Patent ID: 11843128

Abstract:
A cell module includes a plurality of cells that each have a cylindrical shape and include a positive-electrode terminal and a negative-electrode terminal disposed on one end of the cell. One of the terminals is located at a center, and the other terminal is located on a circumferential edge and is electrically connected to a side surface of a tube of each of the cells, a connection intervening member mounted on the other terminal includes a tab extending along the side surface of the tube and electrically connected to the side surface, and a hole that causes the center of the one end to be exposed. The plurality of cells make up a cell block where the one ends are oriented in an identical direction, and cells adjacent to each other are aligned in rows, on the one ends of the plurality of cells, a plate having electrical insulating properties is disposed, the plate is provided with a hole that causes the one end of each of the cells to be exposed and is further provided with a plurality of conductive members on a surface of the plate distant from the cells, the conductive members extend along the rows of the cells aligned, two of the conductive members are disposed for each cell block and include terminal connectors electrically connected to terminals, having identical polarity, of the cells in each cell block, and the other terminals are connected with the terminal connectors through the connection intervening member.
