daim ntawv hlau lithium 18650 tsha yim
Kev tsim tawm ntawm lub 18650 lithium battery yog ib qhov kev txhim kho tshiab hauv kev lag luam ntawm kev siv lub zog tuaj siv dua, muaj daim duab cylinder uas sib npaug 18mm nyob rau sab qaum thiab 65mm nyob rau sab dav. Qhov chaw tso zog no muaj kev ruaj khov siab, kev nyob zoo zoo, thiab kev ua haujlwm zoo nyob rau hauv ib qhov kis kis. Lub battery no siv lithium-ion chemistry kom pom voltage tshaj tshooj ntawm 3.7V thiab feem ntau muaj qhov capacity uas tau los ntawm 2000mAh mus rau 3500mAh. Kev tsim hauv nws muaj ntau yam kev tswj zog xws li ib qhov vent uas tshuaj txaus siab, ib qhov kev tswj temperature, thiab kev tswj kom tsis pub short-circuit. Hawm ntawm lub cell muaj cov ntaub ntawv cathode thiab anode uas tau tsim los ntawm kev kho tshuaj, separated by a specialized membrane that facilitates ion transfer while preventing electrical shorts. Cov batteries no ua haujlwm zoo hauv ntau yam kev siv xws li electronics loj me zoo li laptops thiab power banks, thiab kuj tseem siv hauv kev lag luam thiab yas tshwj tsis. Qhov sib npaug ntawm lub 18650 tau tsim rau ib qhov standard hauv kev lag luam, tiam sis muaj kev sib thauj sib nrog zoo thiab kev sib ntxig nrog rau ntau yam khoom sib txawv. Qhov kev ua haujlwm zoo ntawm nws nyob rau hauv qhov discharge cycle, ntxiv rau qhov self-discharge rate tsuas yog me me thiab extended cycle life, ua rau nws muaj qhov tseem ceeb heev rau cov kev siv tshwj tsis uas xav tau lub zog tshaj tshooj.
