Because of their apparent and intrinsic advantages—including their high-power density and
high-rate capability, which result from their high surface areas, appropriate pore …

With the increasing energy demand and the overconsumption of fossil fuels, renewable
energy-storage devices with higher efficiency are of great interest. In particular …

Abstract Herein, the MnCo 2 O 4.5 microflowers (MFs) assembled by two-dimensional (2D)
porous nanosheets were prepared through an initial solvothermal reaction with a …

Supercapacitors represent a major technology to store energy for many applications
including electronics, automobiles, military, and space. Despite their high power density, the …

A binder-free electrode with metallic Co embedded in N-doped carbon nanotube array
(Co@ N-CNT) was fabricated via an electrodeposition, stereoscopic assembly and self …

Recently, transition metal oxides, such as ruthenium oxide (RuO2), manganese dioxide
(MnO2), nickel oxides (NiO) and cobalt oxide (Co3O4), have been widely investigated as …

Since the ability of ionic liquid (IL) was demonstrated to act as a solvent or an electrolyte, IL-
