<p>PROBLEM TO BE SOLVED: To provide a power-storage device which enables the increase in the efficiency at which an electrolyte in a storage container is used in a battery reaction.SOLUTION: A nonaqueous electrolyte secondary battery 1 comprises: an electrode body 11 including current collecting parts of positive and negative electrodes; an electrolyte; a storage container constituted by a container body 10 and a lid part 20 for storing the electrode body 11 and the electrolyte; and a spacer 15 disposed between an inner wall of the storage container and as at least one of the current collecting parts of the positive and negative electrodes of the electrode body 11, a negative electrode-side metal foil exposed part 11b. The spacer 15 has electrolyte paths which allow the electrolyte to pass therethrough.</p> |
