The exfoliated graphite worm amount is in the range of 1% to 90% by weight and the amount of powder or coating is in the range of 99% to 10% by weight based on the total weight of exfoliated graphite worms and sulfur (sulfur compound or lithium polysulfide) combined. The cell exhibits an exceptionally high specific energy and a long cycle life.Type: ApplicationFiled: April 22, 2013Publication date: October 23, 2014Inventors: Yanbo Wang, Bor Z.

Patent number: 8841028Abstract: 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.Type: GrantFiled: October 23, 2013Date of Patent: September 23, 2014Assignee: Shin-Kobe Electric Machinery Co., Ltd.Inventors: Yoshikazu Hirose, Shinichi Sano, Katsura Mitani, Hiroyuki Wakatabe

Publication number: 20140272589Abstract: 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.Type: ApplicationFiled: October 1, 2012Publication date: September 18, 2014Applicant: NISSAN MOTOR CO., LTDInventors: Takashi Sanada, Wataru Ogihara, Manabu Watanabe, Atsushi Ito
