The rational design of flexible electrodes is essential for achieving high performance in flexible and wearable energy-storage devices, which are highly desired with fast-growing demands for flexible electronics. Owing to the one-dimensional structure, nanowires with continuous electron conduction, ion diffusion channels, and good mechanical properties are particularly favorable for obtaining flexible freestanding electrodes that can realize high energy/power density, while retaining long-term cycling stability under various mechanical deformations. This Minireview focuses on recent advances in the design, fabrication, and application of nanowire-based flexible freestanding electrodes with diverse compositions, while highlighting the rational design of nanowire-based materials for high-performance flexible electrodes. Existing challenges and future opportunities towards a deeper fundamental understanding and practical applications are also presented.

Lithium–sulfur (Li–S) batteries are considered to be one of the most promising energy storage systems owing to their high energy density and low cost. However, their wide application is still limited by the rapid capacity fading. Herein, polydopamine (PDA)‐coated N‐doped hierarchical porous carbon spheres (NPC@PDA) are reported as sulfur hosts for high‐performance Li‐S batteries. The NPC core with abundant and interconnected pores provides fast electron/ion transport pathways and strong trapping ability towards lithium polysulfide intermediates. The PDA shell could further suppress the loss of lithium polysulfide intermediates through polar–polar interactions. Benefiting from the dual function design, the NPC/S@PDA composite cathode exhibits an initial capacity of 1331 mAh g−1 and remains at 720 mAh g−1 after 200 cycles at 0.5 C. At the pouch cell level with a high sulfur mass loading, the NPC/S@PDA composite cathode still exhibits a high capacity of 1062 mAh g−1 at a current density of 0.4 mA cm−2.

“…There is a large body of literature developing organic moieties to use in electrode materials, however, relatively few classes of moieties possess discharge voltages greater than 3.0 V versus Li/Li + . [7,17,19] Currently, nitroxide based radicals, [20][21][22][23] sulfur and nitrogen containing heteroaromatics, [24][25][26][27] and aromatic quinones [19,[28][29][30][31] are promising molecular architectures that exhibit high voltages in Li-ion batteries, but more suitable moieties and functional groups need to be developed to achieve organic batteries having high energy and power densities. Molecular design motifs that allow electroactive organic molecules to better interface with conductive additives would prevent electrode dissolution and increase conductivity, potentially increasing stability and rate performance.…”

The adoption of intermittent renewable power sources has placed battery technologies into the limelight, initiating a push to develop sustainable materials for energy storage that do not rely on rare or toxic elements. Organic electrode materials are made from abundant elements that are consumed in the biomass cycle, which can make large‐scale manufacturing and recycling of these materials less detrimental to the environment. Herein, we explore how organic, electroactive phosphoryl‐bridged viologens (phosphaviologens) can be composited with single‐walled carbon nanotubes (SWCNTs) and used as organic electrodes composed of sustainable/abundant materials. To this end, we have functionalized phosphaviologens that exhibit two stable and reversible reductions with pendant pyrene moieties to interface them with carbon nanotubes. The anchoring of the redox active species on the surface of SWCNTs prevents electrode dissolution, and hybrid batteries with a high voltage (1.95–3.5 V) vs. Li/Li+ using phosphaviologens as the cathode remain stable past 500 charge/discharge cycles.
