nickel-iron accumulator
Học thuậtThân thiện
Definition
- Noun:
- A nickel-iron accumulator is a type of rechargeable battery (storage battery) that uses nickel oxide hydroxide for the positive electrode (cathode) and iron for the negative electrode (anode), with an alkaline electrolyte of potassium hydroxide. Each individual cell in this battery produces a nominal voltage of about 1.2 volts.
Usage
- The nickel-iron accumulator is known for its exceptional durability and long service life.
- Due to its robust construction, the nickel-iron accumulator was historically used in industrial and railway applications.
- Charging a nickel-iron accumulator requires a specific voltage regimen.
Advanced Usage
- The term is often used in historical or technical contexts describing early electric vehicles or stationary power backup systems.
- It is sometimes referenced for its environmental advantage of using non-toxic materials (iron and nickel) compared to lead-acid batteries.
