Technology
After delivery to a lead-acid battery manufacturer, the separator roll is fed to a machine that forms "envelopes" by cutting the separator material and sealing its edges as shown in Figure 3. Next, either a positive or negative grid that is pasted with electrochemically active material is inserted into the envelope to form an electrode package.
