Amalambu emigwaqweni elangamanje seziphenduke izinsiza eziyinhloko zokukhanyisa imigwaqo yasemadolobheni neyasemaphandleni. Zilula ukuzifaka futhi azidingi izintambo eziningi. Ngokuguqula amandla okukhanya abe amandla kagesi, bese beguqula amandla kagesi abe amandla okukhanya, baletha ucezu lokukhanya ebusuku. Phakathi kwazo, amabhethri aphinde ashajwe nalahlwayo adlala indima ebalulekile.
Uma kuqhathaniswa nebhethri le-asidi eholayo noma ibhethri yejeli esikhathini esidlule, ibhethri ye-lithium evame ukusetshenziswa manje ingcono ngokwamandla athile kanye namandla athile, futhi kulula ukubona ukushaja okusheshayo nokuphuma okujulile, nempilo yalo nayo yinde, ngakho futhi kusilethela isipiliyoni sesibani esingcono.
Nokho, kunomehluko phakathi kokuhle nokubiamabhethri e-lithium. Namuhla, sizoqala ngefomu labo lokupakisha ukuze sibone ukuthi yiziphi izici zalawa mabhethri e-lithium nokuthi iyiphi engcono. Ifomu lokupakisha livame ukuhlanganisa i-cylindrical winding, ukupakisha kwesikwele kanye nokujika kwesikwele.
1. Uhlobo lwe-Cylindrical winding
Okusho ukuthi, ibhethri eyicylindrical, okuwukumiswa kwebhethri yakudala. I-monomer ngokuyinhloko yakhiwe ama-electrode aqondile noma angalungile, ama-diaphragm, abaqoqi abalungile nabangalungile, ama-valve okuphepha, amadivaysi okuvikela ama-overcurrent, izingxenye zokuvikela kanye namagobolondo. Ekuqaleni kwegobolondo, kwakunamagobolondo ensimbi amaningi, futhi manje kunamagobolondo amaningi e-aluminium njengempahla eluhlaza.
Ngokusho kosayizi, ibhethri yamanje ikakhulukazi ihlanganisa i-18650, 14650, 21700 namanye amamodeli. Phakathi kwabo, i-18650 iyona evame kakhulu futhi evuthiwe kakhulu.
2. Uhlobo lwe-square mawinding
Lo mzimba webhethri elilodwa ikakhulukazi wakhiwe ikhava engaphezulu, igobolondo, ipuleti eliphozithivu, ipuleti elinegethivu, i-diaphragm lamination noma i-winging, insulation, izingxenye zokuphepha, njll., futhi yakhelwe ngedivayisi yokuvikela inaliti (NSD) kanye nedivayisi yokuvikela ukuphepha kokushajwa ngokweqile ( OSD). Igobolondo liphinde libe yigobolondo lensimbi ekuqaleni, futhi manje igobolondo le-aluminium seliyiyona ehamba phambili.
3. Isikwele sistakiwe
Okusho ukuthi, ibhethri yephakethe elithambile esivame ukukhuluma ngalo. Isakhiwo esiyisisekelo saleli bhethri sifana nalezi zinhlobo ezimbili ezingenhla zamabhethri, ezakhiwe ngama-electrode aqondile noma angalungile, i-diaphragm, impahla evikelayo, i-electrode lug negobolondo elihle nelibi. Kodwa-ke, ngokungafani nohlobo olumazombezombe, olwakhiwe ngokusonta amapuleti alungile futhi angalungile, ibhethri yohlobo lwe-laminated lakhiwa ngokufaka izingqimba eziningi zamapuleti e-electrode.
Igobolondo ngokuyinhloko ifilimu yepulasitiki ye-aluminium. Ungqimba olungaphandle lwalesi sakhiwo sezinto ezibonakalayo ungqimba lwenayiloni, ungqimba oluphakathi luyi-aluminium foil, ungqimba lwangaphakathi luwungqimba lophawu lokushisa, futhi ungqimba ngalunye luhlanganiswe ne-adhesive. Le nto ine-ductility enhle, eguquguqukayo namandla emishini, futhi inomgoqo omuhle kakhulu nokusebenza kophawu lokushisa, futhi imelana kakhulu nesisombululo se-electrolytic kanye nokugqwala kwe-asidi eqinile.
Kafushane
1) Ibhethri eyi-cylindrical (uhlobo lwama-cylindrical winding) ngokuvamile lenziwa ngegobolondo lensimbi negobolondo le-aluminium. Ubuchwepheshe obuvuthiwe, usayizi omncane, ukuhlanganisa okuvumelana nezimo, izindleko eziphansi, ubuchwepheshe obuvuthiwe nokuvumelana okuhle; Ukukhipha ukushisa ngemva kokuhlanganisa akukuhle ngedizayini, kuyasinda ngesisindo namandla athile aphansi.
2) Ibhethri eliyisikwele (uhlobo oluyisikwele), iningi lawo okwakungamagobolondo ensimbi ekuqaleni, futhi manje sekungamagobolondo e-aluminium. Ukushisa okuhle kokushisa, ukuklama okulula ngamaqembu, ukwethembeka okuhle, ukuphepha okuphezulu, kufaka phakathi i-valve-proof-proof, ubulukhuni obukhulu; Ingenye yezindlela zobuchwepheshe ezijwayelekile ezinezindleko eziphezulu, amamodeli amaningi futhi okunzima ukuhlanganisa izinga lobuchwepheshe.
I-3) Ibhethri yephakethe elithambile (uhlobo lwesikwele se-laminated), nefilimu ye-aluminium-plastic njengephakheji yangaphandle, iguquguqukayo ekushintsheni kosayizi, iphezulu kumandla athile, ilula ngesisindo futhi iphansi ukumelana kwangaphakathi; Amandla emishini ampofu uma kuqhathaniswa, inqubo yokuvala inzima, isakhiwo seqembu siyinkimbinkimbi, ukukhishwa kokushisa akuklanyelwe kahle, akukho mshini wokuvikela ukuqhuma, kulula ukuvuza, ukungaguquguquki kumpofu, futhi izindleko phezulu.
