I loko o ka manawa "Hoʻolālā ʻumikūmākolu makahiki ʻelima", ua ulu wikiwiki ka hana ʻana a me ke kūʻai aku ʻana o Kina i nā kaʻa ikehu hou, ʻoi aku ka mua ma ka honua no ʻelima mau makahiki.Manaʻo ʻia e ʻoi aku ka nui o nā kaʻa ikehu hou ma mua o 5 miliona ma ka hopena o kēia makahiki.I ka manawa like, ke hoʻomau nei ka nūhou maikaʻi mai Kina i ka ʻenehana kumu o nā ʻenekini hou.Ua alakaʻi ʻo Chen Liquan, he 80 mau makahiki, ka mea mua ma ka ʻoihana pākaukau lithium o Kina, i kāna hui e hoʻomohala i nā mea pākaukau hou.
Hoʻokuʻu ʻia ka pākaukau lithium nano-silicon hou, me ka nui o 5 mau manawa o ka pā lithium kahiko
ʻO Chen Liquan, he kanaka hoʻonaʻauao 80 makahiki o ka Chinese Academy of Engineering, ʻo ia ka mea nāna i hoʻokumu i ka ʻoihana pākahi lithium o Kina.I nā makahiki 1980, ua alakaʻi ʻo Chen Liquan a me kāna hui i ke alakaʻi ʻana i ka noiʻi ʻana i nā electrolytes paʻa a me nā ʻeke lithium lua ma Kina.I ka makahiki 1996, ua alakaʻi ʻo ia i kahi hui noiʻi ʻepekema e hoʻomohala i nā pā lithium-ion no ka manawa mua ma Kina, ua alakaʻi i ka hoʻoponopono ʻana i nā pilikia ʻepekema, ʻenehana a me ka ʻenekinia o ka hana nui o nā pā lithium-ion home, a ʻike i ka ʻenehana. o na paiki lithium-ion hale.
Ma Liyang, Jiangsu, ua alakaʻi ʻo Li Hong, he protégé o Academician Chen Liquan, i kāna hui e hoʻokō i kahi holomua i loko o kahi kumu waiwai nui no nā pā lithium ma hope o 20 mau makahiki o ka noiʻi ʻenehana a me ka hana nui ma 2017.
ʻO ka mea nano-silicon anode kahi mea hou i hoʻomohala kūʻokoʻa e lākou.ʻO ka mana o nā pihi pihi i hana ʻia mai ia mea he ʻelima mau manawa ma mua o nā pākahi lithium graphite kahiko.

Loaʻa ka silikoni ma ke ʻano a he nui i nā mālama.ʻO ka mea nui o ke one he silica.Akā, no ka hana ʻana i ke silika metala i mea anode silicon, pono ka hana kūikawā.I loko o ka hale hana, ʻaʻole paʻakikī ka hoʻopau ʻana i ia kaʻina hana, akā no ka hana ʻana i nā mea anode silicon-level e pono ai ka nui o ka noiʻi ʻenehana a me nā hoʻokolohua.
Ke noiʻi nei ka Institute of Physics of the Chinese Academy of Sciences i ka nano-siliconi mai ka makahiki 1996, a ua hoʻomaka i ke kūkulu ʻana i kahi laina hana anode silicon ma 2012. ʻAʻole i ka makahiki 2017 i kūkulu ʻia ka laina hana mua, a ua hoʻoponopono mau ʻia. a hooponopono hou ia.Ma hope o nā tausani o nā hāʻule, ua hana nui ʻia nā mea anode silicon.I kēia manawa, hiki i ka hale hana Liyang ke hoʻopuka makahiki o nā mea anode silicon no nā pā lithium-ion hiki ke hiki i 2,000 tons.
Inā he koho maikaʻi nā mea anode silicon no ka hoʻomaikaʻi ʻana i ka nui o ka ikehu o nā pā lithium i ka wā e hiki mai ana, a laila ʻike ʻia ka ʻenehana ʻenehana solid-state i mea e hoʻoponopono ai i nā pilikia o kēia manawa e like me ka palekana a me ke ola pōʻaiapuni o nā pā lithium.I kēia manawa, nui nā ʻāina e hoʻomohala ikaika nei i nā ʻenekini paʻa, a ʻo ka noiʻi ʻana a me ka hoʻomohala ʻana o Kina i ka ʻenehana pākaukau lithium solid-state e mālama pū ana me ka honua.
I loko o kēia hale hana ma Liyang, ʻo nā drones e hoʻohana ana i nā pākahi lithium solid-state i hoʻomohala ʻia e kahi hui i alakaʻi ʻia e Profesor Li Hong he 20% lōʻihi ka lōʻihi ma mua o nā drones me nā kikoʻī like.Aia ka mea huna i kēia mea ʻeleʻele ʻeleʻele, ʻo ia ka solid-state cathode material i hoʻomohala ʻia e ka Institute of Physics, Chinese Academy of Science.
I ka makahiki 2018, ua hoʻopau ʻia ka hoʻolālā a me ka hoʻomohala ʻana o kahi ʻōnaehana uila ikaika 300Wh/kg.Ke kau ʻia ma luna o kahi kaʻa, hiki iā ia ke pālua i ka laulā holo o ke kaʻa.I ka makahiki 2019, ua hoʻokumu ka Chinese Academy of Science i kahi laina hana pailaka paʻa paʻa ma Liyang, Jiangsu.Ma Mei o kēia makahiki, ua hoʻomaka nā huahana e hoʻohana i nā huahana uila.
Eia naʻe, ua haʻi aku ʻo Li Hong i nā mea hoʻolaha ʻaʻole kēia he pākaukau paʻa paʻa i ke ʻano holoʻokoʻa, akā he pākaukau quasi-solid-state i hoʻopaʻa mau ʻia i ka ʻenehana ʻenehana lithium wai.Inā 'oe makemake e hana i na kaʻa i ka lōʻihi laulā, kelepona hele i lōʻihi standby manawa, aʻaʻohe mea hiki No ka mokulele e lele kiʻekiʻe a oi aku, ia mea pono e hoʻomōhala i ka palekana a me ka nui-kaha a pau-paʻa-moku'āina kumu.
Ke puka mai nei nā pila hou ma hope o kekahi a ke kūkulu ʻia nei ʻo "Electric China".
ʻAʻole wale ka Institute of Physics of the Chinese Academy of Sciences, nui nā hui e ʻimi nei i nā ʻenehana hou a me nā mea hana no nā pihi ikehu hou.Ma kahi hui ikehu hou ma Zhuhai, Guangdong, ke hoʻopaʻa ʻia nei kahi kaʻa kaʻa uila maʻemaʻe ma kahi hōʻike hōʻikeʻike o ka hui.
Ma hope o ka hoʻouka ʻana no ʻekolu mau minuke, ua hoʻonui ka mana i koe mai 33% a ʻoi aku ma mua o 60%.I loko o 8 mau minuke, ua hoʻopiha piha ʻia ke kaʻa, e hōʻike ana he 99%.
Ua haʻi aku ʻo Liang Gong i nā mea hoʻolaha ua paʻa nā ala kaʻa kaʻa o ke kūlanakauhale a ʻaʻole e ʻoi aku ka mile mile no kahi huakaʻi hele ma mua o 100 mau kilomita.ʻO ka hoʻopaʻa ʻana i ka manawa hoʻomaha o ke kaʻa kaʻa hiki ke hāʻawi i ka pāʻani piha i nā pono o nā pākahi lithium titanate e hoʻopaʻa wikiwiki ana.Eia kekahi, loaʻa i nā pākahi lithium titanate nā manawa pōkole.Nā pōmaikaʻi o ke ola lōʻihi.
I loko o ke keʻena noiʻi pākaukau o kēia hui, aia kahi pākahi lithium titanate i hoʻāʻo ʻia i ka hoʻāʻo ʻana a me ka hoʻokuʻu ʻana mai ka makahiki 2014. Ua hoʻopiʻi ʻia a hoʻokuʻu ʻia ma mua o 30,000 mau manawa i ʻeono makahiki.
Ma kahi keʻena hana ʻē aʻe, ua hōʻike nā ʻenehana i nā mea hoʻolaha i ka hāʻule, ka kui kui, a me ka ʻoki ʻana i nā hoʻāʻo o nā pākahi lithium titanate.ʻOi loa ma hope o ke komo ʻana o ka nila kila i ka pākaukau, ʻaʻohe ahi a uahi paha, a hiki ke hoʻohana mau ʻia ka pākaukau., ʻo nā pā lithium titanate pū kekahi he ākea ākea o nā mahana ambient.
ʻOiai ua loaʻa i nā pākahi lithium titanate nā pōmaikaʻi o ke ola lōʻihi, palekana kiʻekiʻe, a me ka hoʻouka wikiwiki ʻana, ʻaʻole kiʻekiʻe ka nui o ka ikehu o nā pā lithium titanate, ʻo ka hapalua wale nō o nā pā lithium.No laila, ua noʻonoʻo lākou i nā hiʻohiʻona noiʻi ʻaʻole pono ke kiʻekiʻe o ka ikehu kiʻekiʻe, e like me nā kaʻa kaʻa, nā kaʻa kūikawā, a me nā kikowaena mālama mana.
Ma ke ʻano o ka noiʻi ʻana o ka pākaukau mālama ʻana i ka ikehu a me ka hoʻomohala ʻana a me ka ʻenehana, ua hoʻomaka ka pākaukau sodium-ion i hoʻomohala ʻia e ka Institute of Physics o ka Chinese Academy of Science i ke ala i ke kālepa.Ke hoʻohālikelike ʻia me nā pākiʻi lead-acid, ʻaʻole ʻoi aku ka liʻiliʻi o nā pākahi sodium-ion i ka nui akā ʻoi aku ka māmā o ke kaumaha no ka hiki ke mālama like.ʻO ke kaumaha o nā pāpaʻa sodium-ion o ka leo like ʻoi aku ka liʻiliʻi ma mua o 30% o ka nui o nā pākiʻi lead-acid.Ma kahi kaʻa mākaʻikaʻi uila haʻahaʻa haʻahaʻa, piʻi ka nui o ka uila i mālama ʻia ma ka lumi like ma 60%.
I ka makahiki 2011, ua alakaʻi ʻo Hu Yongsheng, he mea noiʻi ma ka Institute of Physics of the Chinese Academy of Sciences nāna i aʻo ma lalo o Academician Chen Liquan, i alakaʻi i kahi hui a hoʻomaka e hana i ka noiʻi a me ka hoʻomohala ʻana i ka ʻenehana pālolo sodium-ion.Ma hope o 10 mau makahiki o ka noiʻi ʻenehana, ua hoʻomohala ʻia kahi pānaʻi sodium-ion, ʻo ia ka papa lalo o ka noiʻi a me ka hoʻomohala ʻana o ka pā sodium-ion ma Kina a me ka honua.a aia nā kahua noi huahana i ke kūlana alakaʻi.
Ke hoʻohālikelike ʻia me nā pākahi lithium-ion, ʻo kekahi o nā pōmaikaʻi nui loa o nā pāpaʻi sodium-ion ʻo ia ka hoʻolaha ākea a me ka liʻiliʻi.ʻO ka mea maka no ka hana ʻana i nā mea electrode maikaʻi ʻole i holoi ʻia i ka lanahu.ʻO ke kumu kūʻai no ke tona he emi iho ia ma mua o hoʻokahi tausani yuan, ʻoi aku ka haʻahaʻa ma mua o ke kumu kūʻai o nā ʻumi kaukani yuan no ka graphite.ʻO kekahi mea ʻē aʻe, ʻo ka sodium carbonate, he waiwai nui hoʻi i nā kumuwaiwai a me nā mea liʻiliʻi.
ʻAʻole maʻalahi ka puhi ʻana i nā pāpaʻi sodium-ion, palekana maikaʻi, a hiki ke hana ma lalo o 40 degere Celsius.Eia nō naʻe, ʻaʻole maikaʻi ka ikaika o ka ikehu e like me nā pā lithium.I kēia manawa, hiki ke hoʻohana wale ʻia i nā kaʻa uila haʻahaʻa haʻahaʻa, nā kikowaena mālama mālama ikehu a me nā kahua ʻē aʻe e pono ai ka haʻahaʻa haʻahaʻa haʻahaʻa.Eia naʻe, e hoʻohana ʻia ka pahuhopu o nā pākahi sodium-ion ma ke ʻano he mea mālama ikehu, a ua hoʻomohala ʻia kahi ʻōnaehana hoʻopaʻa uila 100-kilowatt-hola.
E pili ana i ka hoʻomohala ʻana i ka wā e hiki mai ana o nā pihi mana a me nā ʻenehu mālama ʻana i ka ikehu, ua manaʻo ʻo Chen Liquan, he mea hoʻonaʻauao o ka Chinese Academy of Engineering, ʻo ka palekana a me ke kumukūʻai ke koi nui no ka noiʻi ʻenehana i nā ʻeke uila a me nā ʻoihana mālama ikehu.I ka nele o ka ikehu kuʻuna, hiki i nā ʻeke waihona ikehu ke hoʻoikaika i ka hoʻohana ʻana i ka ikehu hou ma ka pā, e hoʻomaikaʻi i ka kūʻē ʻana ma waena o ka hoʻohana ʻana i ka mana kiʻekiʻe a me ke awāwa, a hana i kahi ʻōmaʻomaʻo a hoʻomau i ka ikehu.
[Ka nānā ʻana i ka hapalua hola] Ka lanakila ʻana i nā "ʻeha ʻeha" o ka hoʻomohala ʻana i ka ikehu hou
Ma nā ʻōlelo aʻoaʻo a ke aupuni waena e pili ana i ka "14th Five-Year Plan", ua helu ʻia nā kaʻa ikehu hou a me nā kaʻa ikehu hou, me ka ʻenehana ʻike hanauna hou, biotechnology, nā mea kiʻekiʻe kiʻekiʻe, aerospace, a me nā lako kai, ua helu ʻia ma ke ʻano he ʻoihana e kū mai ana. e hooikaikaia.I ka manawa like, ua kuhikuhi ʻia he pono ke kūkulu ʻana i kahi ʻenekini ulu no nā ʻoihana e ulu nei a hoʻoulu i nā ʻenehana hou, nā huahana hou, nā ʻano ʻoihana hou, a me nā hiʻohiʻona hou.
