Ibhethri ye-lithium (i-Li-ion, ibhethri ye-Lithium ion): Amabhethri e-Lithium-ion anezinzuzo zesisindo esilula, umthamo ophezulu, futhi awekho umphumela wenkumbulo, futhi ngaleyo ndlela avame ukusetshenziswa - amadivaysi amaningi edijithali asebenzisa amabhethri e-lithium-ion njengomthombo wamandla, nakuba ebiza kakhulu. Ukuminyana kwamandla amabhethri e-lithium-ion kuphezulu kakhulu, futhi umthamo wawo uphindwe izikhathi ezingu-1.5 kuya kwezingu-2Amabhethri e-NiMHyesisindo esifanayo, futhi inezinga eliphansi kakhulu lokuzikhulula. Ngaphezu kwalokho, amabhethri e-lithium-ion cishe awanawo "umphumela wenkumbulo" futhi awaqukethe izinto ezinobuthi nezinye izinzuzo nazo ziyisizathu esibalulekile sokusetshenziswa kwawo kabanzi. Sicela futhi uqaphele ukuthi amabhethri e-lithium ngokuvamile amakwa ngebhethri ye-lithiumion engu-4.2V noma ibhethri lesibili le-lithium elingu-4.2V noma ibhethri le-lithiumion elingu-4.2V elingashajwa ngaphandle.

18650 lithium ibhethri
I-18650 ingumsunguli webhethri ye-lithium-ion - imodeli yebhethri ye-lithium-ion ejwayelekile ebekwe yinkampani yaseJapan i-SONY ukuze kongiwe izindleko, u-18 usho ububanzi obungu-18mm, u-65 usho ubude obungu-65mm, u-0 usho ibhethri eliyicylindrical. 18650 kusho, 18mm ububanzi, 65mm ubude. Futhi inombolo yemodeli yebhethri engu-5 ingu-14500, 14 mm ububanzi no-50 mm ubude. Ibhethri elijwayelekile le-18650 lisetshenziswa kakhulu embonini, ukusetshenziswa kwezakhamuzi kuncane kakhulu, kuvame ukusetshenziswa kumabhethri aphathekayo namathoshi aphezulu.

Amabhethri ajwayelekile angu-18650 ahlukaniswe amabhethri e-lithium-ion, amabhethri e-lithium iron phosphate. I-voltage yebhethri ye-lithium-ion ye-voltage engu-3.7v yokushaja, i-4.2v yokushaja i-4.2v, i-lithium iron phosphate ibhethri kagesi engu-3.2V, i-voltage yokushaja enqamuliwe engu-3.6v, umthamo uvame ukuba ngu-1200mAh-3350mAh, umthamo ovamile ngu-2200mAh-2600mAh. 18650 ithiyori yempilo yebhethri ye-lithium yokushaja umjikelezo izikhathi eziyi-1000.

Ibhethri le-18650 Li-ion lisetshenziswa kakhulu kumabhethri aphathekayo ngenxa yomthamo walo ophezulu ngeyunithi ngayinye. Ngaphezu kwalokho, ibhethri ye-18650 Li-ion isetshenziswa kabanzi emikhakheni ye-elekthronikhi ngenxa yokuzinza kwayo okuhle kakhulu emsebenzini: evame ukusetshenziswa ku-flashlight yezinga eliphezulu, ukunikezwa kwamandla okuphathekayo, i-wireless data transmitter, izingubo ezifudumele zikagesi nezicathulo, izinsimbi eziphathwayo, imishini yokukhanyisa ephathekayo, iphrinta ephathekayo, izinsimbi zezimboni, izinsimbi zezokwelapha, njll.

Ibhethri le-Li-ion elimakwe ukuthi 3.7V noma 4.2V liyafana. I-3.7V ibhekisela ku-voltage yesikhulumi (okungukuthi, i-voltage evamile) ngesikhathi sokushajwa kwebhethri, kuyilapho ama-volts angu-4.2 ebhekisela kugesi lapho ushaja ishaji egcwele. Ibhethri ye-lithium evamile ekwazi ukushajwa kabusha engu-18650, i-voltage imakwe i-3.6 noma i-3.7v, i-4.2v uma ishajwe ngokugcwele, ehlangene kancane namandla (umthamo), umthamo webhethri we-18650 ojwayelekile ukusuka ku-1800mAh ukuya ku-2600mAh, (18650 amandla webhethri amandla amaningi ku-2600) umthamo webhethri omakiwe kakhulu ngu-2600 3500 noma 4000mAh noma ngaphezulu ayatholakala.

Ngokuvamile kukholakala ukuthi i-voltage engekho yomthwalo webhethri ye-Li-ion izoba ngaphansi kuka-3.0V futhi ugesi uzosetshenziswa phezulu (inani elithile lidinga ukuncika embundwini webhodi lokuvikela ibhethri, isibonelo, liphansi njenge-2.8V, kukhona futhi 3.2V). Amabhethri amaningi e-lithium awakwazi ukushajwa ku-voltage engekho engu-3.2V noma ngaphansi, ngaphandle kwalokho ukukhipha ngokweqile kuzolimaza ibhethri (amabhethri e-lithium emakethe ngokuvamile asetshenziswa ngepuleti lokuvikela, ngakho-ke ukukhishwa ngokweqile kuzoholela epuleti lokuvikela alikwazi ukubona ibhethri, ngaleyo ndlela lingakwazi ukushaja ibhethri). I-4.2V ingumkhawulo omkhulu we-voltage yokushaja ibhethri, ngokuvamile ebhekwa njenge-voltage engalayishwanga yamabhethri e-lithium ashajwa ku-4.2V kugesi Egcwele, inqubo yokushaja ibhethri, i-voltage yebhethri ku-3.7V ikhuphuka kancane iye ku-4.2V, ukushaja kwebhethri ye-lithium akukwazi ukushajwa ngaphezu kuka-4.2V we-no-load ye-voltage ekhethekile ye-lithium, ngaphandle kwalokho izolimaza ibhethri le-lithium.

Izinzuzo

1. Umthamo omkhulu 18650 lithium ibhethri umthamo ngokuvamile phakathi 1200mah ~ 3600mah, kuyilapho umthamo webhethri jikelele mayelana 800mah kuphela, uma kuhlanganiswe zibe 18650 lithium ibhethri pack, ukuthi 18650 lithium ibhethri pack kuyinto ngokungalindelekile kungaba aphule ngokusebenzisa 5000mah.

2. Impilo ende ye-18650 yebhethri ye-lithium yinde kakhulu, ukusetshenziswa okuvamile kokuphila komjikelezo kuze kufike izikhathi ezingu-500, kungaphezu kokuphindwe kabili kwebhethri evamile.

3. Ukusebenza okuphezulu kokuphepha kwe-18650 ukusebenza kokuphepha kwebhethri ye-lithium, ukuze kuvinjelwe isenzakalo sesifunda esifushane sebhethri, i-18650 lithium ibhethri enhle nezigxobo ezimbi zihlukaniswa. Ngakho-ke amathuba okujikeleza okufushane ancishisiwe kakhulu. Ungakwazi ukwengeza ipuleti lokuvikela ukuze ugweme ukushajwa ngokweqile nokukhipha ngokweqile ibhethri, okungase futhi kunwebe impilo yesevisi yebhethri.

4. I-voltage ephezulu engu-18650 i-lithium battery voltage ngokuvamile iku-3.6V, 3.8V kanye ne-4.2V, iphakeme kakhulu kune-voltage engu-1.2V yamabhethri e-NiCd ne-NiMH.

5. Awukho umphumela wenkumbulo Asikho isidingo sokuthulula amandla asele ngaphambi kokushaja, kulula ukuwasebenzisa.

6. Ukumelana okuncane kwangaphakathi: Ukumelana kwangaphakathi kwamaseli e-polymer kuncane kunokwamangqamuzana oketshezi oluvamile, futhi ukumelana kwangaphakathi kwamaseli e-polymer asekhaya kungaba ngaphansi kuka-35mΩ, okunciphisa kakhulu ukuzisebenzisela kwebhethri futhi kwandise isikhathi sokulinda samaselula, futhi kungafinyelela ngokuphelele izinga lezindinganiso zamazwe ngamazwe. Lolu hlobo lwebhethri ye-lithium ye-polymer esekela ukukhishwa okukhulu kwamanje ilungele amamodeli okulawula kude, iba enye indlela ethembisa kakhulu kumabhethri e-NiMH.
