Abstract:	Polycrystalline samples of isostructural MSb 2O 4 (M = Co, Ni) have been prepared by solid state synthesis and lithium-storage is investigated as possible anode materials for lithium-ion batteries. The reaction mechanism of lithium with MSb 2O 4 (M = Co, Ni) is explored by galvanostatic cycling, cyclic voltammo-gram and ex situ studies. Both CoSb 2O 4 and NiSb 2O 4 exhibit similar electrochemical behavior and show reversible capacity of 490 and 412 mAhg -1 respectively in the first cycle. Reversible alloying de-alloying of Li x Sb takes place in an amorphous matrix of M (Co, Ni) and Li 2O during electrochemical cycling. © 2012 Elsevier Ltd. All rights reserved.
