Njengamanje, amabhethri e-lithium ion adlale indima ebaluleke kakhulu ezimpilweni zabantu, kodwa kusenezinkinga ezithile kubuchwepheshe bebhethri le-lithium. Isizathu esiyinhloko ukuthi i-electrolyte esetshenziswa kumabhethri e-lithium yi-lithium hexafluorophosphate, ezwela kakhulu umswakama futhi isebenza kahle ekushiseni okuphezulu. Imikhiqizo yokungazinzi kanye nokubola iyalimaza izinto ze-electrode, okuholela ekusebenzeni kabi kokuphepha kwamabhethri e-lithium. Ngesikhathi esifanayo, i-LiPF6 nayo inezinkinga ezifana nokuncibilika okubi kanye nokuqhuba okuphansi ezindaweni eziphansi zokushisa, okungenakukwazi ukuhlangabezana nokusetshenziswa kwamabhethri e-lithium anamandla. Ngakho-ke, kubaluleke kakhulu ukuthuthukisa usawoti omusha we-lithium we-electrolyte osebenza kahle kakhulu.
Kuze kube manje, izikhungo zocwaningo zithuthukise izinhlobo ezahlukene zikasawoti omusha we-lithium electrolyte, ezimele kakhulu yi-lithium tetrafluoroborate kanye ne-lithium bis-oxalate borate. Phakathi kwazo, i-lithium bis-oxalate borate akulula ukuyibola ekushiseni okuphezulu, ayizweli kumswakama, inqubo elula yokwenza, cha. Inezinzuzo zokungcola, ukuzinza kwe-electrochemical, ifasitela elibanzi, kanye nekhono lokwenza ifilimu enhle ye-SEI ebusweni be-electrode engemihle, kodwa ukuncibilika okuphansi kwe-electrolyte ezinyibilikeni ze-carbonate eziqondile kuholela ekuqhutshweni kwayo okuphansi, ikakhulukazi ukusebenza kwayo okuphansi kokushisa. Ngemuva kocwaningo, kwatholakala ukuthi i-lithium tetrafluoroborate inokuncibilika okukhulu ezinyibilikeni ze-carbonate ngenxa yobukhulu bayo obuncane bama-molecule, okungathuthukisa ngempumelelo ukusebenza okuphansi kokushisa kwamabhethri e-lithium, kodwa ayikwazi ukwakha ifilimu ye-SEI ebusweni be-electrode engemihle. I-electrolyte lithium salt lithium difluorooxalate borate, ngokwezici zayo zesakhiwo, i-lithium difluorooxalate borate ihlanganisa izinzuzo ze-lithium tetrafluoroborate kanye ne-lithium bis-oxalate borate ngesakhiwo kanye nokusebenza, hhayi kuphela ezinyibilikeni ze-carbonate eziqondile. Ngesikhathi esifanayo, kunganciphisa i-viscosity ye-electrolyte futhi kwandise ukuhanjiswa kwamandla, ngaleyo ndlela kuthuthukise ukusebenza kwezinga lokushisa eliphansi kanye nokusebenza kwesilinganiso samabhethri e-lithium ion. I-lithium difluorooxalate borate ingakha futhi ungqimba lwezakhiwo zesakhiwo ebusweni be-electrode engemihle njenge-lithium bisoxalate borate. Ifilimu enhle ye-SEI inkulu.
I-vinyl sulfate, esinye isithasiselo sikasawoti esingeyona i-lithium, nayo iyisithasiselo esakha ifilimu se-SEI, esingavimbela ukwehla kwamandla okuqala ebhethri, sandise amandla okuqala okukhipha, sinciphise ukwanda kwebhethri ngemva kokufakwa ekushiseni okuphezulu, futhi sithuthukise ukusebenza kwebhethri kokukhipha ishaja, okungukuthi, inani lemijikelezo. . Ngaleyo ndlela sandisa ukukhuthazela okuphezulu kwebhethri futhi sandise impilo yebhethri. Ngakho-ke, amathuba okuthuthukiswa kwezithasiselo ze-electrolyte athola ukunakwa okwengeziwe, futhi isidingo semakethe siyanda.
Ngokusho kwe-“Industrial Structure Adjustment Guidance Catalog (2019 Edition)”, izithasiselo ze-electrolyte zalo msebenzi zihambisana nengxenye yokuqala yesigaba sokukhuthaza, i-Article 5 (amandla amasha), iphuzu 16 “ukuthuthukiswa nokusetshenziswa kobuchwepheshe bamandla amasha obuhambayo”, i-Article 11 (imboni yamakhemikhali kaphethroli) iphuzu 12 “izinti eziguquliwe, ezisekelwe emanzini kanye nezinti ezintsha ezincibilikayo ezishisayo, izinti zamanzi ezinobungani nemvelo, izinto zokwelapha amanzi, isihlungo sama-molecular solid mercury, ama-catalyst kanye nezinye izinti ezintsha ezisebenzayo nezinobungani nemvelo, ama-nanomaterials, Ukuthuthukiswa nokukhiqizwa kwezinto ze-membrane ezisebenzayo, ama-reagent ahlanzekile kakhulu futhi ahlanzekile kakhulu, ama-photoresists, amagesi kagesi, izinto ze-liquid crystal ezisebenza kahle kakhulu kanye namanye amakhemikhali amasha amahle; Ngokusho kokubuyekezwa nokuhlaziywa kwemibhalo yenqubomgomo yezimboni kazwelonke neyendawo efana ne-“Isaziso kuZiqondiso Zohlu Olungalungile Zokuthuthukiswa Kwebhande Lezomnotho (zokuqaliswa Kwesilingo)” (Idokhumenti Yehhovisi LaseChangjiang No. 89), kunqunywa ukuthi lo msebenzi awuyona iphrojekthi yokuthuthukiswa evinjelwe noma evinjelwe.
Amandla asetshenziswa lapho iphrojekthi ifinyelela umthamo wokukhiqiza afaka ugesi, umusi kanye namanzi. Njengamanje, iphrojekthi isebenzisa ubuchwepheshe bokukhiqiza obuthuthukisiwe kanye nemishini, futhi isebenzisa izindlela ezahlukene zokonga amandla. Ngemva kokusetshenziswa, zonke izinkomba zokusetshenziswa kwamandla sezifinyelele ezingeni elithuthukile embonini efanayo eShayina, futhi zihambisana nemininingwane yokuklama yokonga amandla kazwelonke kanye nemboni, amazinga okuqapha okonga amandla kanye nemishini. Izinga lokusebenza kwezomnotho; uma nje iphrojekthi isebenzisa izinkomba ezahlukene zokusebenzisa kahle amandla, izinkomba zokusetshenziswa kwamandla komkhiqizo kanye nezinyathelo zokonga amandla eziphakanyisiwe kulo mbiko ngesikhathi sokwakha nokukhiqiza, iphrojekthi ingenzeka ngokombono wokusetshenziswa kwamandla okunengqondo. Ngokusekelwe kulokhu, kunqunywa ukuthi iphrojekthi ayibandakanyi ukusetshenziswa kwezinsiza ku-inthanethi.
Isikali somklamo sale phrojekthi yilesi: i-lithium difluorooxalate borate 200t/a, lapho i-lithium tetrafluoroborate engu-200t/a isetshenziswa njengezinto zokusetshenziswa zemikhiqizo ye-lithium difluorooxalate borate, ngaphandle komsebenzi wokucubungula ngemuva, kodwa ingakhiqizwa futhi njengomkhiqizo oqediwe ngokwezidingo zemakethe. I-vinyl sulfate ingu-1000t/a. Bheka Ithebula 1.1-1
