英文摘要	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 by electrochemical impedance spectroscopy. The results indicate that the Nyquist plots are composed of three regions in the main lithiation range: high frequency arc represents solid electrolyte interphase(SEI) impedance, middle frequency arc represents charge transfer impedance, and low frequency arc represents phase transformation impedance. The variation of the electrochemical impedance versus temperature was analyzed by simulating the experimental data using appropriate equivalent circuit.
