Abstract
A battery device having a high discharge current value and a high current collecting efficiency at electrodes. A first active material is applied on a first current collecting unit avoiding one end and/or the other end of the width direction to form an anode, and a second active material is applied on a second current collecting unit avoiding one end and/or the other end of the width direction to form a cathode. The current generated at the electrodes formed by winding the anode and cathode via separators is output through the parts uncoated with the first active material of anode and the parts uncoated with the second active material of cathode, so as to realize the battery device having a high discharge current value and a high current collecting efficiency at the electrodes.
