I kēia manawa, ʻoi aku ka nui o ka hana nui o nā pākahi lithium ion i ke ola o ka poʻe, akā aia kekahi mau pilikia i ka ʻenehana pākahi lithium.ʻO ke kumu nui, ʻo ka electrolyte i hoʻohana ʻia i loko o nā pā lithium he lithium hexafluorophosphate, kahi mea maʻalahi loa i ka makū a loaʻa ka hana wela kiʻekiʻe.ʻO nā huahana inability a me nā decomposition he mea ʻino i nā mea electrode, e hopena i ka hana palekana maikaʻi ʻole o nā pā lithium.I ka manawa like, loaʻa iā LiPF6 nā pilikia e like me ka solubility maikaʻi ʻole a me ka conductivity haʻahaʻa i nā wahi wela haʻahaʻa, ʻaʻole hiki ke hoʻokō i ka hoʻohana ʻana i nā pā lithium mana.No laila, he mea nui loa ka hoʻomohala ʻana i nā paʻakai lithium electrolyte hou me ka hana maikaʻi loa.
I kēia manawa, ua hoʻomohala nā keʻena noiʻi i nā ʻano paʻakai lithium electrolyte hou, ʻo nā mea i hōʻike ʻia he lithium tetrafluoroborate a me ka lithium bis-oxalate borate.I waena o lākou, ʻaʻole maʻalahi ka decompose lithium bis-oxalate borate i ka wela kiʻekiʻe, insensitive i ka makū, ka hana synthesis maʻalahi, ʻaʻole Loaʻa iā ia nā pono o ka pollution, electrochemical stability, ākea pukaaniani, a me ka hiki ke hana i kahi kiʻi SEI maikaʻi ma ka ili o ka electrode maikaʻiʻole, akā, i ka haʻahaʻa solubility o ka electrolyte ma linear carbonate solvents alakai i kona haʻahaʻa conductivity, oi aku kona haʻahaʻa wela hana.Ma hope o ka noiʻi ʻana, ua ʻike ʻia he nui ka solubility lithium tetrafluoroborate i nā solvents carbonate ma muli o kona liʻiliʻi liʻiliʻi, hiki ke hoʻomaikaʻi maikaʻi i ka hana haʻahaʻa haʻahaʻa o nā pā lithium, akā ʻaʻole hiki ke hana i kahi kiʻiʻoniʻoni SEI ma ka ʻili o ka electrode maikaʻi ʻole. .ʻO ka electrolyte lithium salt lithium difluorooxalate borate, e like me kona mau hiʻohiʻona, hoʻohui ka lithium difluorooxalate borate i nā pono o ka lithium tetrafluoroborate a me ka lithium bis-oxalate borate i ka hoʻolālā a me ka hana, ʻaʻole wale i ka linear carbonate solvents.I ka manawa like, hiki iā ia ke hōʻemi i ka viscosity o ka electrolyte a hoʻonui i ka conductivity, a laila e hoʻomaikaʻi hou i ka hana haʻahaʻa haʻahaʻa a me ka hoʻonui ʻana i ka hana o nā pā lithium ion.Hiki i ka Lithium difluorooxalate borate ke hana i kahi papa o nā waiwai hoʻolālā ma ka ʻili o ka electrode maikaʻi ʻole e like me ka lithium bisoxalate borate.ʻOi aku ka nui o kahi kiʻiʻoniʻoni SEI maikaʻi.
ʻO Vinyl sulfate, kekahi mea hoʻohui paʻakai non-lithium, he mea hoʻohui kiʻi ʻoniʻoni SEI hoʻi, hiki ke kāohi i ka emi ʻana o ka mana mua o ka pākaukau, hoʻonui i ka hiki ke hoʻokuʻu mua, hoʻemi i ka hoʻonui ʻana o ka pā ma hope o ka waiho ʻana i ke kiʻekiʻe wela. , a hoʻomaikaʻi i ka hana hoʻokuʻu ʻana o ka pākaukau, ʻo ia hoʻi, ka helu o nā pōʻai..Ma laila e hoʻonui ai i ka hoʻomanawanui kiʻekiʻe o ka pākaukau a hoʻolōʻihi i ke ola lawelawe o ka pā.No laila, ʻoi aku ka nui o ka manaʻo o ka hoʻomohala ʻana o nā mea hoʻohui electrolyte, a ke piʻi nei ka makemake o ka mākeke.
Wahi a ka "Industrial Structure Adjustment Guidance Catalog (2019 Edition)", ua like nā mea hoʻohui electrolyte o kēia papahana me ka ʻāpana mua o ka ʻāpana paipai, Paukū 5 (ka ikehu hou), wahi 16 "hoʻomohala a me ka hoʻohana ʻana i ka ikehu hou mobile. ʻenehana", Paukū 11 (Petrochemical chemical industry) helu 12 "hoʻololi ʻia, nā mea hoʻopili wai-wai a me nā mea hoʻoheheʻe wela hou, nā mea hoʻoheheʻe wai e pili ana i ke kaiapuni, nā mea lapaʻau wai, molecular sieve solid mercury, mercury-free a me nā mea hoʻoheheʻe hou maikaʻi a pili i ke kaiapuni. a me nā mea hoʻohui, nanomaterials, Hoʻomohala a me ka hana ʻana i nā mea membrane hana, ultra-maʻemaʻe a me ka hoʻomaʻemaʻe kiʻekiʻe reagents, photoresists, nā kinoea uila, kiʻekiʻe-hana kiʻekiʻe wai kristal mea a me nā mea hou hou;Wahi a ka loiloi a me ka nānā ʻana i nā palapala kulekele ʻoihana kūloko a me ka ʻāina e like me ka "Notice on the Negative List Guidelines for Economic Belt Development (no Trial Implementation)" (Changjiang Office Document No. 89), ua hoʻoholo ʻia ʻaʻole kēia papahana. he papahana hoʻomohala kapu ʻia a pāpā ʻia paha.
ʻO ka ikehu i hoʻohana ʻia i ka wā e hiki ai ka papahana i ka mana hana e pili ana i ka uila, ka mahu a me ka wai.I kēia manawa, hoʻohana ka papahana i ka ʻenehana hana kiʻekiʻe o ka ʻoihana a me nā mea hana, a lawe i nā ʻano hana hoʻōla ikehu.Ma hope o ka hoʻohana ʻia ʻana, ua hōʻea nā hōʻailona hoʻohana ikehu a pau i ka pae kiʻekiʻe ma ka ʻoihana like ma Kina, a ua kūlike me ka ʻāina a me ka ʻoihana hoʻolālā hoʻolaʻa ikehu hoʻolālā, nā kūlana nānā mālama mālama ikehu a me nā lako.Kūlana hana waiwai;I ka wā e hoʻokō ai ka papahana i nā hōʻailona ikehu like ʻole, nā hōʻailona hoʻohana ikehu huahana a me nā ana hoʻōla ikehu i manaʻo ʻia i loko o kēia hōʻike i ka wā o ke kūkulu ʻana a me ka hana ʻana, hiki ke hana ʻia ka papahana mai ka manaʻo o ka hoʻohana ʻana i ka ikehu noʻonoʻo.Ma muli o kēia, ua hoʻoholo ʻia ʻaʻole pili ka papahana i ka hoʻohana waiwai ma ka laina.
