Abstract
Official abstract text for this publication.
Provided are a method for producing a battery member and a device for producing a battery member that make it possible to integrate layers of the battery member by way of a roll press, and make it possible to achieve favorable performance of the battery member. A method is for producing a battery member having a positive electrode sheet including at least a positive electrode current collector and a negative electrode sheet including at least a negative electrode current collector, at least one of the positive electrode sheet and the negative electrode sheet having an electrolyte layer laminated thereon.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for producing a battery member having a positive electrode sheet including at least a positive electrode current collector and a negative electrode sheet including at least a negative electrode current collector, at least one of the positive electrode sheet and the negative electrode sheet having an electrolyte layer laminated thereon, the method comprising successively: a preliminary heating step including heating the positive electrode sheet and the negative electrode sheet to a predetermined temperature; and a roll pressing step including integrating the positive electrode sheet with the negative electrode sheet, wherein in the roll pressing step, a roll pressing temperature for the positive electrode sheet and a roll pressing temperature for the negative electrode sheet are set to different temperature ranges. 2 . The method according to claim 1 , further comprising: after the roll pressing step, a stepwise cooling step including cooling in a stepwise manner the positive electrode sheet and the negative electrode sheet that have been integrated with each other. 3 . The method according to claim 1 , wherein in the preliminary heating step, a preliminary heating temperature for the positive electrode sheet and a preliminary heating temperature for the negative electrode sheet are set to different temperature ranges. 4 . A device for producing a battery member having a positive electrode sheet including at least a positive electrode current collector and a negative electrode sheet including at least a negative electrode current collector, at least one of the positive electrode sheet and the negative electrode sheet having an electrolyte layer laminated thereon, the device comprising: a first heater that heats the positive electrode sheet; a second heater that heats the negative electrode sheet; and a roll press that is disposed after the first heater and the second heater, and that integrates the positive electrode sheet with the negative electrode sheet, wherein in the roll press, a heating temperature for the positive electrode sheet and a heating temperature for the negative electrode sheet are set to different temperature ranges. 5 . The device according to claim 4 , further comprising: a heat retainer disposed after the roll press. 6 . The device according to claim 4 , wherein a temperature of the first heater and a temperature of the second heater are set to different temperature ranges.
