  • Patent number: 8841028
    Abstract: A lead acid storage battery composed of plates, the lead acid storage battery being obtained by packing an active material into a grid plate provided with a frame section having a quadrangular profile shape, and lateral grid strands and longitudinal grid strands that form a grid inside the frame section. The lateral grid strands are composed of thick lateral strands having a thickness equal to the thickness of the frame section, and thin lateral strands of smaller width and thickness than the thick strands, the longitudinal grid strands being composed of thick longitudinal strands that have a thickness that is less than thickness of the frame section, one end in the thickness direction being arranged in the same plane as one end of the frame section in the thickness direction, and thin longitudinal strands of smaller width and thickness than the thick longitudinal strands.

  • Publication number: 20140272589
    Abstract: A negative electrode active material for an electric device according to the present invention includes crystalline metal having a structure in which a size in a perpendicular direction to a crystal slip plane is 500 nm or less. More preferably, the size in the perpendicular direction to the crystal slip plane is controlled to become 100 nm or less. As described above, a thickness in an orientation of the slip plane is controlled to become sufficiently small, and accordingly, micronization of the crystalline metal is suppressed even if breakage occurs from the slip plane taken as a starting point. Hence, a deterioration of a cycle lifetime can be prevented by applying the negative electrode active material for an electric device, which is as described above, or a negative electrode using the same, to an electric device, for example, such as a lithium ion secondary battery.
