Searching for new‐type cathodes to enhance the capacity of Na‐ion batteries is one of the hot spots in energy storage systems. Many sodium insertion transition metal oxides, i.e., Na‐Mn‐O compounds, are intensively studied owing to their high voltage, abundant resources, and low toxicity....
Developing low‐cost, highly active, and stable bifunctional electrocatalysts is a challenging issue in electrochemical water electrolysis. Building on 3D architectured electrocatalysts through structural and compositional engineering is an effective strategy to enhance catalytic activities as...
Bismuth‐based ternary halides have recently gained a lot of attention as lead‐free perovskite materials. However, photovoltaic performances of these devices remain poor, mostly due to their low‐dimensional crystal structure and large bandgap. Here, a dynamic hot casting technique to fabricate...
The lithium metal battery (LMB) is among the most sought‐after battery chemistries for high‐energy storage devices. However, LMBs usually undergo uncontrollable lithium deposition and severe side reactions, which significantly impede their practical applications. Herein, a stable Al2O3‐based...
Titania is one of the key materials used in 1D, 2D, and 3D nanostructures as electron transport media in energy conversion devices. In the present study, it is shown that the electronic properties of TiO2 nanotubes can be drastically improved by inducing a nanotwinned grain structure in the...
Transition metal oxides (TMOs) possess high theoretical capacity and serve as promising anode candidates for lithium‐ion batteries. However, the intrinsic low conductivity handicaps the application of TMOs. Molecular modification by coupling TMOs structure with Li‐ion conductive polymer ligands...
