Abstract

The battery of the present disclosure comprises a plurality of electrode bodies, wherein one of the electrode bodies and another of the electrode bodies are connected via a conductive material, each of the electrode bodies includes a metal current collector, an active material layer, and an electrolyte layer, the metal current collector has a connection surface which contacts the conductive material and a laminate surface which contacts the active material layer, and a ten-point average roughness of the laminate surface is less than a ten-point average roughness of the connection surface. According to the battery of the present disclosure, both adhesion between the metal current collector and the active material layer in the electrode body and connectivity between the electrode bodies via the conductive material can be achieved.
