Zinkelektrode für alkalische Speicherbatterie

摘要

A negative zinc electrode for an alkaline storage battery capable of suppressing the occurrence of dendrite and shape change is provided. The negative zinc electrode comprises an electrode using zinc as an active material and a polymer layer formed substantially in direct contact with the electrode, the polymer layer comprising a polymer having an oxygen permeability constant of not less than 1 x 10<-><1><0> cm<3> (STP) cm<-><1>s<-><1>cmHg<-><1>. Examples of such polymer include a polymer selected from the group consisting of polydimethylsiloxanes, polyorganosiloxanes, polyvinyltriorganosiloxanes, polyalkylsulfones, poly(4-methylpentene-1), poly(2,6-dimethylphenylene oxide) and low-density polyethylene, or is said polymer with at least one functional group introduced therein.
