摘要： Some variations provide a process for additive manufacturing of a nanofunctionalized metal alloy, comprising: providing a nanofunctionalized metal precursor containing metals and grain-refining nanoparticles; exposing a first amount of the nanofunctionalized metal precursor to an energy source for melting the precursor, thereby generating a first melt layer; solidifying the first melt layer, thereby generating a first solid layer; and repeating many times to generate a plurality of solid layers in an additive-manufacturing build direction. The additively manufactured, nanofunctionalized metal alloy has a microstructure with equiaxed grains. Other variations provide an additively manufactured, nanofunctionalized metal alloy comprising metals selected from aluminum, iron, nickel, copper, titanium, magnesium, zinc, silicon, lithium, silver, chromium, manganese, vanadium, bismuth, gallium, or lead; and grain-refining nanoparticles selected from zirconium, tantalum, niobium, titanium, or oxides, nitrides, hydrides, carbides, or borides thereof, wherein the additively manufactured, nanofunctionalized metal alloy has a microstructure with equiaxed grains.

摘要： The solvated metal particle-coating system includes a metal additive and a polar outer-sphere electron transferring solvent. The metal additive is solvated in the polar outer-sphere electron transferring solvent. The polar outer-sphere electron transferring solvent may include liquid ammonia, methylamine, and/or hexamethylphosphoramide. The metal additive may include an alkali metal and/or an alkaline earth metal. The solvated metal additive within the polar outer-sphere electron transferring solvent may be used to coat a metal particle and/or a metalloid particle as a layer. As the polar outer-sphere electron transferring solvent evaporates, the solvated metal additive is coupled to the metal particle and/or the metalloid particle.

摘要： Disclosed are a lithium metal composite electrode material for a lithium metal battery, a preparation method for the same, and an electrode, battery, battery module, battery pack and apparatus comprising the same. The lithium metal composite electrode material comprises: lithium metal particles and a lithium-containing conductive layer serving as a supporting framework, the supporting framework being filled with the lithium metal particles; wherein the lithium-containing conductive layer comprises an inorganic lithium compound and a lithium alloy. The lithium metal composite electrode material can solve the problems that, when lithium metal is used as a negative electrode, the electrolyte is easily consumed, and lithium dendrites are easily produced, deposited and dissolved to change electrode thickness, which in turn affects the cycle stability, electrical performance and structural stability of the battery, so as to achieve the purpose of improving the structural stability and cycle stability of the lithium metal electrode.

摘要： A method of producing metallic sodium powders. The method includes immersing one or more solid pieces of sodium metal in an organic liquid containing a hydrocarbon oil. The solid piece (s) of sodium metal immersed in the hydrocarbon oil is (are) then subjected to ultrasonic irradiation, wherein the solid piece of sodium metal is fragmented to form sodium powder, resulting in a dispersion of the sodium powder in the organic liquid. The dispersed sodium powder is then separated from the organic liquid, resulting in metallic sodium powder. A method of presodiation of an anode in an electrochemical cell. The method includes adding sodium metal powders to the surface of the anode either as a dry powder or as a suspension of the sodium particles in an organic liquid.
