18650 battery:

18650 batteries originally referred to nickel-metal hydride batteries and lithium-ion batteries. As nickel-metal hydride batteries are now less used, they now refer to lithium-ion batteries. 18650 is the originator of lithium-ion batteries-a standard lithium-ion battery model set by SONY in Japan in order to save costs, where 18 represents a diameter of 18mm, 65 represents a length of 65mm, and 0 represents a cylindrical battery. Common 18650 batteries include ternary lithium batteries and lithium iron phosphate batteries.


——Highly mature and consistent process:

Before entering the field of new energy vehicles, 18650 batteries have been widely used in electronic products. They are the earliest, most mature and most stable lithium-ion batteries. After years of relevant experience, Japanese manufacturers have accumulated 18650 batteries in consumer products. The advanced technology of the company is extremely well applied in the field of vehicle batteries. Panasonic is one of the world's largest battery technology and scale companies. Compared with other manufacturers, it has the fewest product defects and larger scale, and it is also easy to choose a battery with good consistency.

In contrast, other batteries, such as laminated lithium-ion batteries, are far from mature enough. Many products cannot even be unified in size and size, and the production technology of battery manufacturers cannot meet the conditions. In general, the consistency of the battery does not reach the level of the 18650 battery. If the consistency of the battery fails to meet the requirements, the management of a large number of battery strings and battery packs formed in parallel will not allow the performance of each battery to be better played, and 18650 batteries can solve this problem well.

——High safety performance:

The 18650 lithium-ion battery has high safety performance, no explosion, no combustion; non-toxic, non-polluting, and has passed RoHS trademark certification; and has good high temperature resistance, and the discharge efficiency is 100% under the condition of 65 degrees.

The 18650 battery is generally packaged in a steel shell. In extreme situations such as a car collision, it can reduce the occurrence of safety accidents as much as possible, and the safety is higher. In addition, the size of each battery cell of the 18650 is small, and the energy of each cell can be controlled in a smaller range. Compared with the use of large-size battery cells, even if a unit of the battery pack fails, it can be reduced The impact of the failure.

——High energy density:

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

——Low cost and high cost performance:

The 18650 lithium-ion battery has a very long service life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. The 18650 product has a high degree of technological maturity. The structural design, manufacturing technology, and manufacturing equipment, as well as the derived 18650 module technology are all mature, all of which reduce its operating and maintenance costs.
