RT Journal Article T1 Influence of doping and controlled sn charge state on the properties and performance of SnO nanoparticles as anodes in li-ion batteries A1 Vázquez López, Antonio A1 Maestre Varea, David A1 Ramírez Castellanos, Julio A1 González Calbet, José María A1 Pís, Igor A1 Nappini, Silvia A1 Yuca, Neslihan A1 Cremades Rodríguez, Ana Isabel AB Li-ion batteries (LiB) play nowadays a major role in several technological fields. In addition to enhanced high capacity and long cyclability, some other issues regarding safety, materials sustainability, and low cost remain unsolved. Tin oxide (SnO_2) presents several of those advantages as an anode material; however, some aspects still require to be investigated such as capacity fading over cycles. Herein, tin oxide nanoparticle-based anodes have been tested, showing high capacities and a significant cyclability over more than 150 cycles. A complementary strategy introducing doping elements such as Li and Ni during the synthesis by hydrolysis has been also evaluated versus the use of undoped materials, in order to assess the dependence on SnO_2 quality and properties of battery performance. Diverse aspects such as the Sn charge state in the synthesized nanoparticles, the variable incorporation of dopants, and the structure of defects have been considered in the understanding of the obtained capacity.
