BATTERY JAR FOR NONAQUEOUS SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a battery jar for a nonaqueous secondary battery, which also functions as a counterweight when it is used for a power source for a forklift.SOLUTION: A battery jar is formed from austenitic cast iron organized by a matrix made of an Fe alloy in which an austenite phase serves as a main phase in an ordinary temperature range. The austenitic cast iron is excellent in resistance to corrosion caused by an electrolyte of a nonaqueous secondary battery and greater in specific gravity than an aluminium alloy and the like.
