Considering the fact that LIB is prone to be short-circuited, shell material with lower strength is recommend to select such as material #1 and #2. It is indicated that the high strength materials are not suitable for all batteries, and the selection of the shell material should be matched with the safety of the battery. Table 3.
Aluminum and low-alloy steels are the traditional choice for battery housings. But these materials can be restrictive in terms of both design and manufacturing flexibility and have limited safety potential.
