  • Method for producing metal shaped article having porous structure
    Patent number: 11534826
    Abstract: A method for producing a metal shaped article having a porous structure includes a mold formation step of forming a mold having a plurality of columnar structures extending from a substrate by performing a resin material supply step of supplying a liquid containing a resin material to a plurality of places of the substrate at intervals in two directions crossing each other, and a curing step of curing the liquid, a sintering target material supply step of supplying a sintering target material to the mold, a removal step of removing the substrate, a degreasing step of degreasing the columnar structures, and a sintering step of sintering the sintering target material.
    Type: Grant

  • Sodium-conducting solid electrolyte
    Patent number: 9966629
    Abstract: A sodium-conductive solid-state electrolyte material includes a compound of the composition Na10MP2S12, wherein M is selected from Ge, Si, and Sn. The material may have a conductivity of at least 1.0×10?5 S/cm at a temperature of about 300K and may have a tetragonal microstructure, e.g., a skewed P1 crystallographic structure. Also provided are an electrochemical cell that includes the sodium-conductive solid-state electrolyte material and a method for producing the sodium-conductive solid electrolyte material via controlled thermal processing parameters.
