Cov hluav taws xob graphite ua lub luag haujlwm tseem ceeb hauv kev tsim cov tsheb fais fab tshiab. Cov hluav taws xob graphite yog ib feem tseem ceeb ntawm cov roj teeb lithium-ion, thiab cov roj teeb lithium-ion yog ib qho ntawm cov roj teeb fais fab siv ntau tshaj plaws hauv cov tsheb fais fab tshiab. Yog li ntawd, kev ua tau zoo thiab zoo ntawm cov hluav taws xob graphite cuam tshuam ncaj qha rau qhov kev tsav tsheb, qhov ceev ntawm kev them thiab kev nyab xeeb ntawm cov tsheb fais fab tshiab thiab lwm yam cim tseem ceeb.
Ua ntej tshaj plaws, lub luag haujlwm ntawm graphite electrodes hauv cov tsheb fais fab tshiab yog qhov pom tseeb hauv cov roj teeb lithium-ion. Lithium-ion roj teeb yog lub roj teeb fais fab tseem ceeb hauv cov tsheb fais fab tam sim no, los ntawm cov electrode zoo, electrode tsis zoo thiab electrolyte peb yam khoom kom ua tiav kev khaws cia thiab tso tawm lub zog hluav taws xob. Ntawm lawv, cov electrode tsis zoo feem ntau siv cov khoom siv graphite ua cov khoom tseem ceeb, thiab graphite electrode yog qhov chaw tseem ceeb ntawm cov lithium ions hauv cov txheej txheem khaws cia thiab tso tawm. Kev ua tau zoo ntawm graphite electrode cuam tshuam ncaj qha rau qhov ceev them, lub neej voj voog thiab kev nyab xeeb ntawm cov roj teeb lithium-ion.
Qhov thib ob, nrog rau kev loj hlob sai ntawm cov tsheb fais fab tshiab thiab kev nce ntxiv ntawm kev thov ua lag luam, qhov xav tau rau cov hluav taws xob graphite kuj nce ntxiv. Cov hluav taws xob graphite ib txwm muaj teeb meem thermal runaway thiab kev nyab xeeb nyob rau hauv lub zog siab, kev them ceev ceev thiab qhov kub siab, uas cuam tshuam loj heev rau kev ua haujlwm thiab kev ruaj khov ntawm lub roj teeb. Yog li ntawd, kev tsim cov khoom siv hluav taws xob graphite tshiab nrog kev ua tau zoo thiab kev nyab xeeb siab tau dhau los ua ib qho ntawm cov ncauj lus kub hauv thaj chaw ntawm cov tsheb fais fab tshiab.
Qhov thib peb, qib kev tshawb fawb thiab kev txhim kho thiab kev tsim khoom siv hluav taws xob ntawm cov hluav taws xob graphite cuam tshuam ncaj qha rau kev sib tw ua lag luam ntawm cov tsheb fais fab tshiab. Nrog rau kev nce qib tas mus li ntawm cov thev naus laus zis roj teeb thiab kev txhim kho cov kev cai ua haujlwm roj teeb los ntawm cov tuam txhab tsim tsheb, kev ua tau zoo thiab tus nqi ntawm cov hluav taws xob graphite tau dhau los ua cov yam tseem ceeb uas cuam tshuam rau tag nrho cov saw hlau kev lag luam tsheb fais fab tshiab. Tsuas yog los ntawm kev txhim kho qib kev siv hluav taws xob ntawm cov hluav taws xob graphite thiab txo cov nqi tsim khoom peb thiaj li ua tiav kev txhim kho ruaj khov ntawm cov tsheb fais fab tshiab hauv kev ua tau zoo, tus nqi thiab feem ntawm kev ua lag luam.
Hauv kev xaus lus, cov electrodes graphite tsis tuaj yeem sib cais los ntawm kev tsim cov tsheb fais fab tshiab. Raws li ib feem tseem ceeb ntawm cov roj teeb lithium-ion, cov electrodes graphite cuam tshuam ncaj qha rau kev ua tau zoo, kev nyab xeeb thiab kev sib tw ua lag luam ntawm cov tsheb fais fab tshiab. Yav tom ntej, nrog rau kev txhim kho tas mus li ntawm kev lag luam tsheb fais fab tshiab thiab kev tsim kho tshiab, kev tshawb fawb thiab kev txhim kho thiab kev tsim khoom ntawm cov electrodes graphite yuav txuas ntxiv mus tau txais kev saib xyuas, thiab yuav ua lub luag haujlwm tseem ceeb dua hauv kev lag luam ntawm cov tsheb fais fab tshiab.
