A Review of Modified Cellulose for Electrochemical Energy Storage with a Multiphysics Framework for Quaternized Bagasse Nanocellulose/Al₂O₃–PEO Composite Electrolytes in Solid-State Batteries
Abstract: A critical review of modified cellulose for electrochemical energy storage is integrated with a potassium-specific multiphysics framework using cellulose obtainable from India-relevant feedstocks, including sugarcane bagasse, cotton/cotton stalk, banana pseudostem, Hibiscus/kenaf-type biomass, and other agricultural residues. The framework addresses the coupled requirements of ambient-temperature ionic transport, K⁺ selectivity, and mechanical integrity in solid polymer electrolytes. A hierarchical QCNF@Al₂O₃/PEO₁₆–KTFSI₁ architecture is evaluated in which quaternized bagasse cellulose nanofibers provide percolated reinforcement …
