The difference between lithium ion battery and 18650 battery

by:dcfpower     2020-10-17

so far has the maximum number of commercial applications on the market the battery is lithium battery and lithium battery this two kinds big, 18650 battery don't do friends, not many professional with high degrees of battery manufacturer all don't know what the two batteries. Let us 18650 lithium polymer battery manufacturer of professional engineers to you talk about lithium battery pack and lithium battery 18650 the difference between what?

1。 There are different kinds of battery

18650 lithium batteries can be divided into 18650 lithium ion battery, 18650 of phosphorus acid lithium iron batteries, I 18650 nickel metal hydride rechargeable batteries; And v battery is nickel metal hydride rechargeable batteries, nickel cadmium rechargeable batteries, alkaline zinc manganese battery ( Hereinafter referred to as & other; Alkaline batteries & throughout; ) , common acidic zinc manganese battery ( Hereinafter referred to as & other; Common battery & throughout; ) And so on. In addition some people: polymer battery is refers to the use of aluminum-plastic packaging film packaging of lithium ion battery, battery is an alias of the soft bag. This kind of packaging film consists of three layers, respectively is PP, Al layer and nylon layer, is due to PP and nylon polymer, therefore this kind of batteries is called a polymer battery.

2。 Manufacturing process is not the same as

lithium battery pack production manufacturing process is fold type, this process can deploy productively low cost change size and shape of battery manufacturing, according to the actual use of products demands to produce appropriate shape of the battery, make full use of product space, make the product more reach the use requirement of the buyer. 18650 lithium battery pack production manufacturing process is winding type, size and shape are fixed.

3。 Lithium batteries and 18650 appearance size shape is not the same as

18650 lithium battery pack and lithium battery is the most intuitive in batteries is different in shape, polymer lithium battery are square, shell is aluminum composite membrane, is soft package of batteries; 18650 lithium battery is a cylindrical shell is a steel shell, is a rigid package; At the same time 18650 lithium battery size is only one size, its diameter and high is fixed, maximum capacity of 3200 ma or you can do the following; The polymer lithium battery is different, it can make all kinds of size size and shape of the battery, such as a right triangle, ladder type, semi-circular, of course besides spherical, meanwhile can better control on the battery capacity.

4。 The working voltage of the battery capacity is different

is different working voltage, capacity is different. Generally the 18650 before, during and after the 2200 mah battery capacity do so calculate down energy density of about 500 wh/L.

18650 lithium-ion batteries use field

& reg; 18650 lithium-ion batteries used in electric tool accessories, underwater vacuum cleaners, solar lamp and other consumer digital products. Can meet the customized needs of customers, according to the parallel of 18650 batteries assembled production and become, 18650 battery completely can be competent the job of a larger voltage larger electric current.
