Abstract
Solid state electrolyte system-based polyethylene oxide (PEO) been widely used as one of the promising polymer host that mainly used in advance material such as secondary battery. They have many benefits of PEO such as good electrochemical stability, excellent compatibility with inorganic salts, reasonable fabrication cost, good safety, and good energy density. However, due to the semicrystalline behaviour this electrolyte system poor mechanical strength and thermo-stability limit its application in solid polymer electrolyte (SPE). Worldwide research has been conducted to enhance the mechanical strength and electrochemical properties of the PEO electrolyte system such as blending, inorganic filler and plasticizer etc. Therefore, in this review the topic has been narrow down on issues of PEO polymer electrolytes system.
