  • Patent number: 8530110
    Abstract: A lithium-ion secondary battery separator has a porous structure formed by laminating a second polymer layer, a first polymer layer, and a second polymer layer in sequence. The second polymer layer has a melting point lower than that of the first polymer layer. The second polymer layer has a higher molecular part formed on a side in contact with the first polymer layer and a lower molecular part formed on a side farther from the first polymer layer than is the higher molecular part. The higher and lower molecular parts have a weight-average molecular weight ratio (higher molecular part/lower molecular part) of 4 to 19 therebetween.

  • Patent number: 8343669
    Abstract: An electrochemical device comprises an electrode matrix including a multilayer structure composed of a positive electrode, a negative electrode, and a first separator, and first and second dummy electrodes electrically connected to the positive and negative electrodes, respectively. The first and second dummy electrodes have respective opposing parts opposing each other through a second separator at an outer peripheral part of the electrode matrix. One or each of the first and second dummy electrodes has a resistance control layer at least on a side where the opposing parts oppose each other. The resistance control layer has such a resistance value that an estimated internal short circuit current between the first and second dummy electrodes is equivalent to 0.09 C to 1.00 C. The first and second dummy electrodes are adapted to short-circuit each other at a lower temperature than the positive and negative electrodes do.

  • Publication number: 20100075224
    Abstract: An electrode has a current collector having a plurality of through holes, and active material layers provided on both sides of the current collector, the current collector has projections extending on the top side or on the back side of the current collector from respective edges of the through holes, and an angle between each of the projections and a surface direction of the current collector is in the range of 30 to 80°. Because of the configuration wherein the projections are surrounded by the active material layers, a physical anchor effect is achieved so as to provide high adhesion. Since the projections are inclined relative to the surface direction of the current collector, the distance becomes shorter between the current collector including the projections and an active material, which was located apart from the projections in the case where the projections extended perpendicularly to the surface direction of the current collector.
