A core–shell CoMn-P@NG heterostructure electrode demonstrated impressive performance of hydrogen evolution over a broad pH range and maintained excellent stability.
LiMn2O4 (LMO) nano-cubes with porous structure were synthesized by a template-engaged reaction using pre-synthesized Mn2O3 porous nano-cubes as a self-sacrificing template. As a lithium-ion battery cathode material, the LiMn2O4 nano-cubes...
As the electrode material of supercapacitor, MnO2 materials have attracted extensive concern and its electrochemical performance has been continuously optimized, but the kinetic analysis is rarely discussed. Herein, a-MnO2 nanowires with a uniform morphology were
synthesized by hydrothermal method, which exhibits proven electrochemical property like outstanding circulation stability, demonstrated rate performance and high specific capacitance. In addition, diffusion-controlled Faradaic procedure and surface capacitance action were calculated and analyzed
in detail.
Aqueous zinc metal batteries (AZMBs) as one of the next-generation energy storage technologies have attracted both academic and industrial attention due to their high safety, low cost, and high specific...
Utilization of two-dimensional materials containing high specific surface area and suitable pore size for electrode materials in supercapacitors is proving to be a promising strategy for energy storage and energy conversion. Transition metal oxides with high natural abundance as well
as excellent electrochemical properties have been investigated. NiO materials have been widely used as pseudocapacitors in aqueous electrolytes. However, different synthesis methods can markedly affect the electrochemical performance and lifetime of the materials. In this work, the Ni(OH)2
precursors were etched with ammonia at high temperature and pressure using a hydrothermal approach, which resulted in a material with a suitable pore size and a large number of active sites on the edge part. Electrochemical tests and characterization revealed the superiority of the materials
prepared by this synthetic method as pseudocapacitors electrode materials as well as a new synthetic idea for commercial production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
