26650 battery cell this battery with excellent capacity and high consistency and other characteristics, has gradually become a replacement for 18650 battery trend, in the power battery many products will gradually favor this.
26650 lithium battery is a type specification of cylindrical lithium battery. Mainly used in electric tools, car recorders, lighting, wind energy storage, electric cars, toys, instruments and meters, ups backup power supply, communication equipment, medical equipment and military industry and other fields. The definition of its model law: 26650 type, that is, the diameter of the battery is 26mm, the length of 65mm, cylinder type battery. Generally used to refer to lithium batteries, including lithium primary batteries and lithium ion batteries.
The life of a 26650 lithium battery is typically 300-500 charge cycles. Assuming that a complete discharge provides 1Q of power, if the decrease in power after each charging cycle is not taken into account, the Li-ion battery can provide or replenish a total of 300Q-500Q of power during its lifetime.
The maximum capacity of 26650 lithium batteries is usually between 5000 milliampere hours (mAh) and 7000 milliampere hours (mAh). With the continuous development of lithium battery technology, new high-capacity lithium batteries will appear in the future.
1.Features and application scenarios of 26650 lithium battery
Capacity and Endurance: 26650 Li-ion batteries usually have higher capacity, for example, the nominal capacity of BATTSYS is 4000mAh, which gives it an advantage in providing long endurance.
Applications: Due to its larger size and higher capacity, 26650 Li-ion batteries are suitable for applications that require high energy density, such as power tools, lighting equipment, wind energy storage systems, solar street lights, etc.
Safety: 26650 lithium batteries have overcharge and overdischarge protection, as well as better resistance to external short circuits, ensuring the safety of use.
2.Features and application scenarios of 21700 lithium batteries
Size and portability: The size of 21700 Li-ion battery is between 18650 and 26650, providing a better volumetric energy density, suitable for applications that require medium capacity and want the battery size not to be too large.
Capacity: The nominal capacity of 21700 Li-ion batteries is usually between 3000mAh and 5000mAh, depending on the battery technology and manufacturer.
Applications: Due to its moderate size and capacity, 21700 Li-ion batteries are suitable for applications requiring medium energy density and smaller size, such as laptop computers, high-end flashlights and portable medical devices.
1, battery volume comparison: 26650 lithium battery volume than 18650 lithium battery volume, their core height is the same, the core diameter is different, 26650 lithium battery core diameter of 26mm, while 18650 lithium battery core diameter of 18mm.
2, the battery rated capacity comparison: the same battery material 26650 battery capacity than the 18650 battery capacity to be larger, assuming the same ternary material, 26650 battery rated capacity is generally around 5200mAh, while the 18650 battery capacity is more 2600mAh or so.
3, the application environment comparison: 18650 lithium batteries used in lighting lamps and lanterns batteries, industrial supporting lithium battery packs, electric tool batteries, electric bicycle batteries, power lithium battery packs, etc., and 26650 lithium batteries used in the integration of lithium battery packs of solar street lamps, energy storage stations, solar energy storage batteries, etc. more.
26650 lithium batteries vs 18650, which is stronger?
For 18650 lithium batteries and 26650 lithium batteries which one is stronger, it is unlikely to be very clear at once, but also depends on which kind of rechargeable battery you want to use. For example, 18650 lithium batteries are used in lighting equipment rechargeable batteries, industrial production auxiliary lithium battery packs, pneumatic tool rechargeable batteries, electric vehicle rechargeable batteries, power lithium battery packs, etc., and 26650 lithium batteries are used in the integrated solar lamp lithium battery packs, energy storage stations, energy storage, and so on.
