Abstract: A cathode for Li—S battery includes a current collector and a cathode composite layer disposed on the current collector. The cathode composite layer includes (i) a porous carbon layer, (ii) a first binder that is at least partially in contact with the porous carbon layer and (iii) elemental sulfur. A second binder is at least partially disposed between the current collector and the cathode composite layer. A Li—S battery also is contemplated, as are methods of fabricating the cathode and the battery.

Abstract: A drawn portion having a shape protruding from a side face to a space inside a housing is provided at an end to which a rear surface cover is fastened of the side face. On a side to which the rear surface cover is fastened of the drawn portion, a bent portion having a shape bent toward a space outside the housing is provided. A screw receiving portion including a screw hole includes a first receiving surface, which is a flat surface portion on an end of the bent portion, and a second receiving surface having a shape protruding from a base of the bent portion.

Abstract: A method for producing a positive electrode material for a nonaqueous secondary battery includes the steps of mixing a compound containing lithium, a compound containing nickel and BaTiO3 to form a mixed material; and sintering the mixed material to form a lithium transition metal composite oxide.

Abstract: A method for producing an electrode for a non-aqueous secondary battery is provided, the method includes: mixing a compound containing lithium, a compound containing nickel, and barium titanate to obtain a mixture; heat-treating the mixture to obtain a first composition containing a lithium-transition metal composite oxide; preparing an electrode composition containing the first composition, a conductive aid, and a binder; and applying and compressing the electrode composition on a current collector to form an active material layer with a density of from 2.4 g/cm3 to 3.6 g/cm3 on the current collector.
