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 fuel cell catalyst and a manufacturing method thereof. The fuel cell catalyst of the present disclosure can be used to manufacture a membrane electrode assembly having a catalyst layer of high density and high dispersion by solving the problem of aggregation of catalyst particles occurring during the formation of the catalyst layer, by using a catalyst including a polydopamine-coated support.
In addition, the method for manufacturing a fuel cell catalyst of the present disclosure does not require a solvent because the catalyst including the polydopamine-coated support and the halide in solid phase are simply heat-treated by solid-to-solid dry synthesis and allows manufacturing of a fuel cell catalyst in short time because a washing process using a solvent and an extraction process for sampling are unnecessary after the synthesis.

Abstract: The present disclosure relates to a fluorine-doped tin oxide support, a platinum catalyst for a fuel cell comprising the same, and a method for producing the same. The present disclosure has a high electrical conductivity and electrochemical durability by doping fluorine to the tin oxide-based support through an electrospinning process. Thus, while resolving a degradation issue of the carbon support in the conventional commercially available platinum/carbon (Pt/C) catalyst, the present disclosure is designed to minimize an electrochemical elution of dopant or tin, which is a limitation of the tin oxide support itself and has excellent performance as a catalyst for a fuel cell.
