Outline of Final Research Achievements |
A series of polymer electrolytes were synthesized. The lithium ion conductive nanofiber framework (NfF) and their composite membranes were fabricated. The NfF prevented crystallization of matrix electrolytes and showed good ion conductivity and high lithium ion transference numbers. The positive effect of NfF on the ion conductive characteristics were analyzed by FT-IT, Raman spectroscopy, and solid-state NMR measurements. The all-solid-state battery using the NfF composite membranes showed stable charge-discharge cycles and long-term cycle stability, indicating the effectiveness of the NfFs and importance of the control of phase interface .
