i nā anodes metala lithium.ʻO ka electrolyte paʻa hou i loaʻa iā lākou ʻaʻole wale ke kiʻekiʻe ionic conductivity, akā paʻa loa no ka metala lithium.No laila, he holomua maoli ia no nā pākahi Solid-state āpau e hoʻohana ana i ka anode metala lithium.
Ua ʻōlelo ka poʻe noiʻi, "ʻAʻole kōkua kēia hoʻomohala iā mākou e ʻike i nā conductors lithium ion e pili ana i nā hydrides composite i ka wā e hiki mai ana, akā e wehe pū ana i nā ʻano hou i ke kahua o nā mea electrolyte paʻa. kiʻekiʻe ikehu uila uila.
Manaʻo nā kaʻa uila i ka nui o ka ikehu kiʻekiʻe a me nā pihi palekana e hoʻokō i ka laulā ʻoluʻolu.Inā ʻaʻole hiki i nā electrodes a me nā electrolytes ke hui maikaʻi i nā pilikia paʻa electrochemical, e loaʻa mau ka pale ma ke ala i ka hoʻolaha ʻana o nā kaʻa uila.ʻO ka hui kūleʻa ma waena o ka metala lithium a me ka hydride ua wehe i nā manaʻo hou.He palena palena ʻole ka lithium.ʻAʻole mamao loa nā kaʻa uila me ka nui o nā kaukani kilomika a me nā smartphones me hoʻokahi pule.
