Recent advances and challenges of current collectors for supercapacitors

Three-dimensional ternary NixCuyZnz(CO3)(OH)2 electrodes for supercapacitors: electrochemical properties and applications

“…As a result, the ASC device exhibits behavior similar to that of EDLCs. 79 The optimized ASC is significantly influenced by the electrochemical properties of graphene. The calculated specific capacities of 21.3 and 8.4 mA h g −1 at current densities of 2 and 10 A g −1 , respectively, are lower than that of only Ni x Cu y Zn z (CO 3 )(OH) 2 ternary electrode, which is also presumed to be significantly affected by the graphene electrode, as shown in Fig.…”

Rational Design of Electrode Materials for Advanced Supercapacitors: From Lab Research to Commercialization

“…The current collector, one of the main massive components in SCs, plays a key role for hindering the commercialization of lab-made advanced SCs. [98] In particular, for aqueous SCs cells, the limited electrochemical stable window of 1.23 V and incompatible current collectors seriously cut down their energy output and serving life, further hinder the grid-scale usage of aqueous SCs. [99] The current collectors of aqueous SCs studied in literatures are mainly classified into carbon and metal current collectors.…”

Exploring the electrochemical characteristics of the nucleobase-template assisted NiCo2O4 electrode for supercapacitors

“…8 The EDLC performance mostly relies on the types of electrode material and its properties such as surface area, morphology, electrical conductivity, etc. [9][10][11] In general, downscaling of materials to the characteristic nanoscale offers a large surface area, which promises for achieving higher power and energy densities relative to that of the bulk-scaled materials with the same chemical composition. 12,13 In recent years, transition metal oxides such as zinc oxide (ZnO), vanadium oxide (V 2 O 5 ), cobalt oxide (Co 3 O 4 ), ruthenium oxide (RuO 2 ), and other related materials have been extensively employed as electrode materials for supercapacitors.…”
