Zusammenfassung:It is an object of the present invention to provide a novel organic sulfur material which is capable of improving a charge/discharge capacity and cycle characteristics, an electrode comprising the organic sulfur material, that is, a positive electrode or a negative electrode, and a lithium-ion secondary battery comprising the electrode. Provided is an organic sulfur material comprising a sulfur-modified acrylic resin, wherein an acrylic resin has peaks around 756 cm-1, around 1066 cm-1, around 1150 cm-1, around 1245 cm-1, around 1270 cm-1, around 1453 cm-1, and around 1732 cm-1 in an FT-IR spectrum.
