  • Patent number: 12255318
    Abstract: The non-aqueous electrolyte battery is excellent in high-temperature storage characteristics and load characteristics at low temperature. A non-aqueous electrolyte battery of the present invention includes a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte. The negative electrode includes a lithium layer, a lithium-aluminum alloy layer formed on a surface of the lithium layer, and a carbon layer on the lithium-aluminum alloy layer. The non-aqueous electrolyte battery of the present invention can be manufactured by a method for manufacturing a non-aqueous electrolyte battery that includes providing an aluminum layer on the surface of the lithium layer to obtain a laminate, forming the carbon layer on a surface of the aluminum layer to obtain a laminate for a negative electrode, and causing the lithium layer and the aluminum layer of the laminate for a negative electrode to react with each other to form the lithium-aluminum alloy layer.

  • Publication number: 20130330580
    Abstract: A sealed battery with a cleavage groove is provided. A cleavage groove (41) is provided on a flat section (13) of the battery case (2) to form a cleavage line intersecting a ridge line (L) formed on the flat section of the battery case when the battery case swells up due to an increase in internal pressure. The cleavage line is, as viewed in a side view, a curved line made up of a first curved segment (42) curved to protrude in one direction and a second curved segment (43) curved to protrude in a direction forming an angle of 90 degrees or larger with the direction in which the first curved segment protrudes, the first and second curved segments being connected with each other. At least one of the first curved segment and the second curved segment intersects the ridge line.
