Ionic conductivity of fabricated carboxymethyl cellulose solid polymer electrolyte with ammonium nitrate / Najah Amani Ahmad Jamri

Solid polymer electrolyte (SPE) has been established as an alternative for liquid electrolyte because it is safer, more stable, and easier to use. SPE consist of inorganic salt and polymer host. Carboxymethyl cellulose (CMC) is suitable as biobased polymer host for bio-based SPE because it is low-co...
