Abstract Constructing electrode materials with fast ions and electrons transport channels is an effective solution to achieve high‐power‐density long‐cycle potassium‐ion batteries (PIBs). Herein, completely opening radial pores in N/O dual‐doped carbon nanospheres (RPCNSs) are constructed as anode for high‐power PIBs. The RPCNS hierarchical structure (micro/meso/macropores channels) dual‐doping permits speedy transportation within the anode, achieving a reversible capacity of 346 mAh g −1 at...
Abstract Potassium‐ion hybrid capacitors (PIHCs) show great potential in large‐scale energy storage due to the advantages of electrochemical and potassium‐ion batteries. However, their development remains at preliminary stage is mainly limited by kinetic imbalance between two electrodes. Herein, an architecture NbSe 2 nanosheets embedded N, Se co‐doped carbon nanofibers (NbSe /NSeCNFs) as flexible, free‐standing, binder‐free anodes for PIHCs reported. The /NSeCNFs with hierarchically porous...
The LoRaWAN based Low Power Wide Area networks aim to provide long-range connectivity a large number of devices by exploiting limited radio resources. Adaptive Data Rate (ADR) mechanism controls the assignment these resources individual end-devices runtime adaptation their communication parameters when quality links inevitably changes over time. This paper provides detailed performance analysis ADR technique presented in recently released LoRaWan Specifications (v1.1). We show that lacks...
The corrosion of Li- and Mn-rich (LMR) electrode materials occurring at the solid-liquid interface will lead to extra electrolyte consumption transition metal ions dissolution, causing rapid voltage decay, capacity fading, detrimental structure transformation. Herein, a novel strategy is introduced suppress this by designing an Na
Abstract Lithium metal batteries are highly desired for durable and high‐power energy storage devices due to high theoretical capacity lowest redox potential. Nevertheless, activity of Li, large volume change, Li dendrite formation during cycling severely hinder their further application.

Metal-organic frameworks (MOFs) with inherent porosity, controllable structures, and designable components are recognized as attractive platforms for designing advanced electrodes of high-performance potassium-ion batteries (PIBs). However, the poor electrical conductivity low theoretical capacity many MOFs lead to inferior electrochemical performance.

Abstract Rechargeable magnesium batteries (RMBs) have garnered considerable interest from researchers and industries owing to their abundant resources, cost‐effectiveness, impressive energy density, safety features, positioning them as a compelling technology for sustainable energy. Chalcogenides, with high electrochemical activity low charge facilitate the diffusion migration of Mg 2+ . “Soft” anionic lattices, such S or Se, weaken Coulombic attraction between crystal structure , thereby...
Potassium-ion hybrid capacitors (KIHCs) have attracted growing attention due to the natural abundance and low cost of potassium. However, KIHCs are still limited by sluggish redox reaction kinetics in electrodes during accommodation large-sized K+.

The hierarchical structure rich doped nitrogen SHPNC result...
The two major limitations in the application of SnO2 for lithium-ion battery (LIB) anodes are large volume variations during repeated lithiation/delithiation processes and a irreversible capacity loss first cycle, which can lead to rapid fade unsatisfactory initial Coulombic efficiency (ICE). To overcome these limitations, we developed composites ultrafine nanoparticles situ formed Co(CoSn) nanocrystals embedded an N-doped carbon matrix using Co-based metal–organic framework (ZIF-67). Co...
Lithium selenium (Li-Se) batteries have attracted increasing interest for its high theoretical volumetric capacities up to 3,253 Ah L−1.
