Sealed alkaline storage battery

摘要

The present invention provides a sealed alkaline storage battery comprising a container of polymer alloy mainly comprised of PPE and an olefin resin and containing PPE of 20-60 wt%, or a composite material of polymer alloy containing PPE and an inorganic powder of 5-50 wt%. Using this material as a container, it is possible to restrict decrease in an amount of electrolyte thereby providing a sealed alkaline storage battery having a long life, which is possible to guarantee a maintenance-free long life of 7-10 years.
