ORGANIC SULFUR MATERIAL, ELECTRODE, AND LITHIUM-ION SECONDARY BATTERIES, AND PRODUCING METHOD

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, around 1066 cm, around 1150 cm, around 1245 cm, around 1270 cm, around 1453 cm, and around 1732 cmin an FT-IR spectrum.
