Yenza ukuhlolwa kokuguga

Manje yonke imikhiqizo yomqondo omusha wamandla wezimoto zamandla amasha namarobhothi anamandla amasha asebenzisa amabhethri e-lithium amasha ukuze akhe amabhethri e-lithium amakhulu. Ngakho-ke yiziphi izicaciso zobuchwepheshe zalawa mabhethri e-lithium? Siyawaqonda osayizi abavame ukusetshenziswa bezihlukanisi zebhethri. I-18650 ingumsunguli wamabhethri e-lithium. Ukuze kongiwe izindleko, i-Sony Corporation yaseJapane yethula ibhethri le-lithium elivamile elinobubanzi obungu-18mm, ubude obungu-65mm, nobude.

Amabhethri ajwayelekile angu-18650 ahlukaniswe amabhethri e-lithium kanye namabhethri e-lithium iron phosphate. I-voltage yebhethri ye-lithium ingu-3.7V, i-voltage yokushaja enqamule ingu-4.2V, i-voltage yegama lebhethri ye-lithium iron phosphate ingu-3.2V, i-voltage yokushaja yokuvala ingu-3.6V, umthamo ojwayelekile ngu-1200mah- 3000mah, futhi umthamo jikelele 2200Mah-2600mah.

Amabhethri e-lithium ayaqonda ukuthi iyini kusihlukanisi sebhethri, manje kuyini ukuguga?

Ukuguga kuyinqubo lapho umkhiqizo ulayishwa futhi usetshenziswe ngaphansi kwezinga lokushisa elithile kanye/noma ukulayishwa. Ngemva kwesikhathi esithile noma umjikelezo, imigomo yokusebenza yomkhiqizo iyafinyelelwa.

Ukuguga kwebhethri ye-lithium ngokuvamile kubhekisela ekujovweni koketshezi ngemva kokuba ibhethri selibekwe kuqala futhi lahlanganiswa, okungaba izinga lokushisa elivamile ukuguga noma izinga lokushisa eliphezulu ukuguga. Inhloso yayo ukuzinzisa ukusebenza nokwakheka kwefilimu ye-SEI eyakhiwe ngemva kokushajwa kokuqala. Izinga lokushisa lekamelo lokuguga lingama-degree angu-25, kanti izinga lokushisa eliphakeme eliguga izitshalo ezahlukene, amanye ama-38 degrees noma ama-45 degrees, isikhathi siphakathi kwamahora angu-48 no-72.

Ukuguga nokuguga kwe-insulation seal:

Mayelana nokuguga okuvulekile kwebhethri, mayelana nokuguga kwezinga lokushisa legumbi, uma umswakama ohlobene ungalawulwa ngaphansi kuka-2%, kungcono ukuwuvala ngemva kokuguga.

Ngokuguga kwezinga lokushisa eliphezulu, umphumela wokuguga wokuvala ungcono.

Kodwa kuqinisekile ukuthi kukhona izinguquko eziguquguqukayo ze-electrochemical phakathi nenqubo yokuguga, ewusizo olukhulu ekuzinzeni kwe-SEI futhi ingakhuthaza ukuzinza kwesistimu ye-electrochemical.

Isimiso nenjongo yokuguga kwe-electrolyte yebhethri ye-lithium ukuthambisa ngokugcwele, kanti enye iwukuthi ezinye izingxenye ezisebenzayo ze-cathode material kumele zingasebenzi ngokuphendula, ukuze ibhethri iyonke isebenze iphephile, izinkampani eziningi. ukuze wenze inqubo isheshe, izinga lokushisa eliphezulu ukuguga , Kodwa izinga lokushisa eliphezulu ukuguga kudinga ukunaka isikhathi sokulawula nokushisa. Ngenxa yokuthi izinga lokushisa eliphezulu ukuguga kungakhiqiza izinto eziphilayo ezidlula izinga lokushisa elivamileUkuguga, umphumela wokulawula ukuwohloka muhle, izithako ezisebenzayo zibonisa ngokugcwele izici zokuphepha zebhethri, ukulawula akukuhle, ukusabela kusabela ngokweqile, ngakho-ke umsebenzi kagesi kuncishisiwe, Umthamo uncishisiwe, i-infrared yintsha, futhi kukhona ithuba lokuvuza

Ngemuva kokuguga kwezinga lokushisa eliphezulu, umsebenzi webhethri uzinzile. Iningi labakhiqizi bebhethri ye-lithium basebenzisa imisebenzi yokuguga yokushisa ephezulu enqubweni yokukhiqiza. Ukuguga ku-45 ~ 50C izinsuku ezingu-1 ~ 3, bese kuba ekamelweni lokushisa. Izenzakalo ezingaba ezingathandeki zizodalulwa ngemva kokuguga kwezinga lokushisa eliphezulu lebhethri: ukushintsha kwamandla kagesi, ukushintsha kogqinsi kanye noshintsho lwangaphakathi lokumelana nezivivinyo eziqondile zokuphepha kwebhethri nokusebenza kwe-electrochemical.

Ukuguga kwezinga lokushisa eliphezulu Ukuze unciphise wonke umjikelezo wokukhiqiza webhethri, abadlali kuphela abangena ebhethri futhi ibhethri kuphela elisheshisa ukusabela kwamakhemikhali ezingeni lokushisa eliphezulu. Ibhethri alisilo ngaphezu kwezinzuzo ezingase zilimaze ibhethri. Isikhathi esingcono kakhulu sokufakwa kwezinga lokushisa kwegumbi singaphezu kwamasonto amathathu, sinegethivu Yebo, lapho ibhalansi phakathi kwegebe ne-electrolyte ihlangabezana nokusabela kwamakhemikhali, ibhethri liyiqiniso.
