Why are
18650 lithium batteries popular?
Lithium ion batteries have many advantages, but there are also shortcomings. Lithium ion batteries are generally packaged with aluminum-plastic film, which is thin in thickness and has poor strength. In situations such as collisions, the aluminum-plastic film is prone to damage, causing safety accidents. 18650 lithium batteries are generally made of steel shells, which have good safety. With the continuous improvement of 18650 lithium battery processing level, safety is also constantly improving.
In terms of energy density, it is necessary to distinguish between the energy density of individual batteries and batteries. From the perspective of the energy density of a single battery, the 18650 battery has a higher energy density than other lithium-ion batteries, but the management system of the 18650 battery is much more complex, and the increased weight will result in the energy density of the battery pack being slightly lower than that of individual cells.
18650
lithium-ion batteries have the characteristics of large capacity, long lifespan, high safety, and are highly favored by consumers due to their small size, light weight, and convenient use. With the deepening of research on 18650 battery technology, it has reached a very high level of consistency and safety. Like early lead-acid batteries, the 18650 is also a relatively mature and stable battery in the current lithium battery family.
