Key Points

This research aims to develop a durable and high-rate cathode for sodium-ion batteries using a core-shell composite.
Prepared CuFeMnHCF@CuHCF composite via one-pot co-precipitation and ion exchange method.
Characterized the structural properties and electrochemical performance of the composite.
The core-shell structure showed significant improvement in cycling stability and rate capability.
Achieved a retention rate of over 90% after 200 cycles, indicating durability.
Enhanced electrochemical kinetics due to the mitigation of Jahn-Teller distortion.

Implication

Demonstrates improved performance in sodium-ion batteries, suggesting enhanced energy storage capabilities.

Abstract

A core-shell CuFeMnHCF@CuHCF composite was prepared via continuous one-pot co-precipitation and ion exchange method. The monoclinic Cu-doped FeMnHCF core and the cubic Cu2Fe(CN)6 shell can mitigate Jahn-Teller distortion and suppress...
