Module structure and optimization descriptions The module structure surrounding battery cells should be optimized to maximize cell volume or weight while satisfying mechanical and thermal safety constraints. This section presents the basic module structure used in this study and summarizes the optimization process.
Conclusions This study proposes an optimization framework for a battery module structure that maximizes the energy density while satisfying both the mechanical and thermal constraints of pouch cell LIBs. To this end, mechanical and thermal models of module structures have been developed.
To achieve the required battery pack voltage, several battery modules are connected in series to a battery string [ 7] (pp. 31–32). To increase capacity, serial strings of battery modules can be connected in parallel to form a larger battery pack [ 8] (p. 300).
Individual cells are too small to power large devices, while entire battery packs are cumbersome to handle and maintain. Modules, however, strike the right balance, making it easier to design, assemble, and maintain complex energy storage systems. Part 2. Battery module composition
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 mechanical performance of a composite is influenced by the design and properties of its components. For structural batteries, the rigidity under bending is an important engineering criterion, which depends on whether the reinforcing components are placed inside or outside the battery.
