ELECTROCHEMICAL DEVICE
Document Type and Number:
Japanese Patent JP2015162294
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electrochemical device which is high in heat dissipation property.SOLUTION: An electrochemical device according to an embodiment of the present invention comprises: a case; a power storage device; a first terminal; a second terminal; and a heat dissipation part. The case has a case main body and a metal lid. The case main body includes: a bottom face; a circumferential face formed to connect to the bottom face; and a first inner face. The lid is joined with the case main body and includes a second inner face opposed to the first inner face; a liquid room is formed between the case main body and the lid. The power storage device has an electrolytic solution, a first electrode part disposed on the first inner face, and a second electrode part connected to the second inner face, and it is housed in the liquid room. The first terminal is formed on the bottom face, and connected with the first electrode part. The heat dissipation part has: a first metal line formed inside the case main body to extend from the lid toward the bottom face; and an exposed part connected to the first metal line and the second terminal and formed in the circumferential face.
