Enhancing the low‐potential capacity of anode materials is significant in boosting the operating voltage of full‐cells and constructing high energy‐density energy storage devices. Graphitic carbons exhibit outstanding low‐potential potassium storage performance, but show a low K+ diffusion kinetics. Herein, in situ defect engineering in graphitic nanocarbon is achieved by an atomic self‐activation...
Potassium‐Ion Full‐Cells
In article number 2302037, Yaxin Chen and co‐workers present an in‐situ defect engineering strategy in carbon to boost the accessible low‐voltage insertion for advanced potassium‐ion full‐cells. The defects in the carbon layers provide channels for accessible and fast potassium ions diffusion to enhance the potassium storage performance. This work provides some ideas for carbon...
Macroscopic 3D porous materials are ideal solar evaporators for water purification. However, the limited sunlight intensity and penetrating depth during solar‐driven evaporation cannot prevent the biofouling formation by photothermal effect, thus leading to the deterioration of evaporation rate. Herein, a magnetic heating strategy is reported for anti‐biofouling solar steam generation based on a magnetic...
