Abstract: A laminate-type power storage element includes a flat plate-shaped electrode body and an exterior body. The electrode body is configured by stacking a sheet-shaped positive electrode and a sheet-shaped negative electrode on either side of a separator. The exterior body is formed in a flattened bag-shape by thermocompression bonding peripheral edge regions of two opposing laminated films, to seal the electrode body inside the flattened bag-shape of the exterior body together with an electrolyte. The separator has a sheet-shaped substrate and at least one bonding layer formed on at least one surface of the substrate. A peripheral edge portion of the separator is sandwiched between and bonded by the two laminated films at a peripheral inside of the peripheral edge regions of the two laminated films.

Abstract: A negative electrode contains at least composite particles. The composite particles each contain a negative electrode active material particle and a coating. The coating is formed on a surface of the negative electrode active material particle. The coating contains at least a metal organic framework. The metal organic framework is formed by alternately stacking a first layer and a second layer. The first layer is formed by stacking an aromatic compound in a direction intersecting with a direction of stack of the first layer and the second layer. The aromatic compound contains two carboxylate anions. The two carboxylate anions satisfy para-positional relation. The second layer is formed of lithium ions coordinated to the carboxylate anion.
