The disclosed technology relates to a battery utilizing a dampening layer to prevent a failure of the battery. The battery includes an enclosure, a set of electrodes enclosed within the enclosure, and a dampening layer disposed within the set of electrodes. The dampening layer partitions the set of electrodes into a first subset of electrodes and a second subset of electrodes. The dampening layer is configured to absorb a mechanical impact on the enclosure to prevent a failure of at least one of the first subset of electrodes and the second subset of electrodes. The dampening layer may be formed at least one of a polymer, metal, and ceramic.

Provided is a secondary battery including a power generation unit including a positive electrode layer, a negative electrode layer, a porous separator, and an electrolytic solution. The negative electrode layer is a dissolution-deposition electrode. When viewed in plan view, a functional region, identified as a region where the positive electrode layer, the negative electrode layer, the electrolytic solution, and the porous separator overlap, is divided into power generation regions and a linear non-power generation region demarcating each power generation region. The power generation regions have a value α of 30 or less, the value α being defined by the equation: α=ΦP/wt, wherein Φ represents an area equivalent diameter (mm) per region of the power generation regions, P represents a thickness (mm) of the negative electrode layer, w represents a line width (mm) of the non-power generation region, and t represents a thickness (mm) of the porous separator.
