“…The peak at 0.28 V is ascribed to multiple alloying reactions [64]. In the anodic scan, two peaks at 0.80 V and 1.61 V correspond to the dealloying of Na 3 Sb to Sb, and the recovery of SbO 2 , respectively [65]. After the first cycle, the curves almost coincide, indicating the satisfactory cyclic stability of the Sb/SbO 2 @rGO-10 electrode [66].…”

Antimony (Sb) and its oxides, as promising electrode materials, have attracted much attention because of their low cost, environmental friendliness, and high theoretical capacity. Herein, boron doped flower-cluster-like Sb/SbO2@reduced graphene oxide (rGO) composites are synthesized for use as sodium-ion battery anode materials using a solvothermal strategy. The contents of Sb and antimony oxide (SbO2) are controlled by adding different contents of NaBH4. Meanwhile, the introduction of NaBH4 successfully realizes boron doping and enlarges the lattice spacing of the SbO2, improving its conductivity and Na+ transport. As a result, optimal Sb/SbO2@rGO-10 composites display a desirable capacity of 346 mAh g−1 at 50 mA g−1 after 100 cycles with a capacity retention of 106%. Even at high current densities, a capacity of 236 mAh g−1 is achieved, demonstrating a satisfactory rate capacity. Moreover, the Sb/SbO2@rGO-10 electrode shows satisfactory Na storage performance at low temperatures. In addition, sodium-ion full cells are assembled using an Sb/SbO2@rGO-10 anode and a Na3V2(PO4)2O2F cathode, with which a satisfactory electrochemical performance of 102 mAh g−1 after 50 cycles at 50 mA g−1 is achieved, showing their high practical potential.

“…Coating with carbon layer or conductive polymers can also improve electrochemical alkali metal‐ion storage performance [7a,9b,23c,d,36] . Hu and his colleagues obtained nano‐thin carbon‐encapsulated Sb 6 O 13 mesoporous nanocomposite by coating Sb 6 O 13 with a thin layer of carbon nanoparticles [9b] . The inner mesopores can accommodate volume expansion during cycling, as well as the carbon coating layer maintains structural integrity and electrical contact, leading to excellent rate performance and cycling stability for sodium‐ion storage.…”

With the increasing demand for renewable energy, alkali metal-ion (lithium/sodium/potassium-ion) batteries play more and more important roles in the field of static storage and electrical vehicle industry. Novel anode materials with high reversible capacity, safety and long-term cycling stability are desiderated to meet the ever-growing demand for alkali metal-ion batteries with high electrochemical performance. Antimony oxides (Sb x O y ) show electrochemical reaction activity with all of lithium, sodium and potassium, and are expected to be promising anode materials for alkali metal-ion storage due to their high theoretical capacities, appropriate operating potential and excellent safety properties. This review is devoted to overview the research progress on reaction mechanism and improvements in electrochemical performance of antimony oxides for alkali metal-ion storage, and look forward to their further prospects.

“…The in situ growth techniques result in uniform distribution of NPs on the NC, due to a controlled growth process. A variety of the growth methods, such as chemical reduction, sol-gel, hydrothermal, thermal, physical or chemical vapour deposition methods, electrochemical reduction or deposition methods etc are categorized under the in situ crystallization process [46][47][48][49]. In addition, the in situ crystallization or growth of NPs on NCs and their derivatives is further categorized as a chemical route or a physical route based on the process involved and the precursors used.…”

As renewable energy is becoming a critical energy source to meet the global demand, electrochemical energy storage devices become indispensable for the efficient energy storage and reliable supply. The electrode material is the key factor determining the energy storage capacity and the power delivery of the devices. Carbon-based materials, specifically graphite, activated carbons etc., are extensively used as for electrodes, yet their low energy densities impede the development of advanced energy storage materials. Decoration by nanoparticles of metals, metal oxides, nitrides, carbides, phosphides, chalcogenides, and bimetallic components is one of the most promising and easy-to-implement strategies to significantly enhance the structural and electronic properties, pore refinement, charge-storage, and charge-transfer kinetics of both pristine and doped carbon structures, thereby making their performance promising for next-generation energy storage devices. Structuring the materials at nanoscale is another probable route for better rate performance and charge-transfer kinetics. This review covers the state-of-art nanoparticle decorated nanocarbons as materials for battery anode, metal-ion capacitor anode, and supercapacitor electrode. A critical analysis of the elemental composition, structure, associated physico-chemical properties and performance relationships of nanoparticle-decorated nanocarbon electrodes is provided as well to inform the future development of the next generation of advanced energy storage materials and devices.
