Abstract: A method for preparing a lithium alloy as an anode material includes the following steps: heating lithium metal into a molten state in an environment with a dew point not higher than ?50° C. and an oxygen content not higher than 10 ppm; adding a transition metal to the molten lithium metal, maintaining the temperature for 5-15 minutes, and uniformly mixing to form a molten alloy; cooling the molten alloy to room temperature to obtain the lithium alloy as the anode material. The preparation method of the present invention is simple and feasible with less cost. The prepared lithium alloy as the anode material can effectively improve the coulombic efficiency and cycle lifespan of the lithium battery.

Abstract: A process for preparing a metal nanostructure having metal masses with zero valence aligned on a substrate surface wherein the size and shape of the metal masses are controlled is described. The process can include preparing a micro phase separation membrane of an amphiphilic block copolymer on a substrate and then exposing the membrane to a solution containing metal ions; drying the membrane to form a micro phase separation membrane with the metal ions localized in hydrophilic segments of the membrane; and irradiating vacuum ultraviolet light on the membrane to reduce the metal ions and to remove organic materials.

Abstract: The objective is to present a metal nanostructure having metal masses with zero valence aligned on a substrate surface wherein the size and shape of the metal masses are controlled and a manufacturing process thereof. A micro phase separation membrane comprising an amphiphilic block copolymer assumes a state that contains numerous micro diameter hydrophilic cylinders inside the membrane in the direction perpendicular to the membrane surface. The membrane is prepared using a solution containing an amphiphilic block copolymer and desired metal ions or by bringing a micro phase separation membrane of an amphiphilic block copolymer in contact with a solution containing metal ions after the membrane is formed to localize the metal ions in the hydrophilic micro diameter cylinders.
