Lub peev xwm yog qhov tseem ceeb ntawm lub roj teeb, thiab lub peev xwm tsawg yog qhov teeb meem nquag ntsib hauv ob qho tib si kuaj thiab ntau lawm. Kab lus no tsis tuaj yeem lav tias koj yuav txheeb xyuas qhov laj thawj tam sim ntawd thaum ntsib qhov teeb meem tsawg -, tab sis nws yuav muab txoj hauv kev yooj yim.
Thaum hnov tias lub xovtooj ntawm tes muaj peev xwm tsawg, thawj cov lus teb yuav tsum yog kom paub meej tias qhov tsawg - qhov teeb meem muaj peev xwm yog qhov tseeb. Cias muab tso, koj yuav tsum xub xyuas seb cov txheej txheem sizing yog tsis raug (piv txwv li, seb qhov paug tawm tam sim no tau teeb tsa siab dhau lossis lub sijhawm them luv luv). Yog tias cov txheej txheem sizing raug teeb tsa kom raug, cov kauj ruam tom ntej yog hloov cov ntsiab lus xeem thiab rov- ntsuas lub peev xwm ntawm tes. Tau kawg, rau ob qho tib si ntau lawm thiab cov qauv, qhov tshwm sim ntawm batch tsis muaj peev xwm tshwm sim los ntawm kev ua yuam kev hauv lub txee sizing yog tsawg heev; Feem ntau, nws txhais tau hais tias lub xov tooj ntawm tes nws tus kheej muaj teeb meem tiag tiag. Yog tias qhov kev ntsuas rov- tseem qhia tias muaj peev xwm tsawg, qhov teeb meem muaj peev xwm tsawg tuaj yeem lees paub tias muaj tseeb.
ACEY roj teeb muaj peev xwm kuaj tshuabyog siv rau kev sim roj teeb muaj peev xwm, kev tiv thaiv sab hauv, kev them nqi thiab kev ntsuas tawm, thiab lwm yam.
Thaum tsis muaj peev xwm lees paub, nws yuav tsum tau txiav txim siab ntxiv qhov zaus thiab qhov hnyav ntawm qhov teeb meem kom nkag siab txog qhov xwm txheej tiag tiag. Cov qauv feem ntau yog los ntawm ib pawg; Txawm li cas los xij, rau huab hwm coj- cov qauv tsim, muaj ob qhov xwm txheej: 'tus qauv no tsis tu ncua muaj peev xwm tsawg' thiab 'tus qauv no qee zaus muaj peev xwm tsawg.' Rau yav dhau los, kev tshuaj xyuas yuav tsum pib los ntawm qhov kev xav ntawm kev tsim, xaiv cov khoom siv, thiab cov teeb meem tawv ncauj uas tau ntsib ntev - lub sij hawm hauv kev tsim khoom raws li qhov kev txiav txim siab tseem ceeb (piv txwv li, cov khoom siv sib xyaw ua ke no puas tsis tau kuaj? Cov kab ntau lawm tsis ntev los no puas muaj qhov tsis txaus ntseeg uas ua rau muaj peev xwm tsawg tab sis tau raug tsis saib xyuas?).
Rau yav tom ntej, cov kab ntau lawm thiab cov txheej txheem kev hloov pauv yuav tsum yog lub hom phiaj tseem ceeb (piv txwv li, yog lub anode pressed nyuaj heev nyob rau hauv lub batch no? Puas yog cov kab ntau lawm shorten lub sij hawm rau kev laus dua? Tom qab qhov zaus tau lees paub, qhov tseem ceeb tsawg dua, qhov hnyav, kuj yuav tsum tau soj ntsuam - uas yog, qhov feem pua ntawm cov cell muaj peev xwm qis thiab qhov feem pua ntawm cov peev txheej hauv qab tus nqi xav tau. Kev ntsuas qhov hnyav yog ntau dua rau kev muab lub hauv paus rau kev txo qis peev txheej tshwj xeeb lossis txiav txim siab qhov tsis txaus; Nws qhov tseem ceeb hauv kev txheeb xyuas qhov teeb meem nws tus kheej tsis yog qhov tseem ceeb raws li kev lees paub ntau zaus, tab sis nws tseem yog qhov tseem ceeb.
Tom qab nkag siab qhov xwm txheej tiag tiag ntawm qhov muaj peev xwm tsawg, koj tuaj yeem qhib thawj zaug uas tau them tag nrho qis - lub peev xwm ntawm lub hlwb los tshuaj xyuas qhov cuam tshuam. Yog tias tsis muaj teeb meem, nws yuav tshwm sim los ntawm lub teeb ci cathode txheej lossis tsis txaus tsim qauv; yog tias muaj teeb meem pom ntawm lub interface, nws yuav qhia tau tias muaj teeb meem hauv cov txheej txheem tsim khoom lossis tsim.
Kev tsom xam tshwj xeeb yog raws li hauv qab no:
Ua ntej tshaj plaws,yam tsawg kawg nkaus ntawm 8pcs hlwb nrog lub peev xwm tsawg ntawm 8pcs hlwb yuav tsum tau. Tsawg- cov hlwb muaj peev xwm raug muab faib ua ob pawg rau hauv qis- muaj peev xwm A pab pawg thiab qis- muaj peev xwm B, thiab cov hlwb muaj peev xwm raug muab faib ua ob pawg rau hauv pawg A thiab pawg B tsim nyog. Tom qab ntawd tso ob lub hlwb A mus rau qhov hluav taws xob zoo li qub ntawm 3.0V, thiab tom qab ntawd tshem tawm qhov qis -capacitance thiab cov hlwb tsim nyog, nqus cov ntawv ci cathode ntawm qhov kub siab tshaj 85℃rau 24h, thiab tom qab ntawd ntsuas qhov sib txawv ntawm qhov qis -capacitance cathode daim ntawv thiab cov ntawv tsim nyog cathode. Yog tias qhov hnyav ntawm qhov tsawg-capacitance electrode thooj yog qhov qis dua li daim ntawv cathode tsim nyog lossis qis dua li cov txheej txheem ntau, nws tuaj yeem txiav txim siab tias qhov qis capacitance yog tshwm sim los ntawm lub teeb cathode txheej.
Muaj ob lub ntsiab lus uas yuav tsum tau ntxiv rau qhov hnyav ntawm cov khoom siv hluav taws xob tom qab ci: ua ntej, txawm hais tias thawj qhov tsis tuaj yeem rov qab lithium ntawm cathode yuav ua rau cathode poob qis me ntsis, qhov hnyav ntawm tag nrho cov khoom siv lithium tsis tuaj yeem tsuas yog kwv yees li 5% ntawm cathode lithium qhov chaw thiab tsawg dua 0.5% ntawm qhov hnyav ntawm cathode. Cov electrolyte tsis tuaj yeem qhuav tag thaum lub sijhawm ci, tab sis qhov hnyav ntawm qhov seem seem yog txwv rau qhov hnyav ntawm cov khoom electrode. Feem ntau, qhov yuam kev ntawm qhov hnyav ntawm tus ncej tom qab ci qhov zoo electrode tsis ntau tshaj 2% piv nrog qhov tseeb qhov hnyav ntawm winding pem hauv ntej electrode daim.
Ntxiv mus, qhov hnyav ntawm qhov zoo electrode nrog lub peev xwm tsim nyog yog muab piv nrog qhov hnyav ntawm qhov tsawg -capacitance electrode piece, uas yog qhov tseem ceeb. Qhov thib ob, tib txoj kev tsis haum rau qhov tsis zoo electrode, vim tias qhov hnyav yuav nce ntau thaum lub cev tsis zoo electrode tau tsim, tab sis qhov tsis zoo electrode qhov hnyav nce piv tom qab tsim tuaj yeem muab los ntawm kev sim los ntsuas qhov hnyav ntawm qhov tsis zoo electrode piece, thiab seb qhov capacitance qis yog tshwm sim los ntawm ntau dhau thiab tsis txaus electrode tsis zoo.
Nws yog qhov muaj hmoo yog vim li cas rau qhov tsis muaj peev xwm ntawm qhov zoo electrode tau lees paub, tab sis qhov tseeb, qhov tshwm sim ntawm qhov koob hmoov no feem ntau tsuas yog 1 ntawm 10,000. Nyob rau hauv cov ntaub ntawv no, nws nyob ntawm qhov kev soj ntsuam ntawm tsawg- ntim pawg B thiab tsim nyog pab pawg B. Pawg B hlwb yuav tsum tau them tag nrho, thiab tom qab ntawd disassemble thiab sib piv qhov sib txawv ntawm qhov tsis zoo electrode interface. Tsawg paug muaj peev xwm, qis yog sib npaug rau lub peev xwm tsis tshua muaj peev xwm, thiab qhov tsis zoo electrode tag nrho cov nqi cuam tshuam yuav txawv txav. Qhov tseeb, feem ntau, ntev npaum li qhov tsis muaj peev xwm tshwm sim, txawm hais tias lub roj teeb ntawm tes tsis muaj peev xwm lossis lub peev xwm tsim nyog, nws qhov cuam tshuam yuav muaj qhov txawv txav zoo sib xws, tab sis cov℃sib txawv. Thaum kaw lub interface ntawm lub roj teeb, nws tseem yuav tsum tau sau lub peev xwm ntawm lub xov tooj sib raug zoo tib lub sijhawm, thiab thaum kawg nws yog feem ntau xaus lus tias qhov kev cuam tshuam cuam tshuam yog qhov hnyav dua zoo ib yam li lub roj teeb ntawm tes nrog lub siab muaj peev xwm tsawg.
"Kev tuav qhov xwm txheej ntawm qhov tsis muaj peev xwm tag nrho" thiab "piv qhov zoo electrode qhov hnyav thiab qhov cuam tshuam tsis zoo ntawm lub peev xwm qis thiab cov roj teeb uas tsim nyog" yog qhov tsim nyog nkag rau hauv kev tshuaj xyuas, lees tias ob qhov teeb meem no muaj lub luag haujlwm taw qhia hauv qhov kev txiav txim zaum kawg ntawm qhov ua rau qis capacitance yav tom ntej, uas tuaj yeem ua tiav ob zaug ntawm qhov tshwm sim nrog ib nrab ntawm kev siv zog, tshwj xeeb tshaj yog cov phooj ywg.
