Abstract: Disclosed is an anode material for a sodium secondary battery. The anode material includes a tin fluoride-carbon composite composed of a tin fluoride and a carbonaceous material. The anode material can be used to improve the charge/discharge capacity, charge/discharge efficiency, and electrochemical activity of a sodium secondary battery. Also provided are a method for preparing the anode material and a sodium secondary battery including the anode material.

Abstract: Provided are a gel polymer electrolyte and a secondary battery including the same. More particularly, the gel polymer electrolyte includes a sodium cation-containing polymer from which sodium cations can be dissociated, and thus provides improved ion conductivity of sodium cations, thereby improving the electrochemical properties of a secondary battery.
