The steel material for this battery is physically stable with its stress resistance higher than aluminum shell material. It is mostly used as the shell material of cylindrical lithium batteries. Structure of Steel Sheel Battery
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.
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).
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.
The choice of nickel plated steel on its strength is critical. This study provides a solid dynamic constitutive modeling methodology for the LIB shell and the strain rate sensitive which may stimulate further study towards the safety design and evaluation of battery cells and packs.
It is mainly used in square lithium batteries. They are environmentally friendly and lighter than steel shell batteries while having strong plasticity and stable chemical properties. Generally, the material of the aluminum shell is aluminum-manganese alloy, and its main alloy components are Mn, Cu, Mg, Si, and Fe.
