Hajoale, libeteri tsa lithium ion li phethile karolo ea bohlokoa haholo bophelong ba batho, empa ho ntse ho na le mathata a mang a theknoloji ea betri ea lithium. Lebaka le ka sehloohong ke hore electrolyte e sebelisoang ka libeteri tsa lithium ke lithium hexafluorophosphate, e nang le kutloelo-bohloko haholo ho mongobo mme e na le ts'ebetso e phahameng ea mocheso. Lihlahisoa tse sa tsitsang le tse senyehang li senya lisebelisoa tsa electrode, tse bakang ts'ebetso e mpe ea ts'ireletso ea libeteri tsa lithium. Ka nako e ts'oanang, LiPF6 e boetse e na le mathata a kang ho qhibiliha ho fokolang le ho fokotseha ha conductivity libakeng tse tlaase tsa mocheso, tse ke keng tsa kopana le tšebeliso ea matla a betri ea lithium. Ka hona, ho bohlokoa haholo ho hlahisa letsoai le lecha la electrolyte lithium ka ts'ebetso e ntle haholo.
Ho fihlela joale, mekhatlo ea lipatlisiso e hlahisitse mefuta e mengata ea letsoai la electrolyte lithium tse ncha, tse emelang haholoanyane ke lithium tetrafluoroborate le lithium bis-oxalate borate. Har'a tsona, lithium bis-oxalate borate ha e bonolo ho senyeha ka mocheso o phahameng, ha e na kutloelo-bohloko ho mongobo, mokhoa o bonolo oa synthesis, che E na le melemo ea tšilafalo, botsitso ba electrochemical, fensetere e pharaletseng, le bokhoni ba ho theha filimi e ntle ea SEI holim'a holim'a electrode e mpe, empa ho qhibiliha ho tlaase ha electrolyte ho li-solvents tsa carbonate ho lebisa ho conductivity ea eona e tlaase, haholo-holo mocheso oa eona o tlaase. Ka mor'a lipatlisiso, ho ile ha fumanoa hore lithium tetrafluoroborate e na le solubility e kholo ea carbonate solvents ka lebaka la boholo ba eona ba molek'hule e nyenyane, e ka ntlafatsang ka katleho ts'ebetso e tlaase ea mocheso oa libeteri tsa lithium, empa e ke ke ea etsa filimi ea SEI holim'a electrode e mpe. . The electrolyte lithium letsoai lithium difluorooxalate borate, ho ea ka litšobotsi tsa eona tsa sebopeho, lithium difluorooxalate borate e kopanya melemo ea lithium tetrafluoroborate le lithium bis-oxalate borate ka sebopeho le tshebetso, eseng feela ka linear carbonate solvents. Ka nako e ts'oanang, e ka fokotsa viscosity ea electrolyte le ho eketsa conductivity, ka hona ho ntlafatsa ts'ebetso ea mocheso o tlase le tekanyo ea ts'ebetso ea libeteri tsa lithium ion. Lithium difluorooxalate borate e ka boela ea theha lera la thepa ea sebopeho holim'a eleketrode e mpe joalo ka lithium bisoxalate borate. Filimi e ntle ea SEI e kholoanyane.
