Abstract:
PURPOSE: An electrolyte for a lithium secondary battery is provided to prevent oxidation of electrolyte on the surface of a positive electrode, and to prevent decomposition of electrolyte in high temperature condition. CONSTITUTION: An electrolyte for a lithium secondary battery comprises a lithium salt, a non-aqueous organic solvent, and additives consisting of one or more compounds selected from purinone or purinone derivatives. The comprised amount of the derivative is 0.005-5 weight%. A lithium secondary battery comprises a positive electrode comprising a positive electrode active material(22) capable of inserting or eliminating lithium, a negative electrode comprising a negative electrode active material capable of inserting or eliminating lithium, and electrolyte(28) filling the positive electrode and the negative electrode.

PURPOSE: An electrode for a super capacitor, the super capacitor using the same, and a manufacturing method thereof are provided to increase the capacity of the super capacitor by adopting the electrode for the supper capacitor, which includes a metal nano structure. CONSTITUTION: An electrode for a super capacitor includes a conductive substrate, a metal nano structure, and a metal oxide. The metal nano structure is formed on the conductive substrate and is a porous metal nano bar or porous metal nano tube. The metal nano structure includes one or more among Au, Ag, Ni, Cu, Pt, Mn, Ru, and Li. The metal oxide is coated on the metal nano structure.
Abstract:
PURPOSE: A battery and a battery pack including thereof are provided to easily collect the electric current while maintaining the heat emission efficiency, using the battery including a cooling hole. CONSTITUTION: A battery comprises the following: an electrode assembly; a main body unit(100) including a cooling hole(H1) formed to a first direction; and a positive electrode terminal(50a) and a negative electrode terminal(50b) formed to a second direction. The first direction and the second direction perpendicularly cross each other. The cooling hole penetrates the main body unit, while the positive and the negative electrode terminals are extended to the upper side of the main body unit. The main body unit includes an internal frame which is surrounded by the electrode assembly.
