18650 lithium battery price, 18650 lithium battery price trend analysis

Introduction to 18650 lithium battery 18650 is the originator of lithium ion battery-a standard lithium ion battery model set by SONY in Japan in order to save costs. The numbers of 18650 in 18650 lithium battery represent the appearance size: 18 indicates a diameter of 18mm, 65 indicates a length of 65mm, and 0 indicates a cylindrical battery. Common 18650 batteries are divided into lithium-ion batteries, lithium iron phosphate and nickel-metal hydride batteries. The voltage and capacity specifications are nickel-metal hydride battery voltage of 1.2V, common capacity is 2500MAH, and lithium-ion battery voltage of 3.6V, common capacity is 1500MAH-3100MAH. 18650 battery performance knowledge 1. Usage: Because of the large capacity of the unit density, it is often used for most of the notebook batteries. In addition, it is also often used for high-end glare flashlights, portable power supplies (mobile chargers), etc. . 2. Size: The numbers 18650 represent the appearance size: 18 refers to the battery diameter of 18.0mm and 650 refers to the battery height of 65.0mm. (Our ordinary No. 5 battery [AA battery], size is 14500) 3. Type: 18650 batteries have lithium ion batteries and nickel-hydrogen batteries. Since nickel-hydrogen batteries are rarely used now, we are now talking about 18650 batteries without special instructions. Yes, it is a batch of 18650 lithium-ion batteries. 4. Voltage and capacity specifications: Ni-MH battery voltage is 1.2V, common capacity is 4500MAH, lithium ion battery voltage is 3.6V-3.7, common capacity is 1500MAH-2600MAH, and the current maximum capacity is 3000MAH. The 18650 lithium ion battery has great advantages over the commonly used AA battery in terms of weight, volume, and capacity. For example, a 2400MAH 18650 battery, the voltage is calculated according to the standard 3.7V, and the power is 8880MWH. The best Sanyo No. 5 rechargeable battery ENELOOp has a capacity of 2000MAH, a voltage of 1.2V, and a power of 2400MWH. It can be seen that a good 18650 battery has a power capacity close to 4 times that of the No. 5 battery. Advantages of 18650 lithium battery 1. Large capacity The capacity of 18650 lithium battery is generally between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the 18650 lithium battery pack can break through casually 5000mah. 2. Long life The 18650 lithium battery has a long life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 3. High safety performance 18650 lithium battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; various safety performances can be achieved in one go, and the number of cycles is greater than 500; high temperature resistance performance, under 65 degrees The discharge efficiency reaches 100%. In order to prevent the battery from short-circuiting, 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 avoid overcharging and overdischarging the battery, which can also extend the battery life. 4. High voltage. The voltage of 18650 lithium battery is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries. 5. No memory effect. It is not necessary to empty the remaining power before charging, which is convenient to use. 6. Small internal resistance: The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of domestic polymer batteries can even be below 35mΩ, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. In time, it 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. 7. It can be combined in series or parallel to form a 18650 lithium battery pack. 8. A wide range of 18650 lithium battery applications. 1. Energy storage is mainly used in base station power supplies, clean energy storage, grid power storage, household solar storage systems, etc. 2. Power category mainly refers to electric vehicles, electric bicycles, new energy vehicles, etc. 3. Digital mobile phones, tablets, laptops, electric toys, Mp3/Mp4, earphones, power banks, model airplanes, mobile power supplies, etc. The price of 18650 lithium battery is judged. The factory price of 18650 battery is calculated per 1000mAh. The ex-factory price is 3.6/4.0/6.0 yuan per 1000mAh, and the market price is about 8 yuan 18650. Throw away the profits of the merchants and then the profits of the wholesalers. The single battery is generally around 3.2, and the actual capacity is around 800mAh. .
