Neutron powder diffraction data have been collected for ..beta..-PbO/sub 2/ obtained from lead-acid battery plates cycled in H/sub 2/SO/sub 4/ and D/sub 2/SO/sub 4/. A comparison of total scattering cross sections for the hydrogenated sample vs. the deuterated sample indicates a bulk hydrogen concentration of 0.21 H atoms per PbO/sub 2/ unit. Rietveld refinements of the data yield the expected tetragonal ..beta..-PbO/sub 2/ structure, P4/sub 2//mnm, with a 3-5% vacancy concentration on the lead sites. These results suggest that at least part of the hydrogen is incorporated into the ..beta..-PbO/sub 2/ crystalline lattice.
