Glossary of Terms

The positive plate of a storage battery consists of the grid and the active material from which current flows to the external circuit when the battery is discharging. Positive Terminal The terminal from which current flows (as ordinarily conceived) through the external circuit to the negative terminal when the cell discharges.

Comparison Between Flat & Tubular Positive Plates in Lead-Acid Batteries

Due to increased positive plate surface area, tubular batteries have 20% more electrical capacity than flat plate batteries of comparable size and weight. With less positive plate shedding, tubular batteries also provide up to a 30% longer service life than flat plate batteries.

Lead-Acid Batteries

All lead-acid batteries consist of two flat plates—a positive plate covered with lead dioxide and a negative made of sponge lead—that are immersed in a pool of electrolyte (a combination of sulfuric acid (35%) and water solution (65%). Electrons are produced from the chemical reaction producing voltage. When there is a circuit between the

Battery Failure Mode: Positive Plate Active Material Softening

The discharge and charge process cause first the expansion, then the contraction of the positive (+) active material. Expansion occurs both in the plane (height and width) of the plate as the grid is pushed/stretched by corrosion processes over time and in the thickness of the plate as the active material is forced to expand to accommodate the lead sulphate ("PbSO 4 ") with each

How does a lead battery plate work?

The electrolyte is then free to enter all the tiny holes in the sponge, thereby increasing the effective capacity of the battery. The negative and positive lead battery plates conduct the energy during charging and discharging. This pasted plate design is the generally accepted benchmark for lead battery plates.

What is the positive active material of a lead–acid battery?

What is a positive electrode in a lead-acid battery?

In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead. Whereas this so-called ‘Planté plate’ is still in demand today for certain battery types, flat and tubular geometries have become the two major designs of positive electrode.

What makes a positive plate?

Assembling the spines, gauntlets, lead oxide, and bottom bar together makes a positive plate. Volume changes during discharge and charge are mostly compensated by a high mass porosity, and gas bubbles help to distribute remaining free particles in the cell. Pressing the PbO corrosion layer onto the grid surface also helps to protect the lead grid
