Sodium Ion Batteries: Toward High Energy Density All Solid‐State Sodium Batteries with Excellent Flexibility (Adv. Energy Mater. 12/2020)

Abstract

In article number 1903698, Xiayin Yao, Zhong-Shuai Wu, Yan Yu and co-workers design an ultrahigh energy density (1503 Wh kg?1 based on the cathode active material) aqueous Zn?Mn2+ battery by coupling an acid-alkaline dual electrolyte and dual dissolution/deposition reactions of both the anode and cathode. The new Zn?Mn2+ batteries show high coulombic efficiency and excellent cycling stability.
