Antimony Oxides‐Based Anode Materials for Alkali Metal‐Ion Storage

Abstract

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.

Recent advances in rational design for high-performance potassium-ion batteries

“…528–537 Metal oxides, metal sulfides, metal selenides, and metal phosphides are the most representative conversion-type anode materials. 351,355,389,400,538–543 It should be noted that some of the energy storage contributions of sulfides ( e.g. , MoS 2 and ReS 2 ) and selenides ( e.g.…”

Covalent Organic Frameworks as Electrode Materials for Alkali Metal‐ion Batteries

“…[13,19] Researchers have found that the performance of electrode materials is a key factor affecting the improvement of battery performance in a large number of explorations. [20] Most of the traditional electrode materials are inorganic compounds, pure carbon materials and derivatives, such as metal phosphates, metal oxides [21][22][23] and graphite et al The larger radius of Na + , K + makes the resistance in the process of insertion/extraction in the host material significantly larger than that of Li + , which is the main reason for the generally lower specific capacity of the reported electrode materials for SIBs/PIBs. And in the cycling process, the volume change of the electrode materials for SIBs/PIBs is larger compared with that of LIBs, and the internal structure of the electrodes is more likely to be damaged, resulting in low cycling performance of battery.…”

Uniformly anchoring Sb2O5 nanoparticles on graphene sheets via Co2+-induced deposition for enhanced lithium/sodium-ion storage

“…1,2 Among these, antimony oxides (Sb x O y ) hold great competitive edges as alternative electrode materials for lithium-/sodium-ion batteries (LIBs/SIBs) on account of their high theoretical specific capacities (>1000 mA h g −1 ) according to the reversible conversion–alloying mechanism. 3–8 However, Sb x O y -based electrodes still suffer from inherent poor conductivity and structure collapse during repeated lithium/sodium-storage processes, causing unsatisfactory rate capability and severe capacity fading during cycling, which has delayed their practical application.…”
