Disclosed are a positive active material composition for an energy storage device (1), a positive electrode (2), and an energy storage device including the same. The positive active material composition includes: a carbon-based additive including a hydroxyl group (-OH) and an enol group (-C=C-OH) on the surface, having a peak area ratio (OH/C=COH) of a hydroxyl group peak area and an enol group peak area of an infrared spectroscopy (FT-IR) spectrum ranging from about 0.5 to about 10, having a specific surface area of about 50m 2 /g to about 3000m 2 /g, and having a carbon content of greater than about 85wt%; a positive active material; a conductive material; and a binder. |
