Segmental Dynamics, Ion-Associated Relaxation, and Ion Transport in Cellulose-Based Gel Polymer Electrolytes Revealed by Broadband Dielectric Spectroscopy
: Cellulose-based gel polymer electrolytes (GPEs) are promising sustainable candidates for next-generation lithium batteries; however, the relationship between polymer dynamics and ion transport remains insufficiently understood. In this study, cellulose-based GPEs with varying lithium salt concentrations and crosslink...
