Electrochemical activity of lead dioxide electrode in the lead-acid battery system may be related to the incorporation of hydrogen defect in the material. The coherent and incoherent neutron-scattering cross sections of Pb, O, and H atoms are sufficiently different from each other to assure meaningful results from neutron scattering studies. A preliminary analysis of experimental results of inelastic incoherent neutron scattering (IINS) study on ..beta..-PbO/sub 2/ (Space Group P/sub 42/ mnm) from cycled lead-acid battery plates, in addition to yielding the vibrational spectrum representative of motions of Pb and O atoms in the crystal lattice, provided for the first time the evidence for the presence of tightly bound protons in the solid phase. We report in this paper on the observed vibrational modes for ..beta..-PbO/sub 2/ material prepared chemically and obtained from cycled battery plates.
