Do you know the types and characteristics of cell phone batteries?

There are three types of cell phone batteries: nicad, nimh and lithium ion.

Nickel-cadmium

battery nickel-cadmium battery is the first generation of cell phone batteries. It consists of two plates, one made of nickel and the other made of cadmium. The two metals react reversibly in the battery, so the battery can be recharged.But it has low capacity, memory effect, need to discharge often to maintain capacity, and the manufacturing material has environmental pollution, the current battery has been basically out of use

NI-MH battery

Nickel-metal hydride batteries the second generation of nickel-metal hydride batteries have a capacity of 30 to 50 percent more than nickel-cadmium batteries, resulting in 30 percent longer call times on mobile phones

lithium ion battery

In recent years, the lithium ion battery with light weight, large energy and no self-discharge has emerged, which is welcomed by the majority of consumers.
