报道了一种利用低温等离子体增强原子层沉积技术制备人工固体电解质界面的稳定Na金属阳极。发现Al2O3层（2.8nm）的覆盖层可以保护Na金属免受电解质分解，防止3D枝晶形成，并且显著增强其在碳酸盐基电解质中的循环稳定性。
A stable Na metal anodeis is reported by forming an artificial solid electrolyte interphase via a low-temperature plasma-enhanced atomic layer deposition technology. It is discovered that an ultrathin layer of Al2O3 layer (2.8 nm) can protect Na metal from electrolyte decomposition, prevent 3D dendrite formation, and significantly enhance its cycle stability in a carbonate-based electrolyte.
