METHOD FOR MANUFACTURING A BATTERY

摘要

A method for manufacturing a battery provided with an electrode sheet including a separator layer integrally formed on an active material layer. The method includes: a coating step in which a liquid dispersion in which resin particles are dispersed is coated onto the active material layer, forming an undried separator layer; and a heat drying step in which the undried separator layer is dried by heating, forming the separator layer. The heat-drying step is a step for heat drying the undried separator layer at a temperature within a surface melting temperature range in which a surface portion of the resin particles melts, but a center portion does not melt.

1. A method for manufacturing a battery provided with an electrode sheet including:
an active material layer made of active material particles; and a separator layer integrally formed on the active material layer and made of thermoplastic resin particles, wherein the method includes: a coating step of applying a dispersion liquid in which the resin particles are dispersed to the active material layer to form an undried separator layer; and a heat-drying step of drying the undried separator layer by heating to form the separator layer, wherein the heat-drying step includes drying the undried separator layer by heating at a temperature within a surface melting temperature range in which each of the resin particles does not melt at a center portion but melts at a surface portion.
