Multifunctional Tunnel Structural Interfacial Modulation Promises Fast-Charge and Long-Life Na-Layered Oxides
Na-layered oxides are famous for their environmental friendliness and facile synthesis, however, developing cathodes with fast Na+ transport kinetics, robust structure, and air/water stability to realize fast-charge and long-life layered oxide cathodes for sodium-ion batteries (SIBs) remains a great challenge. Herein, we propose the concept of multifunctional tunnel interfacial modulation to stabilize the phase structure of P2-Na2/3Ni1/3Mn1/3Ti1/3O2. Relying on the unique structure of the Na0.44MnO2 with S-channel, the modified electrode prepared with an aqueous binder achieves capacity retention of 80.87% after 4000 cycles at 2C. The calculation results of stress simulation reveal that the tunnel structure could dissipate the mechanical stress of the P2 phase upon cycling. Overall, such multifunctional tunnel interfacial modulation provides a new research direction for the development of fast-charge and long-life SIBs.
