| 内容記述（抄録等） | Layered manganese dioxide (MnO_2) films intercalated with Li^+, Na^+ or Mg^<2+> ions were synthesized by a one-step electrochemical method. The electrodeposition was potentiostatically performed by applying an anodic potential of 1.0 V vs. Ag/AgCl in an aqueous MnSO_4 solution containing a perchlorate salt of the cation. The electrodeposited oxide films have a birnessite-type layered structure with alkali cations and water molecules between manganese oxide layers. The galvanostatic charge-discharge experiments performed in 1 M LiPF_6-DME/PC solution indicated that the Mg_<2+>-intercalated MnO_2 electrode exhibits an initial discharge capacity as large as 140 mAh g^<-1> and it shows a better capacity retention during cycling as compared with the Li^+- or Na^+-intercalated MnO_2 electrode.
