Sodium‐ion batteries (SIBs) represent a viable substitute to lithium‐ion batteries due to their affordability and resource abundance. For SIBs, antimony (Sb) shows potential as anode material but is impeded by the high volumetric variations. Here the challenges of Sb sodium storage by introducing the nanostructured Cu substrate for enhanced Sb adhesion and morphology optimization is addressed, which...
Light‐driven microrobots with different propulsion mechanisms have attracted great attention in microrobot synthesis and applications. However, current systems rely heavily on precious metals, using a complex synthesis process and limited working wavelength. It is therefore of great interest to fabricate microrobots that can be driven by multi‐wavelength irradiation and with simple components. Here,...
Aqueous rechargeable zinc‐ion batteries (ARZIBs) are promising energy storage systems owing to their ecofriendliness, safety, and cost‐efficiency. However, the sluggish Zn2+ diffusion kinetics originated from its inherent large atomic mass and high polarization remains an ongoing challenge. To this end, electrodes with 3D architectures and high porosity are highly desired. This work reports a rational...
