Abstract: A plurality of slit-shaped space regions are provided on an anode active material layer on a front surface or a rear surface of an anode sheet so as to reach end planes to make it easy to inject an electrolyte into a scrolled body or a jelly roll of a non-aqueous electrolyte secondary battery through the slit-shaped space regions.

Abstract: A secondary battery according to the present invention includes a case for accommodating an electrode element therein and a conductive lid element for closing an open end of the case. A plurality of electrode terminals extend from the top and bottom of the electrode element. The plurality of electrode terminals extending from the top of the electrode element are electrically connected to one end of a collecting terminal with a metallic grommet. The other end of the collecting terminal is connected to the back of the lid element, and thus the plurality of electrode terminals are electrically connected to the lid element through the grommet and the collecting terminal.
