abstract = {The fast Li+ transportation of “polymer-in-ceramic”
electrolytes is highly dependent on the long-range Li+
migration pathways, which are determined by the structure
and chemistry of the electrolytes. Besides, Li dendrite
growth may be promoted in the soft polymer region due to the
inhomogeneous electric field caused by the commonly low Li+
transference number of the polymer. Herein, a
single-ion-conducting polymer electrolyte is infiltrated
into intertwined Li1.3Al0.3Ti1.7(PO4)3 (LATP) nanofibers to
construct free-standing electrolyte membranes. The composite
electrolyte possesses a large electrochemical window
exceeding 5 V, a high ionic conductivity of 0.31 mS cm–1
at ambient temperature, and an extraordinary Li+
transference number of 0.94. The hybrid electrolyte in the
lithium symmetric cell shows stable Li plating/stripping up
to 2000 h under 0.1 mA cm–2 without dendrite formation.
The Li|hybrid electrolyte|LiFePO4 battery exhibits enhanced
rate capability up to 1 C and a stable cycling performance
with an initial discharge capacity of 131.8 mA h g–1 and a
retention capacity of 122.7 mA h g–1 after 500 cycles at
0.5 C at ambient temperature. The improved electrochemical
performance is attributed to the synergistic effects of the
LATP nanofibers and the single-ion-conducting polymer. The
fibrous fast ion conductors provide continuous ion transport
channels, and the polymer improves the interfacial contact
with the electrodes and helps to suppress the Li dendrites.},
