摘要:
A hollow body with first and second open ends is spanned between a dashboard and an instrument panel in such a manner that the first open end is open to a fresh air inlet opening formed in the dashboard and the second open end is supported by the instrument panel. A guide member is mounted on the mouth of the first open end of the hollow body to aid in locating the first open end during the connection of the same to the dashboard while allowing air to flow thereover to enter the hollow body.

Charge-discharge cycle performance is improved in a lithium secondary battery that adopts a thin film made of silicon or a silicon alloy as its negative electrode active material and has a wound electrode structure. The lithium secondary battery includes: a negative electrode having a current collector and a thin film made of silicon or a silicon alloy as a negative electrode active material, the thin film provided on the current collector; a positive electrode; a separator; the positive and negative electrodes being overlapped with the separator interposed therebetween, and the positive and negative electrodes and the separator being wound around to form an electrode assembly; a non-aqueous electrolyte; and a battery case accommodating the electrode assembly. The ratio of theoretical capacity per unit area of the negative electrode to charge capacity per unit area of the positive electrode is within the range of from 1.9 to 4.4.

A nonaqueous secondary battery 10 of the invention has an active material compound layer 14 deposed over at least one face of a collector 12 made of metal foil and is equipped with a positive electrode 11 having a portion 13 in a part of which metal is exposed. The positive electrode 11 together with the exposed-metal portion 13 faces a negative electrode 17 through an interposed separator 23, and on that part of the exposed-metal portion 13 that faces the negative electrode 17 through the interposed separator 23 there is formed a protective layer 16 made of a material whose electronic conductivity is lower than that of the metal and which moreover is non-insulative. With such nonaqueous secondary battery 10, should part of an electrode pierce the separator and contact with the other electrode, the battery will be gently discharged, thereby averting abnormal heat generation by the battery and additionally enabling the battery's abnormality to be sensed by the equipment via the fall in battery voltage. Thus, there is provided a nonaqueous secondary battery of excellent safety that can prevent abnormal heat generation due to a short circuit caused by burr, powder or the like piercing the separator.

摘要:
A lithium secondary battery employing as its negative electrode active material a material that increases in volume by alloying with lithium during charge achieves high discharge capacity and good cycle performance. The lithium secondary battery includes a negative electrode having a negative electrode active material (2) and a negative electrode current collector, a positive electrode having a positive electrode active material (1) and a positive electrode current collector (3), and a non-aqueous electrolyte. The negative electrode active material (2) is a material that increases in volume by alloying with lithium during charge. The negative electrode active material (1) is arranged so as to be on, and in contact with, the negative electrode current collector. The negative electrode active material (2) contains, when in an end-of-discharge condition, 8% or more of lithium with respect to the total capacity of the negative electrode active material (2) as measured when it does not contain lithium.
