Title:
二次電池
Document Type and Number:
Japanese Patent JP7133046
Kind Code:
B2
Abstract:
To provide a secondary battery that can be mounted on a substrate and can easily select a voltage to be output in manufacture and a manufacturing method thereof. A secondary battery in which small cells with substantially the same form are stacked and whose voltage to be output is easily selected in manufacture by changing the number of stacked layers is manufactured. In the cell, an electrolytic solution including a spacer and a polymer is used to keep at least a certain distance between the positive electrode active material layer and the negative electrode active material layer with the spacer. Furthermore, the electrolytic solution is made to gelate by the polymer to be an electrolytic solution that can be formed in the form of a sheet. Furthermore, the positive electrode active material layer and the negative electrode active material layer are formed using a printing method typified by screen printing.
