  • Publication number: 20210320307
    Abstract: A lithium primary cell includes an electrode group and a non-aqueous electrolytic solution. The electrode group includes a positive electrode, a negative electrode, and a separator, in which the positive electrode and the negative electrode are wound with the separator interposed therebetween. In the electrode group, an area where the positive electrode and the negative electrode face each other is 250 cm2 or more and 350 cm2 or less. The positive electrode includes a positive electrode mixture including manganese dioxide and a boron compound. The negative electrode includes lithium metal or a lithium alloy. The non-aqueous electrolytic solution includes ethylene carbonate. A content of the boron compound in the positive electrode is 0.5 parts by mass or more and 2 parts by mass or less in terms of boron with respect to 100 parts by mass of the positive electrode mixture.

  • Patent number: 9653215
    Abstract: A solid electrolytic capacitor comprises a positive electrode, a dielectric layer, a silane coupling layer, a conductive polymer layer, and a negative electrode layer. The dielectric layer is provided on the positive electrode. The silane coupling layer is provided on the dielectric layer. The conductive polymer layer is provided on the silane coupling layer. The negative electrode layer is provided on the conductive polymer layer. The silane coupling layer comprises a first silane coupling layer and a second silane coupling layer. The first silane coupling layer covers a part of a surface of the dielectric layer facing the conductive polymer layer. The second silane coupling layer covers at least a part of a portion exposed from the first silane coupling layer on the surface of the dielectric layer facing the conductive polymer layer.
