Problems solved by technology

Although the gas transport (oxygen transport) in the cell of the accumulator can thus be increased, due to the worsening of the contact between active mass and gel, cracks in the immediate surroundings of the active mass lead to an increase in the internal resistance of the cell and thus lead to an adverse effect on the power of the battery

Embodiment Construction

[0016] The device according to the invention for carrying out the method has, in addition to corresponding electrical connections and a power supply suitable for applying the required forming voltage, a filling head 1 with at least one each for gel, acid and flushing The injection port 19 of the medium. Furthermore, the filling head 1 has a mixing device 20 for static mixing at least the gelling agent and the acid liquid. The filling head also has a filling finger 21 which is advantageously adapted to the accumulator to be filled and which is exchangeably mounted on it for the purpose of making the filling head maneuverable. In addition, the device has flow meters for the gelling agent and the acid to be added, by means of which a precise mixing ratio can be produced as prescribed by means of a control device.

[0017] In addition, the device has an inlet line for the flushing medium 2 on the filling head, with which the residual gel in the gel delivery line 11.1 / +11.2 can be...

Abstract

Electrolyte is placed into a cell in a fluid state. Solidification and formation of the active material are performed at the same time in the cell. The electrolyte is solidified into a gel form. The gel comprises a sol and an acid. Independent claims are included for: an apparatus for carrying out the method, and for a filling head.

Description

technical field [0001] The invention relates to a method and a device for producing an accumulator with a fixed electrolyte. Background technique [0002] Accumulators with fixed electrolytes have been known since 1950. The advantages of this type of battery are its ease of maintenance and reliability against leakage of the electrolyte in the battery cell. To immobilize the electrolyte, it is known to coagulate it in the form of a gel and to hold it in place in the cell of the battery by means of a microstructured fiber web. [0003] The representative fixed gel storage battery known in the prior art is the lead gel storage battery, in which the sulfuric acid electrolyte is generally fixed in the form of gel formed on the basis of silicon dioxide. Hitherto, it is known from the prior art, for example US Pat. No. 4,317,872, to batch-produce electrolytic gels on the basis of dispersions of acid and gelling agents and to feed them into battery cells. However, the mass produc...
