Herein, the preparation of an innovative crosslinked polymer electrolyte (PEO_HPyr) encompassing protic ionic liquids (PILs) displaying high ionic conductivity, wide thermal, and electrochemical stability is reported, thus suitable for use in safe energy storage devices. The first example of an all‐solid‐state electrochemical double layer capacitor (EDLC) containing a PEO_HPyr‐based electrolyte is presented, which shows high performance at ambient temperature and exceptional stability. Furthermore, the first example of a PIL‐based lab‐scale lithium‐metal cell with lithium iron phosphate cathodes is also presented, which provides almost full capacity (i.e., 150 mAh g⁻¹ at C/20) and highly reversible cycling at ambient conditions and different current rates. The excellent results obtained clearly demonstrate that PIL‐based crosslinked polymer electrolytes represent a new and very interesting class of solid electrolytes for energy storage devices.
