Nickel plating technology for lithium battery steel shell

Does nickel plating improve corrosion resistance?

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). Nickel plating can be achieved through barrel plating, pre-plating and pre-plating plus barrel plating (Fig. S5b–d).

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.

How ni-coated steel sheets can improve the safety of Li-ion batteries?

a battery ca e with high Ni coverage can improve the safety of Li-ion batteries.1. IntroductionNi-coated steel sheets have been used for cases of various types of batteries containing concentrated alkaline electrolyte solutions, such as alkaline manganese batteries, Ni-Cd batteries, and Ni-MH batter

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.

Does nickel plated cold rolled steel affect battery safety?

Interestingly, if the dynamic effect of nickel-plated cold-rolled steel is not considered in the model, a late short-circuit triggering time will be expected thus leading to the underestimation of the battery safety upon mechanical abusive loading (Table 2).
