Lithium metal anodes, which deliver high specific capacity, low electrochemical potential, and low density have been considered as the most ideal anode material for Li secondary batteries. However, the development of Li anodes is limited by Li dendrite formation, infinite volume effects, and unstable solid electrolyte interphase (SEI) layers. Herein, aluminum nitride (AlN) nanoflakes as an additive to stabilized Li plating, and carbon paper (CP) as three‐dimensional (3D) current collector to alleviate volume effect, are reported. The stabilization is attributed to the higher binding energy between Li and the AlN nanoflakes and a preferential adsorption on the AlN nanoflake surface compared to copper (Cu) and CP surface during Li plating. With the combination of the AlN nanoflake additive and 3D CP current collector, both dendritic Li and volume effects are remarkably inhibited.

3D碳纸锂金属电池中氮化铝纳米片状添加剂对锂枝晶的自我抑制

具有高比容量，低电化学势和低密度的锂金属阳极被认为是锂二次电池最理想的阳极材料。然而，锂阳极的发展受到锂枝晶形成，无限的体积效应和不稳定的固体电解质相间（SEI）层的限制。本文报道了氮化铝（AlN）纳米片作为稳定锂镀层的添加剂，碳纸（CP）作为三维（3D）集流体以减轻体积效应的报道。稳定归因于Li和AlN纳米薄片之间的结合能更高，并且在Li电镀过程中，AlN纳米薄片表面比铜（Cu）和CP表面优先吸附。结合使用AlN纳米片状添加剂和3D CP集电器，
