Construction of layered Na<sub>0.44</sub>MnO<sub>2</sub> cathode by facile Na<sup>+</sup>/K<sup>+</sup> exchange strategy to enhance capacity
The Na<sup>+</sup>/K<sup>+</sup> ion-exchange overcomes the conventional synthetic method's limitations on the Na<sub>0.44</sub>MnO<sub>2</sub> structure. It induces the structural transformation of Na<sub>0.44</sub>MnO<sub>2</sub> from tunnel to layered. The novel layered Na<sub>0.44</sub>MnO<sub>2</sub> exhibits superior capacity with high structural stability. This work offers a universal strategy for designing high-performance cathodes.
