Abstract

With the growing demand for high-energy-density rechargeable batteries, lithium metal anodes have reemerged as a promising alternative to conventional graphite anodes in lithium-ion batteries. Lithium metal boasts exceptional energy storage characteristics, yet its practical application has been impeded by dendritic growth issues. Extensive research has explored various solutions, including electrode engineering through surface modification and 3D structural hosts, which often involve intricate designs and processes. This study introduces an effective approach to govern lithium metal nucleation and growth, leveraging the synergistic effects of a lithiophilic layer and surface energy diversification. Inspired by the structure of standard copper mesh grids used in transmission electron microscopy (TEM), we illustrate how subtle topographic modifications can provide a viable path to anode-free lithium metal batteries. This research represents a significant stride towards accelerated advancements in lithium metal batteries, promising higher energy density and enhanced safety for energy storage solutions.

受透射电子显微镜取样网格启发的锂金属电池阶梯式网格主机

摘要随着对高能量密度可充电电池的需求日益增长，锂金属阳极作为锂离子电池中传统石墨阳极的替代品重新崛起。锂金属具有优异的储能特性，但其实际应用却受到树枝状生长问题的阻碍。广泛的研究探索了各种解决方案，包括通过表面改性和三维结构宿主进行电极工程，这通常涉及复杂的设计和工艺。本研究介绍了一种有效的方法，利用亲锂层和表面能量多样化的协同效应来控制锂金属的成核和生长。受透射电子显微镜（TEM）中使用的标准铜网栅结构的启发，我们说明了微妙的地形修改如何为无阳极锂金属电池提供可行的途径。这项研究标志着锂金属电池在加速发展方面迈出了重要一步，有望为能源存储解决方案带来更高的能量密度和更强的安全性。
