Lan mooy electrolyte electrolyte?
electrolyte bu am doole
(1) composition chimique chimique ñu ngi koy woowe itam solution electrolyte. Ekelyte lithium {2} ion, dafay nekk electrolyte litium {2}on, ñu koy woowe itam electrolyte liquid bu ndoxe. Elektrolite ndoxu organik dafay boole xorom litium, solvant organik, ak yokk.
① xorom Litium: li gëna bari ci ñoom mooy joxe ion yiñ wara jëfandikoo. Hexalfluorophosphate lithium mooy xorom lithium bi gëna bari ci litium-ion. LiPF6 bu sell, kristal bu weex la, di sol ay solvant organik yu melni-alkyl ethers, nitrile, eseur pyridine, ketone, ak alkol, waaye lu bari ci solvant organik yu melni alkane ak bennne. electrolyte LiPF6 amna yoon bu bari; ci 20 degre, yoon wi EC+DMC (soppi volume 1:1) mën yegg ba 10 ×10-2/cm. Doxalin bi dafay faral di dem ba gëna mag su concentration electrolyte bi jege 1mol/L. LiPF6 amna performance electrochimique bu dëgër te du yàq li ñuy jël ci jamono jii. Waaye, LiPF6 amna stabilite termik bu baaxul, te dafay dindi ci ndox, te loolu dafay laaj ñu saytu bu baax ni environmaa bi di doxee ci jamonoy waajal ak jëfandikoo.
② solvant yu organik: Li gëna am solo mooy nga dindi xorom ci litium, loolu mooy tax electrolyte elektoor bi di am ion yiy jël ion yi.
Soldaar yiñ jëfandikoo ci anam wu bari ñooy karbonat propylene, karbonaat dimethyl, ak carbonate diethyl.
Soldaar yu am organik dañu leen di tànnee ngir seen viscosité bu bari dielectric ak seen viskosite bu woyof. Bu gëna bari xorom dielectric dafay tax nga gëna mëna dissolve ak dissociate; viscosité bu gëna ndaw moo jur migraasioŋ ion bu gëna gaaw. Waaye, ci dëgg, solvant yu am constant dielectric yu bari dañu am viskosite bu rëy, te solvant yu am viscosité bu néew, dañu am constant dielectric yu néew. Kon, lu jafe la ci benn solvant ngir mëna matal li ñuy laaj yépp. Lithium {(4}}ion batëri yi dañuy faral di jëfandikoo njaxasu solvant organik yu am constante dielectric yu bari ak ñi am viscosité bu néew ngir faydaal jafe-jafe yi ci kompensaasioŋ bu nekk. Ci misaal, EC carbonates amna constant dielectric yu bari, te loolu dafay am njariñ ci dissociation xorom lithium, waaye DMC, DEC, ak EMC carbonates amnañu viskosite bu néew, loolu dafay gëna yombal limu ion litium yi.
③ yokk: Dañuy faral di def liggéey ngir gëna mëna jëfandikoo kuuraŋ ak kaaraange ci electrolyte bi. Ci anam wu leer, yokk-yëngu yi ñoo am ñatti liggéey yu am solo: aa Yokkatal liggéeyu membrane SEI bi, lu ci melni yokk carbonate vinylene (VC), vinyl sulfite (ES), ak SO2; b. Defal lu ëpp (ci nga yokk biphenyl) ak ci-dasarging; c. Flame retardant yiy yokk mën nañu tere batëri bi lakk wala exploding ci anam yu tàng, lu ci melni yokk retardant yu am halogenatated, phosphorus {7} retardants flame, ak retardant flame composition; d. Wàññil ndoxu trace bi ak HF bi ci electrolyte bi.
