摘要:
A long-life battery whose properties do not deteriorate after charge-discharges cycles is provided. A non-aqueous electrolyte secondary battery includes a cathode, an anode, and a non-aqueous electrolytic solution containing an electrolyte. At least one of the cathode and the anode includes a binder. The binder includes a layer having electron conductivity on a surface thereof. The binder improves the contact property between particles of the active materials of the battery and the conductivity in the electrode without impairing the binding property of the binder. Preferably, the binder includes a metal on the surface thereof and the metal does not form an alloy with lithium to further improve the lifetime of the battery.

An electrode for a lithium-ion secondary battery includes a collector of copper or the like, an electrode material layer being form on one surface and both surfaces of the collector and including an active material and a binder, and a binder-rich layer being formed in a dot shape or a stripe shape with a predetermined interval in the interface between the collector and the electrode material layer and having a binder concentration higher than that of the electrode material layer. Accordingly, a concentration gradient of the binder is provided to the surface of the collector. By arranging the binder-rich layer at a predetermined interval, it is possible to improve the adhesiveness between the collector and the electrode material layer due to an anchor effect and to guarantee conductivity between the collector and the electrode material layer.

Disclosed are an electrode for a lithium secondary battery which includes a metal substrate and a plated layer arranged on the metal substrate and bearing active material particles and resin particles embedded therein, in which a part of the active material particles and the resin particles has a protruding portion beyond the plated layer; and a lithium secondary battery using the electrode. The electrode helps the lithium secondary battery to be resistant to deterioration and property degradation at high temperature and allows the battery to have high input-output performance and to be suitable typically for hybrid electric vehicles.

A composite material structure that can be made lighter in weight is provided, with the stress concentration at peripheral edge regions around holes being taken into consideration. A wing (1) that is a composite material structure is of a composite material that extends in one direction, has access holes (5) formed therein, and is made of fiber reinforced plastic. A lower surface outer plate (3) of the wing (1) is subjected to a tensile load in the longitudinal direction. The longitudinal tensile stiffness of peripheral edge regions (3a) around the access holes (5) is lower than the longitudinal tensile stiffness of other regions (3b) surrounding the peripheral edge regions (3a).

Of a sensing part and a mounting part of an oil level sensor mounted to a sensor mounting opening at a bottom portion of an oil pan of an engine, an undersurface of the mounting part exposed to the outside of the oil pan is located above the lowest part of the oil pan by a distance, and the mounting part is disposed in a recessed part formed on an undersurface of the oil pan and is covered with a cover plate. Therefore, the weight of the engine does not directly act on the mounting part of the oil level sensor when the engine is directly placed on a floor surface. Further, even in a state in which the engine is mounted on a vehicle body, the mounting part of the oil level sensor can be also effectively protected at the time of colliding with a flying stone, riding on a curbstone, jacking up or the like.

摘要:
A thermal shield structure with ceramic blocks for protecting high-temperature-exposed wall surface in which wedge-shaped supporting members and wedge-shaped members to be supported, respectively provided on the wall surface and ceramics blocks as a plurality of pairs of wedge-groove couplings, are engaged with each other to cover the wall surface with the ceramic blocks. In accordance with the invention, a gap small enough to prevent mutual disengagement of each pair of the wedge-shaped supporting member and the wedge-shaped supported member is provided therebetween to permit movement of the ceramic blocks towards the wall surface. A passage for an air supply into each wedge-shaped supporting member is provided so that each wedge-shaped supported member is urged by the pressure of supplied air to be retained in the wedge-shaped supporting member, whereby the ceramic blocks are held on the wall surface.
