Description

Behälter aus porösem Stoff, z. B. Pappe, für galvanische Trockenbatterien Die Erfindung bezieht sich auf einen Behälter aus porösem Stoff, z. B. Pappe, für galvanische Elemente, vorzugsweise Trockenbatterien. Einer der wichtigsten, die Leistung einer Trockenbatterie bestimmenden Faktoren ist der sog. Wasserhaushalt, d. h. die Erhaltung derjenigen Elektrolytmenge, welche den Batterien bei der Fabrikation hinzugegeben wird. Alle Trockenbatterien, insbesondere diejenigen mit Luftsauerstoffdepolarisation, haben die natürliche Neigung, schon bei normaler Luftfeuchtigkeit, insbesondere aber in trockener Atmosphäre dauernd Wasser in Form von Dampf an die Umgebung abzugeben.Container made of porous material, e.g. B. cardboard, for galvanic dry batteries The invention relates to a container made of porous material, e.g. B. cardboard, for galvanic elements, preferably dry batteries. One of the most important that The factors that determine the performance of a dry battery are the so-called water balance, d. H. the maintenance of the amount of electrolyte that the batteries have in their manufacture is added. All dry batteries, especially those with atmospheric oxygen depolarization, have the natural tendency, especially at normal humidity but in a dry atmosphere to continuously release water into the environment in the form of steam.

Dieser Nachteil wird bei dem Behälter gemäß der Erfindung mittels eines aus einer dünnen Metallfolie bestehenden Überzuges vermieden. Damit wird gleichzeitig auch das sonst auftretende Auskristallisieren und Schrumpfen des Elektrolyten verhindert und die Lebensdauer der Batterien wesentlich verlängert.This disadvantage is by means of the container according to the invention a coating consisting of a thin metal foil avoided. This is at the same time also prevents the electrolyte from crystallizing out and shrinking, which would otherwise occur and significantly extends the life of the batteries.

Wie Versuche gezeigt haben, ist es besonders günstig, Metallfolien für den- Überzug zu verwenden. Erfindungsgemäß kann man Folien aus Zink oder aus Aluminium benutzen. Dabei genügt schon eine Folie in einer Dicke von etwa zo lt. Erfindungsgemäß wird die dünne Metallfolie unter Verwendung einer Zwischenlage, z. B. aus Papier, aufgeklebt bzw. kaschiert. Man kann aber auch die Metallfolie zwischen zwei den Behälter bildende Papplagen einbetten. Zum Schutze kann man die Metallfolie mit einem Überzug aus Kunststoff versehen. Man hat bereits vorgeschlagen, verhältnismäßig undurchlässige Kunststoffolie zu den obengenannten Zwecken als Überzug auf Batteriebehältern zu verwenden, Hierbei hat sich aber der Nachteil ergeben, daß die Kunststoffolie gegen die beim Aufbringen der Vergußmasse auftretenden höheren Temperaturen nicht beständig genug ist und sich von der Kartonunterlage ablöst. Dieser Nachteil tritt bei der Verwendung einer Metallfolie gemäß der Erfindung nicht auf. Außerdem ist die Wasserundurchlässigkeit der Metallfolie noch erheblich größer als diejenige einer Kunststoffolie, wie sich dies aus den nachstehend aufgeführten Versuchsergebnissen ergibt Wasserdampfdurchlässigkeit verschiedener Stoffe Bezeichaung des Materials Wasserdampfdurchlässigkeit g Wasser pro dm2 h Normalkarton .................................. 7,10 - 7,30 X 1o-2 g Normalkarton mit Kunstlack überzogen .......... etwa 1,9 X t0-2 g Kunststoffolie (3o ,u) . . . . . . . . . . . . . . . . . . . . . . . . . . . - 0,4 - 0,5 X =o 2 g Zinkfolie (to /z) ................................ - 0,095 - o,11 X I0-2 g Aluminiumfolie (to ,u) . . . . . . . . . . . . . . . . . . . . . . . . . : - 0,025 - 0,035 X to 2 g. As tests have shown, it is particularly advantageous to use metal foils for the coating. According to the invention, foils made of zinc or aluminum can be used. A film with a thickness of about zo lt is sufficient. According to the invention, the thin metal film is made using an intermediate layer, e.g. B. made of paper, glued or laminated. But you can also embed the metal foil between two cardboard layers forming the container. For protection, the metal foil can be provided with a plastic coating. It has already been proposed to use relatively impermeable plastic film for the above-mentioned purposes as a coating on battery containers, but this has the disadvantage that the plastic film is not resistant enough to the higher temperatures occurring when the potting compound is applied and detaches itself from the cardboard base. This disadvantage does not arise when using a metal foil according to the invention. In addition, the water impermeability of the metal foil is considerably greater than that of a plastic foil, as can be seen from the test results listed below Water vapor permeability of various substances Name of the material water vapor permeability g water per dm2 h Normal cardboard box .................................. 7.10 - 7.30 X 1o-2 g Normal cardboard covered with synthetic varnish .......... approx. 1.9 X t0-2 g Plastic film (3o, u). . . . . . . . . . . . . . . . . . . . . . . . . . . - 0.4 - 0.5 X = o 2 g Zinc foil (to / z) ................................ - 0.095 - o, 11 X I0-2 g Aluminum foil (to, u). . . . . . . . . . . . . . . . . . . . . . . . . : - 0.025 - 0.035 X to 2 g.
