abstract = {All-solid-state sodium batteries (Na-ASSBs) are regarded as
an ecologic and economical alternative to their Li congeners
for stationary applications. Ceramic-based Na-ASSBs benefit
from the high conductivity of the oxide Na-ion conductors
used as electrolyte, as well as from their good mechanical,
chemical and thermodynamic stability. However, so far
Na-ASSBs suffer from severe contact problems in the positive
electrodes and subsequently unsatisfactory cell performance.
In this report, the inter-ceramic contact problems are
solved by combining the infiltration of a porous electrolyte
scaffold by precursor solution with in situ synthesis of
electrode active material (chemical infiltration) to
fabricate model cells using Na3V2P3O12 (NVP),
Na3.4Zr2Si2.4P0.6O12 (NZSP) and Na as the positive
electrode, electrolyte and negative electrode materials,
respectively. Optimized interface between NVP nano layer and
NZSP backbone was formed, providing effective ion transfer
and minimizing the stress caused by volume change of
electrode active material during charging and discharging
processes. The interface resulted in a highly stable battery
performance at 25 °C. The performances, achieved without
using any liquid or polymer phase as an accommodation
medium, suggest a promising future for chemical infiltration
as fabrication process for ceramic-based ASSBs.},
