Ibhethri le-Lithium (i-Li-ion, ibhethri le-Lithium Ion): Amabhethri e-lithium-ion anezinzuzo zesisindo esilula, amandla aphezulu, kanye nokungasebenzi kahle kwememori, ngakho-ke asetshenziswa kakhulu - amadivayisi amaningi edijithali asebenzisa amabhethri e-lithium-ion njengomthombo wamandla, yize ebiza kakhulu. Ubuningi bamandla amabhethri e-lithium-ion buphakeme kakhulu, futhi amandla awo aphindwe kayi-1.5 kuya ku-2 kunalawoAmabhethri e-NiMHenesisindo esifanayo, futhi inezinga eliphansi kakhulu lokuzikhipha. Ngaphezu kwalokho, amabhethri e-lithium-ion cishe awanawo “umphumela wenkumbulo” futhi awaqukethe izinto ezinobuthi kanti ezinye izinzuzo nazo ziyisizathu esibalulekile sokusetshenziswa kwawo kabanzi. Sicela uqaphele ukuthi amabhethri e-lithium avame ukuphawulwa ngebhethri le-lithium engu-4.2V noma ibhethri lesibili le-lithium engu-4.2V noma ibhethri elishajekayo le-lithium engu-4.2V ngaphandle.

Ibhethri le-lithium elingu-18650
I-18650 ingumsunguli webhethri le-lithium-ion – iyimodeli ejwayelekile yebhethri le-lithium-ion ebekwe yinkampani yaseJapan i-SONY ukuze kongiwe izindleko, i-18 isho ububanzi obungu-18mm, i-65 isho ubude obungu-65mm, i-0 isho ibhethri eliyindilinga. I-18650 isho ububanzi obungu-18mm, ubude obungu-65mm. Futhi inombolo yemodeli yebhethri elingu-No. 5 ingu-14500, ububanzi obungu-14 mm kanye nobude obungu-50 mm. Ibhethri elijwayelekile lika-18650 lisetshenziswa kakhulu embonini, ukusetshenziswa kwabantu abavamile kuncane kakhulu, kuvame ukusetshenziswa kumabhethri e-laptop kanye nezibani eziphezulu.

Amabhethri avamile ka-18650 ahlukaniswe ngamabhethri e-lithium-ion, amabhethri e-lithium iron phosphate. I-voltage yebhethri ye-lithium-ion ye-voltage eqondile engu-3.7v, i-voltage yokunqamula yokushaja engu-4.2v, i-voltage yebhethri ye-lithium iron phosphate engu-3.2V, i-voltage yokunqamula yokushaja engu-3.6v, umthamo uvame ukuba ngu-1200mAh-3350mAh, umthamo ojwayelekile ungu-2200mAh-2600mAh. Ithiyori yokuphila kwebhethri ye-lithium engu-18650 ye-cycle charge izikhathi eziyi-1000.

Ibhethri le-18650 Li-ion lisetshenziswa kakhulu kumabhethri e-laptop ngenxa yomthamo walo ophezulu ngeyunithi ngayinye. Ngaphezu kwalokho, ibhethri le-18650 Li-ion lisetshenziswa kabanzi emikhakheni ye-elekthronikhi ngenxa yokuqina kwalo okuhle emsebenzini: livame ukusetshenziswa kuthoshi lezinga eliphezulu, ugesi oluphathekayo, i-transmitter yedatha engenantambo, izingubo nezicathulo ezifudumele zikagesi, izinsimbi eziphathekayo, imishini yokukhanyisa ephathekayo, iphrinta ephathekayo, izinsimbi zezimboni, izinsimbi zezokwelapha, njll. izinsimbi zezokwelapha, njll.

Ibhethri le-Li-ion eliphawulwe ngo-3.7V noma ngo-4.2V liyafana. I-3.7V ibhekisela ku-voltage yesikhulumi (okungukuthi, i-voltage ejwayelekile) ngesikhathi sokusetshenziswa kokukhishwa kwebhethri, kuyilapho ama-volt angu-4.2 ebhekisela ku-voltage uma ushaja ishaja egcwele. Ibhethri le-lithium elivame ukushajwa kabusha elingu-18650, i-voltage iphawulwe ngo-3.6 noma 3.7v, i-4.2v uma ishajwa ngokugcwele, okungahlobene kangako namandla (umthamo), umthamo webhethri le-18650 ojwayelekile kusukela ku-1800mAh kuya ku-2600mAh, (umthamo webhethri lamandla angu-18650 uvame ukuba ku-2200 ~ 2600mAh), umthamo ojwayelekile uphawulwe ngisho nango-3500 noma 4000mAh noma ngaphezulu.

Ngokuvamile kukholelwa ukuthi i-voltage engenamthwalo yebhethri le-Li-ion izoba ngaphansi kuka-3.0V futhi ugesi uzosetshenziswa phezulu (inani elithile lidinga ukuncika enanini eliphakathi lebhodi lokuvikela ibhethri, isibonelo, ziphansi njengo-2.8V, kukhona no-3.2V). Amabhethri amaningi e-lithium awakwazi ukukhishelwa ku-voltage engenamthwalo engu-3.2V noma ngaphansi, ngaphandle kwalokho ukukhishelwa ngokweqile kuzolimaza ibhethri (amabhethri e-lithium ajwayelekile emakethe asetshenziswa kakhulu nepuleti lokuvikela, ngakho ukukhishelwa ngokweqile kuzoholela ekutheni ipuleti lokuvikela lingakwazi ukubona ibhethri, ngaleyo ndlela lingakwazi ukushaja ibhethri). I-4.2V ingumkhawulo omkhulu we-voltage yokushaja ibhethri, ngokuvamile ibhekwa njenge-voltage engenamthwalo yamabhethri e-lithium ashaja ku-4.2V kugesi. Igcwele, inqubo yokushaja ibhethri, i-voltage yebhethri ku-3.7V ikhuphuka kancane kancane ibe ngu-4.2V, ukushaja ibhethri le-lithium akukwazi ukushaja kube ngaphezu kuka-4.2V i-voltage engenamthwalo, ngaphandle kwalokho kuzolimaza nebhethri, okuyindawo ekhethekile yamabhethri e-lithium.

Izinzuzo

1. Umthamo omkhulu webhethri le-lithium elingu-18650 ngokuvamile uphakathi kuka-1200mah ~ 3600mah, kuyilapho umthamo webhethri ojwayelekile ungaba ngu-800mah kuphela, uma uhlanganiswa nebhethri le-lithium elingu-18650, lelo bhethri le-lithium elingu-18650 lingangena kalula ku-5000mah.

2. Impilo ende Impilo yebhethri le-lithium engu-18650 inde kakhulu, ukusetshenziswa okuvamile kwempilo yomjikelezo kufikela ezikhathini ezingu-500, kungaphezu kokuphindwe kabili kwebhethri elivamile.

3. Ukusebenza kahle kokuphepha kwebhethri le-lithium elingu-18650, ukuze kuvinjelwe isenzakalo se-short circuit yebhethri, kuhlukaniswe izigxobo ze-lithium ezingama-18650 ezinhle nezimbi. Ngakho-ke amathuba e-short circuit ancishisiwe kakhulu. Ungangeza ipuleti lokuvikela ukuze ugweme ukushaja ngokweqile nokuchitha ibhethri ngokweqile, okungandisa nokuphila kwebhethri.

4. I-voltage ephezulu yebhethri le-lithium engu-18650 ngokuvamile ingama-3.6V, 3.8V kanye no-4.2V, iphakeme kakhulu kune-voltage engu-1.2V yamabhethri e-NiCd kanye ne-NiMH.

5. Akukho mphumela wememori Asikho isidingo sokukhipha amandla asele ngaphambi kokushaja, kulula ukuyisebenzisa.

6. Ukumelana okuncane kwangaphakathi: Ukumelana kwangaphakathi kwamaseli e-polymer kuncane kunokwamaseli ajwayelekile oketshezi, kanti ukumelana kwangaphakathi kwamaseli e-polymer asekhaya kungaba ngaphansi kuka-35mΩ, okunciphisa kakhulu ukusetshenziswa kwebhethri futhi kwandise isikhathi sokulinda samaselula, futhi kungafinyelela ngokuphelele ezingeni lezindinganiso zomhlaba wonke. Lolu hlobo lwebhethri le-polymer lithium elisekela ugesi omkhulu lufanele amamodeli okulawula kude, lube yindlela ethembisayo kakhulu yamabhethri e-NiMH.
