  • Patent number: 9287557
    Abstract: When an active material with low ionic conductivity and low electric conductivity is used in a nonaqueous electrolyte secondary battery such as a lithium ion battery, it is necessary to reduce the sizes of particles; however, reduction in sizes of particles leads to a decrease in electrode density. Active material particles of an oxide, which include a transition metal and have an average size of 5 nm to 50 nm, are mixed with an electrolyte, a binder, and the like to form a slurry, and the slurry is applied to a collector. Then, the collector coated with the slurry is exposed to a magnetic field. Accordingly, the active material particles aggregate so that the density thereof increases. Alternatively, the active material particles may be applied to the collector in a magnetic field. The use of the aggregating active material particles makes it possible to increase the electrode density.

  • Publication number: 20140186719
    Abstract: A method is provided for forming a sodium-containing particle electrolyte structure. The method provides sodium-containing particles (e.g., NASICON), dispersed in a liquid phase polymer, to form a polymer film with sodium-containing particles distributed in the polymer film. The liquid phase polymer is a result of dissolving the polymer in a solvent or melting the polymer in an extrusion process. In one aspect, the method forms a plurality of polymer film layers, where each polymer film layer includes sodium-containing particles. For example, the plurality of polymer film layers may form a stack having a top layer and a bottom layer, where with percentage of sodium-containing particles in the polymer film layers increasing from the bottom layer to the top layer. In another aspect, the sodium-containing particles are coated with a dopant. A sodium-containing particle electrolyte structure and a battery made using the sodium-containing particle electrolyte structure are also presented.
