Txhim Kho Cov Roj Teeb Kev Ua Tau Zoo: Lub Luag Haujlwm Tseem Ceeb ntawm Corona Kev Kho Mob Hauv Cov Khoom Hluav Taws Xob hauv Cov Hluav Taws Xob Txheej Cov Qauv Adhesion
Lub ntiaj teb kev sib koom ua ke rau hluav taws xob, los ntawm cov tsheb hluav taws xob, EVS) rau cov kev xav tau ntawm lithium {1} ion roj teeb. Ntawm lub siab lub plawv ntawm txhua qhov siab- Kev ua tau zoo roj teeb tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob tam sim no. Ua tsis tiav ntawm no tuaj yeem ua rau kev puas tsuaj loj hauv lub peev xwm, lub zog, thiab thiav. Nov yog qhov twg corona kho cov thev naus laus zis ua qhov tseem ceeb, precision cuab tam rau kev txhim kho cov teeb meem roj teeb zoo dua.
Adhesion kev sib tw hauv roj teeb raug
Ib lub roj teeb khib nyiab muaj cov slurry -} cov duab hlau ua kom muaj zog (piv txwv li ntawm cov khoom siv hlau nplaum (aluminium rau anto hlau. Daim ntawv cog lus ntawm cov slurry no thiab cov ntawv ci cov ntawv ci yuav tsum yog qhov muaj zog tshwj xeeb.
Cov kua nplaum tsis zoo hauv:
Delamination:Cov txheej txheej sib cais los ntawm cov ntawv ci thaum lub caij cycling, ua rau kev poob sai hauv kev muaj peev xwm.
Nce sab hauv kuj:Tsis zoo hu rau hluav taws xob tiv thaiv hluav taws xob, txo qis zog tawm thiab ua rau muaj zog siv zog.
Kev voj voog lub neej lub neej txo qis:Raws li cov khoom sib xyaw, lawv tau ua hluav taws xob tsis ua haujlwm, ua kom luv lub roj teeb siv lub neej siv tau.
Raug tej yam tsis xws luag:Kev sib raug zoo uas tuaj yeem ua rau tawg lossis tev thaum lub sijhawm calendering (compression) thiab slitting txheej txheem.
Lub hauv paus ua rau ntawm cov nplaum tsis zoo yog feem ntau qislub zog saum npoontawm pristine hlau ntawv ci. Thaum lawv yuav saib kom du, cov ntawv no muaj cov tshuaj tsis muaj tshuaj tsw qab uas tsis tau txais qhov ntub dej ntub dej, ua rau kev sib tsoo ntawm lub cev ntub dej.
Corona kev kho mob yog dab tsi?
Corona kev kho yog qhov zoo -}}} tsim, atmospheric ntshav cov txheej txheem hloov kho deg. It utilizes a high-frequency, high-voltage electrical discharge to ionize the air surrounding the electrode foil, creating a cloud of reactive plasma species-including ozone, oxygen ions, and free radicals.
Raws li cov ntawv ci hla ncaj qha dhau ntawm cov pob txha caj qaum hauv qab ntawm cov chaw nres tsheb Corona, qhov no tswj hwm lub tshuab hluav taws xob "
1. Cov Kev Ua Kom Zoo:Cov ntshav tawg cov roj av cov roj av ntawm cov ntawv nyiaj saum npoo, tsim cov chaw siab tshaj plaws.
2. FunctionalFunctionalization:Cov txheej txheem reactive tam sim ntawd daim ntawv cog lus sib haum nrog cov pa roj oxygen (xws li carbonyl, hydroxyl, thiab cov pab pawg carboxyl) mus rau saum npoo.
Yuav ua li cas Corona Kev Kho Mob Txhim Kho Txheej Txheej
Qhov kev hloov pauv saum npoo no muab cov txiaj ntsig muaj txiaj ntsig rau cov khoom siv hluav taws xob:
1. Dramatically nce nto zog:Cov Lus Qhia Txog Pawg Polar ua rau ib zaug - inert nto hydrophilic thiab energetically recen. Qhov no tso cai rau cov kuab tshuaj - raws li lossis ntub lub ntsej muag tusyees, sib sau ua kom muaj kev sib cuag heev. Lub zog saum npoo yog qhov tseem ceeb ntawm tus neeg tsav tsheb ntawm muaj zog adchesion.
2. Txhim kho cov neeg kho tshuab cuam tshuam:Xauv:Ntawm theem me me, kev kho Corona kev kho Etches cov ntawv nyiaj, tsim NANA {0} {roughness. Qhov chaw nce npoo ntxiv muab cov ntsiab lus ntxiv "rau cov binder polymers nyob rau hauv lub slurry mus tuav mus rau hauv cov neeg kho tshuab, ua kom zoo dua kev siv kho tshuab.
3. Txhim kho cov tshuaj sib xyaw ua tau zoo:Cov pab pawg ua haujlwm polar ua haujlwm raws li cov kab ke tshuaj lom neeg, tsim kom muaj kev sib tw thib ob (cov ntawv cog lus thib ob nrog cov ntawv sib txuas lus hauv cov slurry. Qhov no tsim ib cohesive interface ntau dua li ib tug yooj yim kho txheej txheem txheej txheem.
4. Cov txheej txheem txheej txheem zoo nkauj: nrog cov npluav me me, cov slurry ntws tau zoo li pinebes, agglomerations, lossis dreaded "{}} ntub". Qhov kev sib txuam no yog qhov tseem ceeb rau kev faib tawm tam sim no thiab roj teeb ua tau zoo.
Cov ntsiab lus tseem ceeb rau cov tub txhab roj teeb
Kev sib xyaw ua ke ntawm Corona cov tub rog mus rau hauv electrode txheej kab muaj cov txiaj ntsig kev sib cav thiab cov khoom lag luam:
Boosted lub zog ntom ntom:Cov nplaum muaj zog ua rau siv cov txheej txheej tuab uas tsis muaj kev pheej hmoo ntau, ncaj qha rau cov khoom siv nquag thiab yog li lub xovtooj ntawm lub peev xwm (mah / g).
Txuas lub neej ncua sijhawm:Los ntawm kev tiv thaiv cov khoom siv tsis taus thiab tswj hwm qis hauv sab hauv kev tawm tsam, roj teeb khaws lawv lub peev xwm rau ntau tus nqi rau ntau lub sijhawm.
Txhim kho nrawm -} parging muaj peev xwm:Ib lub teeb tsa hluav taws xob zoo nrog kev tiv thaiv tsawg dua yog qhov tseem ceeb rau kev tuav lub siab currents koom nrog kev them nyiaj sai uas tsis muaj kev nyuaj siab.
Nce ntau cov lus qhia:Txo cov ntawv los ntawm cov teeb meem tsis xws luag thiab txhim kho cov txheej txheem ua kom haum rau kev tsim kho siab dua thiab tus nqi qis.
Eco {{0} Tus txheej txheem phooj ywg:Corona kev kho yog qhuav, daws - txheej txheem dawb uas siv cov hluav taws xob thiab huab cua ua ke ntawm kev lag luam roj teeb.
Kev sib xyaw thiab cov txheej txheem tswj
Niaj hnub nimno Corona cov kws kho mob niaj hnub no tau tsim rau kev sib xyaw ua ke rau hauv kev sib xyaw ua ke rau hauv kev sib xyaw ua ke. Cov ntawv tseem ceeb zoo li lub zog, zaus, thiab hluav taws xob tau raug tswj xyuas thoob plaws tag nrho cov web dav tsis muaj kev puas tsuaj rau cov ntawv ci tag nrho. The non-thermal nature of the process also means there is no heat-induced degradation of the foil or pre-applied coatings.
Tag
Hauv kev sib tw ntau dua rau qhov zoo dua, muaj kev nyab xeeb dua, thiab ntev dua- kav roj teeb, ua rau txhua theem ntawm cov txheej txheem tsim khoom yog qhov tseem ceeb. Corona kho tsis yog ib qho kev xaiv ua xwb; Nws yog lub khoos phis tawj tsim thev naus laus zis ua kom tiav cov qib ntawm lub electrode yuav tsum los ntawm-} cov ntawv thov. Los ntawm cov tswv yim hloov kho cov khoom saum npoo ntawm cov neeg sau ntawv tam sim no, paving txoj hauv kev rau cov roj teeb uas tau txais lub zog loj dua, thiab kev cia siab ntau dua, thiab kev cia siab thiab tsis txaus ntseeg tau.
