abstract = {The interface between ceramic particles and a polymer
matrix in a hybrid electrolyte is studied with high spatial
resolution by means of Electrochemical Strain Microscopy
(ESM), an Atomic Force Microscope (AFM)-based technique. The
electrolyte consists of polyethylene oxide with lithium
bis(trifluoromethanesulfonyl)imide (PEO6–LiTFSI) and
Li6.5La3Zr1.5Ta0.5O12 (LLZO:Ta). The individual components
are differentiated by their respective contact resonance,
ESM amplitude and friction signals. The ESM signal shows
increased amplitudes and higher contact resonance
frequencies on the ceramic particles, while lower amplitudes
and lower contact resonance frequencies are present on the
bulk polymer phase. The amplitude distribution of the hybrid
electrolyte shows a broader distribution in comparison to
pure PEO6–LiTFSI. In the direct vicinity of the particles,
an interfacial area with enhanced amplitude signals is
found. These results are an important contribution to
elucidate the influence of the ceramic–polymer interaction
on the conductivity of hybrid electrolytes.},
