A hollow graphene/conducting polymer composite fiber is created with high mechanical and electronic properties used to fabricate novel fiber-shaped supercapacitors that display energy densities long life stability. The can be woven into flexible powering textiles are particularly promising for portable wearable devices.
As emerging cutting-edge energy storage technologies, aqueous zinc-ion batteries (AZIBs) have garnered extensive research attention for its high safety, low cost, abundant raw materials, and, eco-friendliness. Nevertheless, the commercialization of AZIBs is mainly limited by insufficient development cathode materials. Among potential candidates, MXene-based materials stand out as a promising option their unique combination hydrophilicity and conductivity. However, Zn2+ kinetics, structural...
MXenes with good conductivity and hydrophilicity are a new family of potential electrocatalysts (e.g., for hydrogen evolution). However, pristine usually show unsatisfactory catalytic activity compared traditional platinum group metal electrocatalysts. We introduce both phosphorus oxygen into Mo2CTx through simple phosphorization course. The phosphorized exhibit significantly improved electrocatalytic performance toward evolution reaction MXenes, dramatic decrease in overpotential (more than...
Novel core–shell sulfur quantum dots/PVK nanocomposites were synthesized by a facile two-step dissolution–precipitation method.
Silicon anodes have been considered one of the most promising anode candidates for next generation high-energy density lithium-ion batteries due to high theoretical specific capacity (4200 mAh g−1) Si. However, lithiation endows silicon with severe volume expansion effects during charge/discharge cycling. The repeated expansions not only lead pulverization particles and separation electrode materials from current collector, but also bring rupture/formation solid electrolyte interface (SEI)...

We prepared the Poly(N-vinylcarbazole)/sulfur@reduced graphene oxide (PVK/S@RGO) composites via a facile vibrating-emulsification synthesis method, which consist of cores large sulfur particles integrated into PVK conductive network and conducting shell reduced sheets. The in plays multiple roles different processes. In preparation processes, functions as dispersants to prevent from aggregating excessively size. And cycling test, could play additional electroactive binders barriers reinforce...
Abstract LiNi 1/3 Co Mn O 2 as a promising cathode material in lithium‐ion batteries was synthesized by flash/field‐assisted sintering technique for the first time. This study showed that current‐limited synthesis of could be carried out at temperatures less than 400°C only 8 minutes, compared with conventional pressureless 850°C 12 hours. X‐ray diffraction results phase evolution from precursor mixtures to final products during process and well‐layered structure without undesirable cation...

Ultrathin honeycomb-like graphene nanocomposite membrane with biosurfactant enhanced interfacial adhesion as flexible and robust cathode may show potential for next-generation high-performance Li–S batteries.
Hollow fiber electrodes based on graphene/conducting polymer are developed by J. Cheng, B. Wang, H. Peng, and co-workers to fabricate novel high-performance fiber-shaped supercapacitors. As described page 3646, the hollow composite supercapacitors have an ultra-high specific capacitance of 304.5 mF cm−2 energy density 27.1 μW h at a power 66.5 cm−2. These mechanical electrochemical properties make promising material for next-generation wearable electronics.
Flexible fiber supercapacitors are promising candidate for power supply of wearable electronics. Fabrication high-performance fibers is in progress yet challenging. The currently available graphene made from wet-spinning or electro-deposition technologies far away practical applications due to their unsatisfactory capacitance. Here we report a facile alternately dipping (AD) method coat on wire-like substrates. excellent mechanical properties the substrate with greatly diverse choices can be...
Si-based anode materials have a relatively high theoretical specific capacity and low operating voltage, greatly enhancing the energy density of rechargeable lithium-ion batteries (LIBs). However, their practical application is seriously hindered by instability active particles electrodes caused huge swelling during cycling. How to maintain stability charge transfer network interface structure Si full challenges. To address this issue, we developed novel Si@Fe3O4/AC/CNR in-situ growing...
