Abstract
A negative electrode active material that includes an active material core that allows the intercalation and deintercalation of lithium ions; and a conductive material that is attached to a surface of the active material core through an organic linker. The conductive material includes at least one selected from the group consisting of a linear conductive material and a planar conductive material. The organic linker is a compound that includes a hydrophobic structure and a substituent including a polar functional group.
