Abstract:
An electricity storage device 20 includes a positive electrode 22, a negative electrode 23 containing a layered structure of an aromatic dicarboxylic acid metal salt as an electrode active material, and an ion conducting medium 27 capable of conducting carrier ions. The layered structure is formed by spray-drying a solution prepared by containing aromatic dicarboxylic acid anions and alkali metal cations by using a spray-drying apparatus.
