Low‐Cost, High‐Strength Cellulose‐based Quasi‐Solid Polymer Electrolyte for Solid‐State Lithium‐Metal Batteries

A quasi-solid-state lithium-ion battery prepared by low-cost cellulose acetate exhibits extraordinary electrochemical stability, as reported by Lei Tian, Caizhen Zhu et al. in their Research Article (e202302767). The cellulose part in cellulose acetate is like a mountain forest. The esterified side groups are like the Great Wall built between the mountain forest, providing high-speed and stable transport channels for lithium ions.
