Free Mesogen Assisted Assembly of the Star-shaped Liquid-crystalline Copolymer/Polyethylene Oxide Solid Electrolytes for Lithium Ion Batteries

- Solid electrolytes based on PEO/LiClO4 with star-shaped polymer and free liquid crystals as filler are prepared.
- Adding appropriate amount of small molecule fillers can provide a highly ordered nanoscale phase separation.
- The stacking defects of star copolymer can be repaired.
- Good chain mobility of PEO can be maintained.
- The electrochemical performance is greatly increased due to the efficient ions channel along amorphous PEO phase.
