Improvement of electrical properties of CMC-PVA doped with various contents of LiNO3 as an application for hybrid polymer electrolytes

The present work was carried out with the development of hybrid polymer electrolytes (HPEs) by using carboxymethyl cellulose (CMC)–polyvinyl alcohol (PVA) doped with different contents of lithium nitrate (LiNO3) for the determination of their structural and conduction properties. The structural anal...
