Melanin as biological organic polymer with semiconductor properties is unique effective modifier for MnO₂ cathode and increases the energy of Li-MnO₂ battery

This article presents results on the modification of a composite mass based on MnO2 with an organic polymer – melanin. The main goal was to evaluate the possibility of increasing the efficiency of electrode processes during cycling and their stabilization. MnO2, synthesized chemically on the basis of Ukrainian manganese ores, was used for modification. This manganese dioxide has a high density (about 2.64 g/cm3), a high specific surface area (28 m2/g), and electronic conductivity also. The final product of the synthesis is γ-MnO2 powder with 5% admixture of γ-Mn2O3.
