abstract = {Solid-state batteries (SSBs) with alkali metal anodes hold
great promise as energetically dense andsafe alternatives to
conventional Li-ion cells. Whilst, in principle, SSBs have
the additionaladvantage of offering virtually unlimited
plating current densities, fast charges have so far onlybeen
achieved through sophisticated interface engineering
strategies. With a combination ofsurface sensitive analysis,
we reveal that such sophisticated engineering is not
necessary inNaSICON solid electrolytes
(Na3.4Zr2Si2.4P0.6O12) since optimised performances can be
achievedby simple thermal treatments that allow the
thermodynamic stabilization of a nanometric Na3PO4protective
surface layer. The optimized surface chemistry leads to
stabilized Na|NZSP interfaceswith exceptionally low
interface resistances (down to 0.1 Ωcm2 at room
temperature) and hightolerance to large plating current
densities (up to 10 mA cm−2) even for extended cycling
periodsof 30 min (corresponding to an areal capacity 5 mAh
cm−2). The created Na|NZSP interfaces showgreat stability
with increment of only up to 5 Ωcm2 after four months of
cell assembly.},
