  • Patent number: 9302324
    Abstract: The invention proposes a novel method for the fabrication of regular arrays of MNWs using solid-state reduction (SSR). Using this method copper (Cu), silver (Ag), and palladium (Pd) nanowire (NWs) arrays were synthesized using anodic alumina membranes (AAMs) as templates. Depending on the metal loading used the NWs reached different diameters.

  • Patent number: 9011810
    Abstract: An electrode material obtained using a polyol process and a synthesis method is provided. The synthesis method includes steps of preparing a mixed solution by mixing a transition metal compound, a polyacid anionic compound and a lithium compound with a polyol solvent; and obtaining a resultant product by reacting the mixed solution in a heating apparatus. There is an advantage in that the electrode material, which has crystallinity due to a structure such as an olivine structure or a nasicon structure, can be synthesized using a polyol process at a low temperature without performing a heat treatment proces. The nanoelectrode material synthesized by the method has a high crystallinity, uniform particles, and a structure having a diameter ranging from several nanometers to several micrometers. Further, the electrode material has a high electrochemical stability.
