Abstract: The present disclosure relates to an anode electrode active material for a secondary battery containing nickel cobalt molybdenum oxide, an anode electrode for a secondary battery including the same, a secondary battery including the anode electrode for a secondary battery, and a method for manufacturing the same. The novel anode electrode material for a sodium secondary battery containing nickel cobalt molybdenum oxide according to the present disclosure allows intercalation/deintercalation reaction of sodium ion during charge/discharge and does not undergo significant volume change during the intercalation reaction because structure is maintained stably during repeated charge/discharge. As a result, electrode damage and electric short circuit are decreased and, thus, improved electrochemical characteristics can be achieved in long-life and high-rate capability.
In addition, the novel anode electrode material for a sodium secondary battery containing nickel cobalt molybdenum oxide is advantageous in that it can be synthesized easily via a simple process such as a one-pot reaction based on a hydrothermal synthesis process.

Abstract: The present disclosure relates to a cathode active material for a sodium ion secondary battery having high reversible capacity and excellent cycle characteristics, and a method for preparing the same. The cathode active material for a sodium ion secondary battery shows high reversible capacity and excellent cycle characteristics, when it is applied to a secondary battery. Therefore, when the cathode active material is used for manufacturing a cathode for a sodium ion secondary battery and the cathode is applied to a sodium ion secondary battery, the battery can substitute for the conventional expensive lithium ion secondary battery and can be applied to various industrial fields.
