The rapid development of human society has resulted in increased energy demand; lithium ion batteries (LIBs) and sodium ion batteries (SIBs) are promising alternatives to traditional fossil fuels to meet these energy requirements.
Recently, antimony (Sb)-based intermetallic compounds have attracted considerable research interests as new candidate anode materials for high-performance lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to their high theoretical capacity and suitable operating voltage.
In this study, the recent progress of Sb-based materials including elemental Sb nano-structures, intermetallic Sb alloys and Sb chalcogenides for lithium-ion and sodium-ion batteries are introduced in detail along with their electrode mechanisms, synthesis, design strategies and electrochemical performance.
E-mail: [email protected] Antimony (Sb) shows high conductivity and reactivity not only with lithium ions, but also with sodium ions due to its unique puckered layer structure; also, it can deliver a high theoretical capacity of 660 mA h g −1 by forming Li 3 Sb or Na 3 Sb.
During the course of experiments with Li 4 Ti 5 O 12 /Sb composite anodes, we have found a new class of electroactive materials namely, the family of lithium antimonites (LiSbO 3 and LiSb 3 O 8) which show encouraging results as lithium-ion battery anode with respect to a low intercalation potential and high discharge capacity.
However, the barrier to widespread adoption of batteries is their high cost. Here we describe a lithium–antimony–lead liquid metal battery that potentially meets the performance specifications for stationary energy storage applications.
Research which focused on DFT studies also showed the potential of monolayer Sb for LIB anodes in rechargeable batteries, which could provide relatively strong Li adsorption. In conclusion, antimony is a rare element on the planet, but it offers intriguing features when it comes to the needs of energy storage systems.
