18650 lithium-ion roj teeb them ntawm qhov kub thiab txias yuav muaj qhov cuam tshuam zoo li cas?Cia peb saib hauv qab no.
Dab tsi yog qhov cuam tshuam ntawm kev them nyiaj 18650 lithium-ion roj teeb nyob rau hauv ib puag ncig kub?
Kev them cov roj teeb lithium-ion nyob rau hauv qhov chaw kub qis ua rau muaj kev pheej hmoo ntawm kev nyab xeeb.Qhov no yog vim hais tias nrog rau qhov txo qis ntawm cov av noo, lub kinetic zog ntawm graphite tsis zoo electrode kev loj hlob ib tug deterioration nyob rau hauv lub them nqi, lub electrochemical polarization ntawm qhov tsis zoo electrode yog aggravated heev, nag lossis daus ntawm lithium hlau yog nquag mus tsim lithium. dendrites, propping li diaphragm thiab yog li ua rau luv luv Circuit Court ntawm qhov zoo thiab tsis zoo electrodes.Kom deb li deb tau los tiv thaiv lithium-ion roj teeb them ntawm qhov kub thiab txias.
Xav txog qhov kub thiab txias, qhov tsis zoo electrode ntawm lub nested lithium-ion roj teeb yuav tshwm sim ion crystals, tuaj yeem ncaj qha rau ntawm lub diaphragm, nyob rau hauv ib qho xwm txheej yuav ua rau lub micro-luv Circuit Court cuam tshuam rau lub neej thiab kev ua haujlwm, qhov hnyav dua yuav tawg!
Raws li cov kws tshaj lij kev tshawb fawb: cov roj teeb lithium-ion rau lub sijhawm luv luv nyob rau hauv qhov chaw qis qis, lossis qhov kub ntawm qhov qis, yuav cuam tshuam ib ntus rau lub peev xwm ntawm lithium-ion roj teeb, tab sis yuav tsis tsim kev puas tsuaj mus tas li. .Tab sis yog tias siv rau ib lub sij hawm ntev nyob rau hauv ib cheeb tsam uas tsis kub, los yog nyob rau hauv -40 ℃ ultra-low kub ib puag ncig, lithium-ion roj teeb tej zaum yuav khov ua rau kev puas tsuaj mus tas li.
Kev siv cov roj teeb lithium-ion kub tsis tshua muaj kev txom nyem los ntawm qhov muaj peev xwm tsawg, kev lwj loj, kev ua haujlwm tsis zoo ntawm lub voj voog, kev ua haujlwm tsis zoo ntawm lithium nag lossis daus, thiab tsis sib npaug lithium de-embedding.Txawm li cas los xij, nrog rau kev siv tshiab txuas ntxiv ntawm kev siv lub ntsiab, cov kev txwv coj los ntawm kev ua haujlwm tsis zoo ntawm cov roj teeb lithium-ion tau dhau los ua ntau thiab pom tseeb.Hauv kev ua haujlwm hnyav hauv aerospace, lub luag haujlwm hnyav, tsheb hluav taws xob thiab lwm yam haujlwm, lub roj teeb yuav tsum ua haujlwm kom zoo ntawm -40 ° C.Yog li, kev txhim kho tas mus li ntawm qhov ntsuas kub qis ntawm cov roj teeb lithium-ion muaj qhov tseem ceeb ntawm kev lag luam.
Tau kawg,Yog tias koj 18650 lithium roj teeb tau nruab nrog cov ntaub ntawv kub qis, nws tseem tuaj yeem raug them ib txwm nyob rau hauv ib puag ncig uas tsis tshua muaj kub.
