An apparatus (10) to carry out a process for the in situ generation of agglomerate structures and the controlled influencing of the resulting agglomerates contains a closed flow duct (12) through which is directed an aerosol containing particles (14). For the purpose of the bipolar charging of the aerosol, at least one electrode pair (20, 22) is arranged in the flow duct (12), the electrode (20) being wired, so as to be ungrounded, to the negative pole of a current source, the strength of which is sufficient to produce a corona discharge between the electrodes (20 and 22). The electrodes (20 and 22) of each electrode pair are designed to be needle-shaped and are arranged to be insulated with respect to the flow duct walls, such that their tips (26) are disposed opposite each other. By use of the apparatus (10), it is possible to charge the aerosol which is directed through the flow duct (12) at least virtually symmetrically bipolarly, without any substantial particle deposition in the region of the electrodes (20) and (22) or in the flow duct (12). Thus, specific agglomeration, with regard to at least one of the parameters concentration, structure or dimension, of the particles can be obtained in the flow duct during flow therethrough.

摘要:
A protective device for galvanic cells (201, 202, 301, 302) which are interconnected via contact elements (205, 207, 209, 212, 405, 409, 406, 407, 506, 507, 509, 606, 607, 706, 707, 709, 805, 806, 807, 809) that are suitably connected to pole connections (203, 204, 503, 504) of said cells to give a battery can be associated with individual cells of a battery. The protective device has an activation device (1008, 1108, 1208, 1011, 1111) for activation. When the protective device is activated, the protective device bridges the cell associated therewith by changing the interconnection and thus removes it from the electrical functioning of the battery assembly. In the activation device, preferably an electroconductive or insulating component made of a shape memory material brings about the change of the interconnection by changing the shape of said component as soon as and/or as long as the temperature of said component lies outside a defined temperature range.

摘要:
A profile strip to border an electrochemical energy storage device having at least one, essentially, longitudinally extending first recess, which is bordered by a first arm and a second arm. The first and the second arm are made such that they are attachable to opposite sides of an boundary area of the electrochemical energy storage device, and at least partially connected to each other with a backside part. In a method of producing such a profile strip for an electrochemical energy storage device, at least one first recess is inserted into the profile strip by a suitable method, and the profile strip is converted in said first recess from a first, stretched, state into a second, angled, state. The corner resulting from bending may have a connection by force-fit or by material engagement.
