How to choose a high-quality 18650 lithium battery?

How to choose 18650 lithium battery? Choose the appropriate battery according to the product usage. Nowadays, planners can easily think of lithium batteries when designing batteries for new products, but they lack the understanding of how to choose suitable batteries. Lithium is the lightest non-gaseous metal in nature, and its intrinsic potential is lower than that of any other metal. Therefore, compared with other types of batteries, the lithium battery spot welder has the highest capacity (capacity per unit weight) and bulk density (volume per unit volume) of the lithium battery, which has incomparable advantages. Compared with polyethylene lithium batteries, LiMnO2 batteries have advantages in terms of structural strength, bulk density, safety and output capacity, but their service life is only half of the former. The internal resistance of the battery is lower than that of other batteries, which makes it an ideal choice for devices that require high-current connection (or short-term) power supplies. The activity data of the lithium iodide battery is completely solid, so it is the best. The internal design of the battery has an isolation layer, when the outer shell is damaged by external force, it can repair itself. The biggest disadvantage of lithium iodide batteries is that they have large internal resistance and are not suitable for small load equipment. The most widely used battery in the military/aerospace field is LiSO2 battery. However, the battery stack density of lithium battery packaging and production equipment is lower than that of LiMnO2 and polyethylene batteries, and only half of the life and volume density of LiSOCl2 batteries. Among all 18650 lithium batteries, LiSOCl2 has the highest energy density, with a longest life span of 15 to 20 years. This type of battery is particularly suitable for devices with a small and relatively short power supply current. Due to the long life of the battery and the low self-discharge rate, the environmental resistance of the battery is also very good.
