Figure 1

(a) Low-magnification TEM image of Ag15 clusters on an amorphous carbon film showing uniform size and distribution of the clusters (scale bar, 5 nm). (b) Medium-magnification TEM image of Ag15 clusters (arrows) on an Al2O3-coated carbon particle before first discharge. Occasionally, agglomeration of Ag15 clusters (large circle) is observed (scale bar, 2 nm). (c) High-resolution TEM image of an Ag15 cluster on an Al2O3-coated carbon surface (scale bar, 1 nm).
