Effect of Lanthanide Additives to a Nickel Oxide Electrode of a Sealed Nickel-Zinc Battery on the Self-Discharge and Hydrogen Pressure

摘要

The influence exerted by addition of a nickel-based alloy containing lanthanides (La,Ce,Nd,Pr) to the active paste of a nickel oxide electrode on the self-discharge and hydrogen pressure in a sealed nickel-zinc battery was studied.Proceeding with studies of gas evolution and gas absorption in a sealed nickel-zinc (SNiZn) battery with a nickel oxide electrode (NOE) made of spherical nickel hydroxide [1],we examined the influence exerted by addition of a nickel-based alloy containing lanthanides (La,Ce,Nd,Pr) to the active paste of a nickel-oxide electrode on the self-discharge and hydrogen pressure in an SNiZn battery.
