I kēia manawa, ua hoʻokani nā pila lithium ion i kahi kuleana koʻikoʻi i ke ola o kānaka, akā aia nō kekahi mau pilikia i ka ʻenehana pila lithium. ʻO ke kumu nui, ʻo ka electrolyte i hoʻohana ʻia i nā pila lithium he lithium hexafluorophosphate, he mea maʻalahi loa ia i ka makū a he hana wela kiʻekiʻe. ʻO nā huahana instability a me ka decomposition he corrosive i nā mea electrode, e hopena ana i ka hana palekana maikaʻi ʻole o nā pila 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 mahana haʻahaʻa, ʻaʻole hiki ke hoʻokō i ka hoʻohana ʻana i nā pila lithium mana. No laila, he mea nui loa ka hoʻomohala ʻana i nā paʻakai lithium electrolyte hou me ka hana maikaʻi loa.
A hiki i kēia manawa, ua hoʻomohala nā ʻoihana noiʻi i nā ʻano paʻakai lithium electrolyte hou, ʻo nā mea i ʻoi aku ka hōʻike ʻana he lithium tetrafluoroborate a me lithium bis-oxalate borate. I waena o lākou, ʻaʻole maʻalahi ka lithium bis-oxalate borate e palaho i ka mahana kiʻekiʻe, ʻaʻole naʻe i ka makū, hana maʻalahi, ʻaʻohe. Loaʻa iā ia nā pono o ka haumia, ka paʻa electrochemical, ka puka makani ākea, a me ka hiki ke hana i kahi kiʻiʻoniʻoni SEI maikaʻi ma luna o ka electrode maikaʻi ʻole, akā ʻo ka haʻahaʻa o ka solubility o ka electrolyte i loko o nā solvents carbonate linear e alakaʻi ai i kona conductivity haʻahaʻa, ʻoiai kāna hana wela haʻahaʻa. Ma hope o ka noiʻi ʻana, ua ʻike ʻia he nui ka solubility o ka lithium tetrafluoroborate i nā solvents carbonate ma muli o kona liʻiliʻi o ka molekala, hiki ke hoʻomaikaʻi maikaʻi i ka hana haʻahaʻa o nā pila lithium, akā ʻaʻole hiki ke hana i kahi kiʻiʻoniʻoni SEI ma luna o ka electrode maikaʻi ʻole. ʻO ka paʻakai lithium electrolyte lithium difluorooxalate borate, e like me kona ʻano kūkulu, hoʻohui ka lithium difluorooxalate borate i nā pono o ka lithium tetrafluoroborate a me ka lithium bis-oxalate borate i ke ʻano a me ka hana, ʻaʻole wale i nā solvents carbonate linear. I ka manawa like, hiki iā ia ke hoʻemi i ka viscosity o ka electrolyte a hoʻonui i ka conductivity, a laila e hoʻomaikaʻi hou aku i ka hana haʻahaʻa haʻahaʻa a me ka hana wikiwiki o nā pila lithium ion. Hiki i ka lithium difluorooxalate borate ke hana i kahi papa o nā waiwai kūkulu 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, kahi mea hoʻohui paʻakai non-lithium, he mea hoʻohui hana kiʻiʻoniʻoni SEI nō hoʻi, hiki ke kāohi i ka emi ʻana o ka mana mua o ka pila, hoʻonui i ka mana hoʻokuʻu mua, hoʻemi i ka hoʻonui ʻana o ka pila ma hope o ke kau ʻia ʻana i ka mahana kiʻekiʻe, a hoʻomaikaʻi i ka hana hoʻokuʻu-hoʻouka o ka pila, ʻo ia hoʻi, ka helu o nā pōʻaiapuni. . Ma ia mea e hoʻolōʻihi ai i ke ahonui kiʻekiʻe o ka pila a hoʻolōʻihi i ke ola lawelawe o ka pila. No laila, ke loaʻa nei ka nānā nui ʻia i nā manaʻolana hoʻomohala o nā mea hoʻohui electrolyte, a ke piʻi nei ke koi o ka mākeke.
Wahi a ka "Industrial Structure Adjustment Guidance Catalogue (2019 Edition)", ua kūlike nā mea hoʻohui electrolyte o kēia papahana me ka ʻāpana mua o ka māhele hoʻoikaika, ʻAtikala 5 (ikehu hou), kiko 16 "hoʻomohala a me ka hoʻohana ʻana i ka ʻenehana ikehu hou kelepona", ʻAtikala 11 (ʻoihana kemika Petrochemical) kiko 12 "nā mea hoʻopili i hoʻololi ʻia, nā mea hoʻopili wai a me nā mea hoʻopili wela hou, nā mea hoʻomoʻa wai aloha i ke kaiapuni, nā mea mālama wai, ka mercury paʻa sieve molekala, nā mea hoʻouluulu a me nā mea hoʻohui hou a maikaʻi ʻole i ke kaiapuni, nā nanomaterials, Hoʻomohala a me ka hana ʻana i nā mea membrane hana, nā reagents ultra-maʻemaʻe a me ka maʻemaʻe kiʻekiʻe, nā photoresists, nā kinoea uila, nā mea kristal wai hana kiʻekiʻe a me nā kemika maikaʻi hou ʻē aʻe; Wahi a ka loiloi a me ka nānā ʻana o nā palapala kulekele ʻoihana aupuni a me ke kūloko e like me ka "Notice on the Negative List Guidelines for Economic Belt Development (for Trial Implementation)" (Changjiang Office Document No. 89), ua hoʻoholo ʻia ʻaʻole kēia papahana he papahana hoʻomohala i kaupalena ʻia a pāpā ʻia paha.
ʻO ka ikehu i hoʻohana ʻia i ka wā e hiki ai ka papahana i ka hiki ke hana, ʻo ia ka uila, ka mahu a me ka wai. I kēia manawa, ua hoʻohana ka papahana i ka ʻenehana hana holomua a me nā lako hana o ka ʻoihana, a ua hoʻohana i nā ʻano hana mālama ikehu like ʻole. Ma hope o ka hoʻohana ʻia ʻana, ua hiki i nā ʻōkuhi hoʻohana ikehu āpau i ka pae kiʻekiʻe ma ka ʻoihana like ma Kina, a ua kūlike me nā kikoʻī hoʻolālā mālama ikehu aupuni a me ka ʻoihana, nā kūlana nānā mālama ikehu a me nā lako. Kūlana hana hoʻokele waiwai; inā hoʻokō ka papahana i nā ʻōkuhi pono ikehu like ʻole, nā ʻōkuhi hoʻohana ikehu huahana a me nā ana mālama ikehu i hāpai ʻia ma 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 ikehu kūpono. Ma muli o kēia, ua hoʻoholo ʻia ʻaʻole pili ka papahana i ka hoʻohana ʻana i nā kumuwaiwai ma ka pūnaewele.
ʻO ke ana hoʻolālā o ka papahana: lithium difluorooxalate borate 200t/a, nona ka 200t/a lithium tetrafluoroborate i hoʻohana ʻia ma ke ʻano he mea maka no nā huahana lithium difluorooxalate borate, me ka ʻole o ka hana ma hope o ka hana ʻana, akā hiki ke hana ʻia ma ke ʻano he huahana i hoʻopau ʻia ma ke kaʻawale e like me ke koi o ka mākeke. ʻO ka vinyl sulfate he 1000t/a.
