摘要： A crystalline nanowire and method of making a crystalline nanowire are disclosed. The method includes dissolving a first nitrate salt and a second nitrate salt in an acrylic acid aqueous solution. An initiator is added to the solution, which is then heated to form polyacrylatyes. The polyacrylates are dried and calcined. The nanowires show high reversible capacity, enhanced cycleability, and promising rate capability for a battery or capacitor.

摘要： Composite materials containing sulfurized polymers and sulfur-containing particles can be used in lithium-sulfur energy storage devices as a positive electrode. The composite material exhibits relatively high capacity retention and high charge/discharge cycle stability. In one particular instance, the composite comprises a sulfurized polymer having chains that are cross-linked through sulfur bonds. The polymer provides a matrix in which sulfide and/or polysulfide intermediates formed during electrochemical charge-discharge processes of sulfur can be confined through chemical bonds and not mere physical confinement or sorption.

摘要： Particular functional nanocomposite materials can be employed as electrodes and/or as electrodes in energy storage systems to improve performance. In one example, the nanocomposite material is characterized by nanoparticles having a high-capacity active material, a core particle having a comminution material, and a thin electronically conductive coating having an electronically conductive material. The nanoparticles are fixed between the core particle and the conductive coating. The comminution material has a Mohs hardness that is greater than that of the active material. The core particle has a diameter less than 5000 nm and the nanoparticles have diameters less than 500 nm.
