What are the types of cell phone batteries?
In recent years, light weight, energy, no self-discharge of lithium-ion battery turned out to be popular with the vast number of consumers, the current mobile phone battery development trend.
The second generation of nickel-metal hydride battery capacity than nickel-cadmium batteries more than 30% to 50%, mobile phone talk time and therefore extended by 30%. Its manufacturing materials have little environmental pollution (no cadmium metal), people used to call it environmentally friendly batteries. But nickel-metal hydride batteries also exist self-discharge, normal room temperature, nickel-metal hydride battery power loss rate of 1 to 3% per day, a fully charged nickel-metal hydride batteries placed a few weeks before use should be recharged.
Nickel-cadmium batteries are the first generation of mobile phone batteries, composed of two plates, one is made of nickel, the other is made of cadmium, the two metals in the battery reversible reaction occurs, so the battery can be recharged. But its capacity is low, there is a memory effect, the need for frequent discharge to maintain capacity, and the existence of environmental pollution of materials, the current battery has been basically eliminated.
Cell phone commonly used batteries are: nickel-cadmium batteries, nickel-metal hydride batteries and lithium-ion batteries.
