Poster summary
- Among the various cathode materials reported, the tunnel-type Na0.44MnO2 has attracted great interest. Unfortunately, the Na storage performance of this material is affected by Mn disproportionation, resulting in a rapid capacity drop and poor rate performance. To address these shortcomings, a Li substituted-induced tunnel/spinel heterostructured cathode material is successfully synthesized and comprehensively studied. Li dopants can act as pillars in the crystal framework to suppress unfavorable phase transitions and enhance structural reversibility. In addition, the additional spinel structure provides a new three-dimensional Na+ ion transport channel, effectively improving the ion diffusion kinetics.
