Title:
PATTERNING FOR LITHIUM METAL AND ELECTROCHEMICAL DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/128321
Kind Code:
A1
Abstract:
The present invention can produce large quantities of patterned lithium metal foils at one time by forming predetermined patterns on the surface of lithium metal, using a method in which lithium metal is physically pressed onto a silicon wafer previously embossed or intaglio-engraved with predetermined patterns, or liquid lithium is applied to the same silicon wafer, followed by cooling. In addition, the present invention can advantageously perform patterning in various shapes over a wide area, and minimize non-uniform patterns which may be caused by the difference in pressing pressure. The so-patterned lithium metal has superior reversibility to the conventional lithium metal and thus can greatly improve the lifespan of a battery.
