“…Consequently, the shear load case more closely approached to the general rule of mixtures, and therefore, showed a sharp variation in stiffness change. This is in line with the results of previous studies [29,53] where shear results more closely followed the rule of mixtures.…”

“…For example, simple gel PEs exhibit good ionic conductivity (∼10 −3 S/cm at room temperature), but low mechanical strength (∼10 MPa)) [20] . A variety of strategies have been explored to improve this balance, including the use of nanocomposite polymer electrolytes [21][22][23] , interpenetrating polymer networks [24,25] , block-copolymer architectures [24,26] , and bicontinuous aerogels [27][28][29] .…”

“…More ordered, truss-like lattice structures and triply periodic minimal surfaces (TPMSs), such as the body-centered cubic lattice (BCC) and the Schwarz's primitive (Schwarz-P) minimal surface, have been recently studied as attractive potential microstructures for SEs [29,[34][35][36] . The Schwarz-P is often assumed to be an ideal solution for multi-cell structures due to its simple three-axis symmetric pipe-network architecture.…”

Multifunctional structural materials offer compelling opportunities to realize highly efficient products. However, the need to fulfil disparate functions generates intrinsically conflicting physical property demands. One attractive strategy is to form a bi-continuous architecture of two disparate phases, each addressing a distinct physical property. For example, structural polymer electrolytes combine rigid and ion-conducting phases to deliver the required mechanical and electrochemical performance. Here, we present a general methodology, based on topology optimization, to identify optimal microstructures for particular design considerations. The numerical predictions have been successfully validated by experiments using 3D printed specimens. These architectures are directly relevant to multifunctional structural composites whilst the methodology can easily be extended to identify optimal microstructural designs for other multifunctional material embodiments.

“…The concept of phase separation introduced by Gienger et al [ 83 ] was recently reinterpreted by Beringer et al [ 91 ] and Lee and coworkers [ 26 ], who designed and 3D-printed optimized polymeric microstructures with enhanced multifunctional performance. Based on the know-how developed during prior studies, Beringer et al [ 91 ] investigated the definition of an engineered structural electrolyte solution in which the involved phases were distinctly segregated to reduce at the minimum the risk to compromise their properties, and the microstructure was geometrically optimized to maximize the properties of interest in the multi-phase system. This philosophy led the group to use additive manufacturing techniques to produce epoxy-based Maxwell trusses with high structural efficiency to host liquid electrolytes (see Figure 24 a).…”

Structural power composites stand out as a possible solution to the demands of the modern transportation system of more efficient and eco-friendly vehicles. Recent studies demonstrated the possibility to realize these components endowing high-performance composites with electrochemical properties. The aim of this paper is to present a systematic review of the recent developments on this more and more sensitive topic. Two main technologies will be covered here: (1) the integration of commercially available lithium-ion batteries in composite structures, and (2) the fabrication of carbon fiber-based multifunctional materials. The latter will be deeply analyzed, describing how the fibers and the polymeric matrices can be synergistically combined with ionic salts and cathodic materials to manufacture monolithic structural batteries. The main challenges faced by these emerging research fields are also addressed. Among them, the maximum allowable curing cycle for the embedded configuration and the realization that highly conductive structural electrolytes for the monolithic solution are noteworthy. This work also shows an overview of the multiphysics material models developed for these studies and provides a clue for a possible alternative configuration based on solid-state electrolytes.

Integration of lithium‐ion batteries into fiber‐polymer composite structures so as to simultaneously carry mechanical loads and store electrical energy offer great potential to reduce the overall system weight. Herein, recent progresses in integration methods for achieving high mechanical efficiencies of embedding commercial lithium‐ion batteries inside composite materials are reviewed. The manufacturing techniques used to fabricate energy storage structural composites are discussed together with a comparison of their mechanical properties, energy storage capacity, and electrical performance. The mechanical performance of energy storage composites containing lithium‐ion batteries depends on many factors, including manufacturing method, materials used, structural design, and bonding between the structure and the integrated batteries. Energy storage composites with integrated lithium‐ion pouch batteries generally achieve a superior balance between mechanical performance and energy density compared to other commercial battery systems. Potential applications are presented for energy storage composites containing integrated lithium‐ion batteries including automotive, aircraft, spacecraft, marine and sports equipment. Opportunities and challenges in fabrication methods, mechanical characterizations, trade‐offs in engineering design, safety, and battery subcomponents are also discussed.
