Up until now, dendritic Li growth during repeated plating/stripping reactions has been a significant hurdle for the commercialization of Li metal anode. This phenomenon is strongly related to the dead Li evolution, unstable solid electrolyte interface (SEI) layer, and low Coulombic efficiency. However, existing reports on carbonate-based electrolytes, even with the addition of various additives, show no complete suppression of dendritic Li growth. Herein, we introduce a remarkably unique homogeneous Li growth induced by a combination of various solvents and a LiPF₆ salt. This behavior was found to be independent of the surface roughness of the electrode and was confirmed by the operando visualization based on synchrotron X-ray and visible light sources. Moreover, its practical possibilities were validated by the uniform Li deposition on a three-dimensional Cu current collector and the electrochemical performance on various Li metal battery systems.

协同调节电解液中与表面粗糙度无关的均质锂镀层

到目前为止，在反复电镀/剥离反应中枝晶锂的生长一直是锂金属负极商业化的重大障碍。这种现象与死锂析出、不稳定的固体电解质界面（SEI）层和低库仑效率密切相关。然而，现有关于碳酸盐基电解质的报道，即使添加了各种添加剂，也没有完全抑制枝晶锂的生长。_{在此，我们介绍了一种由各种溶剂和 LiPF 6}组合诱导的非常独特的均质锂生长。盐。发现这种行为与电极的表面粗糙度无关，并通过基于同步加速器 X 射线和可见光源的操作可视化得到证实。此外，通过三维铜集流体上的均匀锂沉积和各种锂金属电池系统的电化学性能验证了其实际可能性。
