Document Type and Number:
Japanese Patent JP3091885
Kind Code:
B2
Abstract:
PURPOSE:To prevent electrochemical deterioration by connecting a resistor having predetermined resistance in parallel to a cell between a positive electrode container and a negative electrode container in a single cell. CONSTITUTION:A connection means 2 is provided between a positive electrode container 9 and a negative electrode container 6 of each single cell and connected in parallel to the cell. The connection means is an element having resistance lower than internal resistance of the cell at a room temperature while having higher resistance than the internal resistance of the cell at a cell operation temperature. With this constitution, electrode reversing due to current flow into the cell at a room temperature can prevent a solid electrolyte 11 from electrochemical deterioration such as generation of dendrite.
