“…Furthermore, almost all of these demonstrate poor multifunctional performance, where either the electrical or the mechanical performance is prioritized. For example, Thakur and Dong [ 27 ] reported an energy density of 24 Wh kg −1 at an elastic modulus of only 0.29 GPa, whereas Meng et al [ 28 ] demonstrated a structural battery material with an elastic modulus of 7.0 GPa but a low energy‐storage capability of 1.4 Wh kg −1 . Moyer et al reported a multifunctional device, exploiting CFs as collectors.…”

Engineering materials that can store electrical energy in structural load paths can revolutionize lightweight design across transport modes. Stiff and strong batteries that use solid‐state electrolytes and resilient electrodes and separators are generally lacking. Herein, a structural battery composite with unprecedented multifunctional performance is demonstrated, featuring an energy density of 24 Wh kg−1 and an elastic modulus of 25 GPa and tensile strength exceeding 300 MPa. The structural battery is made from multifunctional constituents, where reinforcing carbon fibers (CFs) act as electrode and current collector. A structural electrolyte is used for load transfer and ion transport and a glass fiber fabric separates the CF electrode from an aluminum foil‐supported lithium–iron–phosphate positive electrode. Equipped with these materials, lighter electrical cars, aircraft, and consumer goods can be pursued.

“…Structural energy and power is an emerging field that combines the mechanical properties of structural composites with the energy-storage properties of batteries and supercapacitors. 1,2 Recent interest in structural energy and power is driven by the potential for reduced mass and volume, which promises lighter vehicles and aircraft, more miles between recharging, and enhanced safety. 3,4 However, battery and supercapacitor electrodes do not possess good mechanical properties as they are often formed from brittle materials; 5 this leads to unacceptably low values in the multifunctional efficiency parameter (<1), which is the performance metric used to describe the combined mechanical and energy-storage properties.…”

Traditional battery and supercapacitor electrodes suffer from poor mechanical properties. Here, we harnessed non-covalent interactions between reduced graphene oxide (rGO) and branched aramid nanofibers to design strong supercapacitor electrodes. Dopamine functionalization and Ca 2+ ion addition led to tremendous improvements in mechanical performance while maintaining good energy-storage performance. The highest reported multifunctional efficiency parameter was realized for rGO-based electrodes. This work paves the way for highly multifunctional structural electrodes.

“…27 These values were comparable to those measured for carbon fiber based structural batteries fabricated by conventional lay-up processes. 8,23,66–69 Combined with the flexibility in preparing complex geometry composite parts, it well demonstrated the potentials of the proposed 3D printing technique in fabricating structural battery composites with carbon fibers. With each SPE-coated carbon fiber dispersed in the cathode doped matrix and working as a micro-battery cell, the corresponding dramatic intercalation surface area between electrolyte and active materials 6,45 can potentially help the 3D structural battery composite achieve higher energy density and specific capacities with further improvement of the 3D printing process.…”

Structural battery composites are capable of significant system level mass and volume reductions not possible with separate battery and structural components by simultaneously carrying mechanical loads and storing electrical energy. The ability to 3D print lithium-ion structural batteries in arbitrary geometries would not only allow a flexible battery design but also facilitate its implementation as a structural component. This study presents a new 3D carbon fiber structural battery composite 3D printed by an ultraviolet (UV)-assisted coextrusion deposition method. With individual carbon fibers coated by solid polymer electrolyte (SPE) and dispersed within cathode doped matrix, energy storage is achieved in micro-battery cells at the fiber level within the 3D printed structural battery composite. The 3D printed structural battery composites with various complex geometries are demonstrated by successfully powering up LEDs. The SPE coating and cathode doping effect on microstructure, printability, mechanical and electrochemical properties are further characterized and investigated. A trade-off between printability and electrochemical performance is observed due to hindered curing by the doped cathode materials. The obtained electrochemical and mechanical performance is comparable to the carbon fiber based structural battery composites fabricated by conventional lay-up processes. These well demonstrate the great potentials of the proposed 3D printing method in rapidly fabricating functional structural battery composite components with complex geometries.
