Abstract Transition Metal Phosphides (TMPs) are highly focused on as electrode materials for their potential applications in electrochemical energy storage and conversion (EESC) devices due to high theoretical capacity, carrier mobility, excellent chemical mechanical stability. However, pristine TMPs typically suffer from low device stability safety concerns sluggish electronic/ionic kinetics volumetric variation after prolonged cycling. The precise morphological design synthesis of with good dispersity, novel assembling techniques, mitigation approaches, emphasizing nanoarchitectonics engineering, opens up new frontiers overcome these challenges. This paper comprehensively reviews state‐of‐the‐art advances TMP‐based key materials, focusing geometric electronic structure modulation, EESC, including rechargeable batteries, supercapacitors, electrocatalysis. In the end, current technical future research prospects nanostructured have also been presented EESC applications.

Abstract The designing and searching superior anode materials with low operation potential rapid redox kinetics is of paramount importance. Incorporating transition metal (TM) into phosphorus to form TM phosphides combining them low‐dimension represents effective strategy for enhancing the electrochemical performances. Herein, a 3D network FeP@MXene composite proposed exhibiting high reversible capacity 444.1 mAh g −1 at current density 500 mA after cycles lithium‐ion batteries. study reveals that exceptional cycling stability originates from synergistic combination specific surface area structural design buffering volume expansion. Specifically, Prussian blue (PB) derived cubic structures are uniformly dispersed within interwoven MXene nanosheets. Notably, pseudocapacitive dominated fast lithium storage this active material induces incomplete intercalation during initial cycles. This mechanism effectively circumvents severe decay observed in conventional phosphides, which arises heterogeneous induced fluctuations. work provides novel perspectives insights rational high‐performance phosphide anodes.

Abstract Aqueous zinc ion batteries (AZIBs) are a potential energy storage device due to their low cost and environmental friendliness. However, the problems of Zn metal anode lead coulombic efficiency safety problems, thus hindering practical application AZIBs. Therefore, developing zinc‐metal free materials can effectively avoid problems. Herein, an intercalation‐assisted in situ exfoliation mechanism is reported obtain Cu 2 Se nanosheets (E‐Cu Se) during electrochemical reaction. The good conductivity ensures rapid (de)intercalation ions excellent charge transport properties Se. Furthermore, not only has strong structural stability itself but also inhibit dendrite through conversion copper between cathode anode. results show that E‐Cu electrode intercalation (≈0.4 V) high specific capacity 284.8 mAh g −1 after 100 cycles at 0.1 A . Meanwhile, “rocking‐chair” aqueous zinc‐ion battery assembled with x MnO as delivers 40 60 000 cycles. discussed based on various characterization techniques theoretical calculations. This study expected provide new avenue for development high‐performance
