Highly flexible porous carbon nanofibers (P-CNFs) were fabricated by electrospining technique combining with metal ion-assistant acid corrosion process. The resultant fibers display high conductivity and outstanding mechanical flexibility, whereas little change in their resistance can be observed under repeatedly bending, even to 180°. Further results indicate that the improved flexibility of P-CNFs due graphitization degree caused Co ions. In view electrode materials for high-performance...

The use of a lithium metal anode enables batteries with significantly higher energy density, but at the expense growth dendrites that trigger internal short circuits, induce safety risks, and reduce cycle stability. To address this challenge, here, we report design an aluminum fluoride nanowire membrane as conversion interlayer to regulate deposition for more stable safe batteries. generates LiF-rich solid electrolyte interphase alloy nanoparticles in contact offer active sites guiding...

Abstract Aqueous asymmetric supercapacitors (ASCs) may offer comparable or higher energy density than electric double‐layer capacitors (EDLCs) based on organic electrolytes. As such, ASCs be more suitable for integration into smart textiles, where the use of flammable solvents is not acceptable. However, reported ASC devices typically suffer from poor rate capability and low areal loadings. This study demonstrates development nitrogen‐doped carbon (N‐C) nanowire/metal oxide (Fe 2 O 3 MnO )...
Abstract The development of low‐cost, high‐energy cathodes from nontoxic, broadly available resources is a big challenge for the next‐generation rechargeable lithium or lithium‐ion batteries. As promising alternative to traditional intercalation‐type chemistries, conversion‐type metal fluorides offer much higher theoretical capacity and energy density than conventional cathodes. Unfortunately, these still suffer irreversible structural degradation rapid fading upon cycling. To address...
Nanostructured metal sulfides with excellent electrochemical activity and electrical conductivity are particularly promising for applications in high-performance energy storage devices. Here, we report on the facile synthesis of nanostructured CuS networks composed interconnected nanoparticles as novel battery-type materials asymmetric supercapacitors. We find that exhibit a high specific capacity 49.8 mA g(-1) at current density 1 A g(-1), good rate capability cycle stability. The superior...

Abstract Lithium–metal fluoride batteries promise significantly higher energy density than the state‐of‐the‐art lithium‐ion and lithium–sulfur batteries. Unfortunately, commercialization of metal cathodes is prevented by their high resistance, irreversible structural change, rapid degradation. In this study, a substantial boost in (MF) cathode stability designing nanostructure with two layers protective shells—one deposited ex situ other demonstrated. Such methodology achieves over 90%...
Benefitting from large space and semiconductor properties of PTCDI, a PTCDI electrode was constructed for PIBs. The displays an excellent performance in optimized electrolytes which can be attributed to fast electron ion transport kinetics.
Magnesium–sulfur (Mg-S) batteries are emerging as a promising alternative to lithium-ion batteries, due their high energy density and low cost. Unfortunately, current Mg-S typically suffer from the shuttle effect that originates dissolution of magnesium polysulfide intermediates, leading several issues such rapid capacity fading, large overcharge, severe self-discharge, potential safety concern. To address these issues, here we harness copper phosphide (Cu3P) modified separator realize...
Lithium-ion batteries (LIBs) dominate the market of rechargeable power sources. To meet increasing demands, technology updates focus on advanced battery materials, especially cathodes, most important component in LIBs. In this review, we provide an overview development materials and processing technologies for cathodes from both academic industrial perspectives. We briefly compared fundamentals cathode based intercalation conversion chemistries. then discussed with specific focuses...
Abstract Li‐ion hybrid supercapacitors (Li‐HSCs) hold great promise in future electrical energy storage due to their relatively high power and density. However, a major challenge lies the slow kinetics of intercalation/extraction within metal‐oxide electrodes. Here, it is shown that ultrafast charge realized by confining anatase TiO 2 nanoparticles carbon nanopores enable high‐rate anode for Li‐HSCs. The porous with interconnected pore walls open channels not only works as conductive host...
