The 18650 lithium-ion battery can be used in:
1. Energy storage, mainly used in base station power supply, clean energy storage, grid energy storage, home optical storage system, etc.
2. The Power category mainly refers to electric vehicles, electric bicycles, new energy vehicles, etc.
3. Digital, mobile phones, tablets, laptops, electric toys, Mp3/Mp.
4. Headphones, power banks, model airplanes, mobile power supplies, etc.
What does the mark DI52021MCBG0209 mean on lithium battery?
The ICR of 18650 battery is better than INR. Both the 18650 ICR and IR batteries are lithium-ion batteries with a voltage of 3.7V, but the hardware system is different. The battery capacity level of inr is 1000, while the capacity level of batterie of icr is 2000, so 18650 icr battery is better than inr.
Generally, the following codes are printed on the lithium battery cells
1: The material identification code is usually printed on the printed terminal part of the battery, such as ICR, IMR, NCR, IFR, LTO, etc. So what do these spray codes mean? ICR: Lithium cobalt oxide is used as cathode material. IMR: The cathode material uses lithium manganate. NCR: The material of the positive electrode is lithium-nickel-cobalt manganate (commonly known as ternary). IFR: The cathode material uses lithium iron phosphate. LTO: The cathode material uses lithium titanate. Based on this, you can understand what the cathode material of lithium batteries is and avoid being deceived by traders.
2: Specification number The specification model iThis usually refers to the size of the lithium battery, such as: 18650 (18/65), 18490 (18/49), 21700 (21/70), 26650 (26/65), 32650 (32/65). ), etc. The first two numbers represent the diameter of the battery, the last two numbers represent the length (some people like to call it height), and 0 represents the cylinder. For example, 18650 refers to a cylindrical battery with a diameter of 18mm and a length of 65mm. The power type will also add the maximum discharge power after the model inkjet code, such as 18650/3C, 18650/5C, etc., which means the maximum discharge current can reach multiple of its own 3C capacity refers to 3 times. , like the 3C multiple of 1500mAH. The discharge current can reach 4.5A. Ordinary Logo 18650
3: Capacity and voltage printing will mark the battery capacity and power, such as: 1800 mAh, 2000 mAh, 2200 mAh, 2400 mAh, 2500mAh, 2600mAh, etc. are common for 18650 batteries. are the capacities of the battery, some manufacturers will also spray the corresponding power capacity on the battery. For example, the power of 3.7V 18650 1800mAh battery is 6.6Wh. Some unscrupulous traders on Taobao take advantage of customers' lack of understanding of batteries and deliberately sell energy in the form of capacity, such as 4000MWh 18650 battery and 6000MWh 18.650 battery or even 9000mwh battery 18650. In fact, to convert, for a 3.7V 18650 battery, use mwh÷3.7V=mAh. The actual capacity of 18650 with 4000 MWh is 1081 mah. Everyone should keep their eyes open when purchasing batteries and not be deceived by unscrupulous traders.
The voltage code refers to the voltage of a single battery. Different materials have different positive electrode voltages, such as lith manganateium (3.6 VIMR), lithium cobalt oxide (3.7 V/3.8 VICR), lithium nickel cobalt. Manganate (commonly known as three Yuan, 3.6 VNCR), lithium iron phosphate (3.2 VIFR), lithium titanate (2.3 V/2.4 VLTO). Some manufacturers mark the full power voltage and some manufacturers mark the rated voltage. Different manufacturers have different voltage marking methods.
4: Production batch code Each manufacturer's production batch code is different. Approximate contents correspond to year and month of production. Knowing the manufacturer's batch code can help you understand when the battery was produced. I won't have any old batteries. 5: Manufacturer's Brand Logo Many manufacturers will mark the manufacturer on the battery, including the manufacturer's LOGO and brand words. The printing code of each manufacturer is different, so the manufacturer's logo is also different.
