Over a year, the electrochemical power was obtained using liquid electrolyte due to its high ionic conductivity. Yet, this liquid electrolyte gave rise to problems such as leakage, reaction with electrode, and poor electrochemical stability, which causes it to
be unsuitable for the use in electrochemical devices. When the first reported solid polymer electrolyte was made in 1973, the researcher realized that this polymer electrolyte can be used to replace the liquid electrolyte due to its excellent mechanical and thermal stability and high ionic conductivity [1,2]. Solid polymer
electrolytes are the key material of all-solid-state energy devices and have been extensively studied in the fields of materials science,polymer science and electrochemistry [3–5]. Within the realm of solid polymer electrolytes, proton conducting solid polymer electrolytes(PCSPEs) has become materials of growing interest because of their wide raging applications in electrochemical devices such as
solid-state batteries.
