Electrochemical Capacitance of CNF-Ti₃C₂T_x MXene-Based Composite Cryogels in Different Electrolyte Solutions for an Eco-Friendly Supercapacitor.

ABSTRACT: Cellulose nanofibrils (CNFs) are promising materials for flexible and green supercapacitor electrodes, while Ti₃C₂T_x MXene exhibits high specific capacitance. However, the diffusion limitation of ions and chemical instability in the generally used highly basic (KOH, MXene oxidation) or acidic (H₂SO₄, CNF degradation) electrolytes limits their performance and durability. Herein, freestanding CNF/MXene cryogel membranes were prepared by deep freeze-casting (at -50 and -80 °C), using different weight percentages of components (10, 50, 90), and evaluated for their structural and physico-chemical stability in other less aggressive aqueous electrolyte solutions (Na₂/Mg/Mn/K₂-SO₄, Na₂CO₃)
