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.Umthamo wamandla wamabhethri e-lithium-ion uphakeme kakhulu, futhi umthamo wawo uphindwe izikhathi ezingu-1.5 kuya kwezi-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 enqamule engu-3.6v, umthamo uvame ukuba ngu-1200mAh-3350mAh, umthamo ovamile ingu-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, amathuluzi emboni, amathuluzi ezokwelapha, njll. amathuluzi ezokwelapha, 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 engu-3.6 noma i-3.7v, i-4.2v uma ishajwe ngokugcwele, engahlangene kancane namandla (umthamo), umthamo webhethri we-18650 ojwayelekile ukusuka ku-1800mAh ukuya ku-2600mAh, (umthamo webhethri yamandla angu-18650 iningi lawo liku-2200 ~ 2600mAh), umthamo ojwayelekile umakwe 3500 noma 4000mAh noma ngaphezulu ayatholakala.

Ngokuvamile kukholakala ukuthi i-voltage engalayishi yebhethri ye-Li-ion izoba ngaphansi kuka-3.0V futhi ugesi uzosetshenziswa uphele (inani elithile lidinga ukuncika enanini lomkhawulo webhodi lokuvikela ibhethri, ngokwesibonelo, kukhona ephansi njenge-2.8V, kukhona futhi i-3.2V).Amabhethri amaningi e-lithium awakwazi ukushajwa ku-voltage engalayishi engu-3.2V noma ngaphansi, ngaphandle kwalokho ukukhipha ngokweqile kuzolimaza ibhethri (amabhethri e-lithium emakethe ngokuvamile asetshenziswa nepuleti lokuvikela, ngakho-ke ukukhipha ngokweqile kuzoholela epuleti lokuvikela. ayikwazi ukubona ibhethri, ngaleyo ndlela ayikwazi ukushaja ibhethri).I-4.2V umkhawulo omkhulu wevoltheji yokushaja ibhethri, ngokuvamile ebhekwa njenge-voltage engalayishiwe yamabhethri e-lithium ashajwa ku-4.2V kugesi Egcwele, inqubo yokushaja ibhethri, i-voltage yebhethri ku-3.7V ikhuphuka kancane iye ku-4.2V, i-lithium ukushaja kwebhethri akukwazi ukushajwa ku-voltage engaphezu kuka-4.2V engalayishiwe, ngaphandle kwalokho kuzolimaza nebhethri, okuyindawo ekhethekile yamabhethri e-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 18650 impilo 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 ukuzisebenzisa kwebhethri futhi kwandise isikhathi sokulinda. omakhalekhukhwini, futhi bangafinyelela ngokuphelele ezingeni lamazinga omhlaba.Lolu hlobo lwebhethri ye-lithium ye-polymer esekela ukukhishwa okukhulu kwamanje ilungele amamodeli okulawula kude, iba enye indlela ethembisa kakhulu kumabhethri e-NiMH.
