“…[ 1,2 ] Particularly, TSCs have attracted great attention because they not only retain the advantages of supercapacitors (SCs) including high cyclic stability, high power density and environmental friendliness, but also exhibit extraordinary knittability and weavability, which are very promising power source for wearable electronics. [ 3–5 ] Generally speaking, the electrodes of TSCs are built on the linear supports such as carbonaceous fibers/yarns (e.g., carbon fibers, carbon nanotube yarns and graphene fibers), [ 6–8 ] metal wires/yarns (e.g., stainless steel yarns (SSY), Au wires and Cu wires) [ 9–11 ] and textile yarns (e.g., cotton yarns, polyester yarns and nylon yarns), [ 12–14 ] and then various active materials are coated on the surface of the linear supports to provide/improve capacitance. Among these supports, linear metal materials are of great interest due to their ultrahigh electrical conductivity, allowing them function as current collectors at the same time.…”

A flexible symmetric thread‐like supercapacitor (TSC) with high operating voltage window and good electrochemical performance is manufactured, that fulfills the requirements of wearable electronics. First, iron oxide (Fe2O3) nanosheets are directly grown in situ on the surface of stainless steel yarn (SSY) by an acid corrosion and self‐oxidation process, and then a polypyrrole (PPy) coating is covered on the surface of Fe2O3 nanosheets via chemical oxide method to obtain the thread‐like PPy@Fe2O3@SSY composite electrode. The electrode achieves a wide potential range of −1.0–0.8 V (versus Ag/AgCl) and a high areal specific capacitance of 667.8 mF cm−2 with outstanding galvanostatic charge/discharge cycling stability of 87.5% capacitance retention after 10 000 cycles in 1 m lithium sulfate (Li2SO4) aqueous solution. The symmetric TSC based on the PPy@Fe2O3@SSY electrode and carboxymethyl cellulose sodium salt/Li2SO4 gel electrolyte exhibits a wide operating voltage window of 1.8 V, and its maximum energy density can reach 39.3 μWh cm−2. Additionally, the TSC demonstrates excellent electrochemical performance under various bending states and a bending cycling test. The preparation method and raw materials are low‐cost and scalable, and the overall performance of the TSC is excellent, which makes this device a promising energy storage device for wearable electronics.

“…Furthermore, TMP materials are considered to be stable electrodes due to their favorable resistance to the surrounding environment and good thermal stability. [ 32 ] Bimetallic phosphides, like NiCoP, [ 34,122 ] Co x Ni 1− x P, [ 32 ] NiCuP, [ 124 ] and FeNiP, [ 111 ] have been prepared as flexible battery‐type electrodes for SCs due to their large charge‐storage ability. Intriguingly, Wang's group [ 122 ] prepared 3D cactus‐like NiCoP/NiCo–OH on CC as a flexible SC electrode, which integrated both transition metal phosphide and hydroxide materials.…”

Flexible and stretchable supercapacitors (FS‐SCs) are promising energy storage devices for wearable electronics due to their versatile flexibility/stretchability, long cycle life, high power density, and safety. Transition metal compounds (TMCs) can deliver a high capacitance and energy density when applied as pseudocapacitive or battery‐like electrode materials owing to their large theoretical capacitance and faradaic charge‐storage mechanism. The recent development of TMCs (metal oxides/hydroxides, phosphides, sulfides, nitrides, and selenides) as electrode materials for FS‐SCs are discussed here. First, fundamental energy‐storage mechanisms of distinct TMCs, various flexible and stretchable substrates, and electrolytes for FS‐SCs are presented. Then, the electrochemical performance and features of TMC‐based electrodes for FS‐SCs are categorically analyzed. The gravimetric, areal, and volumetric energy density of SC using TMC electrodes are summarized in Ragone plots. More importantly, several recent design strategies for achieving high‐performance TMC‐based electrodes are highlighted, including material composition, current collector design, nanostructure design, doping/intercalation, defect engineering, phase control, valence tuning, and surface coating. Integrated systems that combine wearable electronics with FS‐SCs are introduced. Finally, a summary and outlook on TMCs as electrodes for FS‐SCs are provided.

“…Composite electrode materials have attracted extensive research interest owing to the advantages of the synergistic effect and optimized electrochemical properties [70,71]. In detail, carbon materials with electrical double-layer behavior possess excellent cycling stabilities and robust rate properties, but suffer from the low specific capacitance, while, conducting polymer, metal oxide, or sulfide based pseudo capacitors exhibit high specific capacitance but sustain poor cycling and rate stabilities [72][73][74][75][76][77][78][79][80]. As a result, the composites combined with both the two kinds of electrode materials could exploit their advantages to the full, thus achieving the flexible on-chip MSC with the possibility of practical application [81][82][83][84].…”
