Ka hana ʻana i nā mea maikaʻi a maikaʻi ʻole

I ka hoʻomākaukau ʻana i nā mea electrode inorganic no nā pākahi lithium ion, ʻoi aku ka nui o ka hoʻohana ʻana i ke kiʻekiʻe kiʻekiʻe.ʻO ka hopena paʻa paʻa kiʻekiʻe: e pili ana i ke kaʻina hana e hana ai nā reactants me nā mea paʻa paʻa no kekahi manawa ma kahi mahana a hana i nā hopena kemika ma o ka hoʻopuehu ʻana ma waena o nā mea like ʻole e hana i nā pūhui kūpaʻa loa i kekahi mahana. , e pili ana i ka hopena paʻa-paʻa, ka hopena paʻa-kino a me ka hopena paʻa-wai.

ʻOiai ke hoʻohana ʻia ke ʻano sol-gel, coprecipitation method, hydrothermal method a me solvothermal method, solid-phase reaction a solid-phase sintering i ka wela kiʻekiʻe.ʻO kēia no ka mea e pono ai ke kumu hana o ka pākaukau lithium-ion e hiki i kāna mea electrode ke hoʻokomo pinepine a hoʻoneʻe i ka li +, no laila pono e lawa ka paʻa o kona ʻano lattice, pono e kiʻekiʻe ka crystallinity o nā mea hana a pono ke ʻano maʻamau. .He paʻakikī kēia e hoʻokō ma lalo o nā kūlana haʻahaʻa haʻahaʻa, no laila, loaʻa maoli nā mea electrode o nā pā lithium-ion i hoʻohana maoli ʻia i kēia manawa ma o ka hopena solid-state kiʻekiʻe.

ʻO ka laina hana hana cathode ka mea nui e pili ana i ka ʻōnaehana hui ʻana, ka ʻōnaehana sintering, ka ʻōnaehana hoʻoheheʻe, ka ʻōnaehana holoi wai (ʻo ka nickel kiʻekiʻe wale nō), ka ʻōnaehana hoʻopili, ka ʻōnaehana lawe pauka a me ka ʻōnaehana naʻauao.

Ke hoʻohana ʻia ke kaʻina hui ʻana i ka hana ʻana i nā mea cathode no nā pā lithium-ion, ʻike pinepine ʻia nā pilikia maloʻo.ʻO nā mea hoʻoheheʻe like ʻole i hoʻohana ʻia i ke kaʻina hui ʻana i ka pulu e alakaʻi i nā kaʻina hoʻomaloʻo like ʻole a me nā mea hana.I kēia manawa, ʻelua ʻano mea hoʻoheheʻe i hoʻohana ʻia i ke kaʻina hui ʻana: nā mea hoʻoheheʻe wai ʻole, ʻo ia hoʻi nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, acetone, etc.Mea hoʻoheheʻe wai.ʻO nā mea hoʻomaloʻo no ka hui ʻana o ka lithium-ion battery cathode material ka mea nui: ka mea hoʻomaloʻo rotary, ka mea maloʻo rake, ka mea maloʻo, ka mea maloʻo kāʻei.

ʻO ka hana ʻoihana o nā mea cathode no nā pā lithium-ion e hoʻohana maʻamau i ke kaʻina hana synthesis synthesis solid-state kiʻekiʻe, a ʻo kāna kumu a me nā mea kī nui he sintering kiln.Hoʻohui like ʻia a maloʻo nā mea maka no ka hana ʻana o nā mea lithium-ion battery cathode, a laila hoʻouka ʻia i loko o ka kiln no ka sintering, a laila hoʻokuʻu ʻia mai ka kiln i ke kaʻina hana a me ka hoʻokaʻawale ʻana.No ka hana ʻana i nā mea cathode, ʻo nā mea ʻenehana a me ka hoʻokele waiwai e like me ka wela o ka mālama ʻana i ka mahana, ka like ʻana o ka mahana, ka mālama ʻana i ka lewa a me ke kūlike, ka hoʻomau, ka mana hana, ka hoʻohana ʻana i ka ikehu a me ka pae automation o ka kiln.I kēia manawa, ʻo nā mea hana sintering nui i hoʻohana ʻia i ka hana ʻana i nā mea cathode he pusher kiln, roller kiln a me ka bele jar furnace.

◼ ʻO Roller kiln kahi kīnaʻi ʻāwīwī liʻiliʻi me ka hoʻomehana mau a me ka sintering.

◼ Wahi a ka lewa umu, e like me ke kiln pusher, ua mahele pū ʻia ka kiln roller i ke kiln ea a me ka kiln ea.

• Air kiln: hoʻohana nui ʻia no nā mea sintering e koi ana i ka lewa oxidizing, e like me nā mea lithium manganate, nā mea lithium cobalt oxide, nā mea ternary, etc.
• Kiln Atmosphere: hoʻohana nui ʻia no ka NCA ternary material, lithium iron phosphate (LFP) material, graphite anode material a me nā mea sintering e pono ai ka lewa (e like me N2 a i ʻole O2) pale kinoea.

◼ Hoʻohana ʻia ke kaʻina hana kuʻekuʻe ʻōwili, no laila ʻaʻole e hoʻopilikia ʻia ka lōʻihi o ka kiln e ka ikaika propulsion.ʻO ka manaʻo, hiki ke palena ʻole.ʻO nā hiʻohiʻona o ka hale kiln cavity, ʻoi aku ka maikaʻi o ka paʻa ʻana i ka wā e puhi ai i nā huahana, a ʻoi aku ka maikaʻi o ka hoʻoneʻe ʻana o ka ea i loko o ka umu a me ka hoʻoheheʻe ʻana o ka wai a me ka hoʻokuʻu ʻana o nā huahana.ʻO ia ka mea i makemake ʻia e hoʻololi i ka kiln pusher e ʻike maoli i ka hana nui.

◼ I kēia manawa, hoʻopaʻa ʻia ka lithium cobalt oxide, ternary, lithium manganate a me nā mea cathode ʻē aʻe o nā pā lithium-ion i loko o kahi kiln air roller, ʻoiai ua hoʻopaʻa ʻia ka lithium iron phosphate i loko o kahi kiln roller i pale ʻia e ka nitrogen, a ua hoʻopaʻa ʻia ka NCA i loko o kahi roller. kiln i pale ʻia e ka oxygen.
