The present invention uses a magnesium-based alloy which is excellent in mechanical workability to be formed thinner than conventional alloys. The present invention provides a lithium secondary battery comprising an electrode assembly and a non-aqueous electrolyte, both accommodated in a metal jacket, wherein the metal jacket is made of a magnesium-based alloy containing lithium in an amount of 7 to 20% by weight; and a metal layer or an insulating layer for preventing corrosion of the metal jacket is formed integrally with the metal jacket on the inner wall thereof.

Lithium secondary battery and method of manufacturing the same

A mixture of a polyolefin-based resin and a solvent is heated to a temperature at which at least part of the polyolefin-based resin melts to produce a viscous, gel-like adhesive solution. A mixture of the adhesive solution, an active material, and a conductive material is kneaded to produce a paste-form mixture, and a collector is coated with this paste-form mixture to form a mixture layer. The collector with the mixture layer formed thereon is then heated and dried, after which it is press-molded to a specific thickness and cut to a specific size to produce electrode plates.
