Abstract
The surface-modification of manganese dioxide has been carried out for the purpose of increasing the discharge capacity of alkaline manganese battery. The characteristics of the obtained material has been investigated by using XAFS (X-ray absorption fine structure), Raman spectroscopy and ESR. It seems that composite oxide of Ti and Mn is formed on the surface of the surface-modified manganese dioxide (SMMD) particles. XRD measurement data on the discharged product demonstrates that SMMD suppresses the byproduct, and discharge characteristics of SMMD is improved compared to the conventional manganese dioxide.
