Production and characterisation of electrolytically doped manganese dioxide

A laboratory batch process for the production of titanium-doped electrolytic manganese dioxide (EMD) in the amount of some hundred grammes is described. The product is characterised by chemical analysis, electrochemical behaviour, X-ray diffraction, and electron microscopy (TEM, ESI) including local electron energy loss spectroscopy (EELS) analysis. Suggestions for possible improvement of the doping process and for the preparation of the product are given.
