Stiff and strong batteries that use solid-state electrolytes and resilient electrodes and separators are generally lacking. Herein, a structural battery composite with unprecedented multifunctional performance is demonstrated, featuring an energy density of 24 Wh kg −1 and an elastic modulus of 25 GPa and tensile strength exceeding 300 MPa.
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.
The structural design of the battery significantly influences its flexibility. Variations in the structural designs of the batteries result in them experiencing different forces during deformation, including the location of the force and the direction and magnitude of the stress.
Utilizing structural batteries in an electric vehicle offers a significant advantage of enhancing energy storage performance at cell- or system-level. If the structural battery serves as the vehicle's structure, the overall weight of the system decreases, resulting in improved energy storage performance (Figure 1B).
All information indicates that structural batteries are promising solutions to enhance the performance of electrified transportation, and more transformative research and progress in material and device levels are needed to accelerate their implementation in the real world.
They are subjected to vibrations, stress, and other physical forces that can affect their performance and long-term stability. Ensuring the mechanical and electrochemical stability of structural batteries in such demands is thus crucial.
