1800mah 18650 battery.What is the difference between polymer lithium battery and 18650 lithium battery?

1. Different types of batteries

18650 lithium batteries can be divided into 18650 lithium-ion batteries, 18650 lithium iron phosphate batteries, and 18650 nickel-metal hydride rechargeable batteries; AA batteries include nickel-metal hydride rechargeable batteries, nickel-cadmium rechargeable batteries, and alkaline zinc-manganese batteries (referred to as "alkaline batteries"). "), ordinary acidic zinc-manganese batteries (called ordinary rechargeable batteries). In addition, polymer lithium batteries refer to lithium-ion batteries that use aluminum-plastic packaging film as outer packaging, that is, soft-pack batteries. This kind of film bag is composed of three layers: pp layer, al layer and polyester layer. Because pp and polyester are polymers, this lithium ion core is called a polymer lithium battery.


2. Different manufacturing processes

This article introduces the production and processing technology of lithium batteries. This technology can change the specifications and appearance design of battery production. It has the characteristics of low cost and good effect. It can make the rechargeable battery suitable for the appearance design according to the specific application regulations of the product and more suitable for user use. The production and processing technology of 18650 lithium-ion battery is a backline machine, which has fixed specifications and appearance design.

3. The dimensions of lithium batteries and 18650 are different

The most distinctive aspect of the lithium-ion battery in the lithium-ion layer is the difference in appearance design. The polymer lithium-ion is square and has a soft-packed battery shell; the 1865 lithium-ion is cylindrical, the shell is aluminum, and the battery is hard-packed; in addition , 18650 lithium ion has specifications, fixed height, and can be made into large capacity at 3200ma or below; polymer lithium ion batteries can be made into rechargeable batteries of various specifications and appearance designs, such as rectangular triangle, elevator, etc., natural ball shell batteries Can be more powerful.


4. Rechargeable batteries have different working voltages and capacities.

The working standard voltage is different and the volume is different. The normal 18650 rechargeable battery capacity is guaranteed to be about 2200ma, so the calculated energy is about 500wh/l.

Application fields of 18650

18650 lithium is used in consumer digital technology products such as pneumatic components, underwater vacuum cleaners, and solar street lights. 18650 rechargeable 18650 lithium-ion series and parallel assembly production and processing, 18650 rechargeable batteries can fully bear higher standards of current operating voltage.
