      abstract     = {Freestanding electrodes are a promising way to increase the
                      energy density of the batteries by decreasing the overall
                      amount of electrochemically inactive materials. Freestanding
                      antimony doped tin oxide (ATO)-based hybrid materials have
                      not been reported so far, although this material has
                      demonstrated excellent performance in conventionally
                      designed electrodes. Two different strategies, namely
                      electrospinning and freeze-casting, are explored for the
                      fabrication of ATO-based hybrid materials. It is shown that
                      the electrospinning of ATO/carbon based electrodes from
                      polyvinyl pyrrolidone polymer (PVP) solutions was not
                      successful, as the resulting electrode material suffers from
                      rapid degradation. However, freestanding reduced graphene
                      oxide (rGO) containing ATO/C/rGO nanocomposites prepared via
                      a freeze-casting route demonstrates an impressive rate and
                      cycling performance reaching 697 mAh g−1 at a high current
                      density of 4 A g−1, which is 40 times higher as compared
                      to SnO2/rGO and also exceeds the freestanding SnO2-based
                      composites reported so far. Antimony doping of the nanosized
                      tin oxide phase and carbon coating are thereby shown to be
                      essential factors for appealing electrochemical performance.
                      Finally, the freestanding ATO/C/rGO anodes are combined with
                      freestanding LiFe0.2Mn0.8PO4/rGO cathodes to obtain a full
                      freestanding cell operating without metal current collector
                      foils showing nonetheless an excellent cycling stability.},
