Three-dimensional structure having a lithium-containing adhesive and the lithium negative electrode material thereof

The present invention provides an adhesive and a negative electrode material comprising the same, wherein the adhesive comprises a conjugate. The conjugate comprises: a chitin group; a polymer group having at least one functional group selected from the group consisting of a hydroxyl group (-OH), a carboxyl group (-COOH), and an amine group (-NH 2 ) a group having an aldehyde group (-CHO) and/or an amine group (-NH 2 ). The adhesive of the present invention uses a three-dimensional network structure composed of a conjugate for a lithium battery negative electrode material, overcoming the disadvantages of the conventional negative electrode material.
