The transition toward sustainable energy systems requires high-energy-density storage solutions to support electric vehicles, grid storage, and portable electronics. LMBs, with their ultra-high theoretical capacity and low redox potential, represent a promising next-generation technology. However, their widespread adoption is hampered by safety risks and poor cycle life arising from dendritic lithium growth and unstable solid-electrolyte interphases. These challenges limit LMBs' practical application, especially under fast-charging and high-current conditions, and have prevented commercialization despite their significant potential.In this study, we introduce a bikitaite-infused cellulose-based separator that addresses these critical limitations. By leveraging the ion-conductive properties and nanoporous structure of bikitaite within a sustainable cellulose matrix, this separator regulates lithium-ion flux, enhances ion desolvation, and suppresses dendrite formation. The separator promotes uniform lithium deposition, enabling stable cycling, fast charging, and high-rate performance—even at low temperatures. Furthermore, the use of abundant, low-cost materials such as bikitaite and cellulose aligns with green chemistry principles, offering a scalable and environmentally friendly solution.This work presents a practical strategy for improving the safety and longevity of LMBs, contributing to the development of safer, high-performance energy storage devices essential for a sustainable energy future.
