AI Technical Summary

Technical Problem

Existing slurry mixing devices for secondary battery electrodes face issues with non-uniform composition due to splashing and adherence of slurry to the lid, leading to variations in the active material composition and reduced worker convenience.

Method used

A slurry mixing mixer equipped with a first stirring body for high-speed mixing, a second stirring body for low-speed mixing, and a scraper on the lid to collect and incorporate adhering slurry, ensuring uniformity by integrating it back into the mixture.

Benefits of technology

Ensures uniformity of the slurry composition by effectively scraping and reintegrating adhering slurry, maintaining consistency in the active material layer and enhancing electrode performance of secondary batteries.

Abstract

A slurry mixing mixer is provided. The slurry mixing mixer comprises: a container body containing a slurry of a mixture of liquid and powder materials; a lid covering the container body; a first stirrer installed on the lid to move up and down and rotate to mix and disperse the slurry; a second stirrer installed on one side of the first stirrer on the lid to rotate and revolve to mix the slurry of the mixture within the container body; and a scraper installed on the rotation axis of a rotor driving the second stirrer to scrape the slurry adhering to the lower surface of the lid.
