Abstract:<\/h4>\n
High-capacity materials are required in order to address the environmental concerns of our modern society, ultimately leading to safe and eco-friendly high-energy batteries. Silicon-nanowire anodes (SiNWs) have the potential to significantly increase the energy density of lithium-ion batteries (LIBs). In order to improve the mechanical durability and the electrochemical performance of SiNW-anodes, we fabricated a silicon-nickel (SiNi) composite anode by electroless deposition of nickel, followed by annealing at high temperature to obtain nickel silicides of different content and composition. The morphology of SiNi-alloy anodes was examined by SEM, in situ<\/i> TEM and EDS methods in order to understand how different deposition protocols affect the coating of the silicon nanowires. The formation of Ni-silicides was found to occur during thermal treatment at 900 \u00b0C. Despite the incomplete shell coverage of SiNWs composed of multiple phases and grains, the electrochemical performance of binder-free and conducting-additive-free SiNi-alloy anodes showed stable electrochemical behavior and higher capacity retention compared to the pristine SiNW anode. Li\/SiNW-SiNi x<\/i><\/sub> cells ran at C\/2 rate for 200 reversible cycles, exhibiting 0.1%\/cycle capacity loss after completion of the SEI formation.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1039\/d1ra04703e Authors: Edna Mados, Nimrod Harpak, George L\u00e9vi, Fernando Patolsky, E.
