Taw qhia:
Lithium roj teebtau dhau los ua ib feem tseem ceeb ntawm peb lub neej niaj hnub, txhawb txhua yam ntawm smartphones thiab laptops mus rau lub tsheb fais fab thiab lub zog cia. Cov roj teeb lithium tau siv dav, tab sis tau muaj qhov tshwm sim ntawm hluav taws kub 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 xwm txheej uas yuav ua rau muaj qhov xwm txheej zoo li no yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm kev siv roj teeb lithium.
Lithium roj teeb tawg yog qhov teeb meem kev nyab xeeb loj, thiab qhov ua rau ntawm lawv qhov tshwm sim yog qhov nyuaj thiab ntau yam, feem ntau suav nrog cov khoom sab hauv thiab sab nraud.
Sab hauv yam
Internal luv Circuit Court
Tsis muaj peev xwm tsis zoo electrode: Thaum qhov tsis zoo electrode muaj peev xwm ntawm qhov zoo electrode ntawm lithium roj teeb tsis txaus, lithium atoms generated thaum lub sij hawm them nyiaj yuav tsis muab tso rau hauv lub interlayer qauv ntawm qhov tsis zoo electrode graphite, thiab yuav precipitate nyob rau saum npoo ntawm qhov tsis zoo electrode. tsim cov crystals. Lub sij hawm ntev ntawm cov pob zeb no tuaj yeem ua rau luv luv, lub roj teeb ntawm tes tawm sai sai, ua kom muaj cua sov ntau, hlawv lub diaphragm, thiab tom qab ntawd ua rau tawg.
Electrode dej nqus thiab cov tshuaj tiv thaiv electrolyte: Tom qab cov electrode absorbs dej, nws yuav hnov mob nrog cov electrolyte los tsim cov huab cua bulges, uas tej zaum yuav ua rau sab hauv luv luv circuits.
Electrolyte teeb meem: Qhov zoo thiab kev ua tau zoo ntawm cov electrolyte nws tus kheej, nrog rau cov kua dej thaum txhaj tshuaj uas tsis ua raws li cov txheej txheem, yuav cuam tshuam rau kev nyab xeeb ntawm lub roj teeb.
Cov impurities nyob rau hauv cov txheej txheem ntau lawm: impurities, plua plav, thiab lwm yam uas tej zaum yuav muaj nyob rau hauv lub roj teeb txheej txheem kuj yuav ua rau micro-short circuits.
Thermal khiav
Thaum thermal runaway tshwm sim hauv lub roj teeb lithium, cov tshuaj tiv thaiv exothermic yuav tshwm sim ntawm cov khoom siv hauv lub roj teeb, thiab cov roj hluav taws xob xws li hydrogen, carbon monoxide, thiab methane yuav raug tsim. Cov kev cuam tshuam no yuav ua rau muaj kev cuam tshuam sab nraud tshiab, ua rau lub voj voog tsis zoo, ua rau qhov kub thiab txias hauv lub roj teeb nce siab, thiab thaum kawg ua rau tawg.
Lub sij hawm ntev overcharge ntawm lub roj teeb ntawm tes
Nyob rau hauv lub sij hawm ntev them nqi, overcharging thiab overcurrent kuj yuav ua rau kub thiab kub siab, uas nyob rau hauv lem yuav ua rau muaj kev nyab xeeb.
Sab nraud yam
Sab nraud luv luv Circuit Court
Txawm hais tias cov hluav taws xob luv luv sab nraud tsis tshua ncaj qha ua rau lub roj teeb thermal khiav tawm, lub sijhawm ntev sab nraud luv luv yuav ua rau cov ntsiab lus tsis muaj zog hauv Circuit Court hlawv, uas yuav ua rau muaj teeb meem kev nyab xeeb loj dua.
Sab nraud kub
Nyob rau hauv ib puag ncig kub, cov kuab tshuaj electrolyte ntawm lithium roj teeb evaporates sai dua, cov ntaub ntawv electrode nthuav dav, thiab cov kev tiv thaiv sab hauv tuaj yeem ua rau cov dej xau, luv Circuit Court, thiab lwm yam, ua rau tawg lossis hluav taws kub.
Mechanical vibration lossis puas
Thaum cov roj teeb lithium raug rau cov neeg kho tshuab kev co lossis kev puas tsuaj thaum lub sijhawm thauj mus los, siv lossis tu, lub diaphragm lossis electrolyte ntawm lub roj teeb yuav raug puas ntsoog, ua rau muaj kev sib cuag ncaj qha ntawm cov hlau lithium thiab electrolyte, ua rau cov tshuaj tiv thaiv exothermic, thiab thaum kawg ua rau tawg lossis tawg. hluav taws.
Teeb meem them
Overcharge: Kev tiv thaiv hluav taws xob tsis muaj kev tswj hwm lossis lub txee kuaj pom tsis muaj kev tswj hwm, ua rau lub zog them hluav taws xob ntau dua li qhov ntsuas hluav taws xob ntawm lub roj teeb, ua rau electrolyte decomposition, kev tawm tsam hnyav hauv lub roj teeb, thiab nrawm nrawm rau sab hauv. siab ntawm lub roj teeb, uas tuaj yeem ua rau tawg.
Overcurrent: Kev them nyiaj ntau dhau tuaj yeem ua rau lithium ions tsis muaj sijhawm los kos rau hauv cov ncej, thiab lithium hlau yog tsim rau saum npoo ntawm tus ncej, nkag mus rau lub diaphragm, ua rau luv luv luv ntawm cov ncej zoo thiab tsis zoo thiab tawg. .
Xaus
Qhov ua rau ntawm cov roj teeb lithium tawg yog cuam tshuam nrog cov luv luv Circuit Court, thermal runaway, lub sij hawm ntev overcharging ntawm lub roj teeb ntawm tes, sab nraud luv circuits, sab nraud kub, mechanical vibration lossis puas, 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 tswj kev nyab xeeb kom ruaj ntseg thiab ruaj ntseg ntawm lub roj teeb. Nyob rau tib lub sijhawm, ntxiv dag zog rau kev saib xyuas kev nyab xeeb thiab kev tiv thaiv kev tiv thaiv kuj tseem yog txoj hauv kev los tiv thaiv lithium roj teeb tawg.
