Abstract:
The present invention relates to an ink composition containing a multifunctional adhesive suitable for a three-dimensional (3D) printer and the use thereof. The multifunctional adhesive of the present invention contains a compound with a catechol group and exhibits excellent adhesion to various materials (e.g. dry plaster powders, polymers, metals, ceramics, and composite materials). The use of the ink composition of the present invention containing the multifunctional adhesive enables the processing of various functional materials that were difficult to fabricate into a 3D structure. Therefore, it is highly likely that the ink composition of the present invention can effectively create a market for functional materials for a 3D printer and find new areas of application (e.g. automotive, medical, fashion, aviation/aerospace, construction, consumer electronics, entertainment, etc.).
Abstract:
Provided are a negative electrode used for a secondary battery and capable of solving a problem caused by volume expansion of a lithium-negative electrode material alloy, and a manufacturing method thereof. A method of manufacturing a negative electrode for a secondary battery includes preparing a substrate, forming one or more nanorods by etching the substrate with an etching gas including oxygen, forming a metal electrode on the substrate and the nanorods, and forming a negative electrode active material layer on the metal electrode.
