“…For example, the coextruded LiFePO 4 and CF with a solid polymer electrolyte in a micro‐battery showcases an elevated modulus of 124 GPa and a tensile strength of 1.1 GPa. This configuration yields an energy density of 77 Wh kg −1 at a current density of 0.5 C, holding promise for electric devices reliant on structural battery designs 90 . Notably, its tensile strength rivals that of commercial fiber‐reinforced polymer composites (CFRP: axial modulus: 155–400 GPa, axial tensile strength: 1.29–2.8 GPa) used for structural applications 92 .…”

Structural batteries have emerged as a promising alternative to address the limitations inherent in conventional battery technologies. They offer the potential to integrate energy storage functionalities into stationary constructions as well as mobile vehicles/planes. The development of multifunctional composites presents an effective avenue to realize the structural plus concept, thereby mitigating inert weight while enhancing energy storage performance beyond the material level, extending to cell‐ and system‐level attributes. Specifically, multifunctional composites within structural batteries can serve the dual roles of functional composite electrodes for charge storage and structural composites for mechanical load‐bearing. However, the implementation of these multifunctional composites faces a notable challenge in simultaneously realizing mechanical properties and energy storage performance due to the unstable interfaces. In this review, we first introduce recent research developments pertaining to electrodes, electrolytes, separators, and interface engineering, all tailored to structure plus composites for structure batteries. Then, we summarize the mechanical and electrochemical characterizations in this context. We also discuss the reinforced multifunctional composites for different structures and battery configurations and conclude with a perspective on future opportunities. The knowledge synthesized in this review contributes to the realization of efficient and durable energy storage systems seamlessly integrated into structural components.

To stabilize the Earth’s climate, large-scale transition is needed to non-carbon-emitting renewable energy technologies like wind and solar energy. Although these renewable energy sources are now lower-cost than fossil fuels, their inherent intermittency makes them unable to supply a constant load without storage. To address these challenges, rechargeable electric batteries are currently the most promising option; however, their high capital costs limit current deployment velocities. To both reduce the cost as well as improve performance, 3D printing technology has emerged as a promising solution. This literature review provides state-of-the-art enhancements of battery properties with 3D printing, including efficiency, mechanical stability, energy and power density, customizability and sizing, production process efficiency, material conservation, and environmental sustainability as well as the progress in solid-state batteries. The principles, advantages, limitations, and recent advancements associated with the most common types of 3D printing are reviewed focusing on their contributions to the battery field. 3D printing battery components as well as full batteries offer design flexibility, geometric freedom, and material flexibility, reduce pack weight, minimize material waste, increase the range of applications, and have the potential to reduce costs. As 3D printing technologies become more accessible, the prospect of cost-effective production for customized batteries is extremely promising.
