Advantages of 18650 lithium battery
The shadow of 18650 lithium batteries can be seen in many fields, because this type of battery has obvious advantages compared to other batteries, and its safety is relatively good. It has even been used in large-scale equipment. This article will introduce the knowledge of 18650 batteries to you.
The difference between lithium battery soft pack and hard pack mainly refers to the material of the outer shell of the lithium battery pack. If there is packaging on the outside, it is difficult to distinguish. It is important to see the battery body. Aluminum shell batteries weigh more than batteries of the same volume, but it is really difficult to distinguish between aluminum shell and soft pack. However, soft pack batteries are slightly softer than aluminum shell batteries and are extremely prone to deformation when broken by hand.
High security
18650 lithium batteries have high safety performance, do not explode, and do not burn; Non toxic, substance contaminated, certified with RoHS trademark; All kinds of safety performance are achieved in one go, with more than 500 cycles; Good high temperature resistance, with a discharge efficiency of 100% at 65 degrees Celsius. To prevent battery short circuits, the positive and negative poles of 18650 lithium batteries are separated. So the possibility of it experiencing a short circuit has been reduced to the extreme. Protective plates can be installed to prevent overcharging and overdischarging of the battery, which can also extend its lifespan.
Long service life
The lifespan of 18650 lithium batteries is very long, with over 500 cycles during normal use, which is more than twice that of regular batteries.
Large capacity
The capacity of 18650 lithium batteries is generally between 1200mAh and 3600maH, while the capacity of a group of batteries is only about 800. If 18650 lithium batteries are combined to form an 18650 lithium battery pack, the 18650 lithium battery pack can easily exceed 500maH
Low internal resistance
The internal resistance of polymer battery cells is smaller than that of general liquid battery cells, and the internal resistance of domestic polymer battery cells can even reach below 35m Ω, greatly reducing the self consumption of batteries and extending the standby time of mobile phones, which can fully reach the level of international standards. This type of polymeric physical lithium battery that supports high discharge current is an ideal choice for remote control models and has become the most promising product to replace nickel hydrogen batteries.
