MANUFACTURING METHOD OF ELECTRODE AND WET GRANULES |
摘要 |
A manufacturing method of an electrode according to the invention includes: a process of forming wet granules by stirring a mixture of an electrode active material, a binding material, and a solvent; and a process of forming an electrode material layer on a current collector by rolling the wet granules. The process of forming the wet granules includes: a process of granulating the electrode active material by stirring the mixture at a first stirring speed; and a process of stirring the granulated electrode active material at a second stirring speed that is faster than the first stirring speed so as to be refined to an average particle size of 400 µm or smaller. A stirring time at the second stirring speed is shorter than a stirring time at the first stirring speed and is shorter than 5 seconds. |
