Failure Mode Analysis of Corrosion Phenomenon of Power Battery

As an important protective part of the battery of new energy electric vehicles, the corrosion resistance of the
battery box directly affects the durability and life of the battery, and even the safety of the whole vehicle.This paper will
start with several common failure modes in the corrosion of power battery box, and analyze the causes of them, so as to
provide a strong theoretical basis for the corrosion resistance design of battery box.
