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.

Abstract Exploration of innovative strategies aiming to boost energy densities supercapacitors without sacrificing the power density and long‐term stability is great importance. Herein, highly porous nitrogen‐doped carbon spheres (NPCS) are decorated onto graphite sheets (GSs) through a hydrothermal route, followed by chemical activation. The capacitive performance NPCS then enhanced hydroquinone sulfonic acid (HSQA) incorporation in both cathodic electrolyte electrode materials. Later, with polypyrrole (PPY), which HSQA takes versatile role as conjugated polymer dopant redox additive. negative electrodes incorporating alizarin red S (ARS) anodic Finally, PPY(HQSA)@NPCS‐GS//NPCS‐GS asymmetric supercapacitor assembled tested dual system containing HQSA‐cathodic ARS‐anodic electrolytes. This device delivers remarkable 60.37 Wh kg −1 , close or even better than lead batteries. Thus, present work provides novel pathway develop high using active electrolytes for next‐generation storage applications.
