Ibhethri ye-lithium engu-18650 ibhethri elisetshenziswa kakhulu emikhiqizweni ye-elekthronikhi njengama-laptops, ama-smartphone, nezimoto zikagesi.Ngokukhula kwesidingo somhlaba wonke sokuvikelwa kwemvelo, ukongiwa kwamandla namandla asebenzayo, amathemba emakethe amabhethri e-lithium angu-18650 abanzi kakhulu.
Okokuqala, ngokuthandwa kwezimoto zikagesi, isidingo semakethe samabhethri e-lithium angu-18650 sizoqhubeka nokukhula.Ibhethri ye-lithium engu-18650 inomthamo omkhulu wamandla, impilo ende kanye nokushaja okuhle nokusebenza kokukhipha, okuyisinqumo esihle samabhethri emoto kagesi.Ngokukhula okusheshayo kwemakethe yezimoto zikagesi, isidingo semakethe samabhethri e-lithium ayi-18650 sizoqhubeka nokukhula.
Okwesibili, ngokuthuthuka okusheshayo kwamandla avuselelekayo, amabhethri e-lithium angu-18650 nawo azosetshenziswa kabanzi.Kumandla elanga namandla omoya, amabhethri e-lithium angu-18650 asetshenziswa kabanzi emishinini yokugcina amandla.Ngokukhula okuqhubekayo kwemakethe yamandla avuselelekayo, isidingo semakethe samabhethri e-lithium angu-18650 sizoqhubeka nokukhula.
Ngaphezu kwalokho, ngokuqhubeka okuqhubekayo kobuchwepheshe, ukusebenza nokuphepha kwamabhethri e-lithium angu-18650 kuzothuthukiswa nakakhulu.Njengamanje, abakhiqizi abakhulu bebhethri bahlala bethuthukisa ubuchwepheshe bokukhiqiza, bethuthukisa ukuphepha nokuthembeka kwamabhethri ukuze bahlangabezane nesidingo esikhulayo semakethe.
Kafushane, ibhethri ye-lithium engu-18650 inamathuba abanzi kakhulu okuthuthuka.Eminyakeni embalwa ezayo, ngokukhula okuqhubekayo kwezimoto zikagesi kanye nezimakethe zamandla avuselelekayo, isidingo semakethe samabhethri e-lithium angu-18650 sizoqhubeka sikhula.Ngesikhathi esifanayo, ngokuthuthuka okuqhubekayo kobuchwepheshe, ukusebenza nokuphepha kwamabhethri e-lithium angu-18650 kuzothuthukiswa nakakhulu.Ngakho-ke, ukutshala imali ezinkampanini zokukhiqiza ibhethri ye-lithium ye-18650 kuzoba namandla amakhulu okuthuthuka.
1. Isinyathelo sendlela yokulinganisa ye-18650 lithium umthamo webhethri yesilinganiso
1. Indlela elula njalo ukumelana nogesi.Udinga ukusebenzisa i-multimeter kanye nokumelana namandla aphezulu.Okokuqala nje, ungashaja, njengasemshinini, kumakhalekhukhwini wakho.Ukuxhuma umthwalo ogcwele webhethri kulokhu kumelana, imvamisa ukumelana nosimende okungu-10 ohm 5W kuyakhishwa futhi kukhishelwe ku-voltage engaphansi kuka-2.75V, umthamo wesikhathi sokuphuma esiphelele = 0.37a * isikhathi silula, kodwa kunomehluko othile wephutha I-Essence
2. Indlela ehlelekile: Sebenzisa umtshina webhethri, uqale uyishaje ifike ku-4.20V, bese uyibamba ihora lokugeleza kukagesi njalo.Indlela yokulamula izikhathi ezingu-0.2, njengomthamo we-1000mAh.Isikhathi*samanje njalo = umthamo webhethri Lokhu kwenziwa ngokuhambisana nemithetho yebhethri ye-lithium ejwayelekile kazwelonke engu-18287.Uma ibhethri ye-nickel -metal hydride, kuyafana, kodwa indlela yokushaja ayiyona i-voltage engaguquki, kodwa ukukhishwa kufanele kunikezelwe indlela ngayinye nge-1.0V.
