Kungani amabhethri e-lithium namaphakethe ebhethri e-lithium edinga ukuhlolwa kokuguga nokuguga?

Ukuhlolwa kokuguga kwebhethri ye-lithium:
Isigaba sokwenza kusebenze sephakethe lebhethri le-lithium sihlanganisa ukushajwa kwangaphambili, ukwakheka, ukuguga, kanye nevolumu engaguquki nezinye izigaba. Indima yokuguga iwukwenza izakhiwo nokwakheka kwe-membrane ye-SEI eyakhiwe ngemva kokushaja kokuqala kuzinzile. Ukuguga kwebhethri ye-lithium kuvumela ukungena kwe-electrolyte kube ngcono, okuzuzisa ukuzinza kokusebenza kwebhethri;
Izici eziyinhloko ezithinta ukusebenza kwephakethe lebhethri le-lithium zimbili, okungukuthi izinga lokushisa lokuguga kanye nesikhathi sokuguga. Okubaluleke nakakhulu, ibhethri elisebhokisini lokuhlola ukuguga lisesimeni esivaliwe. Uma ivuliwe ukuze ihlolwe, idatha ehloliwe izohluka kakhulu, futhi idinga ukuqashelwa.
Ukuguga ngokuvamile kubhekisela ekubekweni ngemva kokushajwa kokuqala ngemva kokugcwaliswa kwebhethri. Ingaguga ekamelweni lokushisa noma izinga lokushisa eliphezulu. Indima yayo ukuzinzisa izakhiwo kanye nokwakheka kwe-membrane ye-SEI eyakhiwe ngemva kokushaja kokuqala. Izinga lokushisa lokuguga lingu-25 °C. Ukuguga okunezinga lokushisa eliphezulu kuyahlukahluka kuye ngemboni, okunye kungu-38 °C noma 45 °C. Isikhathi esiningi silawulwa phakathi kwamahora angu-48 nama-72.
Kungani amabhethri e-lithium edinga ukuguga:
1.Indima ukwenza i-electrolyte ingene kangcono, okuzuzisa ukuzinza kokusebenza kwephakethe lebhethri le-lithium;
I-2.Ngemva kokuguga, izinto ezisebenzayo ezintweni ezinhle nezimbi ze-electrode zizosheshisa eminye imiphumela emibi, njengokukhiqizwa kwegesi, ukubola kwe-electrolyte, njll., okungase kuqinise ngokushesha ukusebenza kwe-electrochemical yephakethe lebhethri le-lithium;
3.Khetha ukuvumelana kwephakethe lebhethri le-lithium ngemva kwesikhathi sokuguga. I-voltage yeseli elakhiwe ayizinzile, futhi inani elilinganisiwe lizosuka enanini langempela. I-voltage kanye nokumelana kwangaphakathi kweseli eligugile kuzinzile, okulungele ukukhetha amabhethri anokuvumelana okuphezulu.
Ukusebenza kwebhethri ngemva kokuguga okunezinga lokushisa eliphezulu kuzinzile. Iningi labakhiqizi bebhethri ye-lithium basebenzisa indlela yokusebenza yokuguga esezingeni eliphezulu enqubweni yokukhiqiza, enezinga lokushisa elingu-45 °C - 50 °C izinsuku ezingu-1-3, bese beyiyeka ime ekamelweni lokushisa. Ngemuva kokuguga okunezinga lokushisa eliphezulu, izinto ezimbi ezingaba khona zebhethri zizovezwa, njengokushintsha kwamandla kagesi, izinguquko zogqinsi, izinguquko zangaphakathi zokumelana, njll., ezihlola ngokuqondile ukuphepha nokusebenza kwe-electrochemical kwalawa mabhethri.
Eqinisweni, akukhona ukushaja okusheshayo okusheshisa ngempela ukuguga kwephakethe lebhethri le-lithium, kodwa umkhuba wakho wokushaja! Ukushaja okusheshayo kuzosheshisa ukuguga kwebhethri. Ngokukhula kwenani lokusetshenziswa nesikhathi, ukuguga kwebhethri ye-lithium akunakugwenywa, kodwa indlela enhle yokulungisa inganweba impilo yesevisi yebhethri.
Kungani kudingeka ukuhlolwa kokuguga kwephakethe lebhethri le-lithium?
1.Ngenxa yezizathu ezihlukahlukene ekukhiqizeni ibhethri ye-lithium PACK, ukumelana kwangaphakathi, i-voltage, namandla weseli kuzohluka. Ukuhlanganisa amaseli anomehluko ndawonye ephaketheni lebhethri kuzoveza izinkinga zekhwalithi.
2.Ngaphambi kokuthi kuhlanganiswe iphakethe lebhethri le-lithium, umenzi akayazi idatha yangempela nokusebenza kwephakethe lebhethri ngaphambi kokuguga kwephakethe lebhethri.
3.Ukuhlolwa kokuguga kwephakethe lebhethri ukushaja nokukhipha iphakethe lebhethri ukuhlola inhlanganisela yephakethe lebhethri, ukuhlolwa kokuphila komjikelezo webhethri, ukuhlolwa kwamandla ebhethri. Ukuhlolwa kwesici sokushajwa kwebhethri/ukukhipha, ukushajwa kwebhethri/ukuhlola ukusebenza kahle kokukhipha
4.Izinga lokushajwa ngokweqile/ukukhishwa ngokweqile kokuhlolwa kokuthwala ibhethri
5.Kungemva kokuba imikhiqizo yomkhiqizi seyenziwe izivivinyo zokuguga lapho idatha yangempela yemikhiqizo yaziwa, futhi imikhiqizo enesici ingakhethwa ngesikhathi nangendlela ephumelelayo ukuze kugwenywe ukugeleza ezandleni zabathengi.
6.Ukuze kuvikelwe kangcono amalungelo nezintshisekelo zabathengi, ukuhlolwa kokuguga kwephakethe lebhethri kuyinqubo ebalulekile yawo wonke umkhiqizi.
Sengiphetha, ukuhlolwa kokuguga nokuguga kwamabhethri e-lithium namaphakethe ebhethri ye-lithium kubalulekile. Ayihlobene kuphela nokuzinza kanye nokwenza kahle kokusebenza kwebhethri, kodwa futhi iyisixhumanisi esibalulekile sokuqinisekisa ikhwalithi yomkhiqizo namalungelo omthengi nezintshisekelo. Ngokuqhubeka okuqhubekayo kobuchwepheshe kanye nesidingo esikhulayo sokusebenza kwebhethri, kufanele siqhubeke nokunamathisela ukubaluleka futhi ngokuqhubekayo sithuthukise ubuchwepheshe bokuhlola ukuguga kanye nenqubo yokukhuthaza ukuthuthukiswa okunempilo kwemboni yebhethri ye-lithium futhi sinikeze izixazululo zamandla ezithembekile nezisebenza kahle zezinhlobonhlobo ezihlukahlukene. izicelo. Masijabulele ukunethezeka okulethwe amabhethri e-lithium kuyilapho sinolwazi lokusebenzisa oluvikeleke kakhulu futhi olungcono. Ngokuzayo, sibheke ngabomvu ekuthuthukisweni nasekuthuthukisweni okwengeziwe kule ndawo, okuzofaka amandla aqinile ekuthuthukisweni nasekuqhubekeleni phambili komphakathi.
