Abstract:
The subject matter of the invention is a battery forming unit, being used at the final stage of a production line, where the batteries are electrochemically formed. It is characterized in that the tank (1) on/in its side walls (4) has water ducts (5) containing water level regulators (6), with outlets over the cooler (7), installed in the area under the tank (1) over the liquid reservoir (8); moreover the tank (1) has air ducts (10) located on/in its side walls (4), with inlets over the area of the cooler (7) and the outlet in the area of the suction collector (11).
Abstract:
The invention relates to a system in which bridges (16, 18) with flanges (17, 19) for intercell connectors (24), said bridges connecting positive lugs (12), on the one hand, and negative lugs (14), on the other, are, in a casting station (270), cast onto the lugs (12, 14) of positive and negative battery plates, which are assembled to form packs (10), after subjecting the lugs (12, 14) to a pretreatment by brushing and with flux. The packs (10), which are comprised of battery plates and which are provided with bridges (16, 18) in the aforementioned manner, are placed inside compartments (22) for cells in battery cases (20) while being arranged in groups each consisting of three packs. Cassettes (30) are used for moving the packs (10) of battery plates, and the packs (10) are held in these cassettes while being squeezed between fixed and moving partitions (305, 307). The packs (10) are placed inside these cassettes (30) in such a manner that solely lugs (12) of positive plates are placed on one longitudinal side, and solely lugs (14) of negative plates are placed on the other longitudinal side.
Abstract:
An interleave machine for stacking a plurality of generally flat objects and a method for stacking a plurality of generally flat objects and components, steps and/or assemblies of an interleave machine, including but not limited to a Bernoulli pick up and place device and the steps of using the size and shape of a plate to determine the fold (or crease) point of a surrounding separator.
Abstract:
The subject matter of the invention is a battery forming unit, working as a final element of a production line, where the batteries are electrochemically formed. The unit consisting of a base for placing assembled batteries and electric forming equipment, is characterized in that the base is a belt conveyor (3) located in a tank (1) with at least one declining wall (2), and a inflow (6) and outflow (8) system.
Abstract:
A manufacturing process and an apparatus to carry out the process are disclosed which eliminate or at least significantly reduce the occurrence of damaging localized short circuits in the production of electrochemical generators. The process and apparatus include cauterization by oxidation of the anode edges of multiple electrochemical cell laminates thereby rendering the anode edges electrically insulated from adjacent cathodes and/or current collectors.
Abstract:
A discontinuous cathode sheet structure is incorporated within thin-film electrochemical halfcells and full cells. A thin-film electrochemical cell structure includes a cathode sheet layer comprising a series of discontinuous cathode sheets. In a monoface configuration, each of the cathode sheets includes one cathode layer in contact with a current collector layer. In a biface configuration, each of the cathode sheets includes a pair of cathode layers each contacting a current collector layer. A gap is defined between adjacent ones of the cathode sheets. A solid electrolyte layer contacts a surface of one or both cathode layers, depending on the configuration, and extends across the gaps defined between the adjacent cathode sheets. The cathode sheets may be arranged in a number of rows to define a matrix of the cathode sheets.

Abstract:
A production method of a lithium secondary battery comprising the step of spraying a melt (61) of a solid electrolyte over at least one plate selected from an anode plate (20) and a cathode plate (30) to deposit the melt (61) on at least one plate, and the step of pressing the anode and cathode plates (20), (30) with the melt (61) held therebetween to thereby form a laminate including the anode plate (20), an electrolyte layer (62) consisting of a solid electrolyte and the cathode plate (30), whereby it is possible to produce a thin, good−characteristic lithium secondary battery with an efficient productivity.
