▎ 摘  要

NOVELTY - Processing electrode material, comprises (a) adding the electrode active material and conductive agent into the granulator, and using medium speed stirring at 1000- 2000 revolutions per minute, the middle speed stirring time is 5-15 minutes to obtain the uniform mixed material, and testing the loose density of the mixture material is BD0, (b) adding agglomerant to mixed material, and using 5000-7000 revolutions per minutes of high speed stirring, high speed stirring time is 3-10 minutes to obtain the fiberized material, testing the loose density BDt of the fibrillated material when the stirring time is t, where BDt is less than < 50 %, and (c) scattering the fibrosis material at low speed of 100-500 revolutions per minute, the low speed stirring time is 5-10 minutes to obtain the uniform particle electrode material. USE - The method is useful for processing electrode material, which is used in lithium-ion battery (claimed). ADVANTAGE - The method: solves the problem that the electrode film is hole or edge is not uniform, and improves the manufacturing efficiency and electrochemical performance of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for processing electrode pole piece, comprising rolling the electrode material into dry film, then the dry film is folded into a coil, then the dry film by flat heat pressing is attached to the two sides of the current collector to obtain the dry electrode pole piece, where the electrode material is the processing method to obtain the product. DESCRIPTION OF DRAWING(S) - The drawing shows of a processing method of electrode material (Drawing includes non-English language text).
