The following are 4 common energy storage battery shell materials and their characteristics: (1) Aluminum alloy It has good electromagnetic shielding performance, which can protect the battery from electromagnetic interference.
It must have good deep drawing performance, and the mechanical properties must be stable. within the requirements. 2) In order to effectively protect the internal battery structure, under the premise of ensuring the necessary plasticity, the power battery shell must also have sufficient strength and hardness. 3) In order to adapt to different use environments and ensure the
New battery materials must simultaneously fulfil several criteria: long lifespan, low cost, long autonomy, very good safety performance, and high power and energy density. Another important criterion when selecting new materials is their environmental impact and sustainability. To minimize the environmental impact, the material should be easy to recycle and re-use, and be

In this review, we focus on core-shell materials for applications in advanced batteries such as LIBs, LSBs and SIBs.
Steel is the most economical and sustainable battery housing material for mass production. How does the battery housing protect? & What conditions must the battery case meet?
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. •
Models such as Geely Emgrand EV450 and GAC Trumpchi GE3 530 are packaged with SMC lightweight materials for the upper shell and high-strength aluminum for the lower shell. The energy density of the latter battery system is 160Wh/kg, which is already at the mainstream level.

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.
Glass fibre top covers, bottom covers and impact protection plates can provide a more cost-effective material for battery cases. The most challenging factor is TRP, as the combustion needs to be contained in the box. Then there are EMI, thermal and electrical isolation and mechanical issues of drive loads, crashes and impacts to consider.

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.
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).
