Polymer materials in combination with suitable metal salts give electrolytes for advanced high energy electrochemical devices, e.g. batteries/fuel cells, electrochemical display devices/smart windows and photoelectrochemical cells, etc. [1, 2, 3, 4, 5]. The main advantages of polymeric electrolytes are satisfactory mechanical properties, ease of fabrication as thin films and an ability to form good electrode/electrolyte contact. Most of the studies in this field are devoted to poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) based polymer electrolytes using alkali metal salts [6, 7, 8, 9, 10, 11]. Some conducting polymer electrolytes have been reported based on PEO complexed with ammonium salts such as NH4SCN and NH4CF3SO3 , NH4ClO4 [13, 14] and NH4I .
In an attempt to study the possibility of fabricating electrochemical cells based on polymers other than widely studied polymers such as PEO, PPO, etc., studies have been undertaken on electrochemical cells based on...
