Isingeniso:
Kule nkathi yanamuhla yokuvikelwa kwemvelo nobuchwepheshe, izimoto zikagesi ziya ngokuya ziduma futhi zizothatha indawo yezimoto zikaphethiloli ezivamile esikhathini esizayo. Iibhethri ye-lithiumiyinhliziyo yemoto kagesi, inikeza amandla adingekayo ukuze imoto kagesi iqhubekele phambili. Impilo yesevisi kanye nokuphepha kwamabhethri emoto kagesi yizindaba ezithinteka kakhulu kubanikazi bezimoto. Nokho, lezi zinkinga ezimbili zihlobene eduze nendlela yokushaja efanele. Amabhethri asetshenziswa ezimotweni zikagesi manje ahlanganisa i-ternary lithium amabhethri namabhethri e-lithium iron phosphate. Imiphi imiphumela ezizoba nayo lezi zindlela ezimbili kulawa mabhethri amabili? Asixoxeni ndawonye.
Umthelela wokusebenzisa bese ushaja amabhethri e-ternary lithium
1. Ukuwohloka kwamandla: Isikhathi ngasinye lapho amandla ebhethri ye-lithium ye-ternary esetshenziswa phezulu abese eshajwa futhi, ukukhishwa okujulile, okungabangela umthamo webhethri le-lithium le-ternary ukuthi libole kancane kancane, isikhathi sokushaja sibe mfushane, kanye nebanga lokushayela linciphe. Isibonelo, othile wenze isilingo. Ngemuva kokuthi ibhethri le-ternary lithium selikhishwe ngokujulile izikhathi eziyi-100, amandla ehla ngo-20% ~ 30% uma kuqhathaniswa nevelu yokuqala. Lokhu kungenxa yokuthi ukukhishwa okujulile kubangela ukulimala kokusebenza kwe-electrode, ukubola kwe-electrolyte, kanye nemvula ye-lithium yensimbi kucekela phansi ukushajwa kwebhethri nokusebenza kokukhipha, okuholela ekwehleni komthamo, futhi lo monakalo awulungiseki.
2. Impilo efinyeziwe: Ukukhipha okujulile kuzosheshisa izinga lokuguga lezinto zangaphakathi zebhethri ye-lithium ye-ternary, kunciphise ukushajwa kwebhethri nokusebenza kokukhipha, kunciphise inani lokushaja komjikelezo nokukhipha, futhi kufinyeze impilo yesevisi.
3. Ukushaja okuncishisiwe kanye nokusebenza kahle kokukhipha: Ukusebenzisa amandla bese ushaja futhi kuzobangela ukuthi ama-electrode aqondile noma angalungile ebhethri ye-lithium ye-ternary ahlukaniseke, kukhuphule ukumelana kwangaphakathi kwebhethri, kunciphise ukusebenza kahle kokushaja, kunwebe isikhathi sokushaja, kunciphise umthamo webhethri, futhi kunciphise ngokuphawulekayo inani lamandla angaphuma.
4. Ukwanda kwezingozi zokuphepha: Ukukhishwa okujulile kwesikhathi eside kungabangela amapuleti angaphakathi we-ternaryibhethri ye-lithiumukukhubazeka noma ukuphuka, okuholela ekujikelezeni okufushane ngaphakathi kwebhethri kanye nobungozi bomlilo nokuqhuma. Ngaphezu kwalokho, ukukhishwa okujulile kwebhethri kwandisa ukumelana kwayo kwangaphakathi, kunciphisa ukusebenza kahle kokushaja, futhi kwandisa ukukhiqizwa kokushisa ngesikhathi sokushaja, okungabangela kalula ibhethri ye-lithium ye-ternary ukuthi iqhume futhi ikhubaze, futhi ibangele nokubaleka okushisayo, ekugcineni kuholele ekuqhumeni nomlilo.
Ibhethri ye-lithium ye-Ternary ibhethri lemoto kagesi elilula futhi eliminyene kakhulu, futhi livame ukusetshenziswa ezimotweni zikagesi ezisezingeni eliphezulu. Ukuze uvimbele imiphumela emibi yokukhishwa okujulile ebhethrini, ibhethri ifakwe ibhodi lokuvikela. Amandla kagesi ebhethri ye-lithium eyodwa eshajwe ngokugcwele angaba ngu-4.2 volts. Uma i-voltage eyodwa ishajwa ifike ku-2.8 volts, ibhodi lokuvikela lizonqamula ukunikezwa kwamandla ngokuzenzakalelayo ukuvimbela ibhethri ekuchithweni kakhulu.
Umthelela wokushaja njengoba uhamba ngamabhethri e-ternary lithium
Ubuhle bokushaja njengoba uhamba ukuthi amandla ebhethri awokushaja okungajulile nokukhipha okungajulile, futhi ahlala egcina izinga eliphezulu lamandla ukugwema imiphumela emibi yamandla aphansi ebhethri. Ngaphezu kwalokho, ukushaja okungajulile nokukhishwa okungajulile nakho kungagcina umsebenzi we-lithium ion ngaphakathi kwe-ternary.ibhethri ye-lithium, yehlisa ngempumelelo ijubane lokuguga lebhethri, futhi iqinisekise ukuthi ibhethri ingakwazi ukukhipha amandla ngokuzinzile phakathi nokusetshenziswa okulandelayo, futhi inganweba nempilo yebhethri. Okokugcina, ukushaja njengoba uhamba kungaqinisekisa ukuthi ibhethri ihlezi isesimweni samandla anele futhi kwenyusa ibanga lokushayela.
Umthelela wokushajwa kabusha ngemuva kokusetshenziswa kumabhethri e-lithium iron phosphate
Ukushaja kabusha ngemva kokusetshenziswa ukukhishwa okujulile, okuzoba nemiphumela emibi esakhiweni sangaphakathi samabhethri e-lithium iron phosphate, okubangela ukulimala kwezinto zangaphakathi zesakhiwo sebhethri, ukusheshisa ukuguga kwebhethri, ukwandisa ukumelana kwangaphakathi, ukunciphisa ukushaja nokukhipha ukusebenza kahle, nokwandisa isikhathi sokushaja. Ngaphezu kwalokho, ngemva kokukhishwa okujulile, ukusabela kwamakhemikhali ebhethri kuyaqina futhi ukushisa kwanda kakhulu. Ukushisa okukhiqizwayo akuhlakazwa ngesikhathi, okungabangela kalula ibhethri ye-lithium iron phosphate ukuthi iqhume futhi igxumeke. Ibhethri eliqhumayo alikwazi ukuqhubeka nokusetshenziswa.
Umthelela wokushaja njengoba uhamba nge-lithium iron phosphate
Ngokusho kokushaja nokukhipha okujwayelekile, amabhethri e-lithium iron phosphate angashajwa futhi ashajwe izikhathi ezingaphezu kwezi-2,000. Uma ukushaja njengoba uhamba njengoba kudingeka kuwukushaja okungajulile nokushajwa okungajulile, impilo yesevisi yamabhethri e-lithium iron phosphate inganwetshwa ngokwezinga eliphezulu. Isibonelo, ibhethri ye-lithium iron phosphate ingashajwa futhi ikhishwe kusuka ku-65% kuya ku-85% wamandla, futhi ukushaja komjikelezo nokuphila kokukhipha kungafinyelela izikhathi ezingaphezu kuka-30,000. Ngoba ukukhipha okungajulile kungagcina ubungqabavu bezinto ezisebenzayo ngaphakathi kwebhethri ye-lithium iron phosphate, kunciphise izinga lokuguga kwebhethri, futhi kunwebe ukuphila kwebhethri kuze kufike ezingeni eliphezulu.
Okubi ukuthi ibhethri ye-lithium iron phosphate ayinakuhambisana kahle. Ukushaja okungashoni kakhulu kanye nokushajwa okungajulile kungabangela iphutha elikhulu kuvoltheji yamaseli ebhethri le-lithium iron phosphate. Ukuqongelela isikhathi eside kuzodala ukuthi ibhethri lonakale ngesikhathi esisodwa. Ukukubeka kalula, kunephutha ku-voltage yebhethri phakathi kweseli ngayinye. Inani lephutha lidlula ibanga elivamile, elizothinta ukusebenza, imayela kanye nempilo yesevisi yalo lonke iphakethe lebhethri.
Isiphetho
Ngokuhlaziya okuqhathanisayo okungenhla, umonakalo odalwe kumabhethri amabili ngokushajwa ngemva kokusetshenziswa kwamandla ebhethri awubuyiseleki emuva, futhi le ndlela ayifaneleki. Ukushaja njengoba usebenzisa kuvumelana nebhethri, kanye nomthelela ongemuhle odalwa yi-ibhethri ye-lithiumincane uma kuqhathaniswa, kodwa akuyona indlela efanele yokushaja. Okulandelayo kwabelana ngendlela elungile yokushaja ukukhulisa ukuphepha kokusetshenziswa kwebhethri nokwelula impilo yesevisi.
1. Gwema ukukhishwa ngokweqile: Uma imitha yamandla emoto kagesi ibonisa ukuthi amandla ebhethri asele angu-20~30%, ngemva kokusebenzisa imoto ehlobo, hamba endaweni yokushaja ukuze uvumele ibhethri liphole imizuzu engu-30 kuya ehoreni ngaphambi kokushajwa, okungagwema izinga lokushisa lokushaja ibhethri ekubeni liphezulu kakhulu, futhi ngesikhathi esifanayo ugweme ukuchithwa kwemiphumela emibi yebhethri ejulile.
2. Gwema ukushaja ngokweqile: Amandla ebhethri asele ngo-20~30%. , Kuthatha cishe amahora angu-8~10 ukushaja ngokugcwele. Kunconywa ukuthi ukunikezwa kwamandla kunganqanyulwa lapho amandla eshajwa ku-90% ngokusho kwesibonisi semitha yamandla, ngoba ukushaja ku-100% kuzokwandisa isizukulwane sokushisa futhi izingozi zokuphepha zizokhuphuka kakhulu, ngakho-ke ukunikezwa kwamandla kunganqanyulwa uma kushajwa ku-90% ukugwema imiphumela emibi yenqubo ebhethri. Amabhethri e-lithium iron phosphate angashajwa aze afike ku-100%, kodwa kufanele kuqashelwe ukuthi ugesi kufanele unqanyulwe ngesikhathi ngemva kokushajwa ngokugcwele ukuze kugwenywe ukushajwa ngokweqile.
