Negative electrode plate for nickel-metal hydride storage battery, method for producing the same and nickel-metal hydride storage battery using the same

摘要

A negative electrode plate includes a conductive support and a first, a second and a third layer laminated on a surface of the support in this order from the support side. The first layer contains a hydrogen storage alloy powder and a first powder essentially made of a carbonaceous material. The second layer contains a hydrogen storage alloy powder, the first powder and a second powder having conductivity. The third layer contains the second powder as a main component.
