摘要: A liquid-like poly (ionic liquid)(PIL) with a very low glass transition temperature of− 51° C and a thermal decomposition temperature of 202.7° C was synthesized. A PIL-based electrolyte by mixing this poly (ionic liquid) with additives of 10 wt% propylene carbonate and 0.1 M LiClO4 is proved to be an excellent electrolyte for lithium-ion battery. The obtained PIL-based electrolyte exhibits a high ionic conductivity of 8.3× 10–5 S cm–1 at 25° C and 2.0× 10–4 S cm–1 at 60° C and a wide electrochemical potential window up to 5.61 V …
