Abstract: The present disclosure relates to a solid electrolyte for a secondary battery which inhibits growth of lithium dendrite and is superior in cycle performance, a method for manufacturing the same, and a lithium secondary battery using the solid electrolyte. The solid electrolyte includes a polymer matrix, a lithium salt, a nitrile compound, and an additive ingredient, wherein the additive ingredient is at least one selected from a polymer or a copolymer polymerized from a monomer represented by the following Formula (1), and a polymer represented by the following Formula (2): where R1 is an olefin functional group having 2 to 6 carbon atoms; where R2 is a functional group having an ionic liquid structure such as —COOCH3, imidazole, pyrrole, piperidine, and a quaternary ammonium.

Abstract: The present invention relates to an anode material for lithium-ion batteries. The anode material for lithium-ion batteries is represented by the molecular formula: MxNyTizO(x+3y+4z)/2, where: 0?x?8, 1?y?8, and 1?z?8; M is an alkali metal selected from the group consisting of Li, Na, and K; and N is a group VA element selected from the group consisting of P, Sb, and Bi or a rare earth metal selected from the group consisting of Nd, Pm, Sm, Eu, Yb, and La. The anode material of the present invention has a delithiation potential of 0.8 to 1.2 V vs. Li+/Li, and has a better potential plateau, better cycle performance, and better output-input properties, than a titanium-based anode material.
