abstract = {Polymer electrolytes are attractive candidates to boost the
application of rechargeable lithium metal batteries.
Single-ion conducting polymers may reduce polarization and
lithium dendrite growth, though these materials could be
mechanically overly rigid, thus requiring ion mobilizers
such as organic solvents to foster transport of Li ions. An
inhomogeneous mobilizer distribution and occurrence of
preferential Li transport pathways eventually yield favored
spots for Li plating, thereby imposing additional mechanical
stress and even premature cell short circuits. In this work,
we explored ceramic-in-polymer hybrid electrolytes
consisting of polymer blends of single-ion conducting
polymer and PVdF-HFP, including EC/PC as swelling agents and
silane-functionalized LATP particles. The hybrid electrolyte
features an oxide-rich layer that notably stabilizes the
interphase toward Li metal, enabling single-side lithium
deposition for over 700 h at a current density of 0.1 mA
cm–2. The incorporated oxide particles significantly
reduce the natural solvent uptake from 140 to 38 wt $\%$
despite maintaining reasonably high ionic conductivities.
Its electrochemical performance was evaluated in
LiNi0.6Co0.2Mn0.2O2 (NMC622)||Li metal cells, exhibiting
impressive capacity retention over 300 cycles. Notably, very
thin LiNbO3 coating of the cathode material further boosts
the cycling stability, resulting in an overall capacity
retention of $78\%$ over more than 600 cycles, clearly
highlighting the potential of hybrid electrolyte concepts.},
