Okwangoku, iibhetri ze-lithium ion zidlale indima ebaluleke kakhulu kubomi babantu, kodwa kusekho iingxaki ezithile kubuchwepheshe bebhetri ye-lithium. Isizathu esiphambili kukuba i-electrolyte esetyenziswa kwiibhetri ze-lithium yi-lithium hexafluorophosphate, ebuthathaka kakhulu kumswakama kwaye isebenza kakuhle kubushushu obuphezulu. Iimveliso zokungazinzi kunye nokubola ziyabola kwizixhobo ze-electrode, nto leyo ebangela ukusebenza kakubi kokhuseleko lweebhetri ze-lithium. Kwangaxeshanye, i-LiPF6 ikwanazo neengxaki ezifana nokunyibilika okubi kunye nokuqhuba okuphantsi kwiindawo ezinobushushu obuphantsi, ezingenakwanelisa ukusetyenziswa kweebhetri ze-lithium ezinamandla. Ke ngoko, kubaluleke kakhulu ukuphuhlisa iityuwa ezintsha ze-lithium ze-electrolyte ezisebenza kakuhle.
Okwangoku, amaziko ophando aphuhlise iintlobo ngeentlobo zeetyuwa ezintsha ze-electrolyte lithium, ezimele ngakumbi yi-lithium tetrafluoroborate kunye ne-lithium bis-oxalate borate. Phakathi kwazo, i-lithium bis-oxalate borate ayilula ukuyibola kubushushu obuphezulu, ayikhathali kumswakama, inkqubo elula yokwenza, hayi. Inezibonelelo zongcoliseko, uzinzo lwe-electrochemical, ifestile ebanzi, kunye nokukwazi ukwenza ifilimu elungileyo ye-SEI kumphezulu we-electrode engalunganga, kodwa ukunyibilika okuphantsi kwe-electrolyte kwi-linear carbonate solvents kukhokelela ekuqhubeni kwayo okuphantsi, ngakumbi ukusebenza kwayo okuphantsi kobushushu. Emva kophando, kwafunyaniswa ukuba i-lithium tetrafluoroborate inokunyibilika okukhulu kwi-carbonate solvents ngenxa yobukhulu bayo obuncinci beemolekyuli, obunokuphucula ngempumelelo ukusebenza okuphantsi kobushushu beebhetri ze-lithium, kodwa ayinakukwazi ukwenza ifilimu ye-SEI kumphezulu we-electrode engalunganga. I-electrolyte lithium salt lithium difluorooxalate borate, ngokweempawu zayo zesakhiwo, i-lithium difluorooxalate borate idibanisa izibonelelo ze-lithium tetrafluoroborate kunye ne-lithium bis-oxalate borate kwisakhiwo kunye nokusebenza, kungekuphela kwi-linear carbonate solvents. Kwangaxeshanye, inokunciphisa i-viscosity ye-electrolyte kwaye yonyuse ukuhanjiswa kwe-conductivity, ngaloo ndlela iphucula ngakumbi ukusebenza kobushushu obuphantsi kunye nokusebenza kwesantya seebhetri ze-lithium ion. I-lithium difluorooxalate borate inokwenza umaleko weempawu zesakhiwo kumphezulu we-electrode engalunganga njenge-lithium bisoxalate borate. Ifilimu elungileyo ye-SEI inkulu.
I-vinyl sulfate, esinye isongezo setyuwa esingeyiyo i-lithium, sikwasisongezo sokwenza ifilimu se-SEI, esinokuthintela ukwehla kwamandla okuqala ebhetri, sonyuse amandla okuqala okukhupha, sinciphise ukwanda kwebhetri emva kokuba ibekwe kubushushu obuphezulu, kwaye siphucule ukusebenza kwebhetri yokukhupha itshaja, oko kukuthi, inani lemijikelo. . Ngaloo ndlela sandisa ukunyamezela okuphezulu kwebhetri kwaye songeze ubomi benkonzo yebhetri. Ke ngoko, amathuba ophuhliso lwezongezo ze-electrolyte afumana ingqwalasela engakumbi, kwaye imfuno yemarike iyanda.
Ngokwe-“Ikhathalogu yeSikhokelo soLungiso lweSicwangciso seShishini (uHlelo luka-2019)”, izongezo ze-electrolyte zale projekthi zihambelana nenxalenye yokuqala yodidi lokukhuthaza, iNqaku lesi-5 (amandla amatsha), inqaku le-16 “uphuhliso nokusetyenziswa kweteknoloji entsha yamandla aphathwayo”, iNqaku le-11 (ishishini leekhemikhali zePetrochemical) inqaku le-12 “izincamathelisi eziguquliweyo, ezisekelwe emanzini kunye nezincamathelisi ezintsha ezishushu ezinyibilikayo, izifunxi zamanzi ezinobuhlobo nokusingqongileyo, iiarhente zonyango lwamanzi, isihluzo semolekyuli i-mercury eqinileyo, ii-catalysts kunye nezinye izithako ezintsha ezisebenzayo nezinobuhlobo nokusingqongileyo, ii-nanomaterials, Uphuhliso kunye nokuveliswa kwezinto ze-membrane ezisebenzayo, ii-reagents ezicocekileyo kakhulu nezicocekileyo kakhulu, ii-photoresists, iigesi ze-elektroniki, izinto zekristale yolwelo ezisebenza kakhulu kunye nezinye iikhemikhali ezintsha ezintle; Ngokwengxelo yokuphononongwa kunye nohlalutyo lwamaxwebhu omgaqo-nkqubo wezemveliso kazwelonke nowengingqi anjenge-“Saziso kwiZikhokelo zoLuhlu oluNgenamda zoPhuhliso lweBelt yoQoqosho (lokuPhunyezwa koVavanyo)” (uXwebhu lweOfisi yaseChangjiang No. 89), kugqitywe kwelokuba le projekthi ayisiyo projekthi yophuhliso ethintelweyo okanye engavumelekanga.
Amandla asetyenziswayo xa iprojekthi ifikelela kumandla emveliso aquka umbane, umphunga kunye namanzi.
