Abstract: A method with and associated apparatus for vibration-filling electrodes in a paste bath. A holding tool connected to a vertical rotary shaft carries the electrode and, arranged above it, a vibration reflection body. The electrode and vibration reflection body are immersed in the paste bath, filling of the electrode is carried out, and the holding tool, electrode and reflection body are withdrawn from the paste bath. Above the paste bath, the excess paste is spun off the electrode by rotating the vertical rotary shaft, the reflection body also being cleaned of the paste.

Abstract: A process and device provide for the virtually continuous vibration filling with active compound of empty fiber structure electrode plaques having a welded-on current discharge lug for electric accumulators. The empty fiber structure electrode plaques are inserted into a transport device having an adjustable cycle time which passes the plaques through a trough filled with active compound in which the active compound is vibrated. The fiber structure electrode plaques are then removed from the trough, excess active compound is stripped off, sides and the edges of plaque are freed from residues of excess active compound by various brushes. The filled fiber structure electrode plaque is then removed from the transport device, after prior drying, if required.

Abstract: A simple device for the vibration filling of porous fiber structure electrode plaques for voltaic cells includes a vibrating plate having a principal extension arranged substantially vertical within a filling chamber. An electrode plaque is arranged with a principal surface substantially parallel to the principal surface of the vibrating plate at a distance of about 2 to 50 mm from the vibrating plate (when swung in to the maximum extent). The distance of the vibrating plate from the base of the filling chamber is at least about 1 mm. It is possible to fill a series of electrode plaques with one charge of the filling chamber, the filling operation for the electrode plaque proceeding very rapidly and with considerably less noise then known devices, in which the entire filling vessel is vibrated.

Abstract: An automatically operating apparatus and method for producing cathodes for ry-cell batteries, especially lithium batteries. A strip-like carrier material to which cathode material is fed in a dosed manner is transported on an endless, continuously rotating conveyor belt system. After passing a pasting mechanism, which includes a roller, and after passing a possibly provided cleaning mechanism for exposing the contact locations for the current shunting, the cathode material subsequently passes into a pressing mechanism that includes two rotating belts. Following the pressing mechanism is a cutting device that, just like the cleaning mechanism, moves synchronously with the conveyor belt system during processing, and that cuts the carrier material in conformity with the cathode lengths. Subsequently, the current shuntings are attached.

Abstract: This invention relates to a method of producing a paste-type electrode for a lead storage battery which comprises packing into an active material support a paste prepared by kneading a lead oxide having a conversion ratio to red lead (Pb.sub.3 O.sub.4) of 90% or less or a mixture of this lead oxide powder with water and sulfuric acid as the principal components. Because this lead oxide contains red lead less than 90%, red lead formed on the surface of this oxide and lead oxide (PbO) formed in the particle core are directly bonded. This enhances the bonding power between the active materials. The paste-type electrode prepared by this method provides high adhesion of the paste to the active material support and high bonding power between the active materials. Therefore, both improvements in life and in efficiency of formation charge can be attained.

C. The paste is preferably set in vibration with a frequency of about 40 to 125 Hz and an amplitude of about 0.1 to 1.5 mm by a vibration transmitter fitted inside the tank containing the paste.

Abstract: A lead-oxide paste mix for use as an active material superimposed upon the plates of a lead-acid rechargeable battery. Battery grades of oxides of lead are mixed with a dilute solution of hydrogen peroxide, either alone or with additives and/or expanders. The resultant paste offers such advantages as reduced curing and drying times and/or the elimination of the need for curing and drying, lower dry active material weights and improved cohesion when compared to conventional pastes manufactured from leady oxides, sulfuric acid, and water.

Abstract: A paste hopper control system in which the weight and thickness of lead oxide paste applied to a stream of battery grid material from a hopper are independently controlled in response to in-line weight and thickness measurements obtained downstream of the paste hopper. Paste weight is independently controlled on the two sides of the stream by separately driving transversely spaced, independently rotatable hopper paddles in accordance with weight measurements obtained on the respective sides of the stream. Plate thickness is independently controlled on the two sides of the stream by adjusting the heights of the ends of a trowel roller in accordance with downstream thickness measurements and by adjusting the height of the hopper as a unit.

Hydraulic jacks are provided for raising and lowering the bath to and from an elevated position in which the graphite roller is immersed in the bath.
