1. Cov ntsiab lus tseem ceeb
Nyob rau hauv kev npaj ntawm lub roj teeb hluav taws xob, cov txheej txheem ntawm ultrasonic Atomant txau tuaj yeem muab faib ua 4 kauj ruam tseem ceeb:
1.1 Kev npaj ntawm eleces: sib xyaw cov khoom siv ua haujlwm (xws li nmpers (xws li nmpers (xws li nmpers (xws li nmp
1.2 slurry xa thiab atomization: cov slurry yog xa mus rau ultrasonic atomization taub hau dhau los ntawm kev ua twj ua ke. Lub piezoelectric chrrator ntawm lub taub hau atomization lub taub hau vibrates (feem ntau 20kHz), ua kom muaj zog ntawm cov taub hau ntawm 1 - 30 xo hluav taws xob tau tuaj yeem hloov kho los ntawm zaus: Ntau zaus ntawm cov tee dej).
1.3 Directional Kev xa tawm ntawm cov dej ntws: lub atomized slurry slurry cov roj (xws li cov chaw ntim khoom tam sim no (cov neeg sau khoom siv tam sim no
1.4 Txheej Txheej Tsim thiab ziab: Lub tee dej nrawm nrawm nrawm los tsim cov txheej txheem txuas ntxiv, kom tshem tawm cov kuab tshuaj txuas ntxiv nrog cov tuab tuab (feem ntau 5 - 200 microns).
2. Cov ntsiab lus zoo piv rau ib txwm muaj hluav taws xob tshuab
Hauv roj teeb elemrode kev tsim khoom, xws li cov hniav txheej sib xyaw thiab cov khoom siv tsis zoo, thiab tsis muaj zog yoog raws siab cov ntsiab lus siab. Qhov zoo ntawm ultrasonic Atomization Txau yog tshwj xeeb tshaj yog muaj tshwj xeeb:
Yam | Ultrasonic Txau | Pa Tus Kws Kho Mob Hniav / Qhov Txheej Txheem |
Cov Txheej Txheem Txheej | Cov tee dej tau zoo thiab muaj cov txheej txheej, cov txheej tuab tuab, cov txheej tuab tuaj yeem tswj tau tsis raug xws li "ntug tuab" thiab "Pinholes" | Raug rau kev hloov pauv ntawm slurry viscosity, thickness txawv yog feem ntau ± 5% - 10%, thiab cov khoom siv tau yooj yim rau ntawm ntug |
Cov Khoom Siv Siv | Cov tee dej yog qhov tseeb heev, yuav luag dawb ntawm drift, thiab kev siv tus nqi nce mus txog 85% 95% (tus nqi ntawm cov khoom siv nquag, yog li no kom zoo dua) | Lub slurry yog qhov yooj yim nyob thiab drip, thiab tus nqi siv tsuas yog 50% - 70% |
Daim Txheej Thickness tswj | Ultra - nyias txheej (nqis rau 1 micron) tuaj yeem ua tiav nrog cov roj teeb tsis tu ncua (txiav lub zog loj me roj roj teeb (nyias muaj zog diffusion paths) | Nws yog qhov nyuaj los npaj ultra - nyias txheej txheem <10 microns, thiab cov tuab tuab kho tau ntau yog nqaim |
Slurry kev yoog raws | Tuaj yeem tswj cov ntsiab lus muaj zog (>> 60%), siab viscosity (> | Tsis zoo adaptility rau cov ntsiab lus zoo / siab viscosity slurry, yooj yim rau txhaws qhov chaw nres nkoj coating |
Kev puas tsuaj rau cov neeg sau khoom tam sim no | Tsis muaj kev sib cuag tshuab (lub taub hau atomizer tsis hu rau tus sau tam sim no), tsim nyog rau cov neeg khaws nyiaj tam sim no (xws li tooj liab ntawv ntawv ci hauv qab 6μm) | Tus scraper yog sib cuag ncaj qha nrog tus sau tam sim no, uas tuaj yeem yooj yim khawb cov nyias rawg. |
Daim ntawv thov ntawm ultrasonic afization txau hauv cov tub sab tau hloov mus los ntawm chav kuaj kom loj - kev tsim khoom, thiab cov cwj pwm tseem ceeb muaj xws li:
3.1 lithium - Ion roj teeb hluav taws xob
Cov ntaub ntawv ntawm cov khoom lag luam: NCM), Lithium Iron phosphate (LFP), thiab lwm yam ntawm txhuas ntawv ci, tshwj xeeb tshaj yog haum rau kev kub siab (xws li NCM811) - Cov khoom siv no muaj cov khoom siv tsis zoo heev, txwv tsis pub nws yooj yim los ua rau thermal khiav tawm vim yog qhov tsis xwm yeem cov kev tsis xwm yeem.
Cov ntaub ntawv tsis zoo rau hluav taws xob: txheej graphite thiab silicon - cov ntaub ntawv hauv qab tooj liab cov hluav taws xob yog qhov yooj yim txo qis tawg thaum ncig).
Cov txiaj ntsig zoo: Txhim kho qhov sib txawv ntawm cov hluav taws xob ntom ntom "thaum txo qis" polarization promomenon thiab expending lub neej roj teeb (tuaj yeem nce li 20% - 30%).
3.2 roj cell catalyst txheej txheej txheej
Cov tub ntxhais tivthaiv roj (xws li cov roj av roj hluav taws xob ("membrane)", yuav tsum tau catalinum - Ultrasonic omron catalalt slurry (platinum particle kev siv nrog ntau dua 60% (kev ua ib txwm muaj 30%) 40%), uas tau txo tus nqi.
3.3 Nrig - Lub xeev roj teeb electrolyte txheej
Cov electrolyte ntawm cov khoom khov - Lub xeev roj teeb (xws li sulfide thiab oxide khoom electrolytes) yuav tsum tau ua ib daim nruam cov txheej sib nraus (1 - 5 microns) nyob rau hauv electrode nto. Ultrasonic omarization tshuaj tsuag tuaj yeem zam cov txheej txheem "ntawm cov txheej txheem ib txwm muaj, cov txheej txheem electrolyte, dawb, thiab txhim kho ion ua tau zoo.
