Abstract
This study explores the electrochemical performance of M/Sn/M (M: Ni and Cu) anodes in rechargeable lithium ion batteries. Sandwich electrode is proposed to improve the electrochemical performance of Sn anode. Herein the electrochemical performances of Cu/Sn/Cu and Ni/Sn/Ni films are compared to that of the pure Sn electrode. The galvanostatic test results prove that stress buffering action of M (M: Cu, Ni), differentiation in the surface reactivity of the electrode, improved the adhesion of the film. After 30 cycle, the capacities of the pure Sn, the Cu/Sn/Cu and the Ni/Sn/Ni films are 22mAh g-1, 140mAh g-1, 205 mAh g-1 respectively. It is demonstrated that the sandwich model improves cycle performance of the electrode.
