A conductive film includes a layer 1 formed by a conductive material 1 that includes a polymer material 1 containing any of (1) an amine and an epoxy resin (where the epoxy resin and the amine are mixed in a ratio of 1.0 or more in terms of the ratio of the number of active hydrogen atoms in the amine with respect to the number of functional groups in the epoxy resin), (2) a phenoxy resin and an epoxy resin, (3) a saturated hydrocarbon polymer having a hydroxyl group, and (4) a curable resin and an elastomer and conductive particles 1. The conductive film has excellent stability in an equilibrium potential environment in a negative electrode and low electric resistance per unit area in the thickness direction. A multilayer conductive film including the conductive film achieves excellent interlayer adhesion, and using them as a current collector enables the production of a battery satisfying both weight reduction and durability.

A collector for bipolar lithium ion secondary batteries comprises a first conductive layer that is obtained by adding a conductive filler to a base that contains an imide group-containing resin, and a second conductive layer that has a function of blocking lithium ions. The second conductive layer comprises a blocking resin layer that is obtained by adding a conductive filler to a base that contains a resin which contains no imide group, and a metal layer. This collector for bipolar lithium ion secondary batteries is used in such a manner that the first conductive layer is on the positive electrode active material layer side with respect to the second conductive layer.
摘要:
Bump electrodes (conductive members) bonded onto lands disposed at a peripheral portion side than terminals (bonding leads) electrically coupled to pads (electrode pads) of a microcomputer chip (semiconductor chip) are sealed with sealing resin (a sealing body). Thereafter, the sealing resin is ground (removed) partially such that a part of each of the bump electrodes is exposed. The step of protruding the part of each of the bump electrodes from a front surface of the sealing resin is performed, after the grinding step.

Disclosed is a passenger protection device (12) for a vehicle, which protects a passenger (Mn) sitting on a seat (11) when an external force (Fs) is applied to a side surface (16a) of a vehicle body (16). The passenger protection device has a side support (14). The side support is provided on the side portion of a seat back (46), and supports the upper body (Bu) of the passenger. The side support has a deformable portion (47). The deformable portion allows the side support to be deformed by an external force having a predetermined value or more.
