Composite structural batteries with Co3O4/CNT modified carbon fibers as anode: Computational insights on the interfacial behavior

Designing Structural Electrochemical Energy Storage Systems: A Perspective on the Role of Device Chemistry

“…However, no mechanical studies were performed; since the electrochemical testing was performed with a conventional, rather than multifunctional electrolyte, their suitability for SESDs is not yet clear. Computational studies have proposed Co 3 O 4 as structural anode ( Hu et al, 2021 ); experimental testing is yet to be performed. Most of high-capacity anode materials, including Co 3 O 4 and silicon, exhibit low cycling stability, due to volume expansion during Li insertion/extraction.…”

Low-Temperature Structural Battery Electrolytes Produced by Polymerization-Induced Phase Separation

“…9 Carbon nanotube (CNT) composites and carbon fabrics have also been used to create structural electrodes. 10,11 In our past work, we have explored reduced graphene oxide nanosheets and branched aramid nanofibers (BANFs) as structural reinforcements in structural battery electrodes to provide a 2-fold improvement in Young's modulus and tensile strength over commercial battery electrodes. 4 By comparison, structural battery electrolytes (SBEs) have not received as much attention as structural electrodes.…”

“…Previous work on structural batteries has utilized carbon fiber (CF) composites as mechanical reinforcements to form structural electrodes, for which CFs can act as anodes for lithium-ion (Li + ) intercalation or as conducting skeletons that support an active cathode material .

Carbon fiber reinforced structural Zn-ion battery composites with enhanced mechanical properties and energy storage performance

“…1a), which can achieve the multifunctional performance of electrochemical energy storage and withstand mechanical loading, attracting more and more attention. [2][3][4][5] Although several research groups have carried out many inventive studies on structural batteries, 6,7 previously reported studies are typically focused on unsafe structural lithium-ion batteries [8][9][10][11] with a composite electrode, fabricated by the following process: the slurry of the active material is coated on carbon ber fabric and dried. Although residual stress will not exist, due to the poor binding force originating from the polymer binder, such as poly(vinylidene uoride), between the solid-solid interface of active materials and the current collector, the powder active materials cannot maintain their integrity and usually fall off from the carbon ber under external load, 12,13 vividly depicted in Fig.…”
