ʻO ka ʻoihana kiaʻi palekana ka ulu ʻana o ka hoʻokele waiwai o Kina, nā kulekele ʻāina e hāpai i kahi ʻoihana o ka lā, ʻo ia ka hoʻomohala ʻana i ka ikehu hou, ka mālama ʻana i ke kaiapuni, kahi ʻoihana koʻikoʻi koʻikoʻi, akā ʻo ke kūkulu ʻana i ka ʻōnaehana palekana a me ka mālama ʻana.Wahi a "ʻoihana palekana o Kina" 13 ʻElima "hoʻolālā hoʻolālā" e kuhikuhi ana ma ka 2020 e piʻi aku ka ʻoihana mālama palekana o Kina ma mua o 50 biliona yuan.I kēia manawa, ua ʻike ʻia ka ʻoihana mālama mālama mālama home lithium e nā ʻoihana home he nui i nā kahua pili.Wahi a nā ʻikepili kūpono, ʻo 2015 a hiki i kēia lā, ʻo ka nui o nā hoʻouna ʻana o ka ʻoihana mālama mālama mālama home ma kahi o 160 miliona, 2018 e manaʻo ʻia e moku ma kahi o 160 miliona.Wahi a ka Foresight Industry Research Institute e hāʻawi i ka ʻikepili ʻoihana i lalo e hōʻike ana i ka ʻoihana nānā palekana e like me ke kaulahao ʻoihana holoʻokoʻa i ka ʻoihana ulu nui loa, ma muli o kāna mau hiʻohiʻona ʻoihana a me nā hiʻohiʻona koi ʻoihana i lalo aia kekahi mau ʻokoʻa, no laila ka wahi ʻoihana e hiki mai ana. nui loa.
E like me ka mea i hoʻohana nui ʻia i loko o ka ʻoihana kiaʻi palekana, ʻo ka pā lithium, kāna mau noi e uhi i nā ʻano pākaukau like ʻole, e like me nā ʻāpana lua lithium-ion a me nā ʻāpana lithium-ion tertiary.ʻO nā pākahi lithium-ion i hoʻohana ʻia i ka ʻoihana palekana he electrolyte paʻa (electrolyte), a hiki ke hoʻokaʻawale ʻia ka electrolyte paʻa i ke kaʻina hana i ʻelua ʻano o ka hoʻoheheʻe ʻana i ka mahu a me ke ʻano electrodialysis.ʻO ke ʻano o ka hoʻoheheʻe ʻana i ka mahu kemika he hana ia e hoʻomākaukau ʻia ai ka electrolyte paʻa (e like me ka silicon dioxide, lead dioxide) i hui pū ʻia me nā mea hao oxide ma mua o ka manganese oxide a i ʻole alumini oxide, a laila loaʻa kahi kiʻiʻoniʻoni lahilahi e ka electrolyte. ka pane ʻana ma ke ʻano he anode organik.ʻO ka pōmaikaʻi nui ke kumu kūʻai haʻahaʻa a me ke ola pōʻai lōʻihi;ʻO ka hemahema, pono e hui pū ʻia ka hoʻohana ʻana me ka hoʻohui ʻana i nā reagents kōkua (e like me nā plasticizers) no nā mea hoʻohui, ʻo ia ke kumu kūʻai;a inā ʻaʻole hoʻohui ʻia nā reagents kōkua, e hana ʻia ka nui o nā kinoea ʻona (formaldehyde, carbon dioxide) i ka wā o ka hoʻohana ʻana;Eia kekahi, ʻaʻole hiki ke hana hou ʻia a ʻaʻole hiki ke hoʻohana pono ʻia.Mai ka hoʻomohala ʻana, ʻoi aku ka nui o ka nānā ʻana i kāna hoʻohana ʻana ma ke ʻano he mea mālama ikehu.
I nā makahiki i hala iho nei, ka hoʻomohala ʻana a me ka hoʻohana ʻana onā pākahi lithium-ionua lilo i mea nui.Eia nō naʻe, no ka nui o nā pilikia me nā pākahi lithium-ion, e like me ka hana paʻa ʻole, ka pōkole o ke ola a me ka palekana haʻahaʻa, pono e hoʻolōʻihi i ka wikiwiki o ka noiʻi a me ka hoʻomohala ʻana e aʻo a hoʻoponopono i kēia mau pilikia.Wahi a nā wānana, ma ka 2020, manaʻo ʻia ke kūʻai aku ʻana o nā kaʻa kaʻa hou o Kina i 200,000 mau ʻāpana.Ma waena o lākou, ʻoi aku ka nui o ka mākeke o nā pā lithium-ion no nā kaʻa akamai ma mua o 3.6 biliona yuan.
I kēia manawa,ʻo nā mea nui maikaʻi a maikaʻiʻole i hoʻohanaʻia i nā pākahi lithium-ion: 1. NCM622 / 623: Ma lalo o ke kumu o ke kumu kūʻai haʻahaʻa, hoʻohanaʻiaʻo NCM522 e like me ka anode, hiki ke loaʻa kahi kiko'ī kiko'ī kiʻekiʻe, a me nā pono o ka ka hana electrochemical paʻa, palekana maikaʻi a me ke ola pōʻai lōʻihi;2. ʻO GaN-based: ʻO ka mea pono pono'ī he mau waiwai kino a me ke kino, e like me ke kū'ēʻana i ka corrosion, ke kumu kūʻai haʻahaʻa, ka hana kiʻekiʻe a me nā mea pōʻino'ē aʻe e hālāwai me ka ʻO ka electrode maikaʻiʻole o ka puʻupuʻu he kūpono no ka lithium ion ke hōʻike i ka hana palekana maikaʻi.Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ʻoi aku ka nui o nā mea hana hou i puka mai, e like me nā mea ternary.I kēia manawa, aia kahi ternary e like me ka electrode maikaʻi ʻole o nā pā lithium Pack ma ka mākeke, ʻo kona palekana a me ka ikaika o ka ikehu ma mua o ka honua, a me nā kumu kūʻai haʻahaʻa, hiki ke hoʻohana ʻia i nā mea kūʻai aku.E kū mau ana ka wā e hiki mai ana i nā pilikia e pili ana i ka palekana a me ka hoʻomalu maikaʻi.
Mai ka ʻike loea, me ka hoʻohana ākea onā pākahi lithiumma ke kahua o ka palekana, ua hōʻike ʻia ka ʻoihana pākaukau lithium holoʻokoʻa e nā pale ʻenehana kiʻekiʻe, nā pale patent kiʻekiʻe a me ka ʻike haʻahaʻa haʻahaʻa.Wahi a ka ʻikepili o nā hōʻike semi-makahiki o nā ʻoihana lithium-ion e hōʻike ana i ka makahiki 2017, ʻoi aku ka nui o ka hana pākaukau lithium-ion o Kina a me ke kūʻai aku ma mua o ka piliona watt mau hola.Ma waena o lākou, ke alakaʻi nei nā hui pākahi lithium-ion home 16 i ka ʻoihana;ʻO nā hui pākahi lithium haole me nā hui SMC, FPC a me NCA.Ma keʻano kikoʻī, aia ʻeono mau hui ma ke kahua o ka mākeke huahana palekana ma mua o 10%, kahi o ka mākeke o Skywing Intelligence i hiki i 14.5%, CASS Technology, Lixin battery a me Zhongying Electronics market share o 9.5%, 7.7% a me 5.2 %, kēlā me kēia.
