PURPOSE:To improve the high rate discharge characteristic and enhance the weight efficiency and volume efficiency by winding a group of electrodes flatly using a conductive lattice of specific length, and forming electrode group tab and intercell joints on a straight line solidly as in a single piece. CONSTITUTION:A positive 3 and a negative 6 electrode plate are formed by filling expand lattices, which are conductive and have current collecting function, with respective electrode active substances, wherein the lattice shall have an appropriate length to suit the battery capacity. The two electrode plates are separated by a separator 8, wound flastly, and accommodated in a battery jar 10, so that the voids at the corners are small and the volume efficiency is high. Electrode terminals are furnished at the two electrode plates with the aid of tabs, and each group of electrodes is coupled through a battery jar partition wall 11 via an intercell joint 7. The positive electrode terminal 1, negative electrode terminal 4, and intercell joint 7 are arranged on a straight line. This does not require any special joint member, and the discharge characteristic and weight efficiency are enhanced. |
