ALKALINE STORAGE BATTERY

摘要

PURPOSE:To prevent the electrolytic corrosion generated in gastric juice even when accidentally swallowed by making a battery container that is used additionally as a positive electrode terminal with steel provided with high chrome content. CONSTITUTION:A battery container that is used additionally as a positive electrode terminal is made of steel containing chrome of 16wt% or more that hardly contains nickel or made of high chrome stainless steel containing chrome of 24- 26wt% and nickel of 18- 22wt%, respectively. Since chrome elutes first because of a difference in the trend of metal exhibiting the property of electric cathode and the electrochemical equivalent value of chrome is small and a great amount of battery electric capacity is consumed for elution thereof the battery is consumd before a hole is perforated in the container and can prevent the container from being perforated.
