Core-shell structures allow optimization of battery performance by adjusting the composition and ratio of the core and shell to enhance stability, energy density and energy storage capacity.
Structural battery composites (SBCs) represent an emerging multifunctional technology in which materials functionalized with energy storage capabilities are used to build load-bearing structural components.
Composite carbon fiber materials offer excellent impact resistance, providing an additional layer of protection for the battery pack against external shocks and collisions. This characteristic enhances the safety of the battery box structure and minimizes the risk of damage to the battery cells.
If the battery enclosure is made of polymer composites, there is a possibility of decomposition and loss of its primary functions as a structure and cover. The risk of catastrophic damage increases if the fire breaches the battery enclosure and directly affects the battery cells, resulting in thermal runaway from external abuse.
However, this method requires accurate datasets obtained from experimental results. Nevertheless, the challenge in developing polymer composites for battery packs lies in ensuring that the representation of material characterization, namely flame retardancy, thermal performance, and mechanical properties, can reflect real-world conditions.
Battery systems with core–shell structures have attracted great interest due to their unique structure. Core-shell structures allow optimization of battery performance by adjusting the composition and ratio of the core and shell to enhance stability, energy density and energy storage capacity.
In a total cost analysis, battery cases made of composite material can even achieve a cost level similar to aluminum and steel in the future due to the many advantages. In addition, our materials meet other requirements for battery housings, such as electromagnetic compatibility (EMC), water and gas tightness.
