Rechargeable battery protection circuit board is to remove the batteries. It is a rechargeable battery power storage section, such as solar power storage. Quality batteries directly determines the quality of the rechargeable battery.

Difference polymer batteries with conventional lithium-ion battery that production process. Lithium is wound from the volume softer. Polymer is a superposition, hard body. The same volume of polymer and lithium batteries, larger capacity of the polymer, higher than about 30%. And safer, smaller explosion risk.

Structure

Lithium-ion rechargeable battery composed like this: batteries + protective circuit board. Rechargeable battery protection circuit board is to remove the batteries. He is part of an electric storage battery. Quality batteries directly determines the quality of the rechargeable battery.

Classification

Batteries into aluminum batteries, soft pack batteries (also known as "polymer core") cylindrical batteries of three. Mobile phone battery is generally used aluminum batteries, Bluetooth and other digital products to use more soft package batteries, laptop battery uses a combination of series and parallel cylindrical cells.

Characteristic

Lithium batteries and polymer batteries comparative advantages and disadvantages

The advantages of lifePo4 batteries is that the discharge of power, at the same voltage, current limit is greater than the polymer batteries, which means that the output performance of lithium batteries good power, can be used in some devices require high instantaneous current above can guarantee stability of the system.

The disadvantage of lithium batteries in its smaller capacity, generally about 800MAH, lithium batteries and instability under short circuit and external harsh environments are explosive, and when lithium batteries short-circuiting its explosive metal shell surface in highly lethal.

Advantages polymer batteries is strong endurance, high capacity, large volume of the same polymer batteries lithium batteries than 20% of capacity, strong endurance under steady state current output, and its surface is a flexible material as the pack, so it also can be used in portable solar power generator. If you have a short circuit resulting in the battery does not explode bulging, will split, so safe.

Disadvantage is that the peak current is not large lithium batteries, in some cases, require large current moment some stretched on the.
