Tlhahlobo ea mokhoa oa nts’etsopele ea tekheniki ea lithium battery electrolyte
1, electrolyte ea matla a phahameng
Ho lelekisa matla a khethehileng a phahameng ke tataiso e kholo ka ho fetisisa ea lipatlisiso tsa betri ea lithium-ion, haholo-holo ha lisebelisoa tsa mohala li nka boima bo eketsehileng bophelong ba batho, mefuta e mengata, e fetoha ts’ebetso ea bohlokoa ka ho fetisisa ea betri.
2, electrolyte ea mofuta o phahameng oa matla
Hona joale, betri ea lithium-ion ea khoebo e thata ho finyella tekanyo e phahameng ea ho tsoa ka nako e telele, lebaka la bohlokoa ke hore ho futhumatsa ha tsebe ea betri ho teba, ho hanyetsa ka hare ho lebisang mocheso o akaretsang oa betri o phahame haholo, o atisa ho baleha mocheso. . Ka hona, ho electrolyte ho ka thibela betri ho futhumatsa ka potlako haholo ha e ntse e boloka conductivity e phahameng. ‘Me mabapi le matla a betri ea lithium, ho finyella ho tjhaja ka potlako hape ke tataiso ea bohlokoa ea ntlafatso ea electrolyte.
3、 Wide mocheso electrolyte
Betri e na le tšekamelo ea ho senyeha ha electrolyte ka boeona le ho matlafala ha karabelo ea lehlakoreng pakeng tsa lisebelisoa le likarolo tsa electrolyte mocheso o phahameng; ha mocheso o tlase o ka ba le pula ea letsoai ea electrolyte le ho ata ha impedance e mpe ea filimi ea SEI. Seo ho thoeng ke mocheso o pharaletseng oa electrolyte ke ho etsa hore betri e be le sebaka se pharaletseng sa ho sebetsa.
4.Tshireletso electrolyte
Tšireletseho ea betri ke ea bohlokoa ho tukang esita le ho phatloha. Pele ho tsohle, betri ka boeona e ka tuka, kahoo ha betri e fetisitsoe, e tenyetseha kapa e khuts’oane, ha e fumana pinprick ea ka ntle kapa extrusion, ‘me ha mocheso o ka ntle o phahame haholo, o ka baka likotsi tsa ts’ireletso. Ka hona, ho khutlisa lelakabe ke tataiso ea bohlokoa bakeng sa lipatlisiso tsa polokeho ea electrolyte.
5, electrolyte ea mofuta oa nako e telele
Kaha ho sa ntsane ho e-na le mathata a maholo a theknoloji ea ho tsosolosa libeteri tsa lithium-ion, haholo-holo ho tsosolosoa ha matla a matla a lithium, ho ntlafatsa bophelo ba betri ke tsela e ‘ngoe ea ho fokotsa boemo bona. Ho na le mehopolo e ‘meli ea bohlokoa ea lipatlisiso bakeng sa mofuta o molelele oa mofuta oa electrolyte, e’ ngoe ke botsitso ba electrolyte, ho kenyelletsa le botsitso ba mocheso, botsitso ba lik’hemik’hale, botsitso ba motlakase; ea bobeli ke botsitso le lisebelisoa tse ling, tse hlokang ho thehoa ha filimi e tsitsitseng ka li-electrode, ha ho na oxidation e nang le diaphragm, ‘me ha ho na kutu e nang le mokelikeli oa mokelli.
