nickel-iron battery
Học thuậtThân thiện
Definition
- Noun:
- A nickel-iron battery is a type of rechargeable electrical storage device. Its key components are a positive electrode (cathode) made of nickel oxide and a negative electrode (anode) made of iron, with an alkaline electrolyte solution of potassium hydroxide. Each individual cell in this battery type produces a nominal voltage of approximately 1.2 volts.
Usage
- The term nickel-iron battery is used to specifically identify this electrochemical storage technology, often in technical, historical, or comparative contexts related to energy storage.
- It functions as a compound noun. The hyphen links "nickel" and "iron" to show they jointly modify "battery," describing its electrode materials.
Examples
- Noun:
- The early electric vehicles sometimes used a robust nickel-iron battery.
- Compared to lead-acid batteries, a nickel-iron battery has a very long cycle life.
- The workshop manual described the procedure for maintaining the nickel-iron battery.
Advanced Usage
- Technical Specification: The defining characteristic is the use of a nickel oxide cathode and an iron anode with an alkaline electrolyte, making it distinct from other battery chemistries like lead-acid or lithium-ion.
- Historical Context: This battery type is known for its exceptional durability and long service life, often cited in discussions about vintage technology or applications requiring very robust batteries.
Variants and Related Words
- NiFe battery: A common abbreviated form using the chemical symbols for Nickel (Ni) and Iron (Fe).
- Edison battery: A historical name, as this technology was pioneered by Thomas Edison.
Synonyms
- Storage battery (general category): A rechargeable battery.
- Secondary cell (general category): Another term for a rechargeable electrochemical cell.
Related Terms (Not Phrasal Verbs)
- Alkaline battery: A broader category of batteries using an alkaline electrolyte, which includes the nickel-iron type.
- Nickel-cadmium (NiCd) battery: A related alkaline battery technology using a different negative electrode material.
- Cycle life: A key performance metric often associated with the long-lasting nature of nickel-iron batteries.
- Potassium hydroxide: The specific electrolyte solution used in this battery.
Noun
- a storage battery having a nickel oxide cathode and an iron anode with an electrolyte of potassium hydroxide; each cell gives about 1.2 volts
