METHOD FOR A POROUS ELECTRODE CURRENT COLLECTOR FOR LITHIUM METAL BATTERY USING HYDROGEN BUBBLE AS A TEMPLATE AND ELECTRODE CURRENT COLLECTOR MANUFACTURED THEREBY

摘要

The present invention relates to a method for manufacturing a porous electrode current collector using a hydrogen bubble template and an electrode current collector manufactured thereby. The method of the present invention comprises the steps of: forming a porous copper thin film by applying overvoltage during electroplating in a copper plating solution; and washing the porous copper thin film using a volatile organic solvent and distilled water. The electrode current collector of the present invention has lithium uniformly deposited on the copper thin film with an increased surface area to expect suppression of the dendritic shape growth or the growth of the lithium inside a hole formed of copper. In addition, a washing problem generated in the porous copper thin film is solved by using a volatile organic solvent and water, and the low efficiency caused thereby during the first charging and discharging is improved.
