(EN) SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE
(JA) 二次電池
Abstract
(EN)
This secondary battery is provided with: an electrode body which is provided with a positive electrode plate and a negative electrode plate; a battery case which contains the electrode body, while having an opening; a sealing body which seals the opening; an internal terminal which is provided inside the sealing body and is connected to the positive electrode plate or the negative electrode plate; and an external terminal which is provided outside the sealing body and is connected to the internal terminal. The external terminal has a rivet which is formed so as to penetrate through the sealing body; the internal terminal comprises a first portion that is formed of a first metal and a second portion that is formed of a second metal; and the external terminal is formed of a second metal, while being bonded to the second portion of the internal terminal at the rivet.
