Study on NiSb2 as a New Lithium- Ions Batteries Anode Material

Keywords： lithium- ion secondary batteries , anode material , NiSb2 , intermetallic compounds

采用悬浮熔炼方法合成了新型锂离子电池负极材料NiSb2,并研究了其电化学性能.研究发现,退火与非退火NiSb2的首次可逆容量分别为494mAhg-1和430mAhg-1.经过15个循环后,非退火的NiSb2的放电容量仍保持在260mAhg-1,而退火的只剩下160mAhg-1.由于NiSb2具有优异的电化学性能,它可成为一种新型的锂离子电池负极材料.

To obtain a new anode material for lithium- ion battery, electrochemical properties on NiSb2 intermetallic compound synthesized by levitation melting were investigated. It is found that the reversible capacities of unannealed and annealed NiSb2 electrodes are about 494 mAhg- 1 and 430 mAhg- 1, respectively, at the first cycle. The discharge capacity of the unannealed NiSb2 electrode is still maintained at 260 mAhg- 1 even after 15 charge- discharge cyclies, while the annealed one was less than 160 mAhg- 1. Since NiSb2 exhibits a superior property, it would be a promising anode material for lithium- ion secondary batteries.
