Overview

This research demonstrates improved ionic conductivity in 3D printable gel polymer electrolytes, suggesting advances in battery performance and design.

Key Points

  • This study aims to enhance gel polymer electrolytes for Li-ion batteries through 3D printing techniques.
  • Developed 3D printable gel polymer electrolytes using a UV-curable resin and liquid electrolyte.
  • Evaluated the impact of resin-to-electrolyte ratios on ionic conductivity and processability.
  • Characterized electrochemical stability through symmetric cell testing.
  • Identified optimal resin-to-electrolyte ratio of 1:4 v/v for high ionic conductivity.
  • Achieved ionic conductivities of 3.4 × 10 -3 S.cm -1 (DEC-based) and 3.1 × 10 -3 S.cm -1 (PC-based).
  • Demonstrated effective Li 0 plating/stripping over 100 cycles, maintaining stability up to ~4.5 V vs. Li 0 /Li +.
