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.
向可持续能源体系转型亟需高能量密度储能解决方案,以支撑电动汽车、电网储能及便携式电子设备的发展。锂金属电池(LMBs)凭借超高理论比容量与极低氧化还原电位,成为极具潜力的下一代储能技术。然而,锂枝晶生长与不稳定的固体电解质界面层所引发的安全隐患及循环寿命不佳问题,阻碍了其大规模商业化应用。这些难题限制了锂金属电池的实际应用场景,尤其是在快充与大电流工况下,即便其具备极高的应用潜力,仍迟迟未能实现商业化。本研究开发了一种掺杂比基塔石的纤维素基隔膜,可有效解决上述关键局限。该隔膜依托可持续纤维素基质中比基塔石的离子传导特性与纳米多孔结构,可调控锂离子通量、强化离子脱溶剂化过程并抑制枝晶生成。该隔膜可促进锂的均匀沉积,实现稳定循环、快充能力与高倍率性能,甚至在低温环境下仍可保持优异表现。此外,所采用的比基塔石与纤维素均为储量丰富、成本低廉的原材料,符合绿色化学理念,可提供可规模化且环境友好的解决方案。本研究为提升锂金属电池的安全性与循环寿命提供了切实可行的方案,有助于开发出更安全、高性能的储能设备,为可持续能源未来筑牢基础。
