Nā mea hoʻolālā no nā Bateri Lithium

Ma ka pōʻaiapili o ke kalapona neutrality a me ke au honua o ka electrification kaʻa, lithium, ma ke ano he mea nui i loko o ke kahua pākaukau, ua manaoia e hoomau i ka pomaikai mai ka hoʻololi ikehu maʻemaʻe i loko o kona mana a me ka ikehu kahua mālama.Loaʻa i ka Lithium kahi kaulahao ʻoihana piha, e hana ana i nā huahana mai nā ores upstream a me nā loko paʻakai a hiki i ke kahawailithium carbonate, lithium hydroxide a me metal lithium, a me nā ʻoihana kuʻuna i lalo (metal smelting, lubricants, ceramic glass, etc.), nā mea hou (organic synthesis, biomedicine) a me ka ikehu hou (3C batteries, power batteries, etc.) a me nā ʻaoʻao ʻē aʻe. nā kaulahao ʻoihana piha.Lithium hydroxideʻo ia kekahi o nā paʻakai lithium kumu ʻekolu i loko o ke kaulahao ʻoihana lithium.ʻO ka noi o lalo e hele mai ana mai ke kahua pākaukau mana, ke kahua pākaukau mea kūʻai aku, a me ke kahua ʻoihana i hōʻike ʻia e ka hana ʻana o ka lithium based grease a me nā ceramics aniani.ʻO kāna mau ʻano nui he Lithium hydroxide (LiOH) a me ka lithium hydroxide monohydrate (LiOH·H2O).

He mea waiwai nui ka Lithium hydroxide i ke kahua o nā ʻōhua mana, ʻoi aku ka nui o ka nickel ternary cathode material i hoʻohana nui ʻia i nā ʻenekini mana kiʻekiʻe, a he kumu lithium kumu nui i kāna hana.Hoʻokaʻawale nui ʻia nā mea nickel ternary kiʻekiʻe i NCM811 a me NCA.Hoʻopuka nui nā hui Kina i ka NCM811, a ʻo nā hui Kepani a me Korea ka nui o ka NCA.I kēia manawa, ʻoi aku ka nui o nā kaʻa ikehu hou i hoʻolako ʻia me nā pihi nickel ternary kiʻekiʻe ma mua o 500km.ʻO ka ʻāpana pākahi o nā mea kūʻai aku ka nui o nā smartphones, nā papa, nā polokalamu TWS, a me nā drones.

Pono nā mea nickel ternary kiʻekiʻe he 700 ~ 800 ° C ka mahana sintering, akā hoʻomaʻamaʻa pinepine ʻia ka lithium carbonate ma kahi o 900 ° C no ka hoʻohana ʻana i nā waiwai waiwai kūpono, ʻoiai ʻo ka helu heheʻe o ka lithium hydroxide he 471 ° C, me ka ikaika reactivity a me ka corrosiveness ikaika.ʻO kāna mau waiwai kino a me nā mea kemika e hoʻolilo i ka lithium hydroxide i mea nui no ka synthesis thermal o nā mea cathode nickel ternary kiʻekiʻe, no laila he koho hiki ʻole ia no nā mea kiʻekiʻe-nickel ternary.

ʻO nā ʻoihana pākaukau ʻekolu kiʻekiʻe ma ka honua e pili ana i ka hiki ke hoʻokomo ʻia o nā pihi mana i hōʻike maopopo ʻia ʻo ke kiʻekiʻe-nickel ternary ke ala hoʻomohala nui (Ningde era - NCM622/811, Japan's Panasonic - NCA, South Korea's LG Chem - NCM622 /811), ʻo ka māhele mākeke o CR3 i hōʻea ma kahi o ʻelua hapakolu ʻoiai e mālama ana i kahi ulu ulu kiʻekiʻe.I ka wā e hiki mai ana, me ka hoʻonui ʻana i ka mana o ka nickel ternary kiʻekiʻe i nā kaʻa ikehu hou, ʻo ka lithium hydroxide ma ke ʻano he kumu kumu e hoʻokomo pū i kahi ulu ulu ʻole.
