Panasonic 18650 lithium battery is better than Samsung 18650 lithium battery?

Panasonic 18650 lithium battery: Tesla is currently the best electric car in the world, with performance that is not inferior to that of a traditional fuel car. In addition to electric motor technology, one of Tesla's core technologies is its advanced battery technology. Demystifying the Tesla battery, foreign experts once disassembled the battery panel of a ModelS. The Tesla battery pack is placed on the chassis between the front and rear axles, and its weight can reach 900 kg. The battery pack is composed of more than 7,000 18650 lithium batteries. The Panasonic 18650 lithium battery used by Tesla uses NCA as the positive electrode and has designed a complex battery management system to ensure and improve the efficiency and safety of battery work as much as possible. As for whether it is absolutely safe or not, this cannot be answered. If you want to talk about spontaneous combustion, I would also like to say that gasoline cars also spontaneously ignite in summer. The price of 10 series-connected Panasonic 18650 lithium batteries A high-quality 18650 lithium battery costs more than ten yuan. The common capacity is also 2000-2600, and the price is about 25-40. Panasonic is currently able to purchase a maximum capacity of 3000. Panasonic's 18650 lithium battery has a long service life, with a cycle life of more than 500 times during normal use, which is more than twice that of ordinary batteries. Panasonic 18650 lithium battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; various safety performances are completed in one go, and the number of cycles is greater than 500; high temperature resistance performance is good, and the discharge efficiency can reach 100 at 65 degrees. %. In order to guard against the battery short-circuit phenomenon, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to guard against overcharge and overdischarge of the battery, which can also extend the battery life. Samsung 18650 lithium battery: Samsung 18650 lithium battery has low internal resistance and good quality. The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. At present, the internal resistance of domestic polymer batteries can even be less than 35m, which is extremely large. It reduces the self-consumption of the battery and prolongs the standby time of the mobile phone, which can fully meet the international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace nickel-hydrogen batteries. Due to the fixed size of the Samsung 18650 battery, its maximum capacity has always been concerned by many practitioners. In recent years, various manufacturers have improved their technology and the capacity has increased accordingly. Samsung, Panasonic, LG, Sony, and Toshiba can achieve more than 3600mAh , But the best stability and consistency is the capacity range of 2600~3000mAh. If it is a battery pack, it is best not to use the highest capacity, regardless of the cost performance and the service life of the battery pack after being assembled, it is not very cost-effective. The higher the capacity, the more stable it is and the longer it will last. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
