Cell phone batteries use the same technology and follow the same principles used in traditional battery cells but face more challenges due to the constant and widespread use of cellular devices.
Chemical Types
Cell phone batteries are made from nickel-cadmium, nickel-metal hydride or the most advanced lithium-ion.
Quick Charging
A team of MIT scientists have invented a lithium-ion battery capable of being charged in 10 seconds. It does not require any radical changes to manufacturer's current processes, and widespread production is being explored.
Memory Effect
New cell phone batteries will try to eliminate the memory effect, which diminishes battery life and eventually leads to complete discharge. This is caused by overcharging or recharging a battery before the life is fully exhausted.
Long-term Life
Current cell phone battery technology allows it to be recharged 200 to 400 times before being permanently discharged. New technology is being worked on to extend battery life, possibly infinitely, as well as cut down on battery waste.
Green Batteries
Technological advances in cell phone batteries will continue to use even more environmentally friendly materials. Lithium-ion batteries were already a major upgrade from the heavy metals previously used in nickel-based batteries, but it is likely this trend will continue as volume grows.
