Parizvino, mabhatiri e-lithium ion aita basa rinowedzera kukosha muhupenyu hwevanhu, asi pachine mamwe matambudziko mu lithium bhatiri tekinoroji. Chikonzero chikuru ndechekuti electrolyte inoshandiswa mumabhatiri e-lithium inonzi lithium hexafluorophosphate, inonyatsonzwa kunyorova uye ine tembiricha yepamusoro. Kusagadzikana uye kuparara zvigadzirwa zvinosvibisa kune electrode zvinhu, zvichikonzera kusachengeteka kwekuita kwemabhatiri e lithium. Panguva imwecheteyo, LiPF6 inewo matambudziko akadai sekushaya kunyungudika uye yakaderera conductivity munzvimbo dzakaderera tembiricha, izvo zvisingakwanisi kusangana nekushandiswa kwesimba lithium mabhatiri. Naizvozvo, zvakakosha kukudziridza nyowani electrolyte lithium salt ine mashandiro akanaka.
Parizvino, masangano ekutsvagisa akagadzira akasiyana emagetsi matsva e-electrolyte lithium munyu, iyo inomiririra yakawanda inonzi lithium tetrafluoroborate uye lithium bis-oxalate borate. Pakati pavo, lithium bis-oxalate borate haisi nyore kuora pakupisa kwepamusoro, kusanzwa nekunyorova, nyore synthesis process, kwete Iine zvakanakira kusvibiswa, electrochemical kugadzikana, hwindo rakakura, uye kugona kuumba yakanaka SEI firimu pa pamusoro peyakaipa electrode, asi kunyungudika kwakaderera kwe electrolyte mumutsara we carbonate solvents kunotungamirira kune yakaderera conductivity, kunyanya kuderera kwayo kwekushisa. Mushure mekutsvakurudza, zvakaonekwa kuti lithium tetrafluoroborate ine solubility yakakura mu carbonate solvents nekuda kwekukura kwayo kwema molecular size, iyo inogona kubudirira kuvandudza kuderera kwekushisa kwemabhatiri e lithium, asi haigoni kuita SEI firimu pamusoro peiyo negative electrode. . Iyo electrolyte lithium salt lithium difluorooxalate borate, maererano nemaitiro ayo ekugadzirisa, lithium difluorooxalate borate inobatanidza zvakanakira lithium tetrafluoroborate uye lithium bis-oxalate borate mukugadzirisa uye kushanda, kwete chete mumutsara we carbonate solvents. Panguva imwecheteyo, inogona kuderedza viscosity ye electrolyte uye kuwedzera conductivity, nekudaro inowedzera kuvandudza kuderera kwekushisa kwekushanda uye chiyero chekuita kwe lithium ion mabhatiri. Lithium difluorooxalate borate inogona zvakare kuumba dhizaini yezvimiro zvimiro pamusoro peiyo negative electrode se lithium bisoxalate borate. Imwe firimu yakanaka yeSEI yakakura.
Vinyl sulfate, imwe isiri-lithium munyu yekuwedzera, iri zvakare SEI firimu-inogadzira yekuwedzera, iyo inogona kutadzisa kuderera kwekutanga kwebhatiri, kuwedzera kwekutanga kubuda simba, kuderedza kuwedzera kwebhatiri mushure mekuiswa pakupisa kwakanyanya. , uye uvandudze kubhadharisa-kubvisa kushanda kwebheteri, kureva, nhamba yezvikamu. . Nekudaro kuwedzera kushingirira kwebhatiri uye kuwedzera hupenyu hwesevhisi yebhatiri. Naizvozvo, tarisiro yekusimudzira ye electrolyte additives iri kuwedzera kutariswa, uye kudiwa kwemusika kuri kuwedzera.
Zvinoenderana ne "Industrial Structure Adjustment Guidance Guidance Catalog (2019 Edition)", izvo zvinowedzera electrolyte zvepurojekiti iyi zvinoenderana nechikamu chekutanga chechikamu chekukurudzira, Chinyorwa 5 (simba idzva), point 16 "kuvandudza uye kushandiswa kwesimba idzva renhare. tekinoroji ”, Chinyorwa 11 (Petrochemical indasitiri yemakemikari) point 12 “yakagadziridzwa, yakavakirwa mvura-inonamira uye nyowani inopisa inonyunguduka inonyunguduka, ine hushamwari mvura inonwisa, mishonga yekuchenesa mvura, molecular sieve solid mercury, mecury-isina uye zvimwe zvitsva zvinoshanda uye zvine hushamwari zvinokonzeresa. uye additives, nanomaterials, Kuvandudza uye kugadzirwa kwezvinhu zvinoshanda membrane, ultra-yakachena uye yakakwirira-kuchena reagents, photoresists, magetsi magasi, high-performance liquid crystal materials uye mamwe makemikari matsva akanaka; Maererano nekuongorora uye kuongororwa kwemagwaro emitemo yenyika uye yemunharaunda yemabhizimisi akadai se "Chiziviso pamusoro peNhau Dzakashata Dzakarongwa dzeEconomic Belt Development (yeKuitwa Kwekuedza)" (Changjiang Office Document No. 89), zvakatemwa kuti chirongwa ichi hachisi chirongwa chebudiriro chinorambidzwa kana chinorambidzwa.
Simba rinoshandiswa kana chirongwa ichi chasvika pakukwanisa kugadzira rinosanganisira magetsi, chiutsi nemvura. Parizvino, chirongwa ichi chinotora tekinoroji yekugadzirwa kwepamusoro uye michina, uye inotora matanho akasiyana-siyana ekuchengetedza simba. Mushure mekushandiswa, zviratidzo zvese zvekushandiswa kwesimba zvasvika padanho repamusoro muindasitiri imwe chete muChina, uye zvinoenderana nenyika uye indasitiri inochengetedza simba rekugadzira magadzirirwo, masimba ekuchengetedza ekuchengetedza uye michina. Economic operation standard; chero purojekiti ichishandisa zviratidzo zvakasiyana-siyana zvekushandisa simba, zviratidzo zvekushandiswa kwesimba uye matanho ekuchengetedza simba anotsanangurwa mumushumo uyu panguva yekuvaka nekugadzira, chirongwa ichi chinogoneka kubva pakuona kwekushandisa simba zvine musoro. Zvichienderana neizvi, zvinotemerwa kuti chirongwa hachisanganisire zviwanikwa zvekushandisa online.
Chiyero chekugadzira chepurojekiti ndeichi: lithium difluorooxalate borate 200t/a, iyo 200t/a lithium tetrafluoroborate inoshandiswa seyakagadziriswa ye lithium difluorooxalate borate zvigadzirwa, pasina post-processing basa, asi inogona zvakare kugadzirwa seyakapedzwa chigadzirwa. zvakasiyana maererano nezvinodiwa nemusika.
