6 FAQs about [Development direction of battery lower shell]

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 Lib shell important for battery safety?

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.

How to implement structural batteries in vehicles?

To implement structural batteries in systems such as vehicles, several key points must be satisfied first, including mechanical and electrochemical performance, safety, and costs, as summarized in Fig. 8. In this section, these points will be briefly discussed, covering current challenges and future development directions. Figure 8.

Why are battery shells important?

Generally, battery shells serve as the protective layer for LIBs to withstand external mechanical loading and sustain the integrity of electrochemical functioning environment.

Should a battery be embedded in a sandwich design?

Multiple studies suggest that external reinforcement strategies – embedding the battery between structural layers in a sandwich design – tend to achieve higher specific energy and mechanical performance, since the two different components both keep their main functions.

Can a structural battery design increase driving range?

Their case study manifested that the driving range could be increased by 70% for lightweight vehicles with feasible structural battery designs. In addition, the performance analysis showed that separator thicknesses, electrolyte conductivities, and current collector designs are critical to the electrical performance.
