A drawback with lithium‐ion batteries (LIBs) lies in the unstable lithium storage which results in poor electrochemical performance. Therefore, it's of importance to improve the electrochemical functionality and Li‐ion transport kinetics of electrode materials for high‐performance lithium storage. Here, a subtle atom engineering via injecting molybdenum (Mo) atoms into vanadium disulfide (VS2) to...
The fast electrochemical kinetics behavior and long cycling life have been the goals in developing anode materials for potassium ion batteries (PIBs). On account of high electron conductivity and theoretical capacity, transition metal selenides have been deemed as one of the promising anode materials for PIBs. Herein, a systematic structural manipulation strategy, pertaining to the confine of Fe3Se...
Titanium‐based anode materials have achieved much progress with the wide studies in lithium‐ion batteries. However, these known materials usually possess high discharge voltage platforms and limited energy densities. Herein, a titanium‐based oxide of Na2TiGeO5 with layered structure, two‐dimensional lamellar frame and exposed highly active (001) facet, exhibiting good electrochemical performance in...
In article number 1905736, Wei (Alex) Wang, Xuanhui Qu, and co‐workers adopt a three‐pronged collaborative strategy via hollow nanocubes, amorphous Void@SiOx@C, in situ cross‐linked 3D network binder to maintain structural/electrode integrality. The cover art depicts a Chinese proverb which says, “everyone gathers firewood and flames high.”
Although silicon‐based materials are ideal candidate anodes for high energy density lithium‐ion batteries, the large volumetric expansion seriously damages the integrity of the electrodes and impedes commercial processes. Reasonable electrode design based on adjustable structures of silicon and strong binders prepared by a facile method is still a great challenge. Herein, a three‐pronged collaborative...
Metal organic frameworks (MOFs)‐derived porous carbon is proposed as a promising candidate to develop novel, tailorable structures as polysulfides immobilizers for lithium–sulfur batteries because of their high‐efficiency electron conductive networks, open ion channels, and abundant central ions that can store a large amount of sulfur and trap the easily soluble polysulfides. However, most central...
