what's the importance the fineness of battery slurry to lithium ion battery?


what is battery slurry?

Lithium ion battery slurry is composed of active electrical material, conductive agent and other solid particles dispersed in the binder solution form. Coating active material and conductive agent and other solid components should be small particles dispersed in a solvent, can not be displayed in the form of granular film.


what's the disadvantage if battery slurry is not refined as fine as possible?

electric material not refined will directly result in battery consistency is poor. and even big grandular substance will result in lithium ion battery appearance scratch and broken.


how to measure lithium ion battery slurry finess?

generally, lithium battery industry is using scraper fineness to measure slurry fineness, which unit is μm.
