What is the difference between 18650 lithium battery and 26650.
To directly determine which battery is better, 18650 lithium battery or 26650 lithium battery, it is impossible to compare them all at once. It also depends on what field you want to use them in. For example, 1865 lithium batteries are widely used in lighting fixture batteries, industrial supporting lithium battery packs, power tool batteries, electric bicycle batteries, power lithium battery packs, etc., while 26650 lithium batteries are widely used in integrated solar street light lithium battery packs, energy storage stations, solar energy storage batteries, etc.
What is 26650 lithium battery
26650 lithium battery is a type and specification of cylindrical lithium battery. Used in the fields of electric tools, lighting, wind and solar energy storage, electric vehicles, toys, instruments and meters, UPS backup power supply, communication equipment, medical equipment, and military lighting. The definition of its model is: 26650 type, which refers to a cylindrical battery with a diameter of 26mm and a length of 65mm (as shown in the figure). Generally used to refer to lithium batteries, including lithium primary batteries and lithium-ion batteries. Common lithium batteries made of useful nickel cobalt manganese cathode materials and lithium iron phosphate materials - INR26650-3.6V-4500mAh IFR26650-3.2V-3200mAh。
The advantages of 26650 lithium battery are that it has overcharge performance. After standard charging, the initial state of the battery is measured. When the battery is in normal condition, it is charged to 10.0V with a current of 3C, and then switched to constant voltage charging until the cut-off current is 0.01C, at which point it terminates. Observe the appearance changes of the battery. Result: No fire, no explosion.
What is the difference between 18650 and 26650 lithium batteries?
1、 Capacity difference: The 18650 lithium-ion capacity ranges from 1200mAh to 3600mAh. The capacity of 22650 lithium-ion batteries is between 3000-5000mah.
2、 Different shapes: 1850 type lithium-ion battery with a capacity of 18mm, 26650 type with a capacity of 26mm.
3、 Different reference weights: The net weight of lithium ions in 18650 and 26650 is 40g and 95-100g, respectively.
4、the capacity of 26650 is larger than that of 18650.
5、different application scenarios:
18650 lithium-ion batteries are used in lighting equipment, industrial production equipment, inflatable tools, electric vehicles, etc.
