Title:
IMIDE-BASED POLYMER SOLUTION
Document Type and Number:
Japanese Patent JP2018046018
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an imide-based polymer solution which can be used for manufacturing a lithium secondary battery electrode having superior safety, and a high discharge capacity and good cycle characteristics by enhancement of an adhesive property between a porous layer and an active material layer.SOLUTION: An imide-based polymer solution for forming an ion permeable porous layer on an electrode active material layer surface comprises a solvent containing an amide-based solvent and an ether-based solvent. The amide-based solvent is a good solvent to an imide-based polymer, and the ether-based solvent is a poor solvent to the imide-based polymer.SELECTED DRAWING: None
