“…However, the LIBs based on the graphite anodes are not sufficient to satisfy the increasing energy needs in modern society. Therefore, the development of more anode material at a higher capacity becomes necessary. − Among the proposed non-carbon anode materials, such as lithium–titanium composites, silicon-based materials, transition metal oxides, and other innovative alloy materials, transition metal oxides (TMOs) with high specific capacity are considered potential alternative anode materials. − TMOs are concentrated in the oxides of metals, such as Mn, Fe, and Cu, and most of them can represent a excellent reversible capacity twice that of commercial graphite. − As TMOs, the theoretical specific capacity of copper oxide (CuO) compounds is up to 674 mAh g –1 together with non-toxic and simple synthesis, making it a potential anode material for LIBs. − However, CuO suffers a large volume expansion of 174% upon the electrochemical process and low electronic conductivity, which hamper the application of CuO anodes. − To overcome the above issues, incorporating carbonaceous materials is a simple and effective strategy. − Recently, Zhou et al designed the CuO/graphene composites with a microwave-assisted assemble method. The CuO nanoleaf enables effective separation between adjacent graphene sheets; meanwhile, graphene prevents aggregation and comminution of the CuO nanoleaf .…”

Copper oxide is considered as a potential anode material for lithium-ion batteries (LIBs), which have attracted huge amounts of research ardor owning to the high capacity and ultrahigh theoretical capacity, twice that of a graphite anode. However, the practical application of the copper oxide anodes is hindered by their inherent properties, including low conductivity and huge volume variation of active materials during the lithiation reaction. Consequently, a novel CuO/Cu 2 O/coal-based reduced graphene oxide nanosheet composite (CCO/CRGO) with porous structure and conductive network was constructed via a mild solvothermal self-assembly method. Thanks to the unique structure, which facilitates the electronic transference and ion diffusion while also easing the volume expansion of copper oxides, the obtained CCO/CRGO anode exhibits a higher reversible capacity of 586 mAh g −1 at 1 A g −1 with impressive stability, and the capacity restored to 767 mAh g −1 when the current density reduced to 0.1 A g −1 . Electrochemical kinetic analysis of CCO/CRGO indicates that the capacitive contribution is the most of the capacity stems, which can improve the rate performance of the CCO/CRGO electrode. Considering the desirable electrochemical performance and the simple synthesis route, CCO/CRGO may be a candidate when used as an anode material for high-rate LIBs.

“…[251,252] Yet, there are three main issues of CuO, namely, low electrical conductivity, slow diffusion, and large volume expansion during discharge-charge processes, which hinder their wide applications. [253][254][255] Effective preparation techniques help to obtain materials with unique microstructure and morphology and improve the electrochemical performance. [256] A facile frequency reactive magnetron sputtering method has been applied to synthesize CuO thin films with a high reversible capacity by Pecquenard et al [257] Similar work was carried out by Chen et al who synthesized CuO thin films as the anode materials.…”

extensive interest, [1][2][3] such as SCs, [4] rechargeable ion batteries, [5] water splitting, [6] metal-air batteries, [7] and CO 2 RR. [8] However, the practical applications of SCs and rechargeable ion batteries are limited by low energy density and low power density, respectively. [9,10] The multiple-electron transfer reactions in water splitting have posed a significant challenge that limits the catalytic efficiency and cycle stability. [11] At present, the urgent issue of metal-air battery is to design high-performance bifunctional electrodes. [12] For CO 2 RR, the technical realization is limited by the activity and selectivity of the catalyst, and the selectivity of its product beyond that of CO. [13,14] In these electrochemical devices, electrodes represent the core component, which dictates the efficiency, energy and power density, as well as catalytic activity and durability.Since the birth of graphene, 2D materials have attracted great attention due to their unique electrochemical, mechanical, and optical properties and diverse applications, as manifested in over 3000 academic papers each year. [15,16] 2D materials possess some structural advantages over the 0D and 1D counterparts by interlayer gap bonding and weak out-of-plane Van der Waals interaction, which provides an interesting platform for energy storage and conversion research. [17,18] So far, the 2D material family mainly includes transition metal dichalcogenides, transition metal carbides, layered metal oxides, layered double hydroxides and other graphene-like materials, such as black phosphorus. Of these, copper-based materials have received extensive attention because of high natural abundance, low price, high strength, arc erosion resistance, easy preparation of various nanoshapes, wear resistance, etc. (Figure 1), [19,20] leading to excellent electrochemical performance and advancement of electrochemical energy storage and conversion (Figure 2). For example, with a large surface area and potential size effect, CuO nanostructures, a p-type semiconductor, have excellent physical and chemical properties for SCs, as well as interesting magnetic and superhydrophobic properties, as compared with other metal oxides, such as TiO 2 , ZnO, WO 3 , and SnO 2 . [21] Cu-S compounds are a promising lithium cathode with a high energy density and long cycling stability. [22] Cu-Se is also considered as a novel cathode 2D materials have shown great potential as electrode materials that determine the performance of a range of electrochemical energy technologies. Among these, 2D copper-based materials, such as Cu-O, Cu-S, Cu-Se, Cu-N, and Cu-P, have attracted tremendous research interest, because of the combination of remarkable properties, such as low cost, excellent chemical stability, facile fabrication, and significant electrochemical properties. Herein, the recent advances in the emerging 2D copper-based materials are summarized. A brief summary of the crystal structures and synthetic methods is started, and innovative strategies for improving electro...
