Method for manufacturing electrode for lithium ion secondary cell
Abstract:
The method for manufacturing an electrode for a lithium ion secondary cell proposed herein includes: a step of pattern-coating a binder liquid 21d on a current collector 12 and forming a binder coat layer 16, and a step of supplying granulated particles 32 onto the binder coat layer 16. The binder coat layer 16 is intermittently formed on the current collector 12 so that band coated portions 16a and band uncoated portions 16b are alternatingly adjacent to each other. The width t1 of the coated portions 16a, the width t2 of the uncoated portions 16b, and the average particle diameter R of the granulated particles 32 satisfy the following relationships: 0.53R≤t1≤10R; 0.66R≤t2≤10R; and 0.2≤t1/t2≤3.75.
