Abstract
• Cellulose nanocrystals were tested as green binders for K-ion battery anodes. • Enzymatic CNCs showed highest capacity and 97 % retention after 100 cycles. • CNCs enabled improved electrode morphology and reduced impedance. • Binders were electrochemically stable within 0.01–3 V vs. K⁺/K. • CNCs outperformed CMC in capacity, reversibility and cycling stability. The development of sustainable and efficient binder materials is crucial to improve the performance and environmental compatibility of potassium-ion batteries (KIBs). In this study, we investigate the use of cellulose nanocrystals (CNCs) as eco-friendly binders for carbon-based anodes for KIBs. Three types of CNCs are synthesized from microcrystalline…
