of their chemical stability, low inammability, negligible vapour pressure,
high ionic conductivity and wide electrochemical window. It has been dem-
onstrated that ILs can radically improve the performance, cyclability and
long-term stability of the electrochemical energy devices. Also, the durability
of such devices with IL electrolytes is reported to be signicantly better than
those of traditional organic and aqueous electrolytes.
Two main strategies have been pursued so far with a view to translate the
benets of ILs to polymer electrolytes. The rst strategy involves the design ...
