Abstract Highly conductive metal selenides are gaining prominence as promising electrode materials in electrochemical energy‐storage fields. However, phase‐pure bimetallic scarcely retrieved, and their underlying charge‐storage mechanisms still far from clear. Here, first a solvothermal strategy is devised to purposefully fabricate monodisperse hollow NiCoSe 2 (H‐NiCoSe ) sub‐microspheres. Inherent formation of metallic H‐NiCoSe tentatively put forward with comparative structure‐evolution...
Abstract Sodium‐ion batteries (SIBs) are regarded as next‐generation secondary and complement to lithium‐ion (LIBs) for large‐scale electrochemical energy storage applications due the abundant availability, even distribution, cost‐effectiveness of raw sodium resources. The phosphate‐based polyanions stand out various cathode material owing their high operation voltage, stable structure, superior safety, excellent sodium‐storage properties. undesirable electric conductivities specific...
Abstract LiFePO4 (lithium iron phosphate (LFP)) is a promising cathode material due to its environmental friendliness, high cycling performance, and safety characteristics. On the basis of these advantages, many efforts have been devoted increasing specific capacity high-rate satisfy requirement for next-generation batteries with higher energy density. However, improvement LFP mainly affected by dynamic factors such as low Li-ion diffusion coefficient poor electrical conductivity. The...
The use of TiNb2O7 (TNO) as an anode material for Li-ion battery is attracting tremendous attention because its stable structure and high theoretical capacity. However, the inherent poor electronic conductivity ionic restrict practical application. Herein, we designed prepared zirconium-doped nanospheres (Zrx-TNO NSs, x = 0, 0.05, 0.010) with pores through a simple hydrolysis method to adjust lattice spacing electron distribution. nanosphere-structured materials can not only prevent...
In this study, we developed a cost-effective mechanical ball milling refinement method for Si-based composite anodes in LIBs, demonstrating capacity retention of 79.5% over 280 cycles and suggesting significant improvement electrochemical performance.
Transition metal phosphide (TMP)-based anode materials for lithium-ion batteries (LIBs) have garnered significant attention due to their high theoretical specific capacity and cost-effectiveness, yet they suffer from volume changes pulverization during cycling. Herein, an advanced heterostructural FeP/SnP@C material was synthesized applied as the tackling key issues. The composite comprises ultrathin nanosheets arranged in a hydrangea-like morphology, boasting substantial surface area toward...
TiO2-coated Fe2O3 composites exhibiting high electrochemical stability with oxygen defects were synthesized as the anode materials of Li-ion batteries using an easy sol–gel method. The industrial submicron-sized no special shape and commercial tetrabutyl titanate adopted raw materials. phase structures, morphologies, elements distribution on surface characterized by X-ray diffraction analysis, electron paramagnetic resonance, scanning microscopy, photoelectron spectroscopy, so forth. Results...
Chalcopyrite ZnSiP 2 has emerged as a promising anode material for next generation Li-ion-based batteries due to its high theoretical capacity. First principles multiple-dopant effect computations were made on the structural, electronic, magnetic, and thermodynamic responses chalcopyrite 2(1−x) Sb x , Bi Zn (1−x) Ba SiP 1−x using both norm conserving, ultra-soft pseudopotentials with generalized gradient approximation (GGA+PBE) main frame of density functional theory.

Severe volume expansion and poor ionic transport greatly impede the further application of micro-Si anodes despite their high energy density low processing cost. To address these challenges, we propose a Si/C composite anode (denoted as WM-30C). In this design, wet milling introduces an oxide layer core, while high-temperature heat treatment with bitumen regulates silicon valence state strong Si–C bond, forming shell. during process micro-Si, is introduced in situ on surface to form Si@SiO2...
