The natural insulating property and notorious pulverization of volume variation‐induced materials during cycling pares the electrochemical activity of red phosphorous (RP) for lithium/sodium‐ion batteries (LIBs/SIBs). To work out these issues, a tailored trimodal porous carbon support comprising highly ordered macropores and micro‐mesoporous walls embedded with copper (Cu) nanoclusters (Cu‐OMC) is...
Lithium batteries with high electrode thickness always possess a poor battery property due to electrode polarization along the thickness direction. Herein, a concept that the electrode polarization can be reduced through the fabrication of 3D ordered interconnected nanostructure in the electrode is put forward. A nitrogen‐doped carbon photonic crystal (NCPC) with the ordered interconnected nanostructure...
Freestanding bifunctional electrodes with outstanding oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) properties are of great significance for zinc–air batteries, attributed to the avoided use of organic binder and strong adhesion with substrates. Herein, a strategy is developed to fabricate freestanding bifunctional electrodes from the predeposited nickel nanoparticles (Ni‐NCNT)...
In article number 1804930, Xiaobin Hu and co‐workers demonstrate a two‐layer ferroelectric heterojunction, in which BiFeO3 acts as the 3D macroporous skeleton and LiNbO3 as the passivation layer. This photoanode exhibits a tremendous enhancement of photocurrent density in a HCO3‐/CO2 system. Photoelectrochemical impedance spectroscopy suggests that the synergistic effect of the skeleton and passivation...
Photoelectrochemical carbon dioxide conversion to fuels such as carbon monoxide, methanol, and ethylene exhibits great potential to solve energy issues. Unfortunately, CO2 conversion efficiency is still low due to violent charge recombination at the photoanode. Herein, a novel 3D macroporous ferroelectric heterojunction composed of BiFeO3 and LiNbO3 is developed by a template‐assisted sol–gel method,...
Phase change Materials (PCMs) have a promising future in the energy fields of latent heat storage, solar energy conversion and building thermal management. In this work, two types of reduced graphene oxide (rGO) with different diameters were prepared and combined with paraffin, octadecanol and stearic acid PCMs, respectively. The one-pot hydrothermal method was employed for the synthesis of three-dimensional...
The insulator of the sulfur cathode and the easy dendrites growth of the lithium anode are the main barriers for lithium–sulfur cells in commercial application. Here, a 3D NPC@S/3D NPC@Li full cell is reported based on 3D hierarchical and continuously porous nickel photonic crystal (NPC) to solve the problems of sulfur cathode and lithium anode at the same time. In this case, the 3D NPC@S cathode...
