    Abstract: A current interruption mechanism for prismatic secondary battery includes a tubular conductive member electrically connected to a positive electrode external terminal, an inversion plate, and a positive electrode collector connected to the inversion plate. The positive electrode collector has a first region that is parallel to a sealing body and a second region that is connected to a positive electrode plate. The boundaries between the first and second regions are disposed further outward than the inner surface of the tubular conductive member, and at least one of the edge portions, other than the boundaries between the first region and second region, is located further outward than the inner surface of the tubular portion of the conductive member. The current interruption mechanism is unlikely to be damaged even if the battery is subjected to shock due to vibration, falling, etc.

    Abstract: A nonaqueous electrolyte secondary battery includes a positive electrode plate including a positive electrode core and a positive electrode mixture layer formed thereon; a negative electrode plate including a negative electrode core and a negative electrode mixture layer formed thereon; a wound electrode assembly in which the positive electrode plate and the negative electrode plate are wound with a separator therebetween so as to be insulated from each other; a nonaqueous electrolyte solution; a pressure-responsive current interruption mechanism electrically connected to at least one of the positive electrode plate and the negative electrode plate; and an outer casing. Excess electrolyte solution is present outside the electrode assembly in the outer casing. The liquid level of the excess electrolyte solution is at such a height that the excess electrolyte solution does not come into contact with a component of the current interruption mechanism when the outer casing is placed horizontally.

    Abstract: A groove is formed in a ring shape and a ring-shaped convexity is formed on the periphery of a through-hole of a positive electrode terminal plate. An upper end side of a crimping part of a positive electrode exterior terminal is inserted through the through-hole of the positive electrode terminal plate and crimped, and welded spots are formed by irradiation with high-energy beams between a distal end side of the crimping part and the convexity. The mechanical and electrical connection of an exterior terminal and a terminal plate to the crimping part through welding with high-energy beams makes it possible to provide a prismatic secondary battery of enhanced reliability in which cracking is less likely to occur in the welded spots, the coupling strength between the exterior terminal and the terminal plate is increased, and fluctuations in the internal resistance are curbed.

    Abstract: A nonaqueous electrolyte secondary battery according to an embodiment of the present invention includes an electrode assembly, a nonaqueous electrolyte, and a container. The electrode assembly includes a positive electrode, a negative electrode, and a separator. The negative electrode is opposed to the positive electrode. The separator is disposed between the positive electrode and the negative electrode. The container houses the electrode assembly and the nonaqueous electrolyte. The container has a positive electrode terminal and a negative electrode terminal. The positive electrode terminal is electrically connected to the positive electrode. The negative electrode terminal is electrically connected to the negative electrode. The container further includes a short-circuiting mechanism that short-circuits the positive electrode terminal and the negative electrode terminal if the internal pressure rises. The nonaqueous electrolyte contains lithium bis(oxalato)borate (LiBOB).

    Abstract: A crimped portion of a positive electrode external terminal is crimped on its upper end side to be electrically connected to a positive electrode terminal plate. This crimped portion is welded to the positive electrode terminal plate by applying high energy beams. The negative electrode side has a configuration similar to that of the positive electrode side. The contact area between the positive electrode terminal plate and the crimped portion of the positive electrode external terminal is set smaller than the corresponding contact area on the negative electrode side, and the volume of the crimped portion of the positive electrode external terminal is set larger than that of the corresponding crimped portion on the negative electrode side. Thus, a prismatic secondary battery is provided that shows strong joining strength between the external terminal and the terminal plate, suppressed internal resistance variations, and improved reliability.
