Battery Plates
Rechargeable nickel metal hydride (NiMH) batteries are constructed using nickel as the positive node. The nickel electrodes, or cathodes, are grids or screens of varying configurations that are readily produced by photo etching. NiMH batteries are rapidly replacing NiCad because they do not contain toxic cadmium and offer better life cycle performance.
Q: Do you have any standard screens? A: No. Everything is made to customer specifications.
Q: Do the holes have to be round? A: No. The holes can be virtually any shape and they don’t have to be the same shape. Any collection of shapes can be made. The caveat is that the minimum radius is equal to the material thickness and the 120% rule applies to the narrowest area of an opening.
Q: Can screens have solid borders? A: Yes.
Q: What are the limitations for etched screens? A: The minimum hole size needs to be, preferably, 120% of the metal thickness and the minimum ligature between holes is not less than the metal thickness and never less than .005 inches.
Q: What is the largest screen you can make? A: Our equipment can process screens up to 24” x 60”
Q: What are the thinnest and thickest materials you can process? A: .001 inches in most alloys and up to .080 inches in aluminum.
Q: How much do etched screens cost? A: For common alloys (stainless, copper, brass, aluminum) between .010 and .020 thick, you can expect costs between .20 and .30 per square inch, assuming 120% minimum hole size.
