摘要 金属锂具有高的理论比容量(3 860 mAh·g-1),低的电极电位(-3.04 V与标准氢电极相比)和低的密度(0.53 g·cm-3),是最有前途的锂二次电池用的负极材料。但仍存在循环过程中枝晶生长及其导致的低库伦效率、短循环寿命等问题。而3D锂金属负极因具有高比表面积和内部空腔能有效缓解上述问题。特别是纳米技术的发展为3D锂金属负极提供了更高效的形貌与结构。基于金属基和碳基3D锂金属负极对三维锂金属负极的设计及研究进展进行了详细的概述。

Abstract: Metallic Li with the high theoretical specific capacity (3 860 mAh·g-1), low electrode potential (-3.04 V versus the standard hydrogen electrode) and low density (0.53 g·cm-3) is regarded as the most promising anode material for Li secondary batteries. However, there are still some problems such as dendrite growth, low Coulombic efficiency and short cycle life during the cycles. The three-dimensional metallic lithium anodes can effectively alleviate the above problems due to its high specific surface area and internal cavity. The progress in nanotechnology provides appropriate 3D metallic lithium anodes characterized by highly efficient morphologies and architectures. Herein, the design and research progress of three-dimensional metallic lithium anodes is described in detail, including metal-based and carbon-based 3D metallic lithium anodes.
