Abstract: Co-Sn solid-solution nanoparticles with Sn crystal structure and tuned metal ratios were synthesized by a facile one pot solution-based procedure involving the initial reduction of a Sn precursor followed by incorporation of Co within the Sn lattice. These nanoparticles were used as anode materials for Li-ion batteries. Among the different compositions tested, Co Sn and Co Sn electrodes provided the highest capacities with values above 1500 mAh g at a current density of 0. 2 A g after 220 cycles, and up to 800 mAh g at 1. 0 A g after 400 cycles. Up to 81 % pseudocapacitance contribution was measured for these electrodes at a sweep rate of 1. 0 mV s , thereby indicating fast kinetics and long durability. The excellent performance of Co-Sn nanoparticle alloy-based electrodes was attributed to both the small size of the crystal domains and their suitable composition, which buffered volume changes of Sn and contributed to a suitable electrode restructuration.
