Ni igiki gifise umuyagankuba wa Liquid?
Amazi
(1) Igihimba c’umubiri gifise ubuhinga bwa electrolyte na co nyene citwa umuti w’ivyuma. Ni umuyagankuba ukoreshwa cane mu mabati ya litiyumu - kandi uzwi kandi ko ari - umuyagankuba w’amazi. Ivyo bikoresho vy’amazi vy’ibinyabuzima bigizwe n’umunyu wa litiyumu, umunyu w’ibinyabuzima, n’ibintu vyongereweko.
1 umunyu wa Lithium: ahanini utanga ions zitwara. Lithium hexaroorophosphate ni umunyu wa litiyumu bukoreshwa cane mu mabati y’ubudandaji y’ubudandaji. LiPF6 igororotse ni ikibiriti cera, gishobora gusenyuka mu bikoresho vy’ibinyabuzima nk’ibiyobyabwenge biri hasi -alkyl ethers, nitriles, esters z’ibitoke, ketone, n’inzoga, ariko bishobora gusenyuka cane mu bikoresho vy’ibinyabuzima nk’ibikoko bita alkanes na benzene. LiPF6 electrolyte ifise ubushobozi bwo gutwara ibintu vyinshi cane; ku 20℃, ubushobozi bwo gutwara EC+DMC (igipimo ca 1:1) burashobora gushika kuri 10×10-2S/cm. Ubusanzwe ubuhinga bwo gutwara ibintu bushika ku rugero rwo hejuru iyo uburemere bw’umuyagankuba buri hafi ya 1mol/L. LiPF6 ifise ubushobozi bwo gukoresha ubuhinga bwa electrochemical kandi ntiyongira uwukorakoranya ubu. Ariko rero, LiPF6 irafise ubushuhe bubi kandi irabora bitagoranye mu mazi, isaba kugenzura neza ubukonje bw’ibidukikije mu gihe co kwitegurira no gukoreshwa.
② Ibikoresho vyavyo ni ugusenya umunyu wa litiyumu, bikaba bishobora gutuma umunyu w’umunyu w’i litiyumu ukora.
Ivyo bikoresho bikoreshwa cane ni nk’ivyo bita propylene carbonate, carbonate ya dimethyl, na carbonate y’ivyo kurya.
Ivyo bikoresho vy’ubuhinga bwa none muri rusangi biratorwa kugira ngo bishobore gukoreshwa cane mu buryo bw’umuyagankuba n’uburemere buke. Igipande c’umuyagankuba gihoraho c’ubuhinga bwa none gituma umunyu wa litiyumu woroha gusesa no gusenyura; uburemere buke butuma iyon yihuta cane. Ariko rero, mu vy’ukuri, ibikoresho bifise umuyagankuba munini cane birafise uburemere bwinshi, kandi ibikoresho bifise uburemere buke birafise ubushobozi buke bwo gukoresha umuyagankuba. Ku bw’ivyo, biragoye ko umuntu umwe ashobora gukora ivyo vyose asaba icarimwe ivyo bisabwa. Amabateri ya Lithium - mu bisanzwe akoresha uruvange rw’ibintu bifise ubuzima bifise amashanyarazi menshi n’abafise uburemere buke kugira ngo bashobore gusubiza inyuma ubugoyagoye bw’igice kimwekimwe cose. Nk’akarorero, EC carbonates zifise ibintu vyinshi bihoraho, ivyo bikaba ari ngirakamaro ku bijanye n’ugusenyura umunyu wa litiyumu, mu gihe DMC, DEC, na EMC carbonates zifise uburemere buke, ivyo bikaba bifasha gutuma urugero rw’ukwimuka kw’iyon za litiyumu.
③ Additives: Muri rusangi birafise uruhara mu gutuma umuyagankuba n’umutekano vy’umuyagankuba n’umutekano vy’umuyagankuba. Muri rusangi, ivyongeweko birafise ibikorwa bitatu nyamukuru: aa Guteza imbere ubushobozi bw’uruzitiro rwa SEI, nk’ukwongerako vinylene carbonate (VC), vinyl sulfite (ES), na SO2; b. Gukingira birenze urugero (mu kwongerako biphenyl) n’ivyo hejuru- gukuraho; c. Ivyongeweko bishobora gutuma bateri idashobora guturika canke guturika mu gihe c’ubushuhe burengeye, nk’ugushiramwo ibintu vy’umuriro vy’umuriro, phosphore- ishingiye ku rubeya, n’ibikoresho vy’umuriro vy’urubeya; d. Kugabanya amazi y’urukurikirane n’ibiri muri HF mu gikoresho c’umuyagankuba.
