Synthesis of Na-MnO₂ Electrodes and Its Microstructural and Electrochemical Characterization.

Abstract

The batteries are portable devices that allow to storage chemical energy and provide electric current directly. Inside the batteries, one of the most used materials is Lithium, which includes a large number of applications. In recent years, the investigation of ion-Na and Na-MnO₂ batteries has been intensified as an alternative to Li-MnO₂ batteries. Lithium and sodium have many similar chemical characteristics and their low cost and the wide availability of sodium are factors that can make them more used in the future. An important concern in the increase of lithium battery production lies in the limited natural resources provided by this material, and its heterogeneous distribution in the earth's crust This work is focused on the preparation of Na-MnO₂ electrodes for secondary batteries and the microstructural, structural, and electrochemical characterization of them. The synthesis technique was hydrothermal non-conventional type. The contributions are found in the comparison of the properties and electronic elements of the synthesized materials. The impact of this project is on the possible use of Na-MnO₂ electrodes as an alternative material to the one currently used in Li-MnO₂ batteries. Figure 1
