Eight advantages of 18650 lithium battery

Advantages and disadvantages of 18650 lithium battery The 18650 battery is cylindrical with liquid inside. Due to battery planning and material reasons, 18650 is suitable for high current. Therefore, almost all notebook computers and electric vehicles use the 18650 battery plan. There are only super notebooks. Because of energy saving, 18650 batteries cannot be used instead of lithium polymer batteries, especially tablet computers. Digital cameras can only use batteries similar to 18650. Due to the large voltage and instantaneous large current required for charging and discharging, they only have Small size; advantages of 18650 lithium battery: 1. The capacity of large-capacity 18650 lithium battery is generally between 1200mah~3600mah, while the general battery capacity is only about 800. Assuming the combination of 18650 lithium battery packs, 18650 lithium battery packs are perfunctory It can break through 5000mah. 2. Long life 18650 lithium battery has a long service life. The normal service life can reach more than 500 times, which is more than twice that of ordinary batteries. 3. High safety function 18650 lithium battery has high safety performance, no explosion, no burning; non-toxic, non-polluting, RoHS trademark certification; multiple safety functions, more than 500 cycles; high temperature resistance performance, 65 degrees power supply reduced to 100% . In order to prevent short circuits, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the possibility of its short circuit has been reduced to the limit. You can add a protective plate to prevent the battery from being overcharged and placed, which can extend the life of the battery. 4. The voltage of high-voltage 18650 lithium battery is generally 3.6v, 3.8v, 4.2v, which is much higher than the 1.2v voltage of nickel-cadmium batteries and nickel-hydrogen batteries. 5. There is no recall effect, the remaining power is not released before charging, and it is convenient to use. 6. Small internal resistance: The internal resistance of polymer batteries is smaller than that of liquid batteries, and the internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces battery power consumption and prolongs the standby time of mobile phones, which can reach international standards. Lithium polymer that supports large discharge current is an ideal choice for remote control mode, and is the most promising product to replace Ni-MH batteries. 7. Can 18650 lithium batteries be synthesized in series and parallel. 8. The planned wide range of applications: notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, airplane models, toys, video cameras, digital cameras and other electronic devices as important components of the lithium battery family In part, 18650 batteries were widely used in consumer electronics in the early days. In recent years, with the strong rise of new energy vehicles, 18650 batteries have also been used for the first time in new energy vehicles. In addition to the time-honored Tesla, now also including Porsche and domestic JAC, Zotye, Changan, Guangzhou Automobile and other confused models have joined the 18650 battery research and development force. Industry insiders said that in the future, more models will fall in love with 18650 batteries, which will promote subversive changes in the use of 18650 batteries. The 18650 battery has obvious advantages. Japanese manufacturers have accumulated a lot of relevant experience in the processing of the 18650 battery, and achieved relatively high consistency and safety, which is called the 'benchmark'. Luo Huiming, deputy secretary-general of my country’s Micro Electric Vehicle Industry Technology Innovation Alliance, said that this is why Tesla chose Japan’s 18650 battery. Deng Lunhao, general manager of Guangxi Zhuoneng New Energy Technology Co., Ltd. also mentioned: Because the 18650 battery has a high degree of automation, good stability, and high replaceability, the 18650 battery has unparalleled modularity and standardization in system development. Common advantages. It can effectively reduce processing costs and save labor. In terms of energy density, ModelS uses 18650 batteries with an energy density of approximately 252Wh/kg, 3.1Ah. Toyota Leaf’s soft-pack battery is 33Ah, and the energy density of a single battery is 150Wh/kg. Obviously, the 18650 battery is superior to the soft pack battery in terms of energy density. Therefore, the 18650 battery has great advantages, especially in mini-electric vehicles. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
