NON-AQUEOUS LITHIUM-TYPE POWER STORAGE ELEMENT

摘要

A non-aqueous lithium-type power storage element comprising an electrode laminate body and a non-aqueous electrolyte being housed in an external body, the electrode laminate body having a negative electrode body, a positive electrode body and a separator. The negative electrode body has a negative current collector and a negative electrode active material layer that includes a negative electrode active material and that is provided to one or both surfaces of the negative current collector. The negative electrode active material includes a carbon material that can occlude and release lithium ions. The positive electrode body has a positive current collector and a positive electrode active material layer that includes a positive electrode active material and that is provided to one or both surfaces of the positive current collector. The positive electrode active material includes activated carbon. The non-aqueous electrolyte contains, based on the total amount of the non-aqueous electrolyte, 0.5 mol/L or more of a lithium salt, and the negative electrode active material layer includes, per unit weight of the negative electrode active material, 2.6 x 10-6-2, 000 x 10 -6 mol/g of a specific sulfur compound.
