    摘要: A lithium secondary battery that can suppress short circuits caused by the generation of dendrites from the negative electrode, that has high energy density, and that is excellent in charge and discharge-cycle performance. The lithium secondary battery comprises an electrolytic layer, a positive electrode, and a negative electrode that is made of a lithium-containing material. The electrolytic layer is made of an inorganic solid electrolyte. The positive electrode contains an organic high polymer. It is desirable that the electrolytic layer contain at least one type selected from the group consisting of oxygen, sulfur, nitrogen, sulfide, and oxynitride. It is also desirable that the organic electrolysis solution contained in the positive electrode have a lithium ion-conductivity lower than that of the inorganic solid electrolyte constituting the electrolytic layer.

    摘要: A composite solid electrolyte film is formed by dissolving a lithium salt such as lithium iodide in a mixture of a first solvent which is a cosolvent for the lithium salt and a binder polymer such as polyethylene oxide and a second solvent which is a solvent for the binder polymer and has poor solubility for the lithium salt. Reinforcing filler such as alumina particles are then added to form a suspension followed by the slow addition of binder polymer. The binder polymer does not agglomerate the alumina particles. The suspension is cast into a uniform film.
