Abstract

PURPOSE:To sharply decrease generation amount of hydrogen gas without deteriorating discharge performance by constituting a negative electrode active material out of mercurized zinc alloy in expand-shape and making it include, as an alloy element, one kind or more selected among lead, indium, cadmium, thallium and gallium and one kind or more selected among aluminum, alkali metal and alkali earth metal. CONSTITUTION:In a negative electrode active material consisting of zinc, the form is expand-shape and it includes, as an alloy element, one kind or more selected among indium, zinc cadmiun, thallium and gallium, and one kind or more selected among aluminum, alkali metal and alkali earth metal. Hereupon, the content rate of one kind or more selected among indium, lead, cadmium, thallium and gallium inside the zinc alloy is determined as 0.001-1.0% by weight. And the content rate of one kind or more selected among aluminum, alkali metal and alkali earth metal is determined as 0.001-0.2% by weight.
