Description
Summary: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.
