“…The activation phenomenon is related to the particle cracking due to the alloy lattice expansion upon its hydrogenation. The particle pulverization activates the electrode material by breaking the native oxide layer present at the surface of the particles and by increasing the effective surface area and the available active sites of the electrode contributing to the increased specific capacitance of the material on cycling. − …”

A unique multifunctional electrode made of well-defined highly crystalline Ni–P nanoparticles interweaved apiece to form sponge-like structure prepared by the single-step hydrothermal method. The distinct phases of interlinked nanospherical Ni–P compounds (Ni2P, Ni2P/Ni12P5, and Ni12P5) were obtained at 140 °C with different reaction time periods. The Ni2P exhibits supreme specific capacity of 206 mA h g–1 (1354 F g–1) at 5 mA cm–2, which seems to be the highest among the Ni2P reported so far. Biomass-derived activated carbon was prepared as a negative electrode (135 F g–1 at 1 mA cm–2) to fabricate a flexible supercapattery gadget, which delivered remarkable energy density and power density of 42 W h kg–1 and 2856 W kg–1 respectively, at 3 mA cm–2 even after 10000 cycles. The Ni–P coated carbon cloth has shown immense mechanical strength and durability, which was tempting to use for electrocatalytic application. Both oxygen evolution reaction and hydrogen evolution reaction trials resulted in the evolution of an enormous amount of gas bubbles with low overpotentials of 278 and 234 mV to achieve a current density of 10 mA cm–2, respectively. Hence, the dominant Ni–P electrodes were made multifunctional by demonstrating its potential application for efficient appliances.

“…Porous carbons from various synthesis routes have been explored as high-surface area electrodes for supercapacitors [14,15]. Asphalt, a petroleum waste, has been used as a precursor to high-surface area carbons that were used as electrodes in batteries and supercapacitors [16][17][18]. Asphalt is a low-cost material obtained from the heaviest fraction of crude oil.…”

A supercapacitor is an energy-storage device able to store and release energy at fast rates with an extended cycle life; thus, it is used in various electrical appliances. Carbon materials prepared above 800 °C of activation temperatures are generally employed as an electrode material for supercapacitors. Herein, we report carbon materials prepared from a low-cost petroleum waste carbon precursor that was activated using KOH, MgO, and Ca(OH)2 only at 400 °C. Electrode materials using low-temperature activated carbons were prepared with commercial ink as a binder. The cyclic voltammetry and galvanostatic charge–discharge were employed for the electrochemical performance of the electrodes, and studied in a 3-electrode system in 1 M solutions of potassium nitrate (KNO3) as electrolyte; in addition, the supercapacitive performance was identified in a potential window range of 0.0–1.0 V. The best-performance activated carbon derived from vacuum residue with a specific surface area of 1250.6 m2/g exhibited a specific capacitance of 91.91 F/g.

“…Therefore, the prepared carbon materials by coal-derived asphaltene as precursor are easier graphitized, which makes it promising to prepare porous carbons with excellent electrical conductivity for using as electrode materials. The carbon materials derived from asphaltene, for example, active carbon [207][208][209] , carbon foam [210,211] , carbon nanosheets [212] , carbon fibers [213,214] , and versatile composite or doped carbon materials [208,215,216] , which successfully applied in water purification, gas adsorption, electrodes, etc. The intensive interfacial interaction between functionalized asphaltenes and epoxy resins produced a novel reinforcing filler with significantly increased storage modulus [155] .…”
