NANOSHEET-SHAPED NICKEL METAL BY MECHANOCHEMICAL REDUCTION, AND FABRICATION METHOD OF POSITIVE ELECTRODE OF NI-BASED ALKALINE STORAGE BATTERY USING THE SAME

摘要

The present invention relates to a nanosheet-shaped nickel metal by mechanochemical reduction, and a method to manufacture an anode of a nickel-based alkaline storage battery using the same and, more specifically, the present invention provides the method to manufacture the nanosheet-shaped nickel metal by mechanochemical reduction, comprising: a step of manufacturing a nickel salt mixture by mixing a nickel salt with NaBH_4; applying shearing stress to the nickel salt mixture; and manufacturing the nanosheet-shaped nickel metal in accordance with the result of applying the shearing stress, and the method to manufacture the anode using the nickel. According to the present invention, the effect of suppressing a voltage drop of the anode and improve a discharging efficiency of the battery during discharging is expected by improving electrical conductivity of the anode by adding the nanosheet-shaped nickel metal manufactured by the mechanochemical reduction method to the anode formed with nickel hydroxide (Ni(OH)_2) powder.
