Electrodeposited Ni-Sn intermetallic alloy electrode for 3D sulfur battery. (2017) - Tolegen, B.
Abstract: 3D architecture appeared to be a promising design to enhance the performance of the Lithium-ion batteries by shortening the lithium ion diffusion path and increasing the energy density per unit area. In this paper, we report preliminary results of facile electrodeposition of intermetallic tin-nickel alloy from electrolyte solution onto 3D structured nickel foam for 3D lithium-sulfur battery. The coated films were characterized for their morphologies, structural and electrochemical properties. Scanning electron microscope images revealed thin and homogenous film while XRD revealed the expected phase of intermetallic alloy Ni3 Sn4 . The electrochemical activity of the film showed to be a promising start to be used as an anode material and needs further works to be optimized.
