Manganese residue treatment as a new approach to manganese dioxide production

Resumo

Lithium-air batteries performance faces a challenge on the design and development of a functional cathode. Manganese dioxide is a promising material for the air cathode, due to its low cost and ability to catalyse oxygen reactions. In its preparation residues are generated that need to be treated before discard. The present study aims to prepare the manganese dioxide through a precipitation/annealing method, using as raw-material manganese based waste from electrodeposition baths utilized in a previous study, in order to synthesize novel MnOx based electrodes.
