ʻO ke aniani kalapona electrode i hana ʻia mai ka nano oxide he mau ʻano ʻano like ʻole, e like me ke kūpaʻa maikaʻi o nā pihi, conductivity kiʻekiʻe, maʻemaʻe kiʻekiʻe, ʻaʻohe kinoea i ka electrode Essence.ʻO ka hana hou ʻana o ka ʻili maʻalahi, ka hydrogen liʻiliʻi a me ka hiki ke oxygen, ke kumu kūʻai liʻiliʻi, a me nā mea ʻē aʻe.
ʻO ka mea mua, e koho i ka 10-100g/L anawaena o 10-100g/L anawaena ma waena o 0.05-10 μm o TiO2, SiO2, Cr2O3, ZrO2, CeO2, Fe2O3, BaSO, SiC i loko o nā mea paʻa MgO;ʻO nā mea i hana ʻia e like me nā lithium ion he mau hiʻohiʻona o ka hoʻopiʻi maikaʻi ʻana a me ka hoʻokuʻu ʻana i ka maikaʻi, ka mana kiʻekiʻe, a me ka hana circulatory paʻa.
ʻO ka lua, ʻo ka lithium battery positive material, nano -magnesium oxide ma ke ʻano he conductive dopant, hoʻopuka i ka magnesium doped lithium iron manganese phosphate ma o ka hoʻoponopono ʻana i nā kumu, a hana hou i kahi nano-structure o ka mea electrode maikaʻi.ʻO kona hiki ke hoʻokuʻu maoli i ka 240mAh / g.ʻO kēia ʻano hou o nā mea electrode maikaʻi nā hiʻohiʻona o ka ikehu kiʻekiʻe, palekana, a me nā kumukūʻai haʻahaʻa.He kūpono ia no ka wai a me ka colloidal lithium-ion batteries, nā polymers liʻiliʻi a me ka liʻiliʻi, ʻoi aku hoʻi no nā pihi mana kiʻekiʻe.
A laila, ua hoʻonui ʻia ka mana a me ka hana pōʻai o ka pākaukau lithium manganate spinel.I loko o ka lithium ion pākahi electrolyte me ka spinel lithium manganate ma ke ʻano he mea maikaʻi, ua hoʻohui ʻia ka nano-magnesium oxide e like me ka deacidifier e wehe i ka waikawa, ʻo ka nui o ka hoʻohui ʻana he 0.5-20% o ke kaumaha o ka electrolyte.Ma ka deacidizing i ka electrolyte, ua ho'ēmiʻia ka maʻiʻo o ka HFʻakika manuahi i loko o ka electrolyte i lalo o 20ppm, e hoʻemi ana i ka hoʻoheheʻeʻana o HF i LiMn2O4, a hoʻonui i ka hiki a me ka hana pōʻai o LiMn2O4.
ʻO ka mea hope loa, ma ka hana mua, ua hui pū ʻia ka nano magnesium oxide ma ke ʻano he pH regulator me kahi solution alkali a me ka solution ammonia ma ke ʻano he mea paʻakikī, a hoʻohui ʻia i ka wai i hui pū ʻia me nā paʻakai cobalt a me ka nickel e hoʻoheheʻe i ka Ni-CO complex hydroxides. .
ʻO ka hana ʻelua, ʻo ia ka hoʻohui ʻana i ka lithium hydroxide i ka Ni-CO composite hydroxide, a me ka hui ʻana o ka mālama ʻana i ka wela ma 280-420 °C.
Ma ke kolu o ka hana, ka huahana i hanaia ma ka lua o ka hana ua wela ia ma ke kaiapuni o 650-750 ° C, e pili ana i ka manawa o ka ua.Ke emi nei ka nui o ka nui o ka lithium composite oxide a i ʻole ke piʻi ʻana o ka puʻupuʻu nui.Ke hoʻohana ʻia ka lithium composite oxide ma ke ʻano he anode active material, hiki ke loaʻa kahi kiʻekiʻe lithium ion second battery, a ʻo ka nui maoli o ka magnesium oxide e pili ana i ke ʻano kikoʻī.
