  • Method for making vanadium pentoxide-based active material for a cathode of an alkali metal ion battery, the vanadium pentoxide-based active material, the cathode, and the alkali metal ion battery
    Patent number: 11264601
    Abstract: A method for making a vanadium pentoxide-based active material for a cathode of an alkali metal ion battery includes steps of: a) preparing an aqueous solution of a triazine derivative of Formula (I) wherein each R independently represents hydrogen or an amino group; and b) adding vanadium pentoxide to the aqueous solution of the triazine derivative under stirring, so as to permit condensation among hydrolyzed vanadium pentoxide along with self-assembly of the triazine derivatives to obtain a reaction solution containing the active material.

  • Method for stripping non-superconductive AG-based sheath formed on a wire
    Patent number: 5647116
    Abstract: A non-superconductive Ag-based sheath formed surrounding a superconducting tape or wire is stripped by placing a Bi- or Pb-based metal material on the Ag-based sheath to be removed; and then heating the Bi- or pb-based metal material to 250.degree. C.-450.degree. C. to dissolve the Ag-based sheath; and removing the dissolved Ag-based sheath.
