Nyob rau hauv ib lub sij hawm cim los ntawm kev xav tau ntau ntxiv rau cov khoom siv hluav taws xob tauj dua tshiab, cov roj teeb lithium-ion tau tshwm sim los ua ib qho tseem ceeb hauv kev siv hluav taws xob cia.Cov roj teeb no muaj lub zog siab ceev, lub neej ntev dua, thiab lub sijhawm rov ua dua sai dua, ua rau lawv zoo tagnrho rau kev siv lub zog hluav taws xob, cov khoom siv hluav taws xob portable, thiab txawm tias lub zog loj loj.Txawm li cas los xij, qhov kev loj hlob sai ntawm kev sivlithium-ion roj teebkuj ua rau muaj kev txhawj xeeb txog kev nyab xeeb, tshwj xeeb yog hais txog kev tiv thaiv hluav taws.
Lithium-ion roj teebtau paub tias yuav ua rau muaj hluav taws kub, txawm tias qhov tsawg tsawg.Txawm li cas los xij, ob peb qhov xwm txheej loj uas muaj cov roj teeb hluav taws xob tau tsa lub tswb nrov.Txhawm rau kom muaj kev nyab xeeb thiab dav siv cov roj teeb lithium-ion, kev nce qib hauv kev tiv thaiv hluav taws yog qhov tseem ceeb.
Ib qho ntawm cov laj thawj tseem ceeb ntawm lithium-ion roj teeb hluav taws xob yog qhov tshwm sim thermal runaway.Qhov no tshwm sim thaum lub roj teeb sab hauv kub nce mus rau qhov tseem ceeb, ua rau tso cov roj hluav taws xob hluav taws xob thiab muaj feem cuam tshuam rau lub roj teeb.Txhawm rau tiv thaiv thermal runaway, cov kws tshawb fawb tau siv ntau txoj hauv kev los txhim kho kev tiv thaiv hluav taws.
Ib qho kev daws teeb meem yog nyob rau hauv kev tsim cov khoom siv hluav taws xob tshiab uas tsis tshua muaj siab rau thermal khiav tawm.Los ntawm kev hloov lossis hloov cov ntaub ntawv siv hauv lub roj teeb cathode, anode, thiab electrolyte, cov kws tshaj lij tsom kom ua kom cov thermal stability ntawm lithium-ion roj teeb.Piv txwv li, cov kws tshawb fawb tau sim nrog kev ntxiv cov nplaim hluav taws xob ntxiv rau lub roj teeb electrolyte, txo qhov kev pheej hmoo ntawm kev tua hluav taws.
Lwm txoj kev vam meej yog kev siv cov roj teeb tswj siab tshaj plaws (BMS) uas txuas ntxiv saib xyuas thiab tswj cov roj teeb kev ua haujlwm.Cov tshuab no tuaj yeem kuaj xyuas qhov kub thiab txias, qhov tsis sib xws ntawm qhov hluav taws xob, thiab lwm yam kev ceeb toom ntawm qhov muaj peev xwm thermal khiav.Los ntawm kev ua raws li kev ceeb toom ntxov, BMS tuaj yeem txo qhov kev pheej hmoo ntawm hluav taws los ntawm kev ua kom muaj kev nyab xeeb xws li txo tus nqi them lossis kaw lub roj teeb tag.
Tsis tas li ntawd, muaj kev loj hlob tseem ceeb ntawm kev tsim cov hluav taws tua hluav taws zoo tsim tshwj xeeb rau cov roj teeb lithium-ion.Cov txheej txheem kev tua hluav taws, xws li dej lossis ua npuas dej, yuav tsis tsim nyog rau kev tua hluav taws lithium-ion roj teeb, vim tias lawv tuaj yeem ua rau cov teeb meem hnyav dua los ntawm kev ua rau lub roj teeb tso tawm cov khoom phom sij.Raws li qhov tshwm sim, cov kws tshawb fawb tau ua haujlwm ntawm lub tshuab hluav taws xob tshiab uas siv cov tshuaj tua hluav taws tshwj xeeb, xws li cov pa roj tsis zoo lossis cov hmoov qhuav, uas tuaj yeem ua kom cov hluav taws kub zoo yam tsis muaj kev puas tsuaj rau lub roj teeb lossis tso tawm cov khoom muaj kuab lom.
Ntxiv nrog rau kev txhim kho thev naus laus zis, cov qauv kev nyab xeeb thiab cov kev cai muaj zog ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev tiv thaiv hluav taws rau cov roj teeb lithium-ion.Tsoom fwv thiab cov koom haum kev lag luam thoob ntiaj teb tab tom ua haujlwm los tsim cov txheej txheem kev nyab xeeb nruj uas npog cov roj teeb tsim, tsim khoom, kev thauj mus los, thiab pov tseg.Cov qauv no suav nrog cov kev xav tau rau kev ruaj ntseg thermal, kev ntsuas kev tsim txom, thiab cov ntaub ntawv kev nyab xeeb.Los ntawm kev ua raws li cov cai no, cov tuam ntxhab tuaj yeem lav qhov kev nyab xeeb thiab kev ntseeg siab ntawm lawv cov khoom siv roj teeb.
Tsis tas li ntawd, kev paub txog pej xeem thiab kev kawm txog kev tuav thiab khaws cia ntawm lithium-ion roj teeb yog qhov tseem ceeb.Cov neeg siv khoom yuav tsum nkag siab txog cov kev pheej hmoo cuam tshuam nrog kev siv tsis raug lossis siv tsis raug, xws li rub lub roj teeb, ua rau nws kub dhau, lossis siv lub chargers uas tsis tau tso cai.Tej yam yooj yim xws li kev zam kom tsis txhob muaj cua sov, tsis txhob tso lub roj teeb rau hauv tshav ntuj ncaj qha, thiab siv cov kab hluav taws xob uas tau pom zoo tuaj yeem mus ntev hauv kev tiv thaiv hluav taws kub.
Lub zog cia kiv puag ncig fueled los ntawmlithium-ion roj teebtuav lub peev xwm loj heev rau kev hloov pauv ntau yam kev lag luam thiab ua kom yooj yim rau kev hloov mus rau qhov chaw muaj zog ntsuab.Txawm li cas los xij, txhawm rau ua kom muaj peev xwm ua tau zoo, kev tiv thaiv hluav taws yuav tsum yog qhov tseem ceeb tshaj plaws.Los ntawm kev tshawb fawb txuas ntxiv thiab kev tsim kho tshiab, ua ke nrog cov qauv kev nyab xeeb nruj thiab lub luag haujlwm ntawm cov neeg siv khoom tus cwj pwm, peb tuaj yeem ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov roj teeb lithium-ion rau hauv peb lub neej txhua hnub.
