“…Another possible hybrid approach was proposed by Moyer and co-workers [ 24 , 25 ], who designed a composite plate with carbon-fiber-reinforced plastics (CFRP) face sheets encapsulating a carbon fiber-based Li-ion battery. The cell, in this case, was fabricated with doped graphite as anode and a cathode both soaked in an ionic liquid electrolyte with a commercial separator to avoid short circuits.…”

The transition to a sustainable society is paramount and requires the electrification of vehicles, the grid, industry, data banks, wearables, and IoT. Here, we show an all-solid-state structural battery where a Na+-based ferroelectric glass electrolyte is combined with metallic electrodes/current collectors (no traditional cathode present at fabrication) and thin-ply carbon-fiber laminates to obtain a coaxial multifunctional beam. This new concept aims to optimize the volume of any hollow beam-like structure by integrating an electrochemical system capable of both harvesting thermal and storing electrical energy while improving its mechanical performance. The coaxial cell is a coaxial cable where the dielectric is ferroelectric. The electrochemical results demonstrated the capability of performing three-minute charges to one-day discharges (70 cycles) and long-lasting discharges (>40 days at 1 mA) showing an energy density of 56.2 Wh.L−1 and specific energy of 38.0 Wh.kg−1, including the whole volume and weight of the structural cell. This is the highest specific energy among safe structural cells, while no Na+-based structural cells were found in the literature. The mechanical tests, instead, highlighted the coaxial cell capabilities to withstand severe inelastic deformation without compromising its functionalities, while increasing the flexural strength of the hosting structure. Moreover, the absence of alkali metals and liquid electrolytes together with its enhanced thermal properties makes this coaxial structural battery a valid and safe alternative as an energy reservoir for all the applications where traditional lithium-ion batteries are not suitable.

“…Moyer et al. [ 79,80 ] achieved this by integrating lithium‐ion battery materials into a CFRP laminate using the hand layup fabrication process shown in Figure . In this process, carbon fibers are used as the current collector for both the graphite anode and lithium iron phosphate cathode, which was coated with carbon nanotubes.…”

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.

“…The prototype of the battery was also integrated into a CubeSat structure to show how structural power composites could be used to provide an integrated power delivery system, saving weight and volume. In follow-up work, [ 63 ] Moyer and coworkers improved both the mechanical and electrochemical properties of the batteries via a polyacrylonitrile (PAN) coating of the electrodes (see Figure 18 b). The PAN coating, commonly used for improving the mechanical performance of carbon fibers in lightweight structures, was used to simply sandwich the active battery material to the carbon fibers for both the electrodes.…”

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.
