摘要:
A rechargeable lithium ion battery with high power density comprises a positive electrode; a negative electrode; and a non-aqueous electrolytic solution, in which the positive electrode includes a active material layer containing a positive electrode active material with the particle diameter of 5 μm or less and having the thickness at a range of 20 to 80 μm. Another rechargeable lithium ion battery with high power density comprises a positive electrode; a negative electrode; and a non-aqueous electrolytic solution, in which the positive electrode has two active material layers, each of which contains a positive electrode active material with a different diameter and has the thickness at a range of 20 to 30 μm.

A vehicle (V) includes a battery enclosure (152) enclosing a battery system (B). Each battery (Bn) includes a cell (1) that comprises a rolled lamination (LM) of a positive sheet electrode (11) having layers (13) of positive-pole-oriented active substance coated on both side of a charge collecting sheet (12), a negative sheet electrode (21) having layers (23) of negative-pole-oriented active substance coated on both sides of another charge collecting sheet (22), and electrolyte-containing separator (31) between the layers of active substances. The batter further includes a cell enclosure (2) totally enclosing the cell. A gas effluent system (100) for the battery system comprises a gas release system (RSn) for generated gas in the cell of each battery to be released outside the cell enclosure, and a gas discharge system (DS) for released gas to be discharged outside the battery enclosure. The gas release system comprises gas release circuitry including a network (NT) of blanks (Cp: P=1,2, . . . , q, . . . ) formed in the lamination, e.g. pointed or zoned blanks (14, 14A, 15, 16, 17, 18) formed in the layer(s) of active substance(s) and/or the charge collecting electrode(s), a blank space (Sp) between the cell and the cell enclosure, and release valve (4a, 6a). The gas discharge system comprises a gas discharge circuit (DC) communicable with the gas release circuitry, and provided as a draft controllable ducting (150, 170) defined between a floor panel (153) of vehicle body (VB) and a wall of the battery enclosure.
