摘要:
A multilayer battery cell comprises an ion-conductive separator film. A positive electrode layer is disposed on one surface of the separator film. A negative electrode layer is disposed on the other surface of the separator film. A first conductive layer is disposed on the positive electrode layer and electrically connected to the same. A second conductive layer is disposed on the negative electrode layer and electrically connected to the same. The positive and negative electrode layers and the first and second conductive layers are each produced by employing a spraying process.

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.

摘要:
The disclosure relates to a novel polymer which is made up of repeating units of N,N,N'N'-tetrapheny-p-phenylenediamine. This polymer is thermoplastic and is soluble in industrially usable organic solvents. The polymer acquires high conductivity by doping with an electron acceptor. The polymer becomes insoluble in organic solvents when it is once doped with an electron acceptor and then dedoped, so that the polymer can be used as an active electrode material in electrolytic devices using an organic solvent. The polymer has electrochromic properties and undergoes two-stage oxidation and two-stage reduction to assume three differently stable states. The polymer exhibits pale yellow color in its reduced state, green color in the first-stage oxidized state and dark blue color in the second-stage oxidized state.
