生物质炭材料在金属锂负极中的应用

A review of biomass-derived carbon materials for lithium metal anodes

  • 摘要: 金属锂具有超高理论容量和最低还原电位,被认为是高能量密度电池负极材料的“圣杯”。然而,由于金属锂无宿主、锂枝晶不可控生长、固态电解质界面膜(SEI膜)不稳定以及“死锂”累积等一系列问题,严重制约着金属锂负极的实用化进程。生物质炭材料具有高机械强度、高导电性、高比表面积和良好的化学稳定性等特性,是金属锂宿主材料的理想候选者之一。本文综述了近年来利用生物质炭材料构建金属锂沉积骨架的研究进展。通过讨论生物质炭材料的结构、孔隙大小、孔隙率及亲锂基团修饰等对抑制金属锂枝晶生长,构筑循环稳定金属锂负极的影响,总结生物质炭材料的合理设计和应用,提出了生物质炭材料未来发展的趋势以及所面临的挑战。

     

    Abstract: Because of its high theoretical capacity and lowest reduction potential, lithium metal has been considered the “Holy Grail” anode material for high energy density battery systems. However, the practical use of lithium metal anodes (LMAs) has been plagued by a series of problems such as the inability of lithium metal to act as a host for other atoms, uncontrollable lithium dendrite growth, unstable solid-electrolyte interfaces, and “dead” lithium accumulation. Biomass-derived carbon materials are considered ideal host materials for Li metal because of their high mechanical strength, high conductivity, high surface area, and good chemical stability. This review presents a historical framework of using biomass-derived carbon materials as a framework for LMAs. The design and use of biomass-derived carbon materials in suppressing Li dendrite growth and constructing stable LMAs are summarized. The impact of the structure, porosity and “lithiophilicity” modification on the performance of LMAs is discussed. Prospects for the use of biomass-derived carbon materials and the challenges faced are suggested.
