The present invention is a cathode active material capable of occluding and releasing lithium ions, the cathode active material comprises a nanowire of vanadium oxide (V 2 O 5 ) as a main component, the nanowire is acidified by the addition of an acidic ion exchanger A vanadate compound is added to an aqueous reaction system to prepare a sol-gel method, and a cathode active material is characterized by adjusting the specific surface area of a nanowire by controlling a reaction time.n n n The positive electrode active material including the vanadium oxide nanowire according to the present invention can not only replace the lithium transition metal oxide, which is mainly used as a conventional positive electrode active material, but also can be mass-produced, and by adjusting the length or specific surface area of the nanowire, The secondary battery including the same may exhibit high output characteristics. |
