Abstract
The present invention is directed to a method of manufacturing battery grids. In particular, a method of simultaneously casting multiple battery grid strips on a continuous casting machine is provided. The mold includes a bipartite grid cavity having a pair of adjacent grid cavity segments which communicate with each other through a common groove such that the resultant dual grid strip formed thereon includes a corresponding pair of grid strip segments that are interconnected by a series of flexible or frangible nodes. A dual grid strip can be folded along the flexible or frangible nodes to form a layered grid strip. The layered grid strip is then pasted with an active material and cut into individual battery plates.
Claims16
A battery grid comprising:
- a first reticulum for retaining chemically active battery paste material, said first reticulum formed from an electrically conductive material comprising lead or a lead alloy;
- a second reticulum for retaining chemically active battery paste material, said second reticulum formed from an electrically conductive material comprising lead or a lead alloy;
- an open mesh reinforcing scrim layer mounted between and bonded to said first and second reticulum;
- and
- means for conductively connecting said first and second reticulum.
A battery grid comprising:
- a first reticulum for retaining chemically active battery paste material, said first reticulum formed from an electrically conductive material;
- and
- a second reticulum for retaining chemically active battery paste material, said second reticulum formed from an electrically conductive material;
- and
- means for integrally connecting said first and second reticulum.
A battery grid, comprising:
- first and second integrally connected reticulums for retaining chemically active battery paste material, said first and second reticulum being formed from wires comprising lead or a lead alloy wherein a first set of wires is substantially traverse to a second set of wires, said first set of wires including backribs and wherein the wires of said first reticulum are not aligned with the wires of said second reticulum.
