abstract = {Solid-state batteries (SSBs) with metallic lithium (Li)
anodes and nonflammable solid-state electrolytes (SSEs) are
viewed as the next-generation batteries because of their
potential improvement in energy density and guarantee of
safety. However, even though the high-density solid garnet
SSE pellets exhibit high ionic conductivity, high
transference number, and large shear modulus, the
unexpectedly serious occurrence of dendrite propagation
remains a problem. Herein, a mixed conductive layer (MCL)
consisting of electron-conductive nanoparticles embedded in
an ion-conductive network is introduced at the interface
between the garnet SSE and the Li anode. Such MCL not only
leads to the transition from lithiophobicity to
lithiophilicity, but also homogenizes the electric-field
distribution inside the MCL and relieves the electronic
attacks to the garnet. As a result, the Li/MCL/garnet/MCL/Li
cells show a critical current density as high as 1.2 mA
cm−2 and stable cycling for over 1000 h at 0.1 mA cm−2.
The LiCoO2/Li cells with the MCL-protected interface show
excellent cycling and rate performance at room temperature.
These results demonstrate a rational design for a stable
garnet/Li interface and an effective strategy to enable Li
metal anodes in SSBs.},
