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.},
