“…Other than carbon materials, there are other materials used to form composites with CuS and Cu 2 S, such as CuS@Mo 2 S microcubes (Figure 9e,f) [46] and Cu 2 S/MoO 3 nanocomposite. [51] These non-carbon-based nanocomposites also achieved high performance in LiÀ Cu x S cells. For example, CuS@Mo 2 S microcubes were tested under different rates from 500 to 4000 mA g À 1 , realizing a capacity of 920 mAh g À 1 after 200 cycles at 500 mA g À 1 .…”

CuS and Cu₂S as Cathode Materials for Lithium Batteries: A Review

2019

lithium-ion batteries (LIBs) take a very important role for energy storage. LIBs are dominant in consumer electronics, and they have also entered the market of hybrid electric vehicles (HEVs), plug-in HEVs, and pure EVs. However, state-ofthe-art LIBs are electrochemically intercalation-based and are still limited in energy density and power rates. To address these challenges and others (e. g. safety issues and cost), conversion-based copper sulfides (Cu x S, 1 � x � 2) have been investigated as alternative cathodes for improved electrochemical performance, that is, higher energy density, better cycling stability, and enhanced rate capability. In this work, we summarize the recent research progress on Cu x S to gain a better understanding of the material's electrochemical mechanisms and develop feasible strategies for improving its performance.

Gadolinium (Gd3+) substituted bismuth ferrite (BF) photocatalysts were synthesized using sol‐gel method and the effect of Gd3+ substitution was investigated on the structural, optical and surface properties of Gd3+ substituted BF nanoparticles. Different techniques such as X‐ray diffraction (XRD), high‐resolution transmission electron microscopy (HRTEM) with Selected area electron diffraction pattern (SAED), Fourier transform infrared spectra (FTIR), ultraviolet‐visible diffuse reflection spectra (UV‐DRS), field emission scanning electron microscopy (FESEM), Brunauer‐Emmett‐Teller (BET), and photoluminescence spectra (PL) were employed to characterize the nanoparticles. Compared to nascent BF, the Gd3+ substituted BF nanoparticles showed improved long‐range ordering, smaller pore diameter, higher porosity and redshift of the band gap. These properties were responsible for their improved photocatalytic activity, when tested for the photodegradation of organic dyes. It was found that 3 % Gd3+ substituted BF nanoparticles exhibited enhanced the photocatalytic activity of indigo carmine dye with a degradation ranging from 34 % to 69 %, while for Congo red dye the degradation varied from 37 % to 73 % under the visible light. Furthermore, bio‐sensing properties of BF materials were improved as detected by the uric acid using cyclic voltammogram technique.

“…Lithium ion batteries (LIBs) are anticipated as the promising electrical devices due to their high specific capacity, long lifetime, good stability and superior rate capabilities. [3][4][5][6] However, commercial LIB anodes are limited by their low theoretical capacity (371 mAh g À1 for graphite). Therefore, present research communities are intensively devoted towards exploring new anode materials for LIBs.…”

High energy demand has directed the present‐day research towards synthesis and applications of heterostructured nanomaterials such as molybdenum oxysalts over mono‐structured nanomaterials. Molybdenum oxysalt is a promising anode material for lithium ion batteries because of its high theoretical lithium storage capacity (998 mAh g−1) and flexible composition. Engineering the morphology and porosity of a material has proven to be a productive approach towards enhancing its performances. Here in, we have demonstrated a one pot synthesis of mesoporous MnMoO4 nanorods and its enhanced electrochemical performance for Li‐ion battery anode. Several physiochemical techniques have been used to validate the desired properties and purity of the synthesized material. It exhibits high lithiation capacity of 1050 mAh g−1 and stability over 100 cycles at 0.5 C. The enhanced performance is attributed to its structural stability and mesoporous nature.
