Characterization of corn starch-based solid polymer electrolyte with graphene oxide for sodium ion batteries / Syakirah Shahrudin

In this work, Corn Starch (CS) was used as the principle host to prepare CS-Sodium salt using solution casting technique. The film of CS-NaI electrolyte with ratio 75:25 yielded highest conductivity which is (1.43 ± 0.12)×10-04Scm-1. The increase in conductivity is also attributed to the increase in...
