Abstract:

Complexes formed between certain polyethers and alkali metal salts have received considerable attention as solid electrolytes for high energy density battery applications. Polypropylene oxide PPO is known to form amorphous and single-phase complexes with a variety of lithium and sodium salts. Previous nuclear magnetic resonance studies of PPO-NaI samples have demonstrated the presence of enhanced Na mobility in the temperature region just above the glass transition temperature, Tg. This observation is consistent with the accumulated experimental and theoretical evidence that the ion transport process is highly dependent on polymer segmental mobility. Solid electrolytes, Polyethers.
