6 FAQs about [Battery cell shell breaking technology]

What is the material phase of battery 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).

What is the role of battery shell in a lithium ion battery?

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.

Why is a carbon shell a good choice for a battery?

At the same time, the carbon shell exhibits good conductivity, facilitating the transmission and diffusion electrons and lithium ions, therefore enhancing the electrochemical performance of the battery.

Does nickel plated steel make a good battery shell?

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.
