## Title

- title: Surface-modified BaTiO<sub>3</sub> as a functional filler in poly(ethylene
    oxide)-based solid polymer electrolytes for lithium-metal batteries

## Description

- description: Poly(ethylene oxide) (PEO)-based polymer electrolyte is regarded as
    a promising candidate for solid-state lithium metal batteries due to its unique
    lithium conduction mechanism compared to inorganic solid-state electrolyte. However,
    the development of this electrolyte is hindered by its low ionic conductivity
    and poor mechanical strength. In this study, we enhance the mechanical stability
    and ionic conductivity of PEO-based polymer electrolyte by incorporating barium
    titanate nanoparticles coated with 3-(triethoxysilyl) propionitrile (BTO@TESPN)
    as solid fillers. With 10 wt% of BTO@TESPN, ionic conductivity and critical current
    density at 60 C is improved to 5.67  10-4 S cm-2 and 1.6 mA cm-2, respectively,
    compared to 2.69  10-4 S cm-2 and 1.0 mA cm-2 without the filler. Furthermore,
    the symmetric cell with Li utilizing this electrolyte demonstrates stable cycling
    at a rate of 0.1 mA cm-2 for a minimum duration of 1000 h. Additionally, the lithium
    iron phosphate (LiFePO4)-Li battery exhibits excellent stability up to 700 cycles
    at 60 C at a current rate of 0.5 C while maintaining a capacity retention of
    up to 93.0%. This research presents an innovative approach towards enhancing PEO-based
    solid polymer electrolytes, by regulating the interface between the filler and
    the polymer matrix.
