Hydrogen energy is regarded as the ultimate energy source for future human society, and the preparation of hydrogen from water electrolysis is recognized as the most ideal way. One of the key factors to achieve large‐scale hydrogen production by water splitting is the availability of highly active and stable electrocatalysts. Although non‐precious metal electrocatalysts have made great strides in...
High‐capacity anode materials (e.g., Si) are highly needed for high energy density battery systems, but they usually suffer from low initial coulombic efficiency (CE), short cycle life, and low‐rate capability caused by large volume changes during the charge and discharge process. Here, a novel dendrimer‐based binder for boosting the electrochemical performance of Si anodes is developed. The polyamidoamine...
The surface reconstruction of oxygen evolution reaction (OER) catalysts has been proven favorable for enhancing its catalytic activity. However, what is the active site and how to promote the active species generation remain unclear and are still under debate. Here, the in situ synthesis of CoNi incorporated Fe3N nanotubes (CoNi–Fe3N) on the iron foil through the anodization/electrodeposition/nitridation...
