METHOD FOR MANUFACTURING PATTERN CURRENT COLLECTOR FOR SEAWATER BATTERY AND THE PATTERN CURRENT COLLECTOR FOR SEAWATER BATTERY MANUFACTURED USING THE SAME

摘要

The present invention relates to a pattern current collector for a seawater battery manufactured according to a method for manufacturing a pattern current collector for a seawater battery, and more particularly, to an aluminum foil on which a pattern shadow mask having a pattern in which a plurality of circular holes is formed at regular intervals is placed. By placing a copper metal thin film or silver metal thin film in an evaporator and depositing a copper metal thin film or a silver metal thin film to form a copper metal thin film or a silver metal thin film on an aluminum foil not covered by a pattern shadow mask to produce a pattern current collector for a seawater battery in which a predetermined pattern is formed, a predetermined pattern Since sodium ions are selectively controlled to move to the formed copper metal thin film or silver metal thin film, it can be used as an optimal pattern current collector capable of stable charging and discharging reactions for a long time, which can be applied as a negative electrode for a reversible seawater battery.
