Definition

Noun: A storage-battery grid is a perforated or corrugated metal plate used in a storage battery. Its primary functions are to act as an electrical conductor and to provide structural support for the battery's active material.

Usage

This term is highly technical and specific to the field of electrochemistry and battery engineering. It refers to a core internal component of a lead-acid battery or similar rechargeable battery. * The storage-battery grid holds the paste-like active material (lead dioxide or sponge lead) that participates in the chemical reactions. * Its design (perforated or corrugated) maximizes surface area for the active material while allowing for electrolyte flow and structural integrity.

Examples

• The lead alloy used for the storage-battery grid must resist corrosion to ensure a long service life.
• During manufacturing, the active material is pressed into the storage-battery grid.
• Battery failure can occur if the storage-battery grid deteriorates or becomes distorted.

Advanced Usage

• Grid Design: The specific pattern (e.g., rectangular, radial) of the storage-battery grid is engineered to optimize current distribution and minimize electrical resistance within the cell.
• Grid Alloy: The metal composition of the storage-battery grid (often a lead-calcium or lead-antimony alloy) is critical for mechanical strength and to reduce gassing during charging.

Variants and Related Words

• Grid (Noun): In this specific context, "grid" is a shortened, informal form of "storage-battery grid." (e.g., "The positive and negative grids are made of different alloys.")
• Plate (Noun): Often used synonymously with "grid" in battery terminology, though "plate" can sometimes refer to the complete assembly of the grid plus its active material.
• Current Collector (Noun): A more general engineering term for a component, like a grid, whose function is to conduct electricity to and from an active material.

Synonyms

• Battery grid
• Plate grid
• Electrode grid

Related Phrases

• Positive grid: The storage-battery grid that supports the positive active material (lead dioxide).
• Negative grid: The storage-battery grid that supports the negative active material (sponge lead).
• Grid corrosion: A common failure mode where the storage-battery grid oxidizes and weakens.

Noun

1. a perforated or corrugated metal plate used in a storage battery as a conductor and support for the active material
