High-entropy Prussian Blue shell enabling the high-rate and long cycling stability of Mn-PBA cathode for sodium-ion batteries
Abstract
To address the poor cycle stability of Mn-PBA based cathode, herein, we introduce a high-entropy Prussian Blue shell onto the Mn-PBA surface. Due to the synergistic effect, the rate performance and long-cycle stability of this new type of cathode have been significantly improved. The work provides a new paradigm for the development of PBA based SIBs cathode.
