The Evolution of Mobile Phone Batteries: From Ni-Cd to Li-ion

The evolution of mobile phones has been nothing short of remarkable. The style, functionality, and capabilities of mobile phones have changed significantly over time, from the heavy and pricey gadgets of the 1980s to the elegant and sophisticated smartphones of today. One of the key components that have played a crucial role in this evolution is the battery. Without a reliable and efficient source of power, mobile phones would not have been able to become the ubiquitous devices that we know today. Extended battery life, quicker charging times, and more efficiency are the outcomes of notable breakthroughs in the evolution of mobile phone batteries over time. This study will examine the switch from Ni-Cd to Li-ion batteries used in mobile phones and how it affected the development of these devices.
