In article number 2002737 Denis Y. W. Yu, Yanwu Zhu, Wenjun Zhang and co‐workers discuss the continuous electrolyte decomposition of common carbonate‐based electrolytes, which accelerates the capacity decay of Na 2/3 Ni 1/3 Mn 2/3 O 2 . It is shown that a fluoroethylene carbonate electrolyte can suppress the successive electrolyte decomposition, thus enabling significantly improved cycle stability for Na 2/3 Ni 1/3 Mn 2/3 O 2 . Such work provides new solutions to develop low cost and durable sodium‐ion batteries for grid‐scale applications.
