Super batteries with high charge density are also called:
Correct answer: B. Secondary batteries
- A. Primary batteries
- B. Secondary batteries
- C. Solar batteries
- D. Fuel batteries
Explanation
Secondary batteries, also known as rechargeable batteries, have high charge density and are designed to be reused multiple times. They can be charged, discharged, and recharged many times, making them a popular choice for applications where battery longevity is important. Examples of secondary batteries include lead-acid batteries, lithium-ion batteries, and nickel-cadmium batteries.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
