Abstract:Porous Cu was fabricated by electrodepositing using hydrogen bubbles as the dynamic template,and subsequently treated by annealing to increase the structural stability.The 3-dimensional porous Cu6Sn5 alloy electrode was prepared by electrodepositing using the porous Cu as the substrate.The lithiation/delithiation potentials of 3-dimensional porous Cu6Sn5 were investigated by cyclic voltammetry.The initial lithiation process of 3-dimensional porous Cu6Sn5 alloy electrode at different temperature was studied ...
Keywords:Lithium-ion battery  Anode  3-Dimensional porous Cu6Sn5 alloy electrode  Electrochemical impedance spectroscopy
