ELECTRIC DOUBLE LAYER DEVICE

摘要

The present invention relates to an electric double layer device. The electric double layer device comprises a urethane potting part (50) which is filled in a gap between a through hole and a first terminal (21) exposed to the outside of a rubber closure (40), and a gap between a second terminal (22) and a second through hole (42). An aluminum oxide layer (A1) is formed by anodizing the aluminum terminal (A) of the second terminal (22) and the first terminal (21). Thereby, lifespan can be relatively increased.
