lead-acid battery
Học thuậtThân thiện
Definition
Noun: A lead-acid battery is a type of rechargeable battery that uses lead and lead dioxide as electrodes and a diluted sulfuric acid solution as the electrolyte. It is a common technology where each individual cell produces approximately 2 volts of electrical potential.
Usage
This term is used to describe a specific, widely-used technology for electrical energy storage. It is most commonly applied in contexts involving vehicles, backup power systems, and industrial applications. - It functions as a countable noun (e.g., a lead-acid battery, several lead-acid batteries).
Examples
- Noun:
- The car's starter motor is powered by a 12-volt lead-acid battery.
- For off-grid solar systems, deep-cycle lead-acid batteries are often used for energy storage.
- Recycling old lead-acid batteries is important for environmental safety.
Advanced Usage
- Technical Context: In engineering and chemistry, the term precisely denotes the electrochemical system based on the reaction between lead, lead dioxide, and sulfuric acid.
- The discharge reaction in a lead-acid battery converts lead and lead dioxide into lead sulfate.
Variants and Related Words
- Lead-acid accumulator: A less common synonym, using "accumulator," another term for a rechargeable battery.
- SLI battery (Starting, Lighting, Ignition): A common type of lead-acid battery designed primarily for automotive starting.
- Deep-cycle battery: A type of lead-acid battery designed for prolonged, steady discharge rather than short, high-current bursts.
- VRLA battery (Valve-Regulated Lead-Acid): A sealed, maintenance-free version of the lead-acid battery.
Synonyms
