Explanation
Correct answer: B) Lithium-ion (Li-ion)
Lithium-ion (Li-ion) and Lithium-ion Polymer (LiPo) are the two most common battery types used in modern portable devices such as smartphones, tablets, and laptops. Both battery types are known for their high energy density, light weight, and rechargeability, making them ideal for portable electronics.
Here's why the other options are not as common in modern portable devices:
- Nickel-Iron (Ni-Fe): This is an older battery technology, not commonly used in modern portable devices.
- Nickel-Metal Hydride (Ni-MH): While Ni-MH batteries were once used in devices like early digital cameras, they have largely been replaced by Li-ion and LiPo batteries in modern portable electronics.
- Nickel-Cadmium (Ni-Cd): These batteries have largely been phased out due to their lower energy density and environmental concerns related to cadmium toxicity.
