“…Similarly, CuS dandelion-like clusters were synthesized by a simple colloidal approach. 127 The authors were able to obtain such a structure by varying the solvent. When employed as an electrode in LIBs, electrochemical data indicated improved performance delivering 420 mAh g −1 at 1.12 A g −1 , and at 0.56 A g −1 , the capacity was as high as 500 mAh g −1 with good capacity retention.…”

Currently, different metal sulfides (NiS, Co 9 S 8 , FeS 2 , and CuS) have been extensively studied as alternative electrodes for rechargeable batteries that can satisfy the performance requirements for more powerful energy supply and storage technologies for various applications and industries. Among them, copper sulfides have gained significant attention as a promising electrode material in rechargeable metal-ion (Li, Mg, Na, and Al) batteries. A wide range of synthesis routes and methods have been implemented in order to prepare various stoichiometry Cu x S (1 ≤ x ≤ 2) micro-/nanostructured materials with excellent electrochemical properties. Since the bulk microsized electrode materials have almost reached their performance limits for energy devices, the introduction of nanoscale Cu x S composites is now in high demand. This review focuses on the influence of the material morphology and dimensions on their performance in secondary batteries. The structures of Cu x S materials from zero-dimensional (0D) to 3D and their preparation are discussed. The primary purpose of this work is to provide an overview of the unique electrochemical and physical properties of particular structure and dimensionality which can promote these materials' application in the energy storage field. Along with this, this work summarizes the information on various synthesis strategies and how they can manage the morphologies of Cu x S micro-/nanocomposites. In the current fast technologically advancing society, the development of the most economically profitable and efficient synthesis routes is especially encouraged and required, and this aspect is also commented on in this review.

“…The cathodic peaks around 2.1 and 1.6 V (vs Li + /Li) are due to the two‐step reaction as shown below: CuS + Li → 1/2 Cu 2 S + 1/2 Li 2 S and 1/2 Cu 2 S + Li ↔ Cu + 1/2 Li 2 S . In the first charge process, a broad weak peak around 0.8 V corresponds to the decomposition of SEI layer, while two prominent peaks at 1.9 and 2.3 V are related to Li‐ion extraction . Therefore, it can be speculated from above analyses that the lithium‐storage performances of CuS( x wt%)@Cu‐BTC are affected by various factors such as porosity, conductivity, as well as the content and size of CuS.…”

“…However, the effective design of such materials is still a big challenge . Recently, MOFs have been considered as ideal precursors/sacrificial templates for preparing various ordered nanostructures such as porous carbon, M/C, MO x , MO x /MO x , carbon/MO x , MS x , and MO x /MS x . Among them, MOF‐derived MS x products usually possess high surface areas for energy conversion reaction, which has opened up a new research direction.…”

The CuS(x wt%)@Cu‐BTC (BTC = 1,3,5‐benzenetricarboxylate; x = 3, 10, 33, 58, 70, 99.9) materials are synthesized by a facile sulfidation reaction. The composites are composed of octahedral Cu3(BTC)2·(H2O)3 (Cu‐BTC) with a large specific surface area and CuS with a high conductivity. The as‐prepared CuS@Cu‐BTC products are first applied as the anodes of lithium‐ion batteries (LIBs). The synergistic effect between Cu‐BTC and CuS components can not only accommodate the volume change and stress relaxation of electrodes but also facilitate the fast transport of Li ions. Thus, it can greatly suppress the transformation process from Li2S to polysulfides by improving the reversibility of the conversion reaction. Benefiting from the unique structural features, the optimal CuS(70 wt%)@Cu‐BTC sample exhibits a remarkably improved electrochemical performance, showing an over‐theoretical capacity up to 1609 mAh g−1 after 200 cycles (100 mA g−1) with an excellent rate‐capability of ≈490 mAh g−1 at 1000 mA g−1. The outstanding LIB properties indicate that the CuS(70 wt%)@Cu‐BTC sample is a highly desirable electrode material candidate for high‐performance LIBs.

“…Based on the analysis of the above XRD and XPS results, it can be concluded that CuS without any impurities is affirmed. It was reported that a reversible Li + -intercalation/deintercalation process takes place at higher voltages (above approximately 1 V versus Li/Li + ) [29] through a number of intermediate phases with varying Li content. To continue the cycling series, CV and charge/discharge curves were tested in the potential range between 1 V to 3 V in this work.…”

CuS is a metal sulfide anode material used in constructing lithium ion batteries (LIBs) with great promise. However, its practical application is limited by rapid capacity decline, poor cycling, and rate performance. In this work, the CuS nanowire-on-nanoplate network is synthesized through an improved dealloying method under two contrasting reaction temperatures. When used as an LIB anode, the as-obtained CuS network exhibits superior cycling performance (420 mAh•g −1 retained after 100 cycles at 0.2 C). When at 3 C, it still delivers a capacity of around 350 mAh•g −1. The improved electrochemical performances of the CuS anode should be attributed to the well-designed nanowire-on-nanoplate network structure in which the introduction of nanowires improves Li storage sites, shortens Li-ion diffusion distance, enhances the conductivity of active materials, and offers multiscale spaces for buffering the volume variation. The fabrication route adopted in this paper has an important significance for developing the dealloying technique and designing more suitable anode structures for LIBs.
