Qhuav Electrode Txheej Txheem: Lub Ntsiab Rau Kev Loj Hlob Ntawm Lub Siab -Kev Ua Haujlwm Zoo- Lub Xeev Roj Teeb

Nyob rau hauv tag nrho cov -khoom- lub xeev roj teeb, cov kua electrolyte yog hloov los ntawm ib tug khoom- xeev electrolyte membrane. Yog li ntawd, lub hauv ntej- txheej txheem tsim khoom kawg yuav tsum tau npaj cov khoom siv electrolyte zaj duab xis ntxiv rau cov ntawv zoo thiab tsis zoo electrode. Cov txheej txheem no yog qhov txuas tseem ceeb hauv kev tsim cov roj teeb ua haujlwm, ncaj qha txiav txim siab qhov ua tau zoo thiab qhov zoo ntawm lub xov tooj ntawm tes kawg. Thaum cov txheej txheem ntub dej tam sim no yeej muaj zog- lub xeev cov roj teeb ntau lawm, cov txheej txheem qhuav tau nce zuj zus los ua cov kev taw qhia tseem ceeb rau yav tom ntej - tiam khoom - xeev roj teeb pem hauv ntej- thev naus laus zis, ua tsaug rau nws cov txiaj ntsig zoo hauv cov nqi, kev ua haujlwm zoo, thiab cov khoom siv sib xws.

01. Kev hloov pauv tseem ceeb hauv cov khoom khov-Lub Xeev Roj Teeb Ua Ntej-Kev Tsim Ntau Lawm

Cov txheej txheem tsim khoom rau cov khoom siv - lub xeev cov roj teeb sib txawv ntawm cov roj teeb ua kua ib txwm muaj. Sab pem hauv ntej -kawg npaj zaj duab xis ntu yog qhov tseem ceeb, kev hloov pauv hauv cov txheej txheem tsim roj teeb. Cov theem no ncaj qha dictates lub tiav cell lub zog ceev, tus nqi kev ua tau zoo, thiab lub voj voog lub neej. Hauv tag nrho cov-khoom- lub xeev cov roj teeb, cov khoom-state electrolyte membrane hloov cov kua electrolyte. Yog li ntawd, pem hauv ntej- qhov kawg kev npaj yuav tsum tsis tsuas yog cov pa zoo thiab tsis zoo electrode nplooj ntawv xwb tab sis kuj yog cov khoom{10}}state electrolyte zaj duab xis. Qhov kev hloov pauv tseem ceeb no qhia txog cov kev cov nyom tshiab thiab ib txhij nthuav qhia cov hauv kev rau kev txhim kho cov txheej txheem.

02. Kev Hloov Kho Tshuab: Lub Leap los ntawm Kev ntub dej kom qhuav

Cov khoom tam sim no - lub xeev roj teeb pem hauv ntej - cov txheej txheem npaj kawg yog feem ntau faib ua ob txoj kev: ntub thiab qhuav. Cov txheej txheem ntub dej tseem tso siab rau cov kuab tshuaj ntawm cov roj teeb ua kua ib txwm siv, qhov twg cov khoom siv hluav taws xob lossis cov khoom siv electrolyte sib xyaw nrog cov ntaub ntawv los ua cov slurry, coated, thiab tom qab ntawd qhuav kom tiav cov yeeb yaj kiab.

Thaum cov txheej txheem no tseem paub tab, nws muaj qhov tsis zoo: nws yuav tsum tau siv ntau cov tshuaj lom neeg cov kuab tshuaj lom (xws li NMP), yuav tsum muaj siab -zog- cov kauj ruam noj kom qhuav thiab hnyav rov qab, thiab txwv tsis pub siv qee yam kev txiav - cov ntaub ntawv rhiab rau cov kuab tshuaj.

Nyob rau hauv sib piv, cov txheej txheem qhuav innovates electrode manufacturing los ntawm kev tshem tawm cov kev siv cov kuab tshuaj thiab cov tom qab ziab cov kauj ruam. Cov txheej txheem qhuav cia siab ntau rau siab -shear dry mixing and fibrillation equipment to achieve uniform material dispersion and pre-forming, by multi-roll pressing to complete the film formation directly.

Cov txiaj ntsig tseem ceeb ntawm kev tsim cov yeeb yaj kiab qhuav yog pom tseeb thoob plaws peb qhov ntev:

• Tus Nqi Ua Haujlwm:Los ntawm kev tshem tawm cov txheej txheej, ziab, thiab hnyav rov qab theem, cov cuab yeej siv tau qis dua, kev siv hluav taws xob txo qis, thiab tag nrho cov nqi ntawm tes tsim tau raug txo los ntawm kwv yees li 18%.

• Txhim khu kev ua tau zoo:Cov txheej txheem qhuav ua tau zoo ua rau cov khoom siv sib xyaw ua ke, ua rau lub zog ntom ntom ntawm li 20%. SAIC Group lub semi-khoom{3}} lub xeev roj teeb, koom ua ke rau hauv nws cov qauv MG4, tau ua tiav lub zog ceev ntawm 400Wh / kg, txhawb nqa 12-feeb them ceev rau 400 km.

• Environmental thiab Material Compatibility:Cov txheej txheem qhuav tshem tawm qhov xav tau rau cov kuab tshuaj lom, daws cov teeb meem ib puag ncig ntawm cov txheej txheem ntub dej. Ib yam li ntawd, nws ua rau kev siv cov nqi ntau dua - cov khoom siv tau zoo (xws li manganese -raws li cathodes).

03. Technology Matrix: Diversified Paths rau qhuav zaj duab xis tsim

Qhuav zaj duab xis tsim tsis yog ib tug txheej txheem tab sis ib tug matrix encompassing ntau yam technical routes. Tam sim no, ntau tus neeg sawv cev qhuav electrode npaj thev naus laus zis feem ntau suav nrog rau hom:

• Fibrillation Method:Siv lub zog shear siab los ua fibrillate lub binder, ua kom nws nruj nreem kaw cov ntaub ntawv nquag thiab cov khoom siv hluav taws xob, tsim tus kheej -txhawb electrode zaj duab xis. Cov txheej txheem no xav tau siab heev shear quab yuam thiab tswj qhov kub thiab txias los ntawm cov khoom siv.

• Dry Spray Deposition:Siv cov hmoov uas tau them, uas tau muab tso rau hauv cov khoom siv tam sim no nyob rau hauv ib qho hluav taws xob, los ntawm kev kub nias kom yaj thiab kho cov ntawv khi, ua rau tus kheej - txhawb nqa zaj duab xis.

• Lwm Txoj Kev:Vapor deposition, kub-melt extrusion, ncaj qha nias, thiab 3D luam ntawv yog siv raws li cov khoom sib txawv thiab cov xwm txheej ntawm daim ntawv thov.

Cov kev sib txawv no sib txawv hauv cov qauv kev, cov ntaub ntawv siv tau, zaj duab xis- tsim muaj peev xwm, thiab cov cuab yeej siv tsis yooj yim, thiab haum rau cov kev siv sib txawv xws li loj - nplai, hloov tau electrodes, me - cov khoom siv loj, thiab cov ntawv tuab electrode.

Kev sib piv ntawm Major Dry Film Formation Technical Routes

Kev lag luam feem ntau txiav txim siab Binder Fibrillation Method los ua kom pom kev ua tau zoo dua kev ruaj ntseg thiab kev ua tau zoo, tso nws ua txoj hauv kev tawm tshiab.

04. Kev Sib Tw Kev Lag Luam: Kev sib txuas ntawm qhov sib txawv ntawm chav kuaj mus rau ntau lawm

Txawm hais tias qhov zoo meej ntawm kev tsim cov yeeb yaj kiab qhuav, kev ntsuas los ntawm qhov chaw kuaj mus rau ntau lawm ntsib ntau yam teeb meem. Lub peev xwm thiab kev ua tau zoo yog qhov kev txhawj xeeb tseem ceeb. Qhuav txheej muaj peev xwm thiab ceev tseem poob qab ib txwm ntub txheej txheem, thiab uniformity thiab adhesion kev ua tau zoo thaum lub sij hawm dav - hom tshuaj tsuag yuav tsum tau txhim kho tseem ceeb.

Txheej uniformity thiab kev tswj kom zoo muaj lwm qhov kev sib tw loj. Tsis yog- cov txheej txheem qhuav electrode tuaj yeem tsim "qhov kub" nyob rau hauv electrode, ua rau kom ceev roj teeb kev ua haujlwm tsis zoo thiab muaj peev xwm muaj kev nyab xeeb.

Binder thiab cov ntaub ntawv compatibility kuj xav tau ntxiv optimization. Ua tiav kev faib tawm ntawm PTFE fibrils hauv qhov sib tov thaum tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob yog qhov tseem ceeb. Tsis tas li ntawd, PTFE tsis ruaj khov ntawm qhov muaj peev xwm tsawg thiab ua rau tsis muaj zog nrog lithium, uas txwv nws daim ntawv thov hauv qhov tsis zoo electrodes.

Cov kev sib tw ntawm cov cuab yeej siv yog sib npaug sib npaug. Cov txheej txheem qhuav imposes xav tau ntau dua ntawm cov tub ntxhais cov menyuam - nias machinery. Kev ua tau zoo thiab kev ua haujlwm ntawm lub tshuab calendaring raws li cov khoom siv tseem ceeb yog qhov tseem ceeb rau kev txiav txim siab cov txheej txheem qhuav qhov kev muaj peev xwm rau kev tsim khoom loj.

TOB NEW ENERGYyog nquag ua hauj lwm los daws cov teeb meem no, aiming tswj cov binder cov ntsiab lus nyob rau hauv qhov tsis zoo electrode mus rau 0.7% thiab cov zoo electrode hauv qab no 1.5% kom ua tau zoo dua, tsawg - nqi zaj duab xis- ua tau zoo.

05. Cov Khoom Siv Tsim Kho Tshiab: Lub Zog Tseem Ceeb Tsav Tsav Kev Ua Haujlwm Qhuav

Cov cuab yeej siv feem ntau yog spearheads industrialization ntawm cov khoom- xeev cov roj teeb. Nyob rau hauv lub realm ntawm qhuav zaj duab xis, cov cuab yeej innovation yog tus tsav tsheb tseem ceeb rau kev siv technology.
