Lithium Battery introduction
The rechargeable battery removal protection board is the battery. He is the power storage part of the rechargeable Maintenance Free Battery. The quality of the battery directly determines the quality of the rechargeable battery.
The difference between a and a conventional lithium ion battery lies in the production process. The Lithium Battery is entangled and has a soft volume. The polymer is superimposed and has a hard body shape. For the same volume of polymer and Lithium Batteries, the polymer has a larger capacity, about 30% higher. And it is safer and the risk of explosion is small.
Structure
The composition of the lithium ion secondary rechargeable battery is such that the cell + protection circuit board. The rechargeable battery removal protection board is the battery. He is the power storage part of the battery. The quality of the battery directly determines the quality of the rechargeable battery.
The mobile phone board removes the outer casing, and then removes the protective circuit board in the electric board to leave the lithium battery.
classification
The battery core is divided into aluminum shell battery core, soft battery core (also known as "polymer battery core"), and cylindrical battery core. Generally, the mobile phone battery adopts an aluminum-clad battery core, and digital products such as Bluetooth adopt a soft-package battery core, and the battery of the notebook computer adopts a series-parallel combination of cylindrical batteries.

Advantages and disadvantages of lithium batteries and polymer batteries
The advantage of lithium battery is that the power of discharge is large. At the same voltage, the limit current is larger than that of polymer battery. That is to say, the output performance of lithium battery is good and the power is large, which can be used on some devices that require instantaneous high current. System stability.
The disadvantage of the lithium battery is that its capacity is small, generally around 800MAH, and the lithium battery is unstable in the short circuit and the external harsh environment, and the metal shell on the surface is extremely destructive when the lithium battery is short-circuited.
The advantage of polymer battery core is that it has strong endurance and large capacity. The same volume of polymer battery core is 20% larger than the capacity of lithium battery core. It has strong endurance ability under steady current output state, and its surface is flexible material as outer box. If a short circuit is encountered, the battery will not explode after it swells, it will only crack, so it is safe.
The disadvantage is that the peak current is not as large as the lithium battery, and it is somewhat stretched in some cases where instantaneous high current is required.
