“…The values of C s gradually decrease with an increase in current densities from 1 to 11 A g −1 . This can be ascribed to the fact that with the high current rate, an asynchronous shuttling of charges takes place which leads to lowering the rate of diffusion/migration of electrolyte ions . The value of C s for SiC/BiCoZnO composite is decreased to 337.3 C g −1 with a retention value of 40.1% at 11 A g −1 , whereas the values of C s for SiC and BiCoZnO were decreased to 98.1 C g −1 (49%) and 22.8 C g −1 (6.6%), respectively.…”

“…It is noted that, from these figures, the nature of charge–discharge curves is retained by all the materials even at varying current densities affirming their excellent electrochemical reversibility. Due to the predominant faradaic or battery‐like charge storage mechanism of SiC/BiCoZnO composite, the amount of charge stored in electrode materials by computing the specific capacity ( C s ) in terms of C g −1 or mAh g −1 is given using the formula belowCnormals=Im×Δtwhere “ I ” denotes discharge current (A), “Δ t ” stands for discharge time (s), and “ m ” is the mass of active material ( g ). The estimated specific capacities of the pristine SiC, BiCoZnO, and SiC/BiCoZnO composite electrodes are 197.8, 343.2, and 841.1 C g −1 , respectively, at the current density of 1 A g −1 .…”

“…In all the three cases, the CV curves reveal a characteristic redox peak. Since, the electrode is a battery type Faradic material, the terminology behind the charge storage has been reported elsewhere 9,20 . The CV traces indicate excellent electrochemical reversibility of the AgCoO 2 À Co 3 O 4 /C electrodes.…”

“…However, they require an enormous amount of power to work as an autonomous or complement distinctive vitality sources such as batteries and fuel cells . Supercapacitors are commonly divided into two types namely porous carbon‐based non‐Faradic electrical double‐layer capacitors and metal oxide/sulfides‐based reversible faradaic pseudocapacitors . In recent decades, various types of transition metal sulfides (TMSs) have been examined beyond the state‐of‐art of materials, which showed exceptional energy storage performance compared to the former generation materials, including metal oxides and carbon‐based materials.…”
