Isingeniso:
Enkathini yanamuhla yokuvikelwa kwemvelo kanye nobuchwepheshe, izimoto zikagesi ziya ngokuya zithandwa kakhulu futhi zizothatha indawo yezimoto zikaphethiloli zendabuko esikhathini esizayo.ibhethri le-lithiumiyinhliziyo yemoto kagesi, enikeza amandla adingekayo ukuze imoto kagesi iqhubekele phambili. Impilo yesevisi kanye nokuphepha kwamabhethri ezimoto kagesi yizinkinga ezibaluleke kakhulu kubanikazi bezimoto. Kodwa-ke, lezi zinkinga ezimbili zihlobene kakhulu nendlela efanele yokushaja. Amabhethri asetshenziswa ezimotweni zikagesi manje afaka amabhethri e-lithium e-ternary kanye namabhethri e-lithium iron phosphate. Yimiphi imiphumela ezoba nayo kulezi zindlela ezimbili kula mabhethri amabili? Ake sixoxe ngakho ndawonye.
Umthelela wokusebenzisa amabhethri e-lithium aphelele bese eshaja
1. Ukubola komthamo: Isikhathi ngasinye lapho amandla ebhethri le-ternary lithium esetshenziswa bese eshajwa futhi, kuba ukukhishwa okujulile, okungabangela ukuthi umthamo webhethri le-ternary lithium ubole kancane kancane, isikhathi sokushaja sifushane, kanye nobubanzi bokushayela bunciphe. Isibonelo, othile wenze ucwaningo. Ngemva kokuba ibhethri le-ternary lithium likhishwe ngokujulile izikhathi eziyi-100, umthamo wehla ngo-20% ~ 30% uma kuqhathaniswa nenani lokuqala. Lokhu kungenxa yokuthi ukukhishwa okujulile kubangela umonakalo ezintweni ze-electrode, ukubola kwe-electrolyte, kanye nokushaja kwe-lithium yensimbi kubhubhisa ukusebenza kwebhethri kanye nokusebenza kokukhishwa, okuholela ekunciphiseni kwamandla, futhi lo monakalo awunakuguqulwa.
2. Ukuphila okufushane: Ukukhishwa okujulile kuzosheshisa izinga lokuguga kwezinto zangaphakathi zebhethri le-ternary lithium, kunciphise ukusebenza kokushaja nokukhishwa kwebhethri, kunciphise inani lokushaja nokukhishwa komjikelezo, futhi kufinyeze impilo yesevisi.
3. Ukushaja okuncishisiwe kanye nokusebenza kahle kokukhipha: Ukusebenzisa amandla aphezulu bese uphinda ushaja kuzokwenza ama-electrode amahle nangalungile ebhethri le-lithium eliyi-ternary ahlukane, kwandise ukumelana kwangaphakathi kwebhethri, kunciphise ukusebenza kahle kokushaja, kwandise isikhathi sokushaja, kunciphise amandla ebhethri, futhi kunciphise kakhulu inani lamandla angakhishwa.
4. Izingozi zokuphepha ezengeziwe: Ukukhishwa okujulile kwesikhathi eside kungabangela amapuleti angaphakathi e-ternaryibhethri le-lithiumukukhuhla noma ukuphuka, okuholela ekuqhumeni kwebhethri kanye nengozi yomlilo nokuqhuma. Ngaphezu kwalokho, ukukhishwa kwebhethri okujulile kwandisa ukumelana kwayo kwangaphakathi, kunciphisa ukusebenza kahle kokushaja, futhi kwandisa ukukhiqizwa kokushisa ngesikhathi sokushaja, okungabangela kalula ibhethri le-lithium le-ternary ukuba likhukhumale futhi likhubazeke, futhi kubangele nokubaleka kokushisa, ekugcineni kuholele ekuqhumeni nasekushiseni.
Ibhethri le-lithium eliyi-ternary liyibhethri lemoto kagesi elilula kakhulu nelinamandla kakhulu, futhi livame ukusetshenziswa ezimotweni zikagesi ezisezingeni eliphezulu. Ukuze kuvinjelwe imiphumela emibi yokukhishwa okujulile ebhethrini, ibhethri lifakwe ibhodi lokuvikela. I-voltage yebhethri le-lithium elilodwa eligcwele ngokugcwele ingama-volts angu-4.2. Uma i-voltage eyodwa ikhishwa ibe ngama-volts angu-2.8, ibhodi lokuvikela lizonqamula ngokuzenzakalelayo ukunikezwa kwamandla ukuze kuvinjelwe ibhethri ekukhipheni ngokweqile.
Umthelela wokushaja njengoba uqhubeka namabhethri e-lithium e-ternary
Inzuzo yokushaja njengoba uhamba ukuthi amandla ebhethri angowokushaja okungajulile kanye nokukhishwa okungajulile, futhi ahlala egcina izinga lamandla aphezulu ukuze kugwenywe imiphumela emibi yamandla aphansi ebhethri. Ngaphezu kwalokho, ukushaja okungajulile kanye nokukhishwa okungajulile nakho kungagcina umsebenzi wama-ion e-lithium ngaphakathi kwe-ternary.ibhethri le-lithium, kunciphisa ngempumelelo ijubane lokuguga kwebhethri, futhi uqinisekise ukuthi ibhethri lingakhipha amandla ngokuzinzile ngesikhathi sokusetshenziswa okulandelayo, futhi lingandisa impilo yebhethri. Okokugcina, ukushaja njengoba uhamba kungaqinisekisa ukuthi ibhethri lihlala lisesimweni samandla anele futhi kwandise ububanzi bokushayela.
Umthelela wokushaja kabusha ngemva kokusetshenziswa kumabhethri e-lithium iron phosphate
Ukushaja kabusha ngemva kokusebenzisa kuwukukhipha okujulile, okuzoba nemiphumela emibi esakhiweni sangaphakathi samabhethri e-lithium iron phosphate, okubangela umonakalo ezintweni zokwakha zangaphakathi zebhethri, kusheshiswe ukuguga kwebhethri, kwandise ukumelana kwangaphakathi, kuncishiswe ukusebenza kahle kokushaja nokukhipha, futhi kwandise isikhathi sokushaja. Ngaphezu kwalokho, ngemva kokukhipha okujulile, ukusabela kwamakhemikhali kwebhethri kuyaqina futhi ukushisa kuyanda kakhulu. Ukushisa okukhiqizwayo akunyamalali ngesikhathi, okungabangela kalula ibhethri le-lithium iron phosphate ukuba liqhume futhi liwohloke. Ibhethri eliqhumayo alikwazi ukuqhubeka lisetshenziswa.
Umthelela wokushaja njengoba uqhubeka ne-lithium iron phosphate
Ngokusho kokushaja nokukhipha okuvamile, amabhethri e-lithium iron phosphate angashajwa futhi akhishwe izikhathi ezingaphezu kuka-2,000. Uma ukushaja njengoba kudingeka kungukushaja okungajulile nokukhipha okungajulile, impilo yesevisi yamabhethri e-lithium iron phosphate ingandiswa kuze kufike ezingeni eliphezulu. Isibonelo, ibhethri le-lithium iron phosphate lingashajwa futhi likhishwe kusukela ku-65% kuya ku-85% wamandla, futhi impilo yokushaja nokukhipha umjikelezo ingafinyelela izikhathi ezingaphezu kuka-30,000. Ngoba ukukhishwa okungajulile kungagcina amandla ezinto ezisebenzayo ngaphakathi kwebhethri le-lithium iron phosphate, kunciphise izinga lokuguga kwebhethri, futhi kwandise impilo yebhethri kuze kufike ezingeni eliphezulu.
Ububi ukuthi ibhethri le-lithium iron phosphate alinawo ukuhambisana okuhle. Ukushaja nokukhipha okungajulile njalo kungabangela iphutha elikhulu ku-voltage yamaseli ebhethri le-lithium iron phosphate. Ukuqongelela isikhathi eside kuzokwenza ibhethri lonakale ngesikhathi esisodwa. Kalula nje, kukhona iphutha ku-voltage yebhethri phakathi kweseli ngalinye. Inani lephutha lidlula ububanzi obujwayelekile, okuzothinta ukusebenza, ibanga kanye nokuphila kwesevisi kwephakethe lebhethri lonke.
Isiphetho
Ngokuhlaziywa okuqhathanisayo okungenhla, umonakalo odalwe amabhethri amabili ngokushaja ngemva kokusetshenziswa kwamandla ebhethri awunakuguqulwa, futhi le ndlela ayinconywa. Ukushaja njengoba usebenzisa kunomusa ebhethrini, futhi umthelela omubi odalwe yi-ibhethri le-lithiumincane kakhulu, kodwa akuyona indlela efanele yokushaja. Okulandelayo kwabelana ngendlela efanele yokushaja yokwandisa ukuphepha kokusetshenziswa kwebhethri nokwandisa impilo yesevisi.
1. Gwema ukukhishwa ngokweqile: Uma imitha yamandla emoto kagesi ibonisa ukuthi amandla ebhethri asele ngo-20 ~ 30%, ngemva kokusebenzisa imoto ehlobo, iya endaweni yokushaja ukuze uvumele ibhethri liphole imizuzu engama-30 kuya ehoreni ngaphambi kokushaja, okungagwema izinga lokushisa lokushaja ibhethri ekubeni liphezulu kakhulu, futhi ngesikhathi esifanayo ugweme imiphumela emibi yokukhishwa okujulile ebhethrini.
2. Gwema ukushaja ngokweqile: Amandla ebhethri asele ngo-20~30%. , Kuthatha cishe amahora angu-8~10 ukushaja ngokugcwele. Kunconywa ukuthi ugesi unganqanyulwa uma ugesi ushajwa ufike ku-90% ngokusho kwesibonisi semitha yamandla, ngoba ukushaja ufike ku-100% kuzokwandisa ukukhiqizwa kokushisa futhi izingozi zokuphepha zizokwanda kakhulu, ngakho ugesi unganqanyulwa uma ushajwa ufike ku-90% ukugwema imiphumela emibi yenqubo ebhethrini. Amabhethri e-Lithium iron phosphate angashajwa ufike ku-100%, kodwa kufanele kuqashelwe ukuthi ugesi kufanele unqanyulwe ngesikhathi ngemva kokushajwa uphelele ukuze kugwenywe ukushaja udlulele.
