NEGATIVE ELECTRODE FOR NICKEL/ZINC SECONDARY BATTERY TO IMPROVE REACTION AREA AND FABRICATION METHOD THEREOF

摘要

A negative electrode for a nickel/zinc secondary battery and a fabrication method thereof are provided to improve the electrical characteristic of a secondary battery applying a negative plate by strengthening the binding power of the encapsulated negative active material and to prolong a cycle life by increasing the electric conduction area. A fabrication method of a negative electrode for a nickel/zinc secondary battery comprises (a) a step(S110) punching a plurality of penetration holes on a metal plate; (b) a step(S130) filling the encapsulated negative active material between two metal plates punched with the penetration hole; (c) a step(S140) forming a strip detaining the encapsulated negative active material between two metal plates by compressing the two metal plates with the encapsulated negative active material; (d) a step(S150) connecting at least two strips as the necessary capacity; (e) a step(S160) inserting at least two strips into the negative plate frame; and (s) a step(S170) adding the external force to at least two strips inserted into the negative plate frame and forming the concavo-convex.
