Final answer:
The four basic types of secondary cells are nickel-cadmium (NiCd), lead acid, lithium ion, and nickel-metal hydride (NiMH). These rechargeable batteries each have distinct characteristics that make them suitable for various applications in electronics, automotive, and industrial settings.
Step-by-step explanation:
The four basic types of secondary (wet) cells are nickel-cadmium (NiCd), lead acid, lithium ion, and nickel-metal hydride (NiMH) batteries. Secondary cells are defined by their ability to be recharged, which means the chemical reactions that occur within the cell are reversible.
Each type of secondary battery has its unique advantages and applications based on factors such as energy density, cost, longevity, and memory effect.
For instance, nickel-cadmium batteries have been widely used in various electronic devices and tools due to their durability and high discharge rates. Lead acid batteries are commonly found in automotive and industrial settings because of their high current output and affordability.
Lithium ion batteries are popular in consumer electronics and electric vehicles for their high energy density and lightweight. Lastly, nickel-metal hydride batteries are considered an environmentally friendlier alternative to NiCd batteries and offer good energy density, making them suitable for hybrid vehicles and personal electronics.
