Highly conductive nonstoichiometric protic poly(ionic liquid) electrolytes
Nonstoichiometric protic ionic liquids have recently gained interest because proton acceptors are crucial in the electrolyte of many electrochemical applications such as fuel cells, proton batteries and supercapacitors. In the present work we have prepared and studied several protic poly(ionic liquid)s doped with acid in nonstoichiometric amounts. The poly(ionic liquid)s were based on polydimethyl
