Hauv kev tsim cov txheej txheem ntawm lithium{0}} ion roj teeb, qhov sib xws thiab sib xws ntawm cov electrode slurry cuam tshuam rau kev ua haujlwm ntawm electrochemical ntawm lub roj teeb. Cov txheej txheem dispersion yog qhov tseem ceeb ntawm cov txheej txheem thermodynamically tsis ruaj khov, thiab nws tsis yooj yim los xyuas kom meej qhov ruaj khov thiab tsis sib xws ntawm cov khoom siv theem hauv cov kua dispersion nruab nrab.

Siv lub lithium ion roj teeb aqueous tsis zoo electrode slurry ua piv txwv. Nws yog ib tug multi-element dispersion system nyob rau hauv uas lub dispersed theem yog cov khoom theem khoom xws li graphite thiab conductive tus neeg sawv cev, thiab cov dispersion nruab nrab yog ib tug ua kua theem ntawm dej, CMC thiab SBR. Graphite yog ib yam khoom uas tsis yog -polar, nws tsis yooj yim rau nqus dej, thiab nws tsis yooj yim rau disperse hauv dej. Cov kab mob sib kis tau yooj yim rau rov- sib sau ua ke tom qab sib cais hauv dej; polarity ntawm conductive tus neeg sawv cev yog txawv heev; thaum dej, CMC thiab SBR yog tag nrho cov polar tshuaj. Thaum npaj cov electrode slurry, yog tias cov khoom siv tsis tuaj yeem sib kis tau zoo ib yam, qhov sib xws ntawm cov electrode slurry yuav tsis zoo, uas ua rau tsis ruaj khov electrochemical kev ua tau zoo ntawm cov roj teeb npaj. Tam sim no, feem ntau siv dispersion txoj kev nyob rau hauv cov txheej txheem ntawm kev npaj ntawm electrode slurry yog ua kom yooj yim mechanical stirring, siv ib tug stirring hniav uas tau tsav los ntawm lub cev muaj zog mus do cov electrode slurry tusyees. Txawm hais tias txoj kev no yooj yim heev thiab yooj yim rau kev khiav lag luam, nws yog ib qho nyuaj rau ua kom cov khoom nyob rau hauv lub electrode slurry tusyees faib, thiab cov slurry nyob rau hauv lub ces kaum tuag tsis tau txawm yuav stirred nyob rau hauv tag nrho, los yog nws tag nrho tshem tawm particle agglomeration.

Kev kho ultrasonic dispersion tuaj yeem ua ke nrog cov neeg kho tshuab nplawm hauv cov duab ua ntej, thiab cov electrode slurry yog mechanically stirred thiab dispersed ua ntej lossis tom qab siv ultrasonic dispersion kho. Ultrasonic dispersion kev kho mob muaj txiaj ntsig zoo hauv kev tshem tawm particle agglomeration. Mechanical stirring tuaj yeem ua tiav ntau yam ntawm electrode slurry txaus. Kev sib xyaw ua ke ntawm ob yuav ua rau cov nyhuv dispersion thiab kev ua haujlwm zoo tshaj plaws. Txoj kev nyiam electrode slurry dispersion yog: mechanical stirring ua ntej electrode slurry txheej, thiab tom qab ntawd ultrasonic dispersion kho.

Thaum ultrasonic siv los disperse electrode slurry, qhov kub ntawm cov electrode slurry yog khaws cia ntawm 30 degree mus rau 40 degree. Nyob rau hauv qhov kub thiab txias, cov nyhuv ultrasonic cavitation zoo dua.

Cov txiaj ntsig

Cov txiaj ntsig zoo ntawm txoj kev dispersion ntawm electrode slurry ntawm tam sim no invention yog:

● The electrode slurry is subjected to ultrasonic dispersion treatment, and the ultrasonic cavitation effect can be used to make the electrode slurry eliminate particle agglomeration and uniformly disperse;

● There is no dead corner of dispersion with ultrasonic dispersion treatment.

● After the electrode slurry is coated with ultrasonic dispersion treatment, the obtained coating has better uniformity, which is beneficial to improve the electrochemical performance of the battery.
