I le taimi nei, o maa lithium ion ua faʻateleina le sao taua i olaga o tagata, ae o loʻo i ai pea nisi faʻafitauli i tekinolosi maa lithium. O le mafuaaga autu o le electrolyte faʻaaogaina i maa lithium o le lithium hexafluorophosphate, lea e matua maaleale i le susu ma e maualuga le vevela. O mea fa'aletonu ma fa'apalapala e fa'aleagaina i mea fa'aeletise, e mafua ai le le lelei o le saogalemu o ma'a lithium. I le taimi lava e tasi, o loʻo i ai foʻi faʻafitauli o le LiPF6 e pei o le le lelei o le solubility ma le maualalo o le amio i le maualalo o le vevela siosiomaga, e le mafai ona faʻafeiloaʻi le faʻaogaina o le eletise lithium. O le mea lea, e taua tele le atinaʻeina o masima lithium electrolyte fou ma le faʻatinoina lelei.
E oʻo mai i le taimi nei, o faʻalapotopotoga suʻesuʻe ua atiae le tele o masima lithium electrolyte fou, o le tele o sui o le lithium tetrafluoroborate ma le lithium bis-oxalate borate. Faatasi ai ma i latou, o le lithium bis-oxalate borate e le faigofie ona pala i le maualuga o le vevela, le mautonu i le susu, faʻaogaina faigofie, leai E i ai le lelei o le faʻaleagaina, faʻamautu eletise, faamalama lautele, ma le mafai ona fausia se ata lelei SEI i luga o le luga ole electrode le lelei, ae o le solubility maualalo o le electrolyte i linear carbonate solvents taitai atu i lona conductivity maualalo, aemaise lava le faatinoga o le vevela maualalo. Ina ua maeʻa suʻesuʻega, na maua ai o le lithium tetrafluoroborate o loʻo i ai se solubility tele i carbonate solvents ona o lona laʻititi laʻititi, lea e mafai ona faʻaleleia lelei le faʻaogaina o le maualalo o le vevela o maʻa lithium, ae e le mafai ona fausia se ata SEI i luga o le eletise le lelei. . O le electrolyte lithium salt lithium difluorooxalate borate, e tusa ai ma ona uiga faʻavae, lithium difluorooxalate borate e tuʻufaʻatasia le lelei o le lithium tetrafluoroborate ma le lithium bis-oxalate borate i le fausaga ma le faʻatinoga, e le gata i le laina carbonate solvents. I le taimi lava e tasi, e mafai ona faʻaitiitia le viscosity o le electrolyte ma faʻateleina le amio, ma faʻaleleia atili ai le maualalo o le vevela ma le faʻatinoina o le faʻatinoga o maʻa lithium ion. Lithium difluorooxalate borate e mafai foʻi ona fausia se vaega o mea faʻavae i luga ole laiga ole eletise le lelei e pei ole lithium bisoxalate borate. O se ata lelei SEI e sili atu.
Vinyl sulfate, o le isi mea e le o le lithium masima faaopoopo, o se mea faʻapipiʻi ata tifaga SEI, lea e mafai ona faʻalavelaveina le faʻaitiitia o le malosi muamua o le maa, faʻateleina le gafatia muamua, faʻaitiitia le faʻalauteleina o le maa pe a uma ona tuʻuina i le vevela maualuga. , ma faʻaleleia le faʻatinoina o le faʻaogaina o le maa, o lona uiga, le numera o taamilosaga. . O lea e faʻalauteleina ai le maualuga o le tumau o le maʻa ma faʻaumiina ai le ola tautua o le maʻa. O le mea lea, o faʻamoemoega o atinaʻe o mea faʻapipiʻi eletise o loʻo faʻateleina le gauai atu, ma o loʻo faʻateleina le manaʻoga maketi.
E tusa ai ma le "Industrial Structure Adjustment Guidance Catalog (2019 Edition)", o le eletise eletise o lenei poloketi e ogatusa ma le vaega muamua o le vaega faʻamalosia, Mataupu 5 (malosi fou), vaega 16 "atinaʻe ma le faʻaogaina o le malosi fou feaveaʻi. tekinolosi", Mataupu 11 (Petrochemical alamanuia kemikolo) point 12 "suia, pipii faavae vai ma faʻapipiʻi vevela fou liusuavai, vai faauo siʻosiʻomaga, vai togafitiga sooupu, molecular sieve mafiafia mercury, mercury-saoloto ma isi catalysts lelei fou ma le siosiomaga. ma faʻaopoopoga, nanomaterials, Atinaʻe ma le gaosiga o mea faʻaogaina membrane, ultra-mama ma maualuga-mama reagents, photoresists, kasa faaeletonika, maualuga-faatinoga mea tioata vai ma isi vailaʻau lelei fou; E tusa ai ma le iloiloga ma le auʻiliʻiliga o pepa faʻavae a le atunuʻu ma faʻalapotopotoga faʻapitonuʻu e pei o le "Faʻaaliga i luga o le Lisi Leaga Taiala mo le Atinaʻeina o Fuafuaga Tau Tamaoaiga (mo le Faʻataʻitaʻiga Faʻataʻitaʻiga)" (Changjiang Office Document Nu. 89), ua faʻamoemoeina o lenei poloketi e le o. ose galuega fa'atupu fa'asaina pe fa'asa.
O le malosi e fa'aaogaina pe a o'o le poloketi i le gaosiga e aofia ai le eletise, ausa ma le vai. I le taimi nei, o loʻo faʻaaogaina e le poloketi le faʻaogaina o tekonolosi ma meafaigaluega faʻapitoa a le alamanuia, ma faʻaaogaina auala eseese e teu ai le malosi. A maeʻa ona faʻaaogaina, o faʻamatalaga uma o le faʻaaogaina o le malosi ua oʻo i le tulaga maualuga i le pisinisi lava e tasi i Saina, ma o loʻo i ai i laina faʻatasi ma le atunuʻu ma alamanuia faʻataʻitaʻiga faʻasaoina o le malosi, tulaga mataʻituina o le malosi ma meafaigaluega. Tulaga fa'atinoina o le tamaoaiga; A fa'apea lava e fa'atino e le poloketi fa'ailoga eseese o le malosi, fa'ailoga o le fa'aaogaina o le malosi o oloa ma faiga fa'asao malosi o lo'o fa'ata'atia i totonu o lenei lipoti i le taimi o le fausiaina ma le gaosiga, e mafai ona fa'atino le poloketi mai le va'aiga o le fa'aogaina lelei o le malosi. Fa'atatau i lea mea, ua fa'amautu ai o le poloketi e le aofia ai le fa'aogaina o punaoa i luga ole laiga.
Ole fua ole mamanu ole poloketi ole: lithium difluorooxalate borate 200t/a, lea ole 200t/a lithium tetrafluoroborate o loʻo faʻaaogaina e avea ma mea mata mo oloa lithium difluorooxalate borate, e aunoa ma se galuega faʻasolosolo, ae e mafai foi ona gaosia o se oloa maeʻa. eseese e tusa ai ma manaoga maketi.
