“…With regards to the total weight, it is indispensable to look for new current substrates with lower densities [32]. In a later publication [33], the processability of embedded solid-state thin-film lithium-ion batteries was investigated to optimize the curing cycle with respect to the battery capacity retention.…”

Multifunctionalization of fiber-reinforced composites, especially by adding energy storage capabilities, is a promising approach to realize lightweight structural energy storages for future transport vehicles. Compared to conventional energy storage systems, energy density can be increased by reducing parasitic masses of non-energy-storing components and by benefitting from the composite meso-and microarchitectures. In this paper, the most relevant existing approaches towards multifunctional energy storages are reviewed and subdivided into five groups by distinguishing their degree of integration and their scale of multifunctionalization. By introducing a modified range equation for battery-powered electric aircrafts, possible range extensions enabled by multifunctionalization are estimated. Furthermore, general and aerospace specific potentials of multifunctional energy storages are discussed. Representing an intermediate degree of structural integration, experimental results for a multifunctional energy-storing glass fiber-reinforced composite based on the ceramic electrolyte Li 1.4 Al 0.4 Ti 1.6 (PO 4 ) 3 are presented. Cyclic voltammetry tests are used to characterize the double-layer behavior combined with galvanostatic charge-discharge measurements for capacitance calculation. The capacitance is observed to be unchanged after 1500 charge-discharge cycles revealing a promising potential for future applications. Furthermore, the mechanical properties are assessed by means of four-point bending and tensile tests. Additionally, the influence of mechanical loads on the electrical properties is also investigated, demonstrating the storage stability of the composites.

“…Some common approaches are to incorporate commercial, prismatic, lithium-ion battery cells into structural components 7,10,11 or to reinforce solid-state lithium cells with high-strength backing (usually carbon fiber reinforced plastic, or CFRP). 4,12,13 A more integrated, multifunctional approach is to use the same material composite for both energy storage and structural support. This type of design was first described by Snyder et al, who proposed and fabricated a layered system consisting of a metal mesh coated with a lithium-based cathode material, a fiberglass separator, a carbon fiber anode, and a solid polymer electrolyte binding the components.…”

Carbon fiber electrodes for structural supercapacitors were modified to achieve increases in specific capacitance and energy density. In cyclic voltammetry tests with a liquid electrolyte, the specific capacitance of a commercial carbon fiber fabric weave was 0.84 F g −1 or lower, depending on the sweep rate. Impregnation of the carbon fiber with multiwall carbon nanotubes (MWCNT) or electrochemical functionalization of the carbon fiber increased the capacitance to 3 F g −1 . Electrochemical functionalization of the MWCNT-impregnated carbon fiber further increased the capacitance to 7.2 F g −1 . Electrochemical synthesis and deposition of polyaniline on carbon fiber electrodes increased the electrode capacitance to 26 F g −1 . MWCNT and polyaniline were incorporated into structural supercapacitors made of carbon fiber electrodes, glass fiber separator, and poly(ethylene glycol)-based solid polymer electrolyte. Incorporation of MWCNT increased the specific capacitance and energy density 28-fold, to 125 mF g −1 and 17.4 mWh kg −1 , respectively. Mechanical properties were comparable to previously demonstrated structural energy storage devices. Although the specific capacitance of these solid-state supercapacitors was significantly higher than what was previously demonstrated, the energy density, rate capability, and mechanical performance still require significant improvements for multifunctional structural energy storage devices to be competitive with conventional supercapacitors and carbon fiber composites. In multifunctional material systems, two or more functions are performed by the same material, component, or structural unit.1 The goal in the design of such systems is a smaller volume or mass compared to a combination of corresponding monofunctional elements. One of the most common types of multifunctional material systems is structural energy storage, in which a battery, capacitor, or supercapacitor acts as a structural element for the overall system. Various forms of structural energy storage have been described, 2 and these systems have been proposed for application in communications satellites, 3 spacecraft, 4 ground vehicles, 5 and unmanned aerial vehicles (UAV). 6-9Small UAVs are typically powered by rechargeable batteries and are prime candidates for incorporation of a structural battery, for example as part of a wing or fuselage. Incorporation of structural energy storage can theoretically increase the flight endurance time in small UAVs because of the interdependence of the subsystem weights, amount of available energy, and flight endurance. 7,9 Theoretical analysis by our own group predicted as much as 200% increase in flight endurance when structural batteries are fully incorporated into a small UAV. 9Even modest increases in flight time, such as 10% or 20%, would provide significant benefit because missions are often limited to less than an hour endurance.Much of the previous work on structural energy storage has focused on lithium-ion batteries. Some common approaches are to incorporate commerc...

“…The multifunctional structural battery concept became an area of research interest almost two decades ago, with limited initial success [19][20][21][22]. However, researchers have since had further opportunities for advanced development of structurally integrated batteries (and capacitors and supercapacitors) following recent developments in tangentially-related technology fields, including material synthesis, characterization techniques, and computational modeling [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. The first group of efforts represented a holistic, top-down approach that aimed for shape, packaging, and load path optimization of off-the-shelf batteries.…”

“…The first group of efforts represented a holistic, top-down approach that aimed for shape, packaging, and load path optimization of off-the-shelf batteries. Approaches ranged from optimization of the directional arrangements of batteries to enhance their structural stability [22,30,41] to encasement of pre-packaged batteries in lightweight structural materials [19,25,26,31,32,42,43], and ingenious load path redirection techniques for improved crash absorption [35,44]. At a more fundamental material level, the second bottom-up approach aimed to modify the compositions or structures of the battery materials to enhance their mechanical robustness.…”

This work proposes and analyzes a structurally-integrated lithium-ion battery concept. The multifunctional energy storage composite (MESC) structures developed here encapsulate lithium-ion battery materials inside high-strength carbon-fiber composites and use interlocking polymer rivets to stabilize the electrode layer stack mechanically. These rivets enable load transfer between battery layers, allowing them to store electrical energy while also contributing to the structural load carrying performance, without any modifications to the battery chemistry. The design rationale, fabrication processes, and experimental mechano-electrical characterization of first-generation MESCs are discussed. Experimental results indicate that the MESCs offer electrochemical performance comparable to standard lithium-ion cells, despite the disruptive design change. The mechanical performance of MESCs is assessed via quasi-static three-point bending tests, with results showing significantly improved mechanical stiffness
