Txhim Kho Cov Roj Teeb Kev Ua Tau Zoo: Lub Luag Haujlwm Tseem Ceeb ntawm Corona Cov Neeg Muab Hluav Taws Xob Hauv Electrode Txheej
Lub ntiaj teb thawb rau hluav taws xob, los ntawm cov tsheb hluav taws xob, EVS) rau Graph {{0} nkag rau cov kev xav tau ntawm cov roj teeb thev naus laus zis. Ntawm lub siab ntawm qhov kev hloov pauv no cov lithium {2} ion roj teeb, uas yog cov kev ua tau zoo ntawm cov khoom zoo thiab muaj txiaj ntsig ntawm nws cov electrode. Thaum muaj kev saib xyuas ntau yog muab rau Chemistry thiab Cell tsim, yog qhov tseem ceeb, feem ntau dhau ntawm cov kauj ruam hauv kev tsim khoom yog kev kho kom nto. Ntawm cov txheej txheem ntau yam, tus kabmob Corona, muaj kev ntseeg siab, muaj txiaj ntsig, thiab tsis tseem ceeb roj teeb Cathode thiab anode txheej txheej.
Nkag siab txog cov kev sib tw: tsis zoo adhesion thiab wettability
Cov roj teeb hluav taws xob yog cov qauv teeb meem nyuaj. Cov nplais uas muaj cov khoom siv nquag (piv txwv li, LFP rau Cathodes; gricon rau anodes), silicing yog coodes), txhuas rau anode). Cov txheej ntub yuav tsum tau qhuav hauv qhov cub.
Lub pristine pristine thaj chaw ntawm cov ntawv hlau cov khoom siv hlau yog inherstly hydrophobic thiab muaj lub zog qis. Qhov no ua rau ob txoj kev sib tw me:
1. Tsis zoo wettability:Cov aqueous lossis hnyav - Raws li cov hlais tsis muaj qhov sib luag. Hloov chaw ntawm kev sib sau ua yeeb yaj kiab tsis zoo, nws tuaj yeem tau txais, ua rau tsis sib xws txheej txheej tuab.
2. Cov tshuaj nplaum adcesion:Yog tsis muaj kev sib tw muaj zog, cov khoom siv hluav taws xob qhuav tuaj yeem delaminate lossis tawg thaum ua cov theem tom ntej zoo li calenderent (nias) lossis txawm tias thaum lub sij hawm cycling.
Cov kev tsis zoo no ua rau txo lub zog ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom, thiab thaum kawg, roj teeb ua tsis tiav. Nov yog qhov kev kho corona kev kho mob muab cov tshuaj decisive.
Yuav ua li cas Corona kev kho mob ua haujlwm: molecular makeover
A Corona kev ua haujlwm ua haujlwm ntawm qhov yooj yim tab sis muaj zog tsis muaj zog: nws siv hluav taws xob paug mus tas li kom nce mus tas li.
Hauv ib qho system rau kev kho roj teeb hluav taws xob:
Cov neeg hlau luam hlau ntawv sib txuas hla cov menyuam hauv av.
A high-frequency, high-voltage electrode is positioned precisely above the web, creating a small air gap.
Raws li hluav taws xob hla qhov sib txawv no, nws ionizes huab cua molecules, tsim ib qho kev tswj ntshav huab cua {}} porona "paug.
Qhov laj thawj corona no tso tawm cov ntawv ci saum npoo nrog cov tshuaj ions thiab hluav taws xob, uas:
HuvCov saum npoo los ntawm kev tshem tawm cov organic paug thiab cov roj me me.
Tus lwm yamCov nplaim ntawm micro -} theem, nce nws txoj kev ntxhib thiab qhov ua tau zoo.
Kev ua hauj lwmQhov saum npoo los ntawm rhuav cov kab ke molecular thiab qhia cov pab pawg sib dhos hauv hydroxyl (xws li hydroxyl c}}} o, thiab carboxyl {}} cooh).
Cov txheej txheem no hloov cov inert, qis {- Zog} Lub zog hlau rau hauv ib qho reagent, siab} lub zog nto uas prived primed rau txheej.
Cov txiaj ntsig tseem ceeb rau cov roj teeb hluav taws xob
Kev sib xyaw ua ke corona kev ua tiav rau cov kab txheej ua rau cov kab uas cuam tshuam tseem ceeb thiab ntsuas tau zoo:
1. Tshwj Xeeb Ntawm Txheej Txheej Txheem Ua Haujlwm:Nrog rau cov nplaim hluav taws xob zoo dua, ua kom cov txheej zoo sib xws yam tsis muaj kev tsis txaus siab tsis meej xws li pinebomerations. Qhov kev sib txig no yog qhov tseem ceeb rau kev ua tiav kev paub tab thiab rov ua dua tshiab hauv tshuab hluav taws xob thoob plaws txhua lub hlwb.
2. Txhim kho Adhesion lub zog:Cov nyhuv sib xyaw ua ke ntawm kev ntxuav, etching, thiab kev ua haujlwm tsim ib qho muaj zog xws li lwm yam thiab tshuaj lom neeg nruab nrab ntawm cov khoom siv txheej. Qhov no drastically txo qhov kev pheej hmoo ntawm kev ziab thaum ziab, calendering, thiab rov ua dua tshiab {1} {tso mus ncig.
3. Cov txheej txheem nce ntxiv thiab tawm:Los ntawm daws teeb meem wettabiles, cov tuam ntxhab tuaj yeem nce lawv txoj kab nrawm yam tsis muaj kev sib txawv. Qhov tseem ceeb tshaj, qhov txo qis hauv cov txheej tsis sib xws ncaj qha txhais lus tau yooj yim thiab cov kev cuam tshuam hauv qab.
4. Txhim kho ntev - sij hawm kev cia siab thiab kev nyab xeeb:Cov nplaum muaj zog tiv thaiv cov khoom siv ntawm cov khoom muag. Cov nplais uas xoob tuaj yeem ua rau muaj kev voj voog luv luv, muaj peev xwm fade, thiab thermal khiav tawm. Ib qho zoo -} kho electrode yog kev nyab xeeb thiab muaj lub neej ntev dua.
5. Qhuav, daws - dawb, thiab eco- tus phooj ywg:Tsis zoo li cov tshuaj lom neeg cov tshuaj nplaum lossis cov nplaim hluav taws yog qhov qhuav, tsis - Hu ua. Nws ntxiv tsis muaj cov kuab tshuaj, vocs, lossis kub ntxhov siab rau lub substrate, ua rau nws cov kev xaiv huv thiab muaj kev nyab xeeb rau cov gigafactories niaj hnub no.
Vim li cas "kev ntseeg tau" yog qhov tseem ceeb
Nyob rau hauv cov ntsiab lus ntawm siab -} ntaub ntim roj teeb, muaj kev cia siab tsis yog ib qho zoo- nws yog qhov tsim nyog. Ib txoj kev kho Corona txhim khu kev qha txhais tau tias:
Cov Khoom Siv Hluav Taws Xob Tsis Ncaj Ncees:Khoom siv hluav taws xob ruaj khov ua kom muaj kev kho kom zoo sib xws thoob plaws lub web dav thiab dhau kev sib tw ntev.
Kev Tu Me Nyuam Tsawg:Cov qauv tsim hluav taws xob khov kho thiab ozone kev tswj hwm kev tswj hwm kom tau nce thiab txo qhov xav tau ntawm cov khoom nres nquag.
Web - Tus phooj ywg ua haujlwm:Lub tshuab tau engineered kom zam kev drawbacks zoo li rov qab {{}} pinning kev kho lossis "lub vev xaib mus rau tus yob, uas tuaj yeem ua cov teeb meem ua haujlwm.
Seamless kev sib xyaw:Cov kws kho mob niaj hnub yog tsim los ua kom yooj yim rau hauv cov kab tshiab lossis cov txheej txheem ua tiav nrog kev tswj hwm tshuab thiab saib xyuas 4.0 kev ua raws.

Raws li qhov kev thov rau lub zog siab dua, them nyiaj sai dua, thiab ntau lub zog ruaj khov ntxiv, txhua theem ntawm cov txheej txheem tsim khoom yuav tsum tau ua kom zoo. Corona kev kho saum npoo av tsis yog ib qho ntxiv uas yog ib qho ntxiv. Nws yog lub hom phiaj thev naus laus zis rau kev tsim cov siab - Cov hluav taws xob zoo. Los ntawm kev ntseeg tau txhim kho cov nplaum thiab kev sib xyaw ntawm cov neeg ua haujlwm canhode thiab corona cov kws ua haujlwm zoo dua, thiab roj teeb loj dua uas tau tsav peb lub sijhawm hluav taws xob.
