Customer ServiceConsidering 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.
Among all cell components, the battery shell plays a key role to provide the mechanical integrity of the lithium-ion battery upon external mechanical loading. In the present study, target battery shells are extracted from commercially available 18,650 NCA (Nickel Cobalt Aluminum Oxide)/graphite cells.
XRD pattern illustrates that the material phase of the battery shell is mainly Fe, Ni and Fe-Ni alloy (Fig. 1 e). The surface of the steel shell has been coated with a thin layer of nickel (Ni) to improve the corrosion resistance, which is also demonstrated by cross-sectional image observation (Fig. S5a).

However, the commercialization of Li metal batteries faces challenges, primarily attributed to uncontrolled growth of Li dendrites, which raises safety concerns and lowers coulombic efficiency.
Conclusions LIB shell serves as the protective layer to sustain the external mechanical loading and provide an intact electrochemical reaction environment for battery charging/discharging. Our rationale was to identify the significant role of the dynamic mechanical property of battery shell material for the battery safety.
Traditionally, high strength is the priority concern to select battery shell material; however, it is discovered that short-circuit is easier to trigger covered by shell with higher strength. Thus, for battery safety reason, it is not always wise to choose high strength material as shell.
