Abstract
A secondary battery comprises a porous body, a positive electrode and a negative electrode. The porous body has an electrolyte region which is loaded with a solid electrolyte and a non-loaded region which is not loaded with a solid electrolyte. The non-loaded region has a non-communication region in which both sides of the porous body in the stacking direction are not in communication with each other. The non-communication region is provided in a position where the non-communication region is continued to the outer peripheral part of the electrolyte region and surrounds the electrolyte region.
Claims8
A secondary battery comprising:
- a porous body having an electrolyte region on which a solid electrolyte is supported and a non-supporting region on which the solid electrolyte is not supported;
- and
- a positive electrode and a negative electrode disposed above and below the porous body so as to sandwich the electrolyte region, wherein
- the non-supporting region has a non-communicating region in which both sides of the porous body in a lamination direction do not communicate with each other,
- the non-communicating region is continuous with an outer peripheral portion of the electrolyte region and is provided at a position surrounding the electrolyte region, and an outer shape of the electrolyte region is located outside outer shapes of the positive electrode and the negative electrode when viewed along the lamination direction.
