摘要:
The invention relates to a rechargeable electrochemical battery cell with a housing, a positive electrode (11), a negative electrode (10), and an electrolyte (9) which contains SO2 and a conductive salt of the active metal of the cell. At least one of the electrodes contains a binder selected from the group consisting of: binder A, which consists of a polymer that is made of monomer structural units of a conjugated carboxylic acid or the alkaline, alkaline earth, or ammonium salt of said conjugated carboxylic acid or a combination thereof, or binder B, which consists of a polymer that is based on monomer styrol and butadiene structural units, or a mixture of binders A and B.

Elektrochemische Batteriezelle mit einer negativen Elektrode, einem ein Leitsalz enthaltenden Elektrolyt und einer positiven Elektrode, wobei der Elektrolyt auf SO 2 basiert und der Zwischenraum zwischen der positiven Elektrode und der negativen Elektrode so ausgebildet ist, dass während des Ladens der Zelle an der negativen Elektrode abgeschiedene aktive Masse derartig in Kontakt zu der positiven Elektrode kommen kann, dass an deren Oberfläche lokal begrenzte Kurzschlussreaktionen stattfinden.
摘要:
The invention relates to an electrochemical battery cell with a negative electrode, an electrolyte containing a conducting salt, and with a positive electrode. The electrolyte is based on SO 2 , and the space between the positive electrode and the negative electrode is formed in such a manner that when the cell is being charged, the active material deposited on the negative electrode can come into contact with the positive electrode such that locally limited short-circuit reactions occur on the surface thereof.

Wasseraufbereitungsverfahren, insbesondere für die Gewinnung von Frischwasser aus Salzwasser mittels Membrandestillation. Im Vergleich zu vorbekannten Verfahren wird eine wesentliche Verminderung der Investitions- und Betriebskosten durch die Kombination folgender Maßnahmen erreicht: - Das aufzubereitende Wasser wird in einer Zuführungskammer (2) gehalten, deren Wand mindestens teilweise von einer hydrophoben wasserdampfdurchlässigen Membran (3) gebildet. - Parallel zu der hydrophoben Membran verläuft eine hydrophile Membran (5), die eine im Vergleich zu der hydrophoben Membran größere Dicke und geringere Wärmeleitung je Flächeneinheit hat. - Durch Pumpwirkung wird ein Dampfdruckunterschied zwischen dem aufzubereitenden Wasser und dem Frischwasser erzeugt, so daß die Membrandestillation durch den aus der Pumpwirkung resultierenden Dampfdruckunterschied angetrieben wird, wobei das Wasser in den Poren der hydrophilen Membran kondensiert.
摘要:
Disclosed is a water purification method, especially for obtaining fresh water from salt water by means of membrane distillation. Investment costs and operating expenses are substantially reduced compared with previously known methods by a combination of the following measures: the water that is to be purified is retained in a feeding chamber, the wall of which is formed at least in part by a hydrophobic steam-permeable membrane; a hydrophilic membrane that has a greater thickness and lower heat conductivity per unit area than the hydrophobic membrane extends parallel to the hydrophobic membrane; a difference in steam pressure is created between the water that is to be purified and the fresh water by means of a pumping action such that membrane distillation is driven by the difference in steam pressure created by the pump action, the water condensing in the pores of the hydrophilic membrane.
