Cov txheej txheem conductive, tseem hu ua pre- txheej, hauv kev lag luam roj teeb lithium feem ntau yog hais txog cov txheej txheem hluav taws xob siv rau saum npoo ntawm qhov zoo electrode tam sim no collector-aluminium foil. Aluminium foil coated nrog no conductive txheej yog hu ua pre-coated aluminium foil los yog tsuas yog coated txhuas ntawv nyiaj. Cov txheej txheem txheej hauv cov roj teeb lithium zoo txhim kho electrode adhesion, txo tus nqi ntawm cov ntaub ntawv siv, thiab txhim kho cov roj teeb hluav taws xob zoo. Nws qhov kev sim ua ntej tshaj plaws hauv cov roj teeb tuaj yeem rov qab mus rau xyoo 1970s, thiab nws tau vam meej nrog txoj kev loj hlob ntawm kev lag luam hluav taws xob tshiab, tshwj xeeb tshaj yog cov roj teeb lithium hlau phosphate, dhau los ua ib qho kev nrhiav heev - tom qab siv tshuab tshiab lossis khoom siv.
Lub roj teeb tsim qauv yuav tsum muab ob txheej tiv thaiv hluav taws xob tiv thaiv overcharging, tshaj - tso tawm, thiab overcurrent. Yog hais tias lub roj teeb tawg tom qab tshem tawm lub rooj tsav xwm tiv thaiv, nws qhia tau hais tias qhov teeb meem tsim. Thaum txoj kev no muab ob txheej ntawm kev tiv thaiv, cov neeg siv khoom feem ntau yuav tsis yog - thawj chargers tom qab lawv tus kheej chargers tawg. Charger manufacturers, rau cov nqi yog vim li cas, feem ntau tshem tawm lub charger maub los kom txo nqi. Yog li ntawd, inferior chargers tsav tawm cov superior, ua rau ib tug proliferation ntawm substandard chargers nyob rau hauv lub lag luam. Qhov no tshem tawm thawj thiab tseem ceeb tshaj plaws ntawm kev tiv thaiv tiv thaiv overcharge. Overcharge yog qhov tseem ceeb tshaj plaws uas ua rau lub roj teeb tawg; Yog li ntawd, cov khoom siv hluav taws xob tsis zoo tuaj yeem suav tias yog qhov ua txhaum tom qab cov roj teeb tawg. Tau kawg, tsis yog txhua lub roj teeb ua haujlwm siv cov lus saum toj no - piav qhia txog kev daws teeb meem. Qee qhov xwm txheej, lub pob roj teeb yuav muaj lub teeb tsa ua - hauv kev them nyiaj tswj hwm.
