摘要:
A lithium cell is described having a cathode structure made of a base material which conducts electrons and Li ions. The cathode structure includes a continuous substrate, which provides a continuous base area, starting from which a plurality of crosspieces extends. The crosspieces provide crosspiece surfaces, starting from which carrier structures extend. The carrier structures provide carrier surfaces on which active material is distributed. In addition, an accumulator is also described in which a plurality of lithium cells is stacked. A method for producing a lithium cell is also described.

A glass-ceramic composite material is described having a matrix that is at least from place to place of a glass type, and having a ceramic filler as well as a ceramic foil, a ceramic laminate or microhybrid using this composite material, the matrix containing lithium, silicon, aluminum and oxygen, and has at least from place to place a crystalline phase. In addition, a method is described for producing it, a glass having crystalline regions being melted from a starting mixture having 20 wt. % to 68 wt. % SiO2, 10 wt. % to 25 wt. % Al2O3, 5 wt. % to 20 wt. % Li2O, 0 wt. % to 35 wt. % B2O3, 0 wt. % to 10% P2O5, 0 wt. % to 10 wt. % Sb2O3 and 0 wt. % to 3 wt. % ZrO2 and converted into a glass powder, a ceramic filler, particularly powdered aluminum nitride, being then mixed in with the glass powder, and this powder mixture is finally sintered, especially after the addition of further components.

摘要:
A method for producing a piezoelectric actuator (8) with a multilayer structure of layers of a piezoelectric sheet (3, 4), and with inner electrodes disposed between them, is proposed, in which the individual layers are formed of two continuous strands (3, 4) of the piezoelectric sheet, and the two strands (3, 4) are wound over one another in the form of a double helix to form a hollow-cylindrical stack, thereby enclosing the inner electrode between them. The two strands (3, 5) are preferably guided over deflection rollers (5, 6, 7) in such a way that the overlays of the two strands (3, 4) on the already-wound stack are offset from one another by a predetermined angular amount.
摘要:
A sensor element, having a ceramic body made of a laminate having at least one ceramic foil and having a heating element embedded in the ceramic body. At least the longitudinal edges of the ceramic body have a chamfer. The heat source formed by the heating element lies in the direction of the bisector of an angle which is enclosed by a chamfer's edge lying closest to the heating element. The chamfer is formed in such a way that the angle enclosed by the large surface side edge, is larger than an angle enclosed by a narrow side edge.
摘要:
A sensor element, especially a temperature sensor (5) is proposed, having a sensitive area (11), whose electrical resistance changes under the influence of a temperature to which the sensitive area (11) is exposed. In this case, sensitive area (11) has a glass ceramic fusion (15) of a starting material containing at least one component which is furnished at least substantially with a surface metallization. The proposed temperature sensor (5) is especially suitable for use at temperatures in excess of 1000° C., at which it shows resistance characteristics like that of a platinum resistor.
摘要:
Rubber mixtures prepared from at least one styrene/butadiene rubber gel and at least one rubber which contains double bonds and optionally further fillers and rubber auxiliary substances are in particular suitable for the preparation of vulcanizates having unusually high damping at temperatures of from -20 to +20.degree. C. as well as unusually low damping at temperatures of from 40 to 80.degree. C. The rubber mixtures may therefore be used, for example, to manufacture vehicle tires which grip in the wet and have low rolling resistance.
