In situ BaSO4 coating enabled activation-free and ultra-stable δ-MnO2 for aqueous Zn-ion batteries

Abstract

In situ BaSO4 coating, generated in the first discharging of Ba2+ pre-intercalated δ-MnO2, shortens the activation process by inducing fast proton intercalation and stabilizes the MnO2 crystal by suppressing Mn dissolution. The cathode delivers a decent electrochemical performance of 210 mA h g−1 at 1C with a 98% retention after 200 cycles.
