摘要: A non-aqueous electrolyte battery of the present invention includes a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte, and the separator contains polyphenylenesulfide fibers, aramid fibers, and cellulose fibers at ratios of 50 to 85 mass %, 10 to 30 mass %, and 5 to 35 mass %, respectively. This makes it possible to provide a non-aqueous electrolyte battery with characteristics that are less likely to deteriorate under a high-temperature environment and in which few defects occur during assembly.

摘要: A non-aqueous electrolyte primary battery of the present invention includes: a negative electrode; a positive electrode; a separator; and a non-aqueous electrolyte. The negative electrode contains metallic lithium or a lithium alloy. The positive electrode contains a manganese oxide or a lithium-containing manganese oxide with a lithium content of 3.5% by mass or less. The non-aqueous electrolyte contains a phosphoric acid compound or a boric acid compound having in its molecule a group represented by General Formula (1) below, and the content of the phosphoric acid compound or the boric acid compound in the non-aqueous electrolyte is 8% by mass or less: where X is Si, Ge or Sn; R1, R2 and R3 independently represent an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, or an aryl group having 6 to 10 carbon atoms; and some or all of hydrogen atoms may be substituted with a fluorine atom.

摘要: Provided is a tire pressure detection system that can be operated stably for a long period of time by using, as a power source, a secondary battery having little characteristic deterioration under a high temperature environment, e.g. in a situation in which the battery is maintained for a long period of time in a fully charged state under a high temperature environment, while having excellent low temperature characteristics. A tire pressure detection system 1 includes: an air pressure detection device 10 that detects an air pressure inside a tire; and a secondary battery 20 that supplies power to the air pressure detection device 10. The secondary battery 20 is a lithium secondary battery that includes a negative electrode containing a lithium alloy as an active material and a positive electrode.
