Negative electrode plate for nickel / hydrogen storage battery, method for producing the same, and nickel / hydrogen storage battery using the same

摘要

PROBLEM TO BE SOLVED: To provide a negative electrode plate for nickel and hydrogen storage battery that can prevent having a high internal pressure of the battery at overcharging and can form a nickel and hydrogen storage battery having an excellent large-current charge and discharge characteristic, and its manufacturing method, and a nickel and hydrogen storage battery using the same. SOLUTION: The negative electrode plate comprises a conductive support body 11, a layer 12 that contains a hydrogen storage alloy and is supported by the support body 11, nickel particles 13 arranged on the surface of the layer 12, and graphite particles 14 arranged between the nickel particles 13.
