How to choose 18650 lithium battery?

Lithium is the lightest non-gaseous metal substance in nature, and its connotative potential is lower than any other metal. Therefore, compared with other types of batteries, the lithium battery capacity (capacity per unit component) and bulk density (volume per unit volume) processed by the lithium battery spot welding machine are the highest and have unparalleled advantages. Compared with polyethylene lithium batteries, LiMnO2 batteries have advantages in terms of structural strength, bulk density, safety and output capabilities, but their service life is only half of the former. The internal resistance of this battery is lower than other batteries, which is very suitable for devices that require high-current continuous (or short-term) power supplies. The activity data of lithium iodide battery is completely solid state, so it is the best. An isolation layer is planned inside the battery. When the outer shell is damaged by external force, the isolation layer can play a self-healing purpose. The biggest drawback of lithium iodide batteries is that they have large internal resistance and are not suitable for small load equipment. The most widely used in the military/aerospace field is LiSO2 batteries. However, the battery pack density of this type of lithium battery assembled production equipment is lower than that of LiMnO2 batteries and polyethylene batteries, and its service life and volume density are only half of LiSOCl2 batteries. Among all 18650 lithium batteries, LiSOCl2 battery has the highest energy density, and its service life is among the best, reaching 15 to 20 years. This type of battery is particularly suitable for devices with small continuous supply current and relatively short supply current. Due to the long battery life and low self-discharge rate, the battery's environmental resistance is also excellent.
