Parizvino, mabhatiri e lithium ion ave kuita basa rakakosha muhupenyu hwevanhu, asi kuchine mamwe matambudziko mu tekinoroji yebhatiri re lithium. Chikonzero chikuru ndechekuti electrolyte inoshandiswa mumabhatiri e lithium i lithium hexafluorophosphate, iyo inonzwa hunyoro zvakanyanya uye ine kushanda kwakanyanya kwekupisa. Zvigadzirwa zvekusagadzikana uye kuora zvinokanganisa zvinhu zve electrode, zvichikonzera kusashanda zvakanaka kwemabhatiri e lithium. Panguva imwe chete, LiPF6 inewo matambudziko akadai sekunyungudika kusina kunaka uye kufambisa mvura kwakaderera munzvimbo dzine tembiricha yakaderera, dzisingakwanise kushandiswa nemabhatiri e lithium ane simba. Saka, zvakakosha zvikuru kugadzira electrolyte lithium salts itsva dzine kushanda kwakanaka.
Kusvika pari zvino, masangano ekutsvagisa akagadzira mhando dzakasiyana dzemunyu mutsva we-electrolyte lithium, idzo dzinonyanya kumiririrwa i-lithium tetrafluoroborate uye lithium bis-oxalate borate. Pakati padzo, lithium bis-oxalate borate haisi nyore kuora kana tembiricha yakakwira, hainzwi hunyoro, maitiro ari nyore ekugadzira, kwete. Ine zvakanakira kusvibiswa, kugadzikana kwemagetsi, hwindo rakafara, uye kugona kugadzira firimu rakanaka reSEI pamusoro peelectrode isina kunaka, asi kunyungudika kushoma kweelectrolyte muzvinyungudutsi zve carbonate zvine mutsara kunotungamira kune conductivity yakaderera, kunyanya kushanda kwayo kwetembiricha yakaderera. Mushure mekutsvagisa, zvakaonekwa kuti lithium tetrafluoroborate ine kunyungudika kukuru muzvinyungudutsi zve carbonate nekuda kwehukuru hwayo hudiki hwemamorekuru, izvo zvinogona kuvandudza mashandiro ematembiricha e lithium asina kupisa zvakanyanya, asi haigone kugadzira firimu reSEI pamusoro peelectrode isina kunaka. Electrolyte lithium salt lithium difluorooxalate borate, zvichienderana nehunhu hwayo hwechimiro, lithium difluorooxalate borate inosanganisa zvakanakira lithium tetrafluoroborate uye lithium bis-oxalate borate muchimiro nekushanda, kwete chete muzvinyungudutsi zve carbonate zvine mutsara. Panguva imwe chete, inogona kuderedza viscosity ye electrolyte uye kuwedzera conductivity, nokudaro ichivandudza kushanda kwekupisa kwakaderera uye kumhanya kwebhatiri re lithium ion. Lithium difluorooxalate borate inogonawo kugadzira jira rehunhu hwechimiro pamusoro pe electrode isina kunaka senge lithium bisoxalate borate. Firimu yakanaka yeSEI yakakura.
Vinyl sulfate, chimwe chinowedzera munyu chisiri lithium, chinowedzerawo kugadzira firimu reSEI, chinogona kudzivirira kudzikira kwesimba rekutanga rebhatiri, kuwedzera simba rekutanga rekuburitsa, kuderedza kuwedzera kwebhatiri mushure mekuiswa pakupisa kwakanyanya, uye kuvandudza mashandiro ebhatiri ekuchaja-kuburitsa, kureva kuti, huwandu hwemasekeji. . Nokudaro kuwedzera kutsungirira kwakanyanya kwebhatiri uye kuwedzera hupenyu hwebasa rebhatiri. Nokudaro, tarisiro yekuvandudzwa kwezvinowedzera zve electrolyte iri kuwedzera kutariswa, uye kudiwa kwemusika kuri kuwedzera.
Sekureva kwe "Industrial Structure Adjustment Guidance Catalog (2019 Edition)", zvinowedzera ma electrolyte zvepurojekiti iyi zvinoenderana nechikamu chekutanga chechikamu chekukurudzira, Chikamu 5 (simba idzva), chikamu 16 "kusimudzira nekushandisa tekinoroji itsva yesimba inofambiswa", Chikamu 11 (Petrochemical chemical industry) chikamu 12 "zvinonamira zvakagadziriswa, zvinobva mumvura uye zvinonamira zvitsva zvinopisa zvinonyunguduka, zvinonamira mvura zvine hushamwari kune nharaunda, zvinorapa mvura, molecular sieve solid mercury, mercury-free nezvimwe zvitsva zvinokatyamadza uye zvinonaka kune nharaunda, nanomaterials, Kugadzira nekugadzira zvinhu zvinoshanda zvemembrane, ma reagents akachena zvakanyanya uye akachena zvakanyanya, ma photoresists, magasi emagetsi, zvinhu zve crystal liquid zvinoshanda zvakanyanya uye mamwe makemikari matsva akanaka; Sekureva kwekuongorora nekuongorora magwaro emitemo yeindasitiri yenyika neyemunharaunda akadai se "Chiziviso paNhungamiro dzeNegative List for Economic Belt Development (yeKuedza Kuitwa)" (Changjiang Office Document Nhamba 89), zvakaonekwa kuti chirongwa ichi hachisi chirongwa chekusimudzira chakarambidzwa kana chakarambidzwa.
Simba rinoshandiswa kana purojekiti yasvika pakukwanisa kwayo kugadzira zvinosanganisira magetsi, utsi nemvura. Parizvino, purojekiti iyi inoshandisa tekinoroji yekugadzira yepamusoro uye michina, uye inoshandisa matanho akasiyana-siyana ekuchengetedza simba. Mushure mekushandiswa, zviratidzo zvese zvekushandisa simba zvasvika padanho repamusoro muindasitiri imwe chete muChina, uye zvinoenderana nezvinodiwa zvekugadzira simba renyika neindasitiri, zviyero zvekutarisa kuchengetedza simba uye michina. Mwero wekushanda kwehupfumi; chero bedzi purojekiti iyi ichishandisa zviratidzo zvakasiyana-siyana zvekushandisa simba zvakanaka, zviratidzo zvekushandisa simba rezvigadzirwa uye matanho ekuchengetedza simba akataurwa mumushumo uyu panguva yekuvaka nekugadzira, purojekiti iyi inogoneka kubva pamaonero ekushandiswa kwesimba zvine musoro. Zvichibva pane izvi, zvakaonekwa kuti purojekiti iyi haisanganisiri kushandiswa kwezviwanikwa online.
