Kev tshuaj xyuas cov txheej txheem tsim khoom ntawm Square Aluminium-Shelled Lithium-Ion roj teeb

Raws li lub zog tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub thiab cov tshuab hluav taws xob tshiab, kev ua haujlwm thiab kev ntseeg siab ntawm lithium-ion roj teeb yog nyob ntawm qhov tseeb ntawm lawv cov txheej txheem tsim khoom. Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem square, qhov sib txuam aluminium plhaub rau prismatic lithium - ion roj teeb ua lub luag haujlwm tseem ceeb hauv kev tsim lub zog, cua sov dissipation, thiab tag nrho qhov sib xws. Cov txheej txheem tsim khoom tiav suav nrog ntau theem tseem ceeb, suav nrog kev npaj electrode, kev sib dhos ntawm tes, kev txhaj tshuaj ua kua, kev laus thiab kev sib cais, thiab ntim thiab xa khoom.

 

 

 

Kev npaj electrode yog qhov pib ntawm lithium{0}}ion roj teeb tsim. Nws cov ntsiab lus yog nyob rau hauv kev ua tiav kev ruaj ntseg thiab conductivity ntawm cov qauv electrode los ntawm cov khoom tsim nyog thiab cov txheej txheem tswj. Cov ntaub ntawv zoo electrode, xws li lithium hlau phosphate thiab ternary cov ntaub ntawv, txiav txim siab lub zog ceev thiab kev nyab xeeb kev ua tau zoo, thaum tsis zoo electrodes feem ntau yog raws li graphite, ntsuas lub voj voog stability thiab kev tswj tus nqi.

 

Thaum lub sij hawm npaj slurry, active cov ntaub ntawv, conductive agents, thiab binders yog uniformly dispersed los ntawm meej stirring los tsim ib tug ruaj khov system. The coating process evenly covers the surface of the metal current collector with a slurry, and the compaction density and interfacial bonding strength are improved through drying and rolling processes. Lub uniformity ntawm theem no ncaj qha cuam tshuam rau kev ua haujlwm ntawm tes tom ntej.

 

Tom qab electrode ua, cov electrodes yog slit raws li qhov tsim qhov ntev, muab lub hauv paus rau cov qauv ntawm tes sib txuam. Txawm hais tias theem no yog ib qho kev ua ntej - kawg, nws muaj kev cuam tshuam loj heev rau kev sib dhos tom qab thiab kev hloov kho nrog roj teeb Aluminium Housing.

 

 

Lub cell sib dhos theem feem ntau ua tiav cov txheej txheem ntawm cov txheej txheem electrode, suav nrog electrode tab welding, electrode thiab cais cais, thiab vaj tsev encapsulation. Electrode tab welding feem ntau siv laser vuam thev naus laus zis kom ntseeg tau tias tsawg -kev sib txuas tsis sib xws thiab siab sib xws.

 

Hauv cov txheej txheem sib dhos electrode, winding thiab stacking yog ob txoj hauv kev tseem ceeb. Winding yog tsim rau huab hwm coj ntau lawm, hais txog qhov nro thiab kev sib dhos raug; stacking yog qhov zoo dua ntawm kev siv qhov chaw. Txawm hais tias siv txoj kev twg los xij, lub separator yuav tsum ua kom tiav kev sib cais ntawm qhov zoo thiab qhov tsis zoo ntawm electrodes los tiv thaiv kev luv luv hauv Circuit Court.

 

Tom qab cov txheej txheem sib dhos ua tiav, lub cell yog encapsulated hauv tsev. Prismatic hlwb feem ntau siv cov ntaub ntawv ntawm tes prismatic, uas muaj cov khoom siv zoo heev thiab cov cua sov dissipation, thaum tseem ua kom yooj yim rau kev sib koom ua ke. Nyob rau hauv lub zog hluav taws xob teb, Lub Tsheb Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob tau dhau los ua cov qauv qauv tseem ceeb.

 

 

 

Cov txheej txheem txhaj tshuaj electrolyte yog qhov tseem ceeb rau lub roj teeb kom tau txais kev ua haujlwm ntawm electrochemical. Kev kho kom qhuav yuav tsum nruj ua ntej txhaj tshuaj tiv thaiv kom tsis txhob ya raws - ua rau muaj kev cuam tshuam sab nraud. Raws li ion thauj nruab nrab, tus nqi thiab ntub dej ntawm cov electrolyte ncaj qha cuam tshuam rau lub roj teeb sab hauv thiab lub peev xwm.

 

Tom qab ntawd, theem tsim, piv txwv li, thawj zaug them nqi - txheej txheem tawm, pib. Thaum lub sijhawm ua haujlwm no, cov khoom siv electrolyte interphase (SEI) cov ntaub ntawv ntawm qhov tsis zoo electrode nto. Cov yeeb yaj kiab no tiv thaiv tsis tu ncua electrolyte decomposition thaum tso cai rau lithium ions hla dhau, ua rau nws ua tus qauv tseem ceeb rau kev ua kom lub roj teeb ruaj khov.

 

Nyob rau theem no, kev sib raug zoo ntawm lub xov tooj ntawm tes thiab lithium cell aluminium plhaub yog qhov tseem ceeb tshwj xeeb, vim nws qhov kev sib khi ncaj qha cuam tshuam rau electrolyte stability thiab ntev - lub sij hawm cia siab rau.

 

 

Kev laus yog txheej txheem stabilization hauv kev tsim roj teeb, qhov twg cov tshuaj tiv thaiv sab hauv raug coj mus rau qhov sib npaug hauv lub sijhawm tshwj xeeb thiab qhov kub thiab txias. Cov txheej txheem no pab txhim kho SEI zaj duab xis qauv, txhim kho electrolyte ntub dej, thiab tso tawm cov tshuaj tiv thaiv sab nraud thaum ntxov.

 

Cov roj teeb sib txawv xav tau cov tswv yim kev laus sib txawv. Piv txwv li, cov tshuab lithium hlau phosphate feem ntau ua rau nruab nrab - lossis siab - qhov kub thiab txias los txhim kho qhov sib xws thiab lub neej voj voog. Thaum lub sij hawm tus txheej txheem no, cov khoom siv xws li txhuas alloy primamatic roj teeb rooj plaub yuav tsum muaj zoo airtightness thiab seem stability kom tsis txhob deformation los yog to.

 

 

Peev xwm sorting thiab sorting muaj xws li kev ntsuam xyuas qhov tseem ceeb tsis xws li muaj peev xwm, voltage, thiab nyob rau hauv tsis kam mus cais cov roj teeb. Cov txheej txheem no ua kom muaj kev sib raug zoo nyob rau hauv tib lub batteries ntawm cov roj teeb, yog li ua tau raws li qhov yuav tsum tau ua ntawm module lossis system - qib kev siv.

 

Piv txwv li, hauv cov roj teeb hluav taws xob, cov hlwb tsis sib xws yuav ua rau muaj kev them nyiaj ntau dhau los lossis dhau - tso tawm, cuam tshuam rau lub neej ntev thiab kev nyab xeeb. Yog li ntawd, siab -cov cuab yeej ntsuas qhov tseeb thiab cov ntaub ntawv tswj xyuas cov txheej txheem yog qhov tseem ceeb hauv theem no.

 

Nyob rau hauv cov txheej txheem, qhov ntev ntawm tes yuav tsum tau ua kom haum rau lub prismatic cell aluminium plhaub los xyuas kom meej qhov ua tau zoo thiab ruaj khov ntawm kev sib dhos tom ntej.
 

 

Tom qab ua tiav tag nrho cov electrochemical thiab kev ua tau zoo, lub roj teeb nkag mus rau theem ntim. Ntim tsis tsuas yog tiv thaiv thaum lub sij hawm thauj mus los, tab sis kuj ua hauj lwm raws li ib tug ya raws barrier, anti- tus neeg sawv cev zoo li qub, thiab shock absorber. Lub ntim sab nrauv yuav tsum tau sau meej meej cov ntaub ntawv ua tiav thiab cov lus ceeb toom kev nyab xeeb kom ua tau raws li cov cai ntawm kev thauj mus los thiab kev siv.

 

Hauv kev siv cov tswv yim, cov roj teeb feem ntau xa tuaj rau hauv module lossis pob daim ntawv, piv txwv li, siv lub roj teeb pob nrog cov qauv txhuas vaj tse los txhim kho tag nrho lub zog thiab kev ua kom sov.

 

 

 

Kev tsim khoom ntawm prismatic aluminium -cased lithium- ion roj teeb yog qhov tshwm sim ntawm kev sib koom ua ke ntawm cov khoom siv, kev tswj cov txheej txheem, thiab cov qauv tsim. Los ntawm kev npaj electrode mus rau kev xa khoom kawg, txhua kauj ruam ncaj qha cuam tshuam rau lub roj teeb kev nyab xeeb, kev ua neej, thiab kev ua haujlwm. Lub siab - zoo Deep Drawn Aluminium Battery Housing muab lub cev muaj zog rau lub cev thiab yog ib qho tseem ceeb ntawm cov khoom tseem ceeb rau kev ua tau zoo siab - roj teeb ua haujlwm.

 

 

Peb tshwj xeeb hauv R&D thiab kev tsim khoom ntawm high-cov khoom siv roj teeb muaj tseeb. Peb cov khoom lag luam npog ntau- specification txhuas plhaub rau lithium- ion roj teeb hlwb, lub zog thiab lub zog cia vaj tse, thiabcustomized pob aluminium vaj tsekev daws teeb meem. Los ntawm kev sib sib zog nqus- cov txheej txheem kos duab thiab cov txheej txheem tswj xyuas kom zoo, peb muab cov khoom zoo sib xws thiab siab - lub zog txhawb nqa rau ntau yam kev siv, dav siv rau cov tsheb tshiab, hluav taws xob hluav taws xob, thiab cov khoom siv hluav taws xob siab - kawg.
