The age-old steel versus aluminium debate continues in the world of battery enclosures, with suppliers of each claiming greater suitability than the other. Makers of steel promote its advantages in high strength and formability and repairability, and cost-effectiveness, with less carbon intensity in production than other materials.
carbon fiber plastic steel was higher than that of thin sheet metal [13]. The production output of thin sheet metal formed by stamping was higher than that of plastic steel made of fiber material. Its cost would be reduced in the process of batch manufacturing, and its manufacturing was more in line with the needs of the automobile industry.

Hot stamping is a useful technology to form low plasticity materials. During hot stamping, the blank is heated so as to increase the formability and decrease the flow resistance. If a multi-step hot stamping process is employed to form shell parts, the blank must be heated many times, due to the fast temperature drop in each stage.
