Final answer:

Since 1996, cell phone batteries have evolved from Nickel-Cadmium (NiCd) to Nickel-Metal Hydride (NiMH), and then to Lithium-ion (Li-ion) and Lithium-polymer (Li-poly) batteries. The newer batteries offer higher capacity, longer lifespan, and no memory effect, allowing for longer battery life and smaller cell phone designs.

Step-by-step explanation:

Since 1996, there have been significant changes in cell phone batteries. The main types of cell phone batteries include:

  • Nickel-Cadmium (NiCd) batteries: These were commonly used in early cell phones but have declined in popularity due to their limited capacity, memory effect, and environmental concerns.
  • Nickel-Metal Hydride (NiMH) batteries: These replaced NiCd batteries and offered higher capacity and no memory effect. However, they were still not as efficient as newer battery technologies.
  • Lithium-ion (Li-ion) batteries: These are currently the most common type of cell phone batteries. They have higher energy density, longer lifespan, and no memory effect. Li-ion batteries have allowed for the development of thinner and lighter cell phones.
  • Lithium-polymer (Li-poly) batteries: These are a variation of Li-ion batteries that use a gel-like electrolyte. They offer even higher energy density and can be shaped into various forms, making them suitable for slim and curved phones.

In summary, cell phone batteries have evolved from NiCd to NiMH, and then to Li-ion and Li-poly batteries. These newer batteries have allowed for longer battery life, smaller form factors, and improved overall performance.
