I-lithium ion ibhethri electrolyte
Yiziphi izindlela zokulinganisa inani “elincane kancane” lomjovo we-electrolyte wamabhethri e-lithium? Ukusebenza kwamabhethri e-lithium ion kuhlobene kakhulu ne-electrolyte, futhi inani le-electrolyte linomthelela omkhulu ekusebenzeni kwe-electrochemical nokuphepha kwebhethri. Ivolumu efanelekile yomjovo we-electrolyte ayizuzisi kuphela ukukhulisa ukuminyana kwamandla nokunciphisa izindleko, kepha futhi idlala indima ebalulekile ekwenzeni ngcono impilo yomjikelezo wamabhethri e-lithium.
Yiziphi izindlela zokuthola ivolumu yomjovo “omncane kancane” we-electrolyte wamabhethri e-lithium?
Njengoba i-electrolyte izoqhubeka nokuthola uketshezi okwehliswayo kanye nokwehlisa ukusabela kuma-electrode akhombisayo nalawo angavumelekile ngesikhathi sokusebenza kwebhethri le-lithium, ivolumu encane kakhulu yomjovo ilimaza impilo yomjikelezo webhethri le-lithium ion. Ngasikhathi sinye, uma inani le-electrolyte lincane kakhulu, kuzodala nokuthi ezinye izinto ezisebenzayo zingakwazi ukungena, okungahambisani nokuthuthukiswa komthamo webhethri we-lithium. Kodwa-ke, ivolumu yomjovo eningi kakhulu izodala nezinkinga njengokuncipha kwenani lamandla amabhethri e-lithium ion kanye nokwenyuka kwezindleko. Ngakho-ke, ukuthi unganquma kanjani ivolumu yomjovo efanelekile kubalulekile ekusebenzeni nasekusebenzeni kwamabhethri e-lithium. Ibhalansi phakathi kwezindleko ibaluleke kakhulu.
“Kancane kancane, kuncane, futhi kuncane kakhulu” ivolumu yomjovo we-electrolyte wamabhethri e-lithium isitatimende esijwayelekile, futhi asikho isidingo esiqinile. Noma i-electrolyte incane, ibhethri le-lithium selivele lingumkhiqizo onesici. Amaseli ane-electrolyte encane kancane akutholakali kalula. Ngalesi sikhathi, amandla nokuphikiswa kwangaphakathi kwamaseli kujwayelekile. Kunezindlela ezintathu zokuthola ukuthi ibhethri le-lithium line-electrolyte encane kancane. .
1. Khipha ibhethri
Ukuqaqa isivivinyo esonakalisayo futhi yiseli elilodwa kuphela elingahlolwa ngasikhathi. Yize inkinga inganqunywa ngokunembile nangokuqondile, ukusetshenziswa kwangempela kwale ndlela ukuhlola amaseli ngokuyisisekelo akudingekile.
2. Isisindo
Ukunemba kwale ndlela kuphansi, ngoba isiqeshana sepali, ifilimu yeplastiki ye-aluminium, njll izophinde ibe nokwehluka kwesisindo; njengoba i-electrolyte yebhethri ye-lithium “ingaphansi kancane”, khona-ke ukugcinwa kwangempela kweseli ngalinye lebhethri ngeke kwehluke kakhulu. , Ngakho-ke umehluko wesisindo sezinye izinto kungenzeka ube mkhulu kunomehluko wesisindo se-electrolyte.
Vele, ungalazi ngokunembile nangesikhathi esifanele iseli eliyinkinga ngokulinganisa inani liketshezi noma inani liketshezi eligcinwe yiseli ngalinye ngesikhathi sokujova ketshezi, kepha esikhundleni sokukala iseli eligcwele, kungcono ukwandisa ukunemba nokwenza ngcono inqubo ukwelapha izimpawu kanye nembangela.
I-3. Isivivinyo
Lokhu ukugxila kombuzo. Uhlobo luni lwendlela yokuhlola olungasetshenziswa ukuhlola amaseli ane-electrolyte “engaphansi kancane”, okulingana nokuthi hlobo luni lokungajwayelekile oluzokwenzeka kumaseli ane-electrolyte “engaphansi kancane”. Njengamanje, zimbili kuphela izindlela ezaziwayo ukukala amaseli ngomthamo ojwayelekile nokumelana kwangaphakathi, kepha nge-electrolyte engaphansi kancane. Lezi zindlela ezimbili yilezi: umjikelezo, ipulatifomu yokukhipha isilinganiso.
Ngabe unamuphi umphumela ivolumu yomjovo we-electrolyte ekusebenzeni kwamabhethri e-lithium?
InfluenceUmthelela wevolumu ye-electrolyte kumthamo webhethri le-lithium
Umthamo wamabhethri e-lithium uyanda njengoba okuqukethwe kwe-electrolyte kukhuphuka. Umthamo omuhle kakhulu wamabhethri e-lithium ukuthi isihlukanisi sizongena. Kungabonakala ukuthi inani le-electrolyte alanele, ipuleti le-electrode elihle alinamanzi ngokuphelele, futhi isihlukanisi asinamanzi, okuholela ekumelaneni okukhulu kwangaphakathi namandla aphansi. Ukwanda kwe-electrolyte kufanelekile ekusebenziseni ngokugcwele umthamo wento esebenzayo. Lokhu kukhombisa ukuthi umthamo webhethri ye-lithium unobudlelwano obukhulu nenani le-electrolyte. Umthamo wamabhethri e-lithium uyanda ngenani le-electrolyte, kepha ekugcineni kuthanda ukungaguquguquki.
InfluenceIthonya levolumu ye-electrolyte ekusebenzeni komjikelezo webhethri le-lithium
I-electrolyte incane, ukuqhuba kuphansi, futhi ukumelana kwangaphakathi kukhula ngokushesha ngemuva kokuhamba ngebhayisikili. Ukusheshisa ukubola noma i-volatilization ye-electrolyte ngokwengxenye yebhethri le-lithium izinga lapho ukusebenza komjikelezo webhethri kuncipha khona. I-electrolyte eningi kakhulu izoholela ekuphenduleni kohlangothi nokukhuphuka kokukhiqizwa kwegesi, okuholele ekwehleni kokusebenza komjikelezo. Ngaphezu kwalokho, kusetshenziswa i-electrolyte eningi kakhulu. Kungabonakala ukuthi inani le-electrolyte linomthelela omkhulu ekusebenzeni komjikelezo webhethri ye-lithium. I-electrolyte encane kakhulu noma eningi ayihambisani nokusebenza komjikelezo webhethri.
InfluenceIthonya levolumu ye-electrolyte ekusebenzeni kokuphepha kwamabhethri e-lithium
Esinye sezizathu zokuqhuma kwamabhethri e-lithium ukuthi ivolumu yomjovo ayikwazi ukuhlangabezana nezidingo zenqubo. Lapho inani le-electrolyte lincane kakhulu, ukumelana kwangaphakathi kwebhethri kukhulu futhi ukukhiqizwa kokushisa kukhulu. Ukwanda kwezinga lokushisa kuzodala ukuthi i-electrolyte ibole ngokushesha ukuze ikhiqize igesi, bese isihlukanisi sincibilika, okuzobangela ukuthi ibhethri le-lithium livuvuke futhi lifishane-lijikele futhi liqhume. Lapho inani le-electrolyte likhulu kakhulu, inani legesi elenziwa ngesikhathi sokushaja nokukhipha likhulu, ingcindezi yangaphakathi yebhethri inkulu, futhi icala liphukile, okwenza ukuvuza kwe-electrolyte. Lapho izinga lokushisa kwe-electrolyte liphezulu, lizobamba umlilo lapho lihlangabezana nomoya.
I-Electrolyte isetshenziswa njengendawo yokufuduka kwe-lithium ion nokudluliswa kwenkokhiso. Ukuze kuqinisekiswe ukusetshenziswa okugcwele kwezinto ezisetshenziswayo, indawo ngayinye engenalutho yengqikithi yebhethri iyadingeka ukuthi igcwaliswe nge-electrolyte. Ngakho-ke, ivolumu yesikhala sangaphakathi sebhethri nayo ingasetshenziselwa ukucacisa isidingo sebhethri se-electrolyte. ubuningi. Kungabonakala ukuthi inani le-lithium battery electrolyte linomthelela omkhulu ekusebenzeni komjikelezo webhethri. I-electrolyte eningi kakhulu noma encane kakhulu ayihambisani nokusebenza komjikelezo webhethri le-lithium.
