High rate capability pure Sn-based nano-architectured electrode assembly for rechargeable lithium batteries
Résumé
Newhigh surface area nano-architectured copper current collectors have been designed based on simple
electrodeposition method. The nano-architectured electrode design not only increases the effective surface
area of the electrode but it is also very suitable for sustaining the mechanical and structural strain
during electrochemical reaction. In this work, a nano-architectured Sn anode for Li-ion battery, based on
Li–Sn alloying reaction, delivers very high cycle life and good power performance compared to planar tin
films. This electrode could be successfully used in the field of 3D microbatteries.
