Loaʻa nā mea lithium anode kaʻa ikehu houtungsten oxide WO3 nanoparticles.

I ka hana ʻana i nā kaʻa ikehu hou, hiki i ka hoʻohana ʻana i nā mea lithium anode i loaʻa i ka tungsten oxide melemele ke hāʻawi i ka ikehu no ka pā uila a hoʻomaikaʻi i ka hana kumukūʻai o ke kaʻa.
E pili ana i ka ʻoihana kaʻa ikehu hou, ʻo ka ʻāpana pākaukau ke kumu o ka ʻenehana uila ʻekolu. E like me nā limahana kūpono, i ka makahiki 2019, ʻo ka pūʻulu mua o ka ʻōnaehana uila kaʻa kaʻa kaʻa kaʻa ikehu o 160Wh/Kg a ʻoi aku paha. , He 15 mau hiʻohiʻona, kēlā me kēia BYD, CITIC Guoan, GAC Group, Jianghuai Ting, Ningde Times, PHYLION, DFD, Tianjin Jiewei, Shanghai DLG, Ningbo Viri. ʻO nā ʻōnaehana pākaukau i kūkulu ʻia e lākou a pau e pili ana i nā bateria ternary. Hōʻike ka poʻe loea. i loko o ke kaʻina hana o nā mea lithium anode, hoʻohui i ka nano melemele tungsten oxide hiki ke hana i ka pākaukau i ʻoi aku ka kiʻekiʻe o ke kumukūʻai, a laila hoʻomaikaʻi i ka hoʻokūkū o nā kaʻa ikehu hou i ka mākeke honua. hoʻohana ʻia e like me ka mea lithium anode ʻo ia ka tungsten oxide melemele i ka pono o ka ikehu kiʻekiʻe a me ke kumu kūʻai haʻahaʻa.

Nano melemele tungsten trioxide, WO3 pauka, He mea kūikawā nonorganic N-type semiconductor, hiki ke hoʻohana ʻia e hoʻomākaukau i nā mea electrode kumu kūʻai, ʻo ia hoʻi, ʻo ka hoʻomākaukau wikiwiki ʻana i ka pahu lithium ʻaʻole i ʻoi aku ka kiʻekiʻe o ka hana electrochemical, akā haʻahaʻa hoʻi ke kumu kūʻai. ka mākeke, ʻoi aku ka nui o ka hoʻohana ʻana i nā pā lithium i loko o ka nanometer tungsten pauka, a hiki ke hāʻawi i ka ikehu kūpono no nā kaʻa ikehu hou, nā mea hana mana, nā kelepona paʻi lima, nā kamepiula a me nā mea hana ʻē aʻe.

ʻO nā pahu lithium Ternary a me ka lithium iron phosphate batteries e noho ana i ka mainstream o ka mākeke. Akā naʻe, loaʻa iā lākou kekahi mau drawbacks, e like me ka palena palena no ka hoʻomaikaʻi ʻana i ka ikehu.

ʻO ke ʻano hoʻomohala ʻenehana o nā mea lithium cathode

ʻO Orthosilicate, layered lithium-rich manganese-based, sulfide-based cathode materials ka mea wela o ka noiʻi o kēia manawa. ʻO ka hapalua wale nō o ka mana theoretical. Ma waho aʻe o ka ikehu kikoʻī kiʻekiʻe, ʻoi aku ka maikaʻi o ka base lithium waiwai manganese i ke kumu kūʻai kūpono.Ma mua o kēia, pono e ʻimi i kahi ʻano hana kūpono. ʻO nā mea cathode i hoʻokumu ʻia i ka sulfur i loaʻa ka ikehu o 2600Wh / kg, akā maʻalahi ka hoʻonui ʻana o ka leo i ke kaʻina hana a me ka hoʻokuʻu ʻana, pono e hoʻomaikaʻi.
ʻO ke ʻano hoʻomohala ʻenehana o nā mea lithium anode

ʻO Graphene, lithium titanate a me ka nano yellow tungsten oxide ka mea hoihoi loa i ka lithium anode. mea anode.He lōʻihi ke ola o ka Lithium titanate, a ʻoi aku ma mua o 10,000 mau manawa, a hiki ke hoʻopiʻi koke ʻia, ʻoi aku ka maikaʻi no ka wahi ʻaʻole pono ke kahua mālama ikehu.ʻO ka Nano yellow tungsten oxide kahi mea electrode kūikawā me ka mana theoretical o 693mAh / g a me ka hana electrochromic maikaʻi loa.Eia kekahi, loaʻa iā ia nā pōmaikaʻi o ke kumu kūʻai haʻahaʻa, ka nui o nā mālama a me ka non-toxicity.

I ka hopena, hiki ke hoʻohana ʻia ka nano-sized tungsten oxide WO3 i mea electrode a hoʻohana ʻia i nā kaʻa ikehu hou.

Ke hoʻolako nei ʻo Guangzhou Hongwu Material Technology Co., Ltdnano melemele tungsten trioxide WO3ma ka nui, me ka puka o ka mahina ma mua o 2 tons.Ke alakaʻi ʻia nei e nā kaʻa ikehu hou, ke hoʻonui mālie nei mākou i ka laina hana, hāʻawi i nā huahana ʻoi aku ka maikaʻi no ka mākeke, a hāʻawi i kahi haʻahaʻa haʻahaʻa i ka māla ikehu hou.
