Abstract

A non-aqueous electrolyte type secondary battery comprises a negative electrode capable of occluding and releasing lithium, a positive electrode capable of occluding and releasing lithium, a non-aqueous electrolyte which contains a lithium salt, and a container for accommodating the negative electrode, the positive electrode, and the electrolyte. The negative electrode is formed by pressing a foam metal or a fibrous sintered metal which contains nickel as a principal component thereof and which is filled with a mixture of a binder and a carbon material capable of occluding and releasing lithium. The negative electrode has a thickness of not less than 0.1 mm and a porosity of 20 to 50%.
