2. Lithium-polymer (Li-Po)
3. Nickel-cadmium (NiCd)
4. Nickel-metal hydride (NiMH)

Lithium-ion (Li-ion):
Lithium-ion (Li-ion) batteries are widely used in laptops. They have a high energy density, which means they can store a significant amount of energy in a small space. Li-ion batteries charge quickly, typically within two to four hours. According to a 2020 study by NREL, Li-ion batteries have a cycle life of around 500 to 1000 charge-discharge cycles. Common laptop manufacturers like Dell and Lenovo predominantly use this technology in their devices.

Lithium-polymer (Li-Po):
Lithium-polymer (Li-Po) batteries are another common type found in laptops. They offer similar performance to Li-ion batteries but have a flexible structure. This allows for various shapes and sizes that can fit into thin laptops. Li-Po batteries provide a lighter option, which is appealing for portable devices. Research from the University of Cambridge shows that Li-Po batteries can achieve higher specific capacities, enhancing battery longevity and performance.

Nickel-cadmium (NiCd):
Nickel-cadmium (NiCd) batteries are less common in modern laptops but were popular in earlier models. They have a lower energy density compared to lithium-based batteries and suffer from memory effect, which reduces their capacity over time if not fully discharged before recharging. The U.S. Environmental Protection Agency indicates that NiCd batteries are also less environmentally friendly due to cadmium’s toxicity. Despite these drawbacks, they can perform well in extreme temperatures.

Nickel-metal hydride (NiMH):
Nickel-metal hydride (NiMH) batteries are another alternative, featuring higher energy capacity than NiCd batteries but still lacking behind lithium technologies. These batteries do not have a significant memory effect, making them a better option for deep discharge scenarios. A study in the Journal of Power Sources (2018) states that while NiMH batteries are somewhat less efficient than Li-ion and Li-Po, they can be recycled more easily. They are often found in older laptops or as backup batteries in some devices.
