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. eng Influence of doping and controlled sn charge state on the properties and performance of SnO nanoparticles as anodes in li-ion batteries journal article URL https://docta.ucm.es/bitstreams/95319f61-9844-4859-884b-142c024dc36e/download File MD5 2f30b61b6d0bf12d505df8544dbaa5d0 3818407 application/pdf MaestreD 11 Postprint+EMB 27-ago-2021 (1).pdf URL https://docta.ucm.es/bitstreams/a3aec4d9-aed3-40ad-bd6e-dddcd1422b54/download File MD5 fab97e463567f0e1d04198f874f83666 80772 text/plain MaestreD 11 Postprint+EMB 27-ago-2021 (1).pdf.txt
