To obtain a new anode material for lit hium-ion battery,electrochemical properties on NiSb 2 intermetallic compound synthesized by levitation melting w ere investigated.It is found that th e reversible capacities of unannealed and annealed NiSb 2 electrodes are about 494mAhg -1 and 430mAhg -1 ,respectively,at the first cycle.T he discharge capacity of the unannealed NiSb 2 electrode is still maintained at 260mAhg -1 even after 15charge-discharge cyclies,while the annealed one was less t han 160mAhg -1 .Since NiSb 2 exhibits a superior property,it wou ld be a promising anode material for l ithium -ion secondary batteries.
