Electrochemical energy storage devices, such as supercapacitors and batteries, have been proven to be the most effective conversion technologies for practical application. However, further development of these devices is hindered by their poor electrode performance. Carbon materials used in batteries are often derived from nonrenewable resources under harsh environments. Naturally abundant biomass a green, alternative carbon source with many desired properties. This review article presents...
With rising energy concerns, efficient conversion and storage devices are required to provide a sustainable, green supply. Solar cells hold promise as due their utilization of readily accessible solar energy; however, the output can be non-continuous unstable. Therefore, it is necessary combine with compatible realize stable power To this end, supercapacitors, highly devices, integrated mitigate fluctuations. Here, we report on development cell-supercapacitor hybrid device solution...
Activated cotton textile (ACT) with porous tubular fibers embedded NiS2 nanobowls and wrapped conductive graphene sheets (ACT/NiS2–graphene) was fabricated by a simple two-step heat treatment method. When used as binder-free electrode, the ACT/NiS2–graphene electrode exhibited an exceptional electrochemical performance including ultrahigh initial discharge capacity (∼1710 mAh g–1 at 0.01 C), magnificent rate (the capacitance retained ∼645 1 C after 100 cycles) excellent cyclic stability...

Single-atom catalysts with well-defined atomic structures and precisely regulated coordination environments have been recognized as potential substitutes for natural metalloenzymes. Inspired by the metal structure of enzymes, we show here that oxidase-like activity single-atom Co greatly depends on their local N around catalytic sites. We synthesized a series different nitrogen numbers (Co–Nx(C), x = 2, 3, 4) demonstrated could be effectively tailored fine-tuning coordination. Among studied...

ConspectusNanozymes are nanomaterials with intrinsic enzyme-like properties that can overcome the current limitations of natural enzymes, such as high preparation cost, instability, restricted application scenarios, etc. Since Fe3O4 nanoparticles (NPs) were shown to possess peroxidase (POD)-like activity in 2007, thousands reported mimic catalytic various types enzymes including catalase (CAT), haloperoxidase, superoxide dismutase (SOD), glucose oxidase, glutathione peroxidase, hydrolase,...
Abstract The lithium–sulfur (Li–S) battery is a promising candidate for next‐generation high‐density energy storage devices because of its ultrahigh theoretical density and the natural abundance sulfur. However, practical performance sulfur cathode plagued by fast capacity decay poor cycle life, both which can be attributed to intrinsic dissolution/shuttling lithium polysulfides. Here, new built‐in magnetic field–enhanced polysulfide trapping mechanism discovered introducing ferromagnetic...
Sodium‐ion batteries are promising for grid‐scale storage applications due to the natural abundance and low cost of sodium.
