Structural composite energy storage devices (SCESDs), that are able to simultaneously provide high mechanical stiffness/strength and enough energy storage capacity, are attractive for many structural and energy requirements of not only electric vehicles but also building materials and beyond .
Fabrication approaches to structural composite energy storage devices are as follows: (a) vacuum infusion and (b) wet lay-up. Sha et al. selected wet lay-up as the fabrication approach. The processing is very similar to vacuum infusion, both of which complete the curing of resin in vacuum.
The capabilities of SCESDs to function as both structural elements and energy storage units in a single engineering structure lead to reduction of volume/mass of the overall system. The designs of SCESDs can be largely divided into two categories.
The resulting multifunctional energy storage composite structure exhibited enhanced mechanical robustness and stabilized electrochemical performance. It retained 97%98% of its capacity after 1000 threepoint development of effective structural batteries. For instance, the bioinspired treeroot structure enhances (Figures 2D and 5E,F).
