Is the cell phone battery a lithium battery? After reading this article, you will understand
Many users often pay attention to the type of mobile phone battery when analyzing the hardware configuration of mobile phones, but because of lack of knowledge in this area, they are not sure what type of batteries are used in current mobile phones. This article combines the development history of mobile phones to talk about Types of cell phone batteries.
Most mobile phones use "lithium batteries" as power and energy storage tools
With the continuous breakthrough of technology, smartphones have basically replaced all old-fashioned mobile phones. Based on the high power consumption of smartphones, lithium batteries are very popular after their birth and are immediately applied to smartphones as "power supply and energy storage tools". "use.
Lithium battery is a kind of smart battery. The only difference from traditional old-fashioned mobile phone batteries is that it has a long service life, high storage capacity density, high rated voltage, high power tolerance, low discharge rate, light weight, high and low temperature environment adaptation.
Types of mobile phone batteries
Mobile phone batteries are roughly divided into two categories, one is lithium battery, which is the battery used in most smart phones; the other is nickel battery, which is used in some old mobile phones.
On this basis, batteries are also subdivided into some small categories, such as lithium batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-hydrogen batteries and so on. In addition to the difference in material, the performance is also very different. They all belong to a kind of "energy storage tools" for mobile phone power supply, while lithium batteries and lithium polymer batteries are the iterative products of nickel-cadmium batteries and nickel-metal hydride batteries.
The difference between the two batteries
In addition to the performance gap, the biggest gap between lithium batteries and nickel batteries is the "memory effect", because the charging part and the discharging part of nickel batteries are not completely consistent, which will lead to a temporary reduction in the battery capacity and reduce the battery life of the mobile phone. capacity, and this is also the reason for the rumors that "the first time you use a new mobile phone, you need to fully discharge the power".
But lithium-based batteries do not have this problem. In addition to having all the functions of nickel-based batteries, they have been greatly improved. Under the control of the smartphone charging IC system, they surpass nickel-based batteries in all aspects.
