Conductivity and dielectric properties of lithium-ion biopolymer blend electrolyte based film
In the present work, the effect of lithium salt contents on the ionic conduction of blend biopolymer electrolyte (BBE) comprising chitosan (CS) and methylcellulose (MC) complexed with lithium iodide (LiI) has been explored. The maximum ionic conductivity (6.26 × 10−6 S/cm) was achieved at room tempe...
