Title:
非水電解液二次電池用負極の製造方法、および非水電解液二次電池の製造方法
Document Type and Number:
Japanese Patent JP6683159
Kind Code:
B2
Abstract:
A method of manufacturing a negative electrode for a non-aqueous electrolyte secondary battery includes the following. A negative electrode composite material layer including a planar region and a side-surface region is formed. An application material is prepared by mixing heat-resistant particles, thermoplastic resin particles, and a solvent. A planar coating film is formed by applying the application material to the planar region and a side-surface coating film is formed by applying the application material to the side-surface region. At least some of the thermoplastic resin particles are molten into a melt by heating the planar coating film at a temperature not lower than a melting point of the thermoplastic resin particles. A negative electrode is manufactured by drying the planar coating film containing the melt and the side-surface coating film containing the thermoplastic resin particles at a temperature lower than the melting point of the thermoplastic resin particles.
