Correct Answer

Explanation

The electrolyte in a Nickel-Iron (NiFe) accumulator, also known as an Edison battery, is typically a potassium hydroxide (KOH) solution. This electrolyte serves as a medium for the transfer of ions between the nickel and iron electrodes during the charge and discharge cycles of the battery. NiFe batteries are known for their durability and long cycle life, making them suitable for certain applications, such as backup power systems and renewable energy storage.
