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 Nickel hydroxide-based devices, such as nickel hydroxide hybrid supercapacitors (Ni-HSCs) and nickel-metal hydride (Ni-MH) batteries, are important technologies in the electrochemical energy storage field due to their high density, long cycle life, environmentally-friendliness. Ni-HSCs combine high-power density of capacitors with making them ideal for applications requiring rapid charge discharge cycles. In contrast, Ni-MH batteries known stability, suitable sustained output. Although have been commercialized many years also extensively investigated a relatively new technology, there is no comprehensive review comparing performance mechanisms. Therefore, this aims provide detailed comparison these two devices. This comparative study focuses on three perspectives: historic development; working principles; properties both summary could offer insight into selecting appropriate specific applications, guidance materials development understanding fundamental mechanism driving performance.
