摘要： Disclosed is a flat-shaped battery including: a power generation element including a positive electrode, a negative electrode, a separator, and an electrolyte; a cylindrical case formed of a conductor, housing the power generation element, and having a circular bottom and a circular opening; a sealing plate formed of a conductor and closing the opening; an insulating member interposed between the case and the sealing plate; and a plate-shaped current collector disposed between the case and the positive electrode. The current collector is welded to the case and is in contact with the positive electrode. A welding point where the current collector is welded to the bottom is set so as to allow contact between the positive electrode and a center portion of the current collector to be maintained when the case is deformed such that a center portion of the bottom is displaced outward of the case.

摘要： An electrochemical cell comprising:
a non-aqueous electrolyte comprising an organic solvent,
electrodes being wound together into a jellyroll electrode assembly, wherein the cathode assembly comprises a metallic cathode current collector having two major surfaces and a cathode coating comprising iron disulfide disposed on at least one of the two major surfaces and the anode comprising metallic lithium alloyed with less than 1.0 percent by weight of aluminum and electrical contact between the electrodes and other cell components is made by means of pressure or fastening,

wherein the anode to cathode input ratio is less than or equal to 1.0, wherein the anode to cathode ratio is determined as follows:
- anode to cathode input ratio = anode capacity per 2.54 cm [linear inch]/cathode capacity per 2.54 cm [linear inch]

wherein
- the anode capacity per 2.54 cm [linear inch] = (foil thickness) x (interfacial electrode width) x 2.54 cm [1 linear inch] x (density of lithium foil at 20 °C x (lithium energy density, 2861.7 mAh/g), and
- the cathode capacity per 2.54 cm [linear inch] = (final cathode coating thickness) x (interfacial electrode width) x 2.54 cm [1inch] x (cathode dry mix density) x (final cathode packing percentage) x (dry weight percent FeS 2 ) x (percent purity FeS 2 ) x (FeS 2 energy density, 893.58 mAh/g).
