However, many parameters could influence the performance of the batteries, which depend on the processing of the electrode materials leading to different surface properties, sizes or crystalline phases. In this work a comparative study of tin and titanium oxide nanoparticles synthesized by different methods, undoped or Li doped, used as single components or in mixed ratio, or alternatively forming a composite with graphene oxide have been tested demonstrating an enhancement in capacity with Li doping and better cyclability for mixed phases and composite anodes.engAtribución 3.0 Españajournal articlehttp://dx.doi.org/10.1038/s41598-020-62505-xhttps://www.nature.com/open access538.9Ultrafine SnO_2 nanoparticlesLithium intercalationAmorphous TiO_2Anode materialCapacitygrapheneNanostructuresCompositeFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
