Hona jwale, dibetri tsa lithium ion di bapetse karolo ya bohlokwa maphelong a batho, empa ho ntse ho na le mathata a mang theknolojing ya betri ya lithium. Lebaka le ka sehloohong ke hore electrolyte e sebediswang dibetring tsa lithium ke lithium hexafluorophosphate, e utlwang mongobo haholo mme e na le tshebetso e phahameng ya mocheso. Dihlahiswa tse sa tsitsang le tse bolang di senya thepa ya electrode, e leng se fellang ka tshebetso e mpe ya polokeho ya dibetri tsa lithium. Ka nako e ts'oanang, LiPF6 e boetse e na le mathata a kang ho qhibiliha ho fokolang le ho tsamaisa motlakase ho tlase dibakeng tse tlase tsa mocheso, tse ke keng tsa fihlella tshebediso ya dibetri tsa lithium tse matla. Ka hona, ho bohlokwa haholo ho ntshetsa pele matswai a matjha a electrolyte lithium ka tshebetso e ntle haholo.
Ho fihlela joale, litsi tsa lipatlisiso li thehile mefuta e fapaneng ea letsoai la lithium la electrolyte, tse emelang haholoanyane ke lithium tetrafluoroborate le lithium bis-oxalate borate. Har'a tsona, lithium bis-oxalate borate ha e bonolo ho bola mochesong o phahameng, ha e na kutloelo-bohloko mongobong, mokhoa o bonolo oa ho kopanya, che. E na le melemo ea tšilafalo, botsitso ba electrochemical, fensetere e pharaletseng, le bokhoni ba ho etsa filimi e ntle ea SEI holim'a electrode e mpe, empa ho qhibiliha ho tlase ha electrolyte ho li-solvents tsa linear carbonate ho lebisa ho conductivity ea eona e tlase, haholo-holo ts'ebetso ea eona e tlase ea mocheso. Kamora lipatlisiso, ho fumanoe hore lithium tetrafluoroborate e na le ho qhibiliha ho hoholo ho li-solvents tsa carbonate ka lebaka la boholo ba eona bo bonyenyane ba limolek'hule, e ka ntlafatsang ts'ebetso ea mocheso o tlase oa libeteri tsa lithium, empa e ke ke ea theha filimi ea SEI holim'a electrode e mpe. Electrolyte lithium letsoai lithium difluorooxalate borate, ho latela litšobotsi tsa eona tsa sebopeho, lithium difluorooxalate borate e kopanya melemo ea lithium tetrafluoroborate le lithium bis-oxalate borate sebopehong le ts'ebetsong, eseng feela ho li-solvents tsa linear carbonate. Ka nako e ts'oanang, e ka fokotsa ho teteana ha electrolyte le ho eketsa conductivity, ka hona e ntlafatsa ts'ebetso ea mocheso o tlase le ts'ebetso ea sekhahla sa libeteri tsa lithium ion. Lithium difluorooxalate borate e ka boela ea theha lera la thepa ea sebopeho holim'a electrode e mpe joalo ka lithium bisoxalate borate. Filimi e ntle ea SEI e kholoanyane.
Vinyl sulfate, e 'ngoe ea li-additives tsa letsoai tse seng tsa lithium, le eona ke sehlomathiso sa SEI se etsang filimi, se ka thibelang ho fokotseha ha bokhoni ba pele ba betri, sa eketsa bokhoni ba pele ba ho ntša betri, sa fokotsa katoloso ea betri kamora ho beoa mochesong o phahameng, 'me sa ntlafatsa ts'ebetso ea ho ntša betri ka tjhaja, ke hore, palo ea lipotoloho. . Ka hona, ho atolosa mamello e phahameng ea betri le ho lelefatsa bophelo ba tšebeletso ea betri. Ka hona, menyetla ea nts'etsopele ea li-additives tsa electrolyte e ntse e fumana tlhokomelo e eketsehileng, 'me tlhoko ea' maraka ea eketseha.
