Pakalipano, mabatire a lithiamu-ion atenga gawo lofunikira kwambiri m'miyoyo ya anthu, komabe pali zovuta zina muukadaulo wa batri la lithiamu.Chifukwa chachikulu ndi chakuti electrolyte yomwe imagwiritsidwa ntchito m'mabatire a lithiamu ndi lithiamu hexafluorophosphate, yomwe imakhudzidwa kwambiri ndi chinyezi ndipo imakhala ndi kutentha kwakukulu.Kusakhazikika komanso kuwonongeka kwa zinthu kumawononga zinthu za electrode, zomwe zimapangitsa kuti mabatire a lithiamu asachite bwino.Panthawi imodzimodziyo, LiPF6 imakhalanso ndi mavuto monga kusungunuka kosauka komanso kutsika kwapamwamba m'madera otsika otentha, omwe sangathe kukumana ndi kugwiritsa ntchito mabatire a lithiamu.Chifukwa chake, ndikofunikira kwambiri kupanga mchere watsopano wa electrolyte lithiamu ndikuchita bwino kwambiri.
Pakalipano, mabungwe ofufuza apanga mitundu yambiri ya mchere wa electrolyte lithiamu, omwe amaimira kwambiri lithiamu tetrafluoroborate ndi lithiamu bis-oxalate borate.Pakati pawo, lithiamu bis-oxalate borate si yosavuta kuwola pa kutentha kwambiri, osakhudzidwa ndi chinyezi, njira yosavuta yophatikizira, ayi Imakhala ndi ubwino wa kuipitsidwa, kukhazikika kwa electrochemical, zenera lalikulu, ndikutha kupanga filimu yabwino ya SEI pa pamwamba pa elekitirodi zoipa, koma otsika solubility wa electrolyte mu liniya zosungunulira carbonate kumabweretsa madutsidwe ake otsika, makamaka otsika kutentha ntchito.Pambuyo kafukufuku, anapeza kuti lithiamu tetrafluoroborate ali ndi solubility lalikulu mu carbonate zosungunulira chifukwa yaing'ono maselo kukula, amene angathe bwino kusintha otsika kutentha ntchito ya mabatire lifiyamu, koma sangathe kupanga SEI filimu pamwamba pa elekitirodi zoipa. .Electrolyte lithiamu mchere lithiamu difluorooxalate borate, malinga ndi makhalidwe ake structural, lithiamu difluorooxalate borate limaphatikiza ubwino lithiamu tetrafluoroborate ndi lithiamu bis-oxalate borate kapangidwe ndi ntchito, osati liniya carbonate solvents.Pa nthawi yomweyo, akhoza kuchepetsa mamasukidwe akayendedwe a electrolyte ndi kuonjezera madutsidwe, potero kupititsa patsogolo otsika kutentha ntchito ndi mlingo ntchito ya lithiamu ion mabatire.Lithium difluorooxalate borate imathanso kupanga wosanjikiza wazinthu zamapangidwe pamwamba pa electrode yoyipa ngati lithiamu bisoxalate borate.Kanema wabwino wa SEI ndi wamkulu.
Vinyl sulfate, chowonjezera china chosakhala cha lithiamu mchere, ndi chowonjezera chopanga filimu cha SEI, chomwe chingalepheretse kuchepa kwa mphamvu ya batire, kuwonjezera mphamvu yotulutsa koyamba, kuchepetsa kukulitsa kwa batire pambuyo poyikidwa pa kutentha kwakukulu. , ndikuwongolera magwiridwe antchito a batire, ndiye kuti, kuchuluka kwa ma cycle..Potero kukulitsa kupirira kwakukulu kwa batri ndikutalikitsa moyo wautumiki wa batri.Chifukwa chake, chiyembekezo cha chitukuko cha zowonjezera ma electrolyte chikuchulukirachulukira, ndipo kufunikira kwa msika kukukulirakulira.
Malinga ndi "Industrial Structure Adjustment Guidance Catalog (2019 Edition)", zowonjezera za electrolyte za polojekitiyi zikugwirizana ndi gawo loyamba la gulu lolimbikitsa, Gawo 5 (mphamvu zatsopano), mfundo 16 "kukula ndi kugwiritsa ntchito mphamvu zatsopano zam'manja. tekinoloje ", Article 11 (Petrochemical Chemical industry) point 12 "zomatira zosinthidwa, zokhala ndi madzi ndi zomatira zatsopano zotentha zotentha, zothira madzi ochezeka, zothira madzi, ma molekyulu a sieve olimba mercury, opanda mercury ndi zina zatsopano zothandiza komanso zoteteza chilengedwe. ndi zowonjezera, nanomaterials, Kupititsa patsogolo ndi kupanga zida zogwirira ntchito za membrane, ma reagents oyeretsedwa kwambiri komanso oyeretsedwa kwambiri, ma photoresists, mpweya wamagetsi, zida zamadzimadzi zamadzimadzi zogwira ntchito kwambiri ndi mankhwala ena atsopano abwino;Malinga ndi kuwunika ndi kusanthula zikalata za malamulo a dziko ndi a m'dera la mafakitale monga "Chidziwitso pa Mndandanda Woipa Malangizo a Economic Belt Development (poyesa Kuyesa)" (Changjiang Office Document No. 89), zatsimikiziridwa kuti ntchitoyi siili pulojekiti yachitukuko yoletsedwa kapena yoletsedwa.
Mphamvu zomwe zimagwiritsidwa ntchito pulojekiti ikafika popanga mphamvu zimaphatikizapo magetsi, nthunzi ndi madzi.Pakalipano, polojekitiyi imagwiritsa ntchito zipangizo zamakono zopangira mafakitale ndi zipangizo, ndipo imagwiritsa ntchito njira zosiyanasiyana zopulumutsira mphamvu.Pambuyo pogwiritsidwa ntchito, zizindikiro zonse zogwiritsira ntchito mphamvu zafika pamlingo wapamwamba kwambiri pamakampani omwewo ku China, ndipo zimagwirizana ndi ndondomeko ya mapangidwe a dziko ndi mafakitale, miyezo yowunikira mphamvu yopulumutsa mphamvu ndi zipangizo.Economic ntchito muyezo;malinga ngati polojekitiyo ikugwiritsira ntchito zizindikiro zosiyanasiyana zogwiritsira ntchito mphamvu zamagetsi, zizindikiro zogwiritsira ntchito mphamvu zamagetsi ndi njira zopulumutsira mphamvu zomwe zaperekedwa mu lipotili panthawi yomanga ndi kupanga, polojekitiyi ndi yotheka chifukwa cha kugwiritsa ntchito mphamvu moyenera.Kutengera izi, zatsimikiziridwa kuti pulojekitiyi siyikuphatikiza kugwiritsa ntchito zinthu pa intaneti.
Mapangidwe a polojekitiyi ndi: lithiamu difluorooxalate borate 200t/a, yomwe 200t/a lithiamu tetrafluoroborate imagwiritsidwa ntchito ngati zopangira za lithiamu difluorooxalate borate, popanda kukonzanso ntchito, koma imatha kupangidwanso ngati chomaliza. mosiyana malinga ndi kufunikira kwa msika.Vinyl sulphate ndi 1000t/a.Onani Table 1.1-1
