All-solid battery element

摘要

The all-solid battery element of the invention is designed to simultaneously satisfy the increased contact area of electrodes with an electrolyte layer and the decreased thickness of the electrolyte layer. The all-solid battery element of the invention has at least one unit cell. The unit cell includes: a cathode having a cathode active material; an anode having an anode active material; and a solid electrolyte layer that is interposed between and is in contact with both the cathode and the anode. In the at least one unit cell, the solid electrolyte layer has a specific array structure of arranging at least part of the cathode and at least part of the anode in an alternate manner or in a zigzag manner.
