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.
Additional safety components, such as a positive thermal coefficient barrier layer , current interruption device, thermal fuses, and vents , and enclosure of battery packs are utilized to ensure battery safety, which introduces extra weight, volume and cost to the batteries.
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.
Hence, to develop structural batteries, strategies for mechanical reinforcement are required. They can be divided into two main categories: (1) cell-level designs, where the reinforcement does not play a major role in energy storage (Fig. 2 (a)), and (2) material-level designs, where multifunctional materials are used for both energy
A term “structure-battery” materials has been applied to such designs , . This approach targets elimination of inert mass of the battery enclosure by placing the battery cells within the structural components with no, or minimal, modification done to the cells.
Safety is one of the top requirements for all batteries and it is even more critical for structural batteries since their working environment is mechanically much harsher. Therefore, safety requirements on structural batteries should be more strict than conventional batteries.
