Disclosed are an electrode for secondary batteries containing a high-density carbon defect structure and a method of producing the same. The electrode can prevent deterioration of battery performance due to dendrite formation by inhibiting self-diffusion and aggregation of metal nuclei, and can exhibit an unprecedentedly high number of charge/discharge cycles and excellent energy efficiency by uniformly electrodepositing metal ions on the surface of the electrode. When the method of producing a carbon electrode for a secondary battery is used, an electrode containing a high-density carbon defect structure can be produced, and thus a battery with higher efficiency and a longer lifespan can be produced. The secondary battery comprising the electrode is useful for fields related to medium/large-scale energy storage technology, in particular, for mobile devices, batteries, and renewable-energy power generation systems.

Electrode for secondary batteries containing high-density carbon defect structure and method of producing the same

Provided are a positive electrode for a Zn&#x2014;Br battery, a Zn&#x2014;Br battery including the same, and a method of manufacturing the positive electrode for a Zn&#x2014;Br battery. The positive electrode for a Zn&#x2014;Br battery includes a carbon body doped with pyridinic nitrogen. The Zn&#x2014;Br battery includes a negative electrode including a transition metal coated with zinc, the positive electrode; and an electrolyte. A pH of the electrolyte is in a range of 1.5 to 5.
