Research Progress on Antimony-Based Anodes for Lithium-Ion Batteries
Antimony(Sb),due to its unique puckered layer structure,exhibits outstanding electrical conductivity and reactivity in lithium-ion storage.Additionally,it provides a high theoretical capacity of up to 660 mAh g-1 through the formation of Li3Sb alloy.Compared with graphite,Sb not only has a higher theoretical capacity but also possesses a safer reaction potential.Its reaction process is simpler and accompanied by smaller volume changes compared to silicon(Si),germanium(Ge),and tin(Sn).This review article delves into the latest research progress on antimony-based electrode materials,covering their storage mechanisms and application achievements in lithium-ion batteries.At the same time,facing the challenges and prospects of further enhancing the applicative performance of antimony-based electrode materials,this paper also proposes corresponding discussions and outlooks.
