Embodiment Construction

[0041] exist Figure 1a The partition wall shown in cross-section in , comprises a disc 1 of porous ceramic material with a sealing edge portion 2 of glass, ceramic material, enamel material, glaze or similar material. The partition wall is shown in the form of a quadrilateral, but may also be circular or any other shape as regards its shape. The appropriate thickness of the ceramic thin plate is 0.3-3mm, preferably, the thickness is 0.75-1.0mm, and other dimensions are also conceivable.

[0042] Such as Figure 1a As shown, the sealing edge portion 2 surrounds the peripheral region of the perforated sheet, which structure provides advantageously superior properties for sealing and securing and is therefore preferred.

[0043] In a sintered porous sheet made of ceramic material, the sealing edge part is preferably a glass material which can be fixed well on the porous ceramic material and whose outer surface is suitable for fixing and fastening additional seals such as sealing...

Abstract

A partition wall for an electrode in a bipolar battery is comprised of a dimensional stable porous disc (1) of an electrically non-conductive material, the pores of which are filled with lead or a corresponding metal or an alloy thereof. The partition wall is distinguished by the porous disc at its peripheral region on at least one side being provided with an electrolyte-tight sealing edge portion (2) which is bound directly against the electrically non-conductive material in the porous disc, and that the material in the sealing edge portion includes any material from the group: glass, ceramic material, enamel, glazing, plastic or rubber. The invention also includes a bipolar electrode, a bipolar battery and a method for producing a partition wall.

Description

technical field [0001] The invention relates to an intermediate partition for a bipolar battery according to the preamble of claim 1 , a bipolar electrode comprising such a partition, a bipolar battery and a method of manufacturing such a partition. Background technique [0002] Bipolar batteries are already known, which are formed by arranging a plurality of bipolar electrodes connected in series. Typically, each group ends with a unipolar positive electrode with a current outlet at one end and a unipolar negative electrode with a current outlet at the other end. [0003] A separator is placed between each bipolar electrode. The purpose of placing the separator is to prevent the short circuit of the battery pack and hold a certain amount of electrolyte to ensure the passage of ions between the electrodes, and, in the case of the electrolyte participating in the unit cell reaction To ensure a certain capacity. In known bipolar batteries, a valve is provided in each unit ce...
