Abstract: Disclosed is an alignment apparatus that aligns a treatment object having a notch. The alignment apparatus includes a support member on which the treatment object is positioned, a driving unit configured to rotate the support member, a pushing member configured to move the treatment object to a proper location on the support member by applying a force to a side surface of the treatment object positioned on the support member, a notch detecting unit configured to detect whether the notch of the treatment object is located at a specific location, and a controller configured to control the driving unit such that the notch of the treatment object is located at the specific location by rotating the support member.

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.

Abstract: The present invention includes compositions and methods of making cation-substituted and fluorine-substituted spinel cathode compositions by firing a LiMn2?y?zLiyMzO4 oxide with NH4HF2 at low temperatures of between about 300 and 700° C. for 2 to 8 hours and a ? of more than 0 and less than about 0.50, mixed two-phase compositions consisting of a spinel cathode and a layered oxide cathode, and coupling them with unmodified or surface modified graphite anodes in lithium ion cells.
