Abstract：
Lithium metal batteries (LMBs), with high energy densities, are strong contenders for the next generation of energy storage systems. Nevertheless, the unregulated growth of lithium dendrites and the unstable solid electrolyte interphase (SEI) significantly hamper their cycling efficiency and raise serious safety concerns, rendering LMBs unfeasible for real-world implementation. Covalent organic frameworks (COFs) and their derivatives have emerged as multifunctional materials with significant potential for addressing the inherent problems of the anode electrode of the lithium metal. This potential stems from their abundant metal-affine functional groups, internal channels, and widely tunable architecture. The original COFs, their derivatives, and COF-based composites can effectively guide the uniform deposition of lithium ions by enhancing conductivity, transport efficiency, and mechanical strength, thereby mitigating the issue of lithium dendrite growth. This review provides a comprehensive analysis of COF-based and derived materials employed for mitigating the challenges posed by lithium dendrites in LMB. Additionally, we present prospects and recommendations for the design and engineering of materials and architectures that can render LMBs feasible for practical applications.
摘要：
锂金属电池（LMB），具有高能量密度，是下一代储能系统的有力竞争者。然而，锂枝晶的无序生长和不稳定的固体电解质界面（SEI）显著阻碍了它们的循环效率，并引起了严重的安全问题，渲染LMB对于现实世界的实现是不可行的。共价有机骨架(COF)及其衍生物已经成为具有解决锂金属阳极电极固有问题的显著潜力的多功能材料。这种潜力源于它们丰富的金属仿射官能团，内部通道,和广泛可调的体系结构。原始COF，它们的衍生物，和COF基复合材料可以通过增强导电性有效地引导锂离子的均匀沉积,运输效率,和机械强度，从而减轻锂枝晶生长的问题。这篇综述全面分析了用于减轻LMB中锂枝晶带来的挑战的COF基和衍生材料。此外,我们提出了材料和体系结构的设计和工程的前景和建议，这些材料和体系结构可以使LMB在实际应用中可行。
