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.
