Tunnel/Layer Composite Na_0.44MnO₂ Cathode Material with Enhanced Structural Stability via Cobalt Doping for Sodium-Ion Batteries.

ABSTRACT: Sodium-ion batteries (SIBs) are the most promising alternative to lithium-ion batteries (LIBs) due to their low cost and environmental friendliness; therefore, enhancing the performance of SIBs' components is crucial. Although most of the studies have focused on single-phase cathode electrodes, these materials have difficulty in meeting the requirements in practice. At this point, composite materials show superior performance due to balancing different structures and are offered as an alternative to single-phase cathodes. In this study, we synthesized a Na_0.44MnO₂/Na_0.7MnO_2.05 composite material in a single step with cobalt substitution. Changes in the crystal structure and the physical and electrochemical properties of the composite and bare str
