Current state-of-the-art structural battery composites are made from carbon fibers. [5, 9] The composite has a laminated architecture, very similar to traditional composites and conventional Li-ion batteries. The idea is for every material constituent to play, at least, dual roles in the composite material.
Structural battery composites are one type of such a multifunctional material with potential to offer massless energy storage for electric vehicles and aircraft. Although such materials have been demonstrated, their performance level and consistency must be improved. Also, the cell dimensions need to be increased.
This corresponds to a doubling of the multifunctional performance of the structural battery composite compared with that of the first-generation structural battery. This improvement has been achieved solely by employing a repeatable manufacturing scheme, using resin infusion resembling that used for conventional composites.
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 lithium-oxygen batteries, core–shell materials can improve oxygen and lithium-ion diffusion, resulting in superior energy density and long cycle life . Thus, embedding core–shell materials into battery is a highly effective approach to significantly enhance battery performance , , .
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.
