HOME / Drying of lead-acid battery green plates - RADIO-ENERGY
Lead-acid batteries, at their core, are rechargeable devices that utilize a chemical reaction between lead plates and sulfuric acid to generate electrical energy. These batteries are known for their reliability, cost-effectiveness, and ability to deliver high surge currents, making them ideal for a wide array of applications.

Dry charging of formed negative plates L. Prout Aydon Road, Corbridge, Northumberland NE45 5EN (UK) (Received August 14, 1992; accepted February 18, 1993) Abstract The objective in the dry charging of formed negative plates in lead/acid batteries is to preserve the highly active sponge lead material from attack by atmospheric oxygen until the
The invention discloses a rapid high-temperature curing drying process of a lead-acid storage battery unformed electrode plate. The process comprises the following steps of curing the unformed electrode plate which is coated with lead plaste in a curing chamber with the humidity of 95 to 99 percent and the temperature of 47 to 50 DEG C for 3 to 5h; increasing the indoor
For drying and curing battery plates. Curing is one of the most critical steps in lead-acid battery plate production, and can be decisive for the quality of the plates and the battery''s capacity and life cycle.The right choice of curing chamber will affect the quality of the active mass and determine the microstructure of the lead crystals, which play a central role in
The invention discloses a drying process of a lead-acid battery plate. A raw plate coated with lead paste is cured; the cured wet raw plate enters a drying stage; in the drying stage, the temperature of the inner environment of a curing chamber is adjusted to 80 to 85 DEG C, the relative humidity is adjusted to be 8 to 12%, and the lasting time is 12 to 15h; after the drying stage is completed

G. TIEGEL (Tiegel Manufacturing Co., U.S.A.): Have you analysed plates dried in a so-called flash dryer, drying time about 12 seconds under severe radiation from a 1500°F source, drying only the surface of the plate and retaining practically all the moisture within the plates. Curing temperature not to exceed 160°F.
Wetting the plates during curing also provided better process control. Burlap or canvas was used for this purpose Many areas similar to this still exist m plants today and yield serviceable plates.
