Abstract
A multilayer battery module includes first cylindrical battery cells arranged standing in lateral and longitudinal directions into a matrix form; second cylindrical battery cells arranged standing on the first cylindrical battery cells with each one of the second cylindrical battery cells in a one-to-one relationship with a corresponding one of the first cylindrical battery cells; and a heatsink of high thermal conductivity between the first and second cylindrical battery cells. The first and second cylindrical battery cells and are disposed so that positive electrode terminals and negative electrode terminals face each other with the heatsink being interposed therebetween. A portion of the heatsink facing each respective positive electrode terminal is recessed to form a heat and gas discharge path, and a portion of the heatsink facing each respective negative electrode terminal contacts the respective negative electrode terminal to form a heat dissipation path.
