Anode, all-solid-state battery comprising the same, and method for manufacturing the same

A method for manufacturing an anode, the method comprising:

• preparing a carbon nanotube sheet;
• doping the carbon nanotube sheet with a metal particle;
• and
• depositing the carbon nanotube sheet onto an anode current collector,
• wherein the carbon nanotube sheet comprises a carbon nanotube strand having an average length ranging from about 1 m to 100 m.

A method for manufacturing an anode, the method comprising:

• immersing a sheet-type carbon nanotube in an aqueous surfactant solution comprising about 0.001M to 0.1M cetyltrimethylammonium bromide (CTAB) for a time ranging from about 10 minutes to 3 hours;
• vacuum-drying the surfactant-treated carbon nanotube sheet for about 12 hours to 36 hours;
• immersing the dried carbon nanotube sheet in a colloid solution comprising silver nanoparticles, silver nitrate (AgNO3) and sodium borohydride (NaBH4), the colloid solution having a concentration of about 0.001 M to 1.0M, for a time ranging from 10 minutes to 24 hours;
• and
• vacuum-drying the silver-nanoparticle-doped carbon nanotube sheet for about 12 hours to 356 hours to obtain the anode.
