锂离子电池锡镍合金负极材料的性能研究
The properties study of Sn/Ni alloy as anode materials for Li-ion batteries
摘要
Abstract
An ab initio method with the first-principles plane-wave pseudopotentials based on the density functional theory has been used to calculate the physical character and electrochemical performance of various alloy phases in Sn-Ni alloy. The result shows that Ni_3Sn_2 alloy phase has stable electrochemical voltage. But Ni_3Sn_4 alloy phase has fluctuation electrochemical voltage compared with other phases. Meanwhile, a series of Ni-Sn alloys prepared by electrodeposition, and the performances of the alloys as the anode for lithium ion battery were tested with charge and discharge equipment. The result shows that Ni_3Sn_4 alloy phase has optimized electrochemical performance, and is the best structural materials for lithium ion battery.关键词
