Advantages of 18650 battery.

Before entering the field of new energy vehicles, 18650 batteries were widely used in electronic products and were the earliest, most mature, and stable lithium-ion batteries. After years of experience accumulation, Japanese manufacturers have excellently applied the advanced technology accumulated by 18650 batteries in consumer products to the field of automotive batteries. Panasonic is one of the world's largest companies in battery technology and scale. Compared to other manufacturers, it has the least product defects and a larger scale, making it easy to select batteries with good consistency.

In contrast, other batteries such as stacked lithium-ion batteries are far from mature, and many products cannot even be standardized in size, dimensions, etc., and the production processes possessed by battery manufacturers cannot meet the conditions. Overall, the consistency of batteries cannot reach the level of 18650 batteries. If the consistency of the batteries does not meet the requirements, the management of battery packs formed by a large number of batteries connected in series or parallel will not be able to better utilize the performance of each battery. However, 18650 battery cells can effectively solve this problem.

18650 lithium batteries have high safety performance, do not explode, and do not burn; Non toxic, pollution-free, certified with RoHS trademark; And it has good high temperature resistance, with a discharge efficiency of 100% at 65 degrees Celsius.

18650 batteries are generally packaged in steel shells, which can minimize the occurrence of safety accidents and provide higher safety in extreme situations such as car collisions. In addition, the 18650 has a small size for each battery cell, which allows the energy of each cell to be controlled within a smaller range. Compared to using large-sized battery cells, even if a unit in the battery pack fails, the impact of the failure can be reduced.

The capacity of 18650 lithium batteries is generally between 1200mAh and 3600mAh, while the capacity of general batteries is only about 800mAh. If combined into an 18650 lithium battery pack, the 18650 lithium battery pack can exceed 5000mAh. Its capacity is 1.5 to 2 times that of nickel hydrogen batteries of the same weight, and it has a very low self discharge rate. The energy density of 18650 battery cells can currently reach a level of 250Wh/kg, meeting Tesla's requirements for high range.

The lifespan of 18650 lithium batteries is very long, with a normal cycle life of over 500 times, which is more than twice that of ordinary batteries. The 18650 product has a high level of technological maturity, with mature structural design, manufacturing technology, manufacturing equipment, and derived 18650 module technology, which reduces its operating and maintenance costs.
