The Cover Feature illustrates the electrodeposition of Na+ ions on a sodium metal anode. Using electrolytes based on carbonate solvents and containing the most common electrolyte salt, i. e., sodium hexafluorophosphate, leads to dendrite deposits. On the other hand, reversible globular sodium electrodeposition occurs when using sodium cyclopentadienide, as a new type of electrolyte. This could enhance both the cycle life and the coulombic efficiency in sodium metal batteries. More information can be found in the Communication by M. Binder et al.

封面人物:环戊二烯酸钠作为一种新型的钠电池电解质(ChemElectroChem 2/2021)

封面特征示出的Na的电沉积+离子上的金属钠阳极。使用基于碳酸盐溶剂并包含最常见的电解质盐的电解质,即 例如,六氟磷酸钠会导致枝晶沉积。另一方面,当使用环戊二烯酸钠作为新型电解质时,发生可逆的球状钠电沉积。这可以提高钠金属电池的循环寿命和库伦效率。有关更多信息,请参见M. Binder等的《通讯》。
