Studies on Preparation and Properties of Novel Gel Polymer Electrolyte

Abstract:

Article Preview

The cheaper plant materials such as wheat straws and corn stalks, which contain a lot of celluloses, were used to synthesize the new GPE by graft copolymerization with acrylic acid (AA). A kind of thinner film was prepared by coating the mixture of above precursor with polyvinyl alcohol (PVA). The new polymer film was expected to have larger uptake of standard liquid electrolyte. Therefore, its ionic conductivity could reach to 6.7×10-3 S•cm-1, which was near to the conductivity of liquid electrolyte (~10-3 S•cm-1). So the lithium batteries containing the new GPE could have better charge-discharging efficiency with larger current density. The new GPE was also expected to be degradable as it was made of plant stem materials.
