Prussian blue analogues anchored P-(Ni,Co)Se2 nanoarrays for high performance all-solid-state supercapacitor

Microwave‐assisted synthesis of CuO/MnO 2 nanocomposites for supercapacitor application

“…When b = 0.5, the reaction process is mainly controlled by a diffusion‐controlled redox reaction. When b = 1, the reaction process is mostly controlled by a surface‐controlled capacitive reaction [31]. The b ‐values of cathodic and anodic peaks are 0.603 and 0.557, respectively, indicating the diffusion‐dominated reactions of the CuO/MnO 2 electrode (Fig.…”

“…The capacitive‐controlled ( k 1 v ) and diffusion‐controlled ( k 2 v 1/2 ) reaction processes for the electrode are expressed as follows [31]: where k 1 and k 2 are constants. The k 1 (slope) and k 2 (intercept) can be obtained from the linear relationship between i ( v )/ v 1/2 and v 1/2 at different scan rates [31]. Fig.…”

Design and Fabrication of Hierarchical NiCoP–MOF Heterostructure with Enhanced Pseudocapacitive Properties

“…The derived energy and power densities are plotted in Figure 6d. The maximum energy density of 50.3 Wh kg −1 is delivered at a power density of 1011.2 W kg −1 , which is superior to some other HSCs in literatures, including CoNi-MOF//AC, [24] NiCoP nanoplates//graphene, [37] Co 0.1 Ni 0.9 P/CNF/CC||AC/CC, [44] NiCoP/NiCo-OH30//PC, [54] ZnNiCoPNF//AC, [60] NC@ SS//Fe 2 O 3 @SS, [61] P(Ni,Co)Se 2 //ZC, [62] NiCo 2 S 4 /GA//AC, [63] ZnNiPS//AC, [64] NiCoPCoP//PNGF, [65] and β-FeOOH// NiCo hydroxides/Cu(OH) 2 /CF. [66] This device also displays a power density as high as 10 550.3 W kg −1 at 29.7 Wh kg −1 within 11 s, showing a high-power nature.…”

Nanostructure Nickel-Based Selenides as Cathode Materials for Hybrid Battery-Supercapacitors

“… Zong et al (2020) , designed an electrode material with a special structure. First, the researchers used potassium permanganate to activate the activated carbon fiber cloth.…”

“…Consequently, doping is also a critical modification and performance improvement method for the cathode material of SCs. Zong et al (2020), designed an electrode material with a special structure. First, the researchers used potassium permanganate to activate the activated carbon fiber cloth.…”
