NEGATIVE ELECTRODE FOR NICKEL/ZINC SECONDARY BATTERY AND FABRICATION METHOD THEREOF

摘要

A fabrication method of a negative plate for a nickel/zinc secondary battery is provided to prevent the deintercalation of an electrode material caused by the expansion or shrinkage of an electrode according to the charging/discharging of a battery. A fabrication method of a negative plate for a nickel/zinc secondary battery comprises (a) a step(S110) punching a plurality of penetration holes in a metal plate; (b) a step(S130) filling a negative active material encapsulated between two metal plates; (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; and (e) a step(S160) inserting at least two strips into the negative plate frame.
