Kev Taw Qhia:
Cov roj teeb lithiumtau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub, muab hluav taws xob rau txhua yam los ntawm cov xov tooj ntse thiab cov laptops mus rau cov tsheb fais fab thiab cov tshuab khaws cia hluav taws xob. Cov roj teeb lithium tau siv dav dav, tab sis muaj cov xwm txheej ntawm hluav taws thiab tawg, uas, txawm tias tsis tshua muaj, tau ua rau muaj kev txhawj xeeb txog lawv txoj kev nyab xeeb. Kev nkag siab txog cov yam ntxwv uas yuav ua rau muaj cov xwm txheej zoo li no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm kev siv cov roj teeb lithium.
Kev tawg ntawm cov roj teeb lithium yog qhov teeb meem kev nyab xeeb loj heev, thiab cov ua rau lawv tshwm sim yog qhov nyuaj thiab ntau yam, feem ntau suav nrog cov yam ntxwv sab hauv thiab sab nraud.
Cov yam ntxwv sab hauv
Sab hauv luv luv Circuit Court
Tsis txaus lub peev xwm ntawm cov electrode tsis zoo: Thaum lub peev xwm ntawm cov electrode tsis zoo ntawm cov electrode zoo ntawm lub roj teeb lithium tsis txaus, cov lithium atoms tsim thaum lub sijhawm them tsis tuaj yeem ntxig rau hauv cov qauv interlayer ntawm cov electrode graphite tsis zoo, thiab yuav precipitate rau ntawm qhov chaw ntawm cov electrode tsis zoo los ua cov siv lead ua. Kev sib sau ua ke ntev ntawm cov siv lead ua no yuav ua rau muaj luv luv Circuit Court, lub roj teeb cell tso tawm sai sai, tsim ntau cua sov, hlawv lub diaphragm, thiab tom qab ntawd ua rau muaj kev tawg.
Kev nqus dej ntawm electrode thiab electrolyte reaction: Tom qab lub electrode nqus dej, nws yuav react nrog electrolyte los tsim cov pa bulging, uas yuav ua rau luv luv sab hauv.
Teeb meem ntawm cov electrolyte: Qhov zoo thiab kev ua haujlwm ntawm cov electrolyte nws tus kheej, nrog rau qhov ntau ntawm cov kua uas txhaj thaum lub sijhawm txhaj tshuaj uas tsis ua raws li cov txheej txheem xav tau, yuav cuam tshuam rau kev nyab xeeb ntawm lub roj teeb.
Cov Khoom Tsis Huv Hauv Cov Txheej Txheem Tsim Khoom: Cov Khoom Tsis Huv, plua plav, thiab lwm yam uas yuav muaj thaum lub sijhawm tsim roj teeb kuj tseem yuav ua rau muaj cov voj voog luv luv.
Thermal khiav tawm
Thaum lub roj teeb lithium kub dhau, yuav muaj kev hloov pauv tshuaj lom neeg exothermic ntawm cov khoom sab hauv ntawm lub roj teeb, thiab cov pa roj uas yooj yim hlawv xws li hydrogen, carbon monoxide, thiab methane yuav tsim tawm. Cov kev hloov pauv no yuav ua rau muaj kev hloov pauv tshiab, tsim ib lub voj voog phem, ua rau qhov kub thiab siab hauv lub roj teeb nce siab heev, thiab thaum kawg ua rau muaj kev tawg.
Kev them roj teeb ntau dhau mus ntev
Nyob rau hauv cov xwm txheej them ntev, kev them ntau dhau thiab overcurrent kuj tseem yuav ua rau kub thiab siab, uas ua rau muaj kev phom sij rau kev nyab xeeb.
Cov yam ntxwv sab nraud
Sab nraud luv luv Circuit Court
Txawm hais tias cov voj voog luv luv sab nraud tsis tshua ua rau lub roj teeb kub dhau, cov voj voog luv luv sab nraud mus sij hawm ntev yuav ua rau cov chaw sib txuas tsis muaj zog hauv lub voj voog hlawv, uas ua rau muaj teeb meem kev nyab xeeb loj dua.
Kub sab nraud siab
Nyob rau hauv qhov chaw kub siab, cov electrolyte solvent ntawm lithium roj teeb evaporates sai dua, cov ntaub ntawv electrode nthuav dav, thiab sab hauv tsis kam nce, uas yuav ua rau xau, luv luv circuits, thiab lwm yam, ua rau tawg lossis hluav taws.
Kev co lossis kev puas tsuaj ntawm lub cev
Thaum cov roj teeb lithium raug kev co lossis kev puas tsuaj loj heev thaum lub sijhawm thauj mus los, siv lossis txij nkawm, lub diaphragm lossis electrolyte ntawm lub roj teeb yuav raug puas tsuaj, ua rau muaj kev sib cuag ncaj qha ntawm cov hlau lithium thiab electrolyte, ua rau muaj kev cuam tshuam exothermic, thiab thaum kawg ua rau tawg lossis hluav taws.
Teeb meem them nqi
Kev them ntau dhau: Lub voj voog tiv thaiv tsis tuaj yeem tswj tau lossis lub txee ntes tsis tuaj yeem tswj tau, ua rau lub zog them hluav taws xob ntau dua li qhov ntsuas hluav taws xob ntawm lub roj teeb, ua rau cov electrolyte decomposition, cov tshuaj tiv thaiv hnyav hauv lub roj teeb, thiab nce siab sai hauv lub zog sab hauv ntawm lub roj teeb, uas tuaj yeem ua rau tawg.
Overcurrent: Kev them tam sim no ntau dhau yuav ua rau lithium ions tsis muaj sijhawm los nkag mus rau hauv daim ncej, thiab lithium hlau raug tsim rau ntawm qhov chaw ntawm daim ncej, nkag mus rau hauv lub diaphragm, ua rau muaj kev luv luv ntawm cov ncej zoo thiab tsis zoo thiab tawg.
Xaus lus
Cov ua rau lub roj teeb lithium tawg yog vim muaj luv luv hauv lub voj voog, thermal runaway, lub roj teeb cell them ntau dhau mus ntev, luv luv sab nraud, kub siab sab nraud, kev co lossis kev puas tsuaj, teeb meem them, thiab lwm yam. Yog li ntawd, thaum siv thiab tswj cov roj teeb lithium, nws yog ib qho tsim nyog yuav tsum ua raws li cov cai kev nyab xeeb kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm lub roj teeb. Tib lub sijhawm, kev txhawb nqa kev saib xyuas kev nyab xeeb thiab kev tiv thaiv kuj yog cov txheej txheem tseem ceeb los tiv thaiv cov roj teeb lithium tawg.
