Abstract
An accumulator having a plurality of electrode plates which are adjacently arranged and form at least one electrode plate stack in the form of a block, wherein each electrode plate comprises a frame having a grid arranged therein and wherein at least the grid is filled with an active mass, and wherein each electrode plate comprises at least one connecting lug protruding beyond the frame, wherein the connecting lugs of same-polarity electrode plates are arranged adjacent to one another in a row, wherein the connecting lugs adjacently arranged in a row are materially bonded together electrically and mechanically into a connecting lug block by at least one weld or solder point arranged between the connecting lugs. Further described is a method for manufacturing an accumulator.
Claims17
An electrode plate comprising:
- a frame having a frame thickness;
- a grid arranged within the frame, the grid having a grid thickness;
- a connecting lug protruding beyond the frame, the connecting lug having a lug thickness provided in an area forming a connecting lug block, the lug thickness being greater than the frame thickness and the frame thickness being greater than the grid thickness;
- and
- a first portion of the electrode plate between the lug thickness and the frame thickness and a second portion of the electrode plate between the frame thickness and the grid thickness, the first portion having a first varying thickness from the lug thickness to the frame thickness and the second portion having a second varying thickness from the frame thickness to the grid thickness.
An accumulator comprising:
- a cell;
- an active mass;
- and
- a plurality of electrode plates arranged adjacently within the cell to form an electrode plate stack, each electrode plate of the plurality of electrode plates comprising:
- a frame having a frame thickness;
- a grid arranged within the frame, the grid having a grid thickness and the grid being filled with a portion of the active mass;
- a connecting lug protruding beyond the frame, the connecting lug having a lug thickness provided in an area forming a connecting lug block, the lug thickness being greater than the frame thickness and the frame thickness being greater than the grid thickness;
- and
- a first portion of the electrode plate between the lug thickness and the frame thickness and a second portion of the electrode plate between the frame thickness and the grid thickness, the first portion having a first transitioning thickness from the lug thickness to the frame thickness and the second portion having a second transitioning thickness from the frame thickness to the grid thickness,
- wherein the connecting lug block of the plurality of electrode plates further includes an electrical and mechanical bond coupling each of the connecting lugs of same-polarity electrode plates.
