Okwangoku, iibhetri ze-lithium ion zidlale indima ebaluleke kakhulu kubomi babantu, kodwa kusekho iingxaki kwitekhnoloji yebhetri ye-lithium.Isizathu esona sizathu kukuba i-electrolyte esetyenziswa kwiibhetri ze-lithium yi-lithium hexafluorophosphate, enomdla kakhulu kumswakama kwaye inomsebenzi ophezulu wokushisa.Ukungazinzi kunye neemveliso zokubola ziyonakalisa izinto ze-electrode, ezibangela ukusebenza kakubi kokhuseleko lweebhetri ze-lithium.Kwangaxeshanye, i-LiPF6 nayo ineengxaki ezifana nokunganyibiliki kakuhle kunye ne-conductivity ephantsi kwiindawo zobushushu obuphantsi, obungenako ukuhlangabezana nokusetyenziswa kweebhetri ze-lithium zamandla.Ke ngoko, kubaluleke kakhulu ukuphuhlisa ityuwa ye-electrolyte lithium entsha ngokusebenza okugqwesileyo.
Ukuza kuthi ga ngoku, amaziko ophando aphuhlise iindidi ezintsha ze-electrolyte lithium salts, abameli abangakumbi yi-lithium tetrafluoroborate kunye ne-lithium bis-oxalate borate.Phakathi kwazo, i-lithium bis-oxalate borate ayilula ukubola kwiqondo lokushisa eliphezulu, ayinamvakalelo kumswakama, inkqubo elula yokudibanisa, akukho Inenzuzo yokungcola, ukuzinza kwe-electrochemical, ifestile ebanzi, kunye nokukwazi ukwenza ifilimu enhle ye-SEI kwi umphezulu we-electrode engalunganga, kodwa ukunyibilika okuphantsi kwe-electrolyte kwizinyibilikisi ze-carbonate ezihambelanayo kukhokelela ekuqhubeni kwayo okuphantsi, ngakumbi ukusebenza kwayo kobushushu obuphantsi.Emva kophando, kwafunyaniswa ukuba i-lithium tetrafluoroborate ine-solubility enkulu kwi-carbonate solvents ngenxa yobungakanani bayo obuncinci be-molecular, obunokuphucula ngokufanelekileyo ukusebenza okuphantsi kobushushu beebhetri ze-lithium, kodwa ayikwazi ukwenza ifilimu ye-SEI kumphezulu we-electrode engalunganga. .I-electrolyte lithium ityuwa i-lithium difluorooxalate borate, ngokweempawu zayo zesakhiwo, i-lithium difluorooxalate borate idibanisa iingenelo ze-lithium tetrafluoroborate kunye ne-lithium bis-oxalate borate kwisakhiwo kunye nokusebenza, kungekhona kuphela kwi-solvents ye-carbonate.Kwangaxeshanye, inokunciphisa i-viscosity ye-electrolyte kwaye yandise i-conductivity, ngaloo ndlela iphucula ngakumbi ukusebenza kobushushu obuphantsi kunye nomgangatho wokusebenza kweebhetri ze-lithium ion.I-Lithium difluorooxalate borate isenokwenza umaleko weempawu zesakhiwo kumphezulu we-electrode engalunganga njenge-lithium bisoxalate borate.Ifilimu ye-SEI elungileyo inkulu.
I-Vinyl sulfate, enye i-non-lithium yetyuwa edityanisiweyo, nayo i-seI ifilimu eyenza ifilimu, enokuthintela ukuhla kwamandla okuqala ebhetri, ukwandisa umthamo wokuqala wokukhupha, ukunciphisa ukwanda kwebhetri emva kokubekwa kwiqondo lokushisa eliphezulu. , kwaye uphucule ukusebenza kokukhutshwa kwebhetri, oko kukuthi, inani lemijikelezo..Ngokwenza oko kwandiswa ukunyamezela okuphezulu kwebhetri kunye nokwandisa ubomi benkonzo yebhetri.Ke ngoko, amathemba ophuhliso lwezongezo ze-electrolyte afumana ingqalelo ngakumbi nangakumbi, kwaye imfuno yentengiso iyanda.
Ngokutsho kwe "Industrial Structure Adjustment Guidance Guidance Catalog (2019 Edition)", izongezo ze-electrolyte zale projekthi zihambelana nenxalenye yokuqala yecandelo lokukhuthaza, iSiqendu 5 (amandla amatsha), inqaku le-16 "uphuhliso kunye nokusetyenziswa kwamandla amatsha eselula. itekhnoloji”, Inqaku le-11 (ishishini lekhemikhali yepetrochemical) inqaku le-12 “izinto ezincamathelayo eziguquliweyo, ezisekwe emanzini kunye nezincamathelisi ezintsha ezinyibilikayo ezishushu, izinto ezifunxa amanzi ngokusingqongileyo, ii-agent zokucocwa kwamanzi, i-molecular sieve solid mercury, i-mercury-free kunye nezinye izinto ezintsha ezisebenzayo nezinobuhlobo nokusingqongileyo. kunye nezongezo, i-nanomaterials, uPhuhliso kunye nokuveliswa kwezixhobo ze-membrane ezisebenzayo, i-ultra-clean kunye ne-high-purity reagents, i-photoresists, i-electronic gases, i-high-performance liquid crystal materials kunye nezinye iikhemikhali ezintsha ezintle;Ngokophononongo kunye nohlalutyo lwamaxwebhu omgaqo-nkqubo welizwe kunye nowengingqi wemizi-mveliso afana ne "Isaziso kuLuhlu olubi lweZikhokelo zoPhuhliso lweBhanti yezoQoqosho (uPhumezo lweSilingo)" (uxwebhu lwe-Ofisi ye-Changjiang No. 89), kunqunywe ukuba le projekthi ayikho iprojekthi ethintelweyo okanye ethintelweyo yophuhliso.
Amandla asetyenziswa xa iprojekthi ifikelela kumandla okuvelisa aquka umbane, umphunga namanzi.Okwangoku, iprojekthi ithatha iteknoloji yemveliso ephucukileyo kunye nezixhobo, kwaye ithatha iindlela ezahlukeneyo zokonga amandla.Emva kokusetyenziswa, zonke izibonakaliso zokusetyenziswa kwamandla ziye zafikelela kwinqanaba eliphezulu kwishishini elifanayo e-China, kwaye zihambelana neenkcukacha zelizwe kunye nezoshishino zokonga umbane, imigangatho yokubeka iliso yokugcina amandla kunye nezixhobo.Umgangatho wokusebenza kwezoqoqosho;okoko nje iprojekthi iphumeza izikhombisi ezahlukeneyo zokusebenzisa amandla, izalathi zokusetyenziswa kwamandla emveliso kunye namanyathelo okugcina amandla acetywayo kule ngxelo ngexesha lokwakha kunye nemveliso, iprojekthi inokwenzeka ngokwembono yokusetyenziswa kwamandla okunengqiqo.Ngokusekelwe koku, kumiselwe ukuba iprojekthi ayibandakanyi ukusetyenziswa kobutyebi kwi-intanethi.
Umlinganiselo woyilo weprojekthi: i-lithium difluorooxalate borate 200t / a, apho i-200t / i-lithium tetrafluoroborate isetyenziswe njengezinto eziluhlaza kwimveliso ye-lithium difluorooxalate ye-borate, ngaphandle komsebenzi we-post-processing, kodwa inokuveliswa njengemveliso egqityiweyo. ngokwahlukeneyo ngokwemfuno yemarike.Vinyl sulfate yi 1000t/a.Jonga kwiTheyibhile 1.1-1
