What are the structural components of electric vehicle battery packs?

In the electric vehicle battery pack described above, the mechanical load-bearing functionality is entirely carried by structural components other than the battery packs. For instance, structural components refer to the module casings and upper and lower battery pack covers.

How to achieve high-performance rigid structural batteries using single-function materials?

Therefore, to achieve high-performance rigid structural batteries using single-function materials, it is necessary to address bottlenecks in key materials, packaging processes, battery design, and other aspects. 4.2. Constructing rigid structural batteries using multifunctional materials

What are structural batteries?

This type of batteries is commonly referred to as “structural batteries”. Two general methods have been explored to develop structural batteries: (1) integrating batteries with light and strong external reinforcements, and (2) introducing multifunctional materials as battery components to make energy storage devices themselves structurally robust.

Can multifunctional materials be used to build rigid structural batteries?

Looking toward long-term development, achieving mechanical/electrochemical decoupling at the material or even atomic scale, i.e., utilizing multifunctional materials to build rigid structural batteries, holds the potential for groundbreaking performance enhancements. 4.1. Constructing rigid structural batteries using single-function materials

Is mechanical/electrochemical decoupling possible for rigid structural batteries?

However, based on the current development and application of rigid structural batteries, achieving mechanical/electrochemical decoupling at the component and battery scales, i.e., employing single-function materials to construct rigid structural batteries, appears more practical.

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.
