Abstract The development of high energy/power density and long lifespan device is always the frontier direction attracts great research attention in energy storage fields. Zinc‐ion capacitors (ZICs), as an integration zinc‐ion batteries supercapacitors, have been widely regarded one viable future options for storage, owing to their variable system assembly method potential performance improvement. However, ZICs still locate at initial stage until now, how construct suitable systems different condition challenging. Herein, recent advance rational design reviewed order related theory including compatible principle paradigm. It starts with a systematically summary fundamental well motivation. Then, electrode materials are classified into capacitor‐type battery‐type based on mechanism, strategies progress these two‐type candidates comprehensively discussed, aiming reveal inherent relationship between devices component architecture materials. Beyond that, perspectives this emerging field also given, expecting guide construction high‐performance practical applications boost its development.

Abstract The application of alloying‐typed red phosphorus (red P) anode in potassium‐ion batteries (KIBs) with ultra‐high theoretical capacity is hindered by the limited and fast decay due to poor electronic conductivity huge volume change. Herein, a facile efficient strategy fluorine (F) doping innovatively developed modulate pore structure carbon matrix (F‐CNS) encapsulate P enhanced potassium storage capability. Theoretical calculations reveal that F induces additional defects within layer, which facilitates 4 molecules embedding into F‐doping‐induced micropores, enhances adsorption ability toward K atoms molecules, improves electrochemical kinetics assisted more charge transfer obtained from electron density difference, thus enabling robust capability for such unique Red P@F‐CNS anode. Accordingly, demonstrates outstanding cycling stability (90% retention after 800 cycles at 2A g −1 ), full cell (Red P@F‐CNS//KFeHCF) exhibits exceptional long‐term performance (129 mAh 2500 5 A only 0.014% per cycle). In situ characterizations confirm superior structural integrity carbon‐based matrix. This study offers rational design principle engineering high‐performance carbon‐supported anodes KIBs.

Nickel hydroxide has ultra-high energy storage capacity in supercapacitors, but poor electrical conductivity limits their further application. The use of graphene to improve its is an effective measure, how suppress the stacking and overall performance composite materials become a new challenge. In this work, well-designed substrate N-doped carbon nanowires with reduced oxide (NCNWs/rGO) was fabricated by growing polypyrrole (PPy) between GO nanosheets layers then calcining them at high temperatures. This NCNWs/rGO can effectively avoid rGO nanosheets, provides sufficient sites for subsequent situ growth Ni(OH)2, forming uniform stable Ni(OH)2/NCNWs/rGO material. Benefiting from abundant pores, specific surface area (107.2 m2 g-1), conductive network throughout substrate, deposited Ni(OH)2 not only realize loading ratio, also exposes more active surfaces (221.3 g-1). After comprehensive electrochemical test, it found that positive have capacitance 2016.6 F g-1 scan rate 1 mV s-1, exhibit significantly better stability. assembled Ni(OH)2/NCNWs/rGO//AC asymmetric supercapacitor could achieve density 85.2 Wh kg-1 power densities 381 W kg-1. addition, excellent stability retain 70.1% initial after 10,000 cycles. These results demonstrate feasibility using construct high-performance electrode materials, expected be promoted other materials.
