Abstract
The present invention provides an improved electrode material for a lithium secondary battery to provide a lithium secondary battery that is light in weight and has high energy density. Sulfur and a catalyst material such as active carbon, and the like, that reduces activation energy of an addition reaction of lithium to sulfur and allows the reaction to occur at not greater than 60° C., are included in the electrode material.
