Abstract

An electric energy storage device in which a cell assembly having electrode leads is installed in a metal case. The electric energy storage device includes an internal terminal formed with a support, connection ribs and thorough portions, and the electrode leads include a part of electrode leads compressed by the support and the connection ribs of the internal terminal and a part of electrode leads located at the thorough portions of the internal terminal to maintain a shape thereof.

Claims7

Dependent claims

An electric energy storage device in which a cell assembly having electrode leads is installed in a metal case, the electric energy storage device comprising:

an internal terminal (120) formed with a support (121), connection ribs (122) and thorough portions (127) so that lower surfaces of the support (121) and the connection ribs (122) come into contact with a part of the electrode leads (110),
wherein the electrode leads (110) include a part of electrode leads compressed by the support (121) and the connection ribs (122) of the internal terminal (120) and another part of electrode leads located at the thorough portions (127) of the internal terminal (120) to maintain a shape thereof.

Dependencies are inferred from the claim text.
