PLANETARY MIXER AND PRODUCTION METHOD OF ELECTRODE PASTE FOR LITHIUM ION SECONDARY BATTERY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a planetary mixer capable of achieving mixing, agitating and kneading without the adhesion and fixing of a material to a tank in the production of medium and high viscosity materials such as an electrode paste for a lithium ion secondary battery.SOLUTION: The rotation and revolution of a plurality of agitation blades 6 are performed in a tank 7. The liquid contact part of the agitation blades 6 has a dynamic friction coefficient of stainless steel or a ceramic material. A coat layer 16 coated with diamond-like carbon (DLC) is formed on the liquid contact part of the tank and has a dynamic friction coefficient of the diamond-like carbon lower than that of stainless steel and the like.
