Which is better between 26650 lithium ion battery and 18650 lithium ion battery

Comparison of 26650 lithium ion battery and 18650 lithium ion battery ●Battery volume comparison 26650 lithium ion battery is larger than 18650 lithium ion battery. They have the same cell height but different cell diameter. The 26650 lithium ion battery cell diameter is 26mm , And 18650 lithium ion battery cell diameter is 18mm. ●Battery capacity comparison The 26650 battery capacity under the same battery material is larger than the 18650 battery capacity. Assuming that the same ternary material 26650 battery is generally around 5200mAh, the 18650 battery capacity is mostly around 2600mAh. ●Comparison of application environment 18650 lithium ion batteries are used in lighting lamps batteries, industrial supporting lithium ion battery packs, power tool batteries, electric bicycle batteries, power lithium ion battery packs, etc., while 26650 lithium ion batteries are used in integrated solar street lights Lithium-ion battery packs, energy storage stations, solar energy storage batteries, etc. are more. ●The rated capacity of IFR26650 is 3000mAh, and the rated capacity of IFR18650 is 1100~1400mAh. ●Different battery capacity The capacity of the 26650 lithium-ion battery under the same battery material is larger than that of the 18650 battery. Assuming that the same ternary material 26650 battery is generally around 5200mAh, the capacity of the 18650 battery is mostly around 2600mAh. Advantages of 26650 lithium-ion battery over 18650 lithium-ion battery 1. Higher monomer capacity. The current mainstream domestic ternary system 18650 lithium-ion battery is usually 2900-300mAh, so the capacity advantage of 26650 lithium-ion battery is obvious. 2. Lower cost Due to the increase in volume, structural changes and other reasons, some lithium-ion battery auxiliary materials are used less, and the cost of raw materials will be reduced partly. The processing efficiency of battery cells is also higher than that of 18650 lithium-ion batteries. In terms of the cost of lithium-ion battery packs, because the battery packs of the same capacity use fewer single 26650 lithium-ion batteries, no matter in terms of structural accessories and battery management system (BMS), the management difficulty is reduced. Can save costs. 3. Smaller space. Because the number of 26650 lithium-ion batteries used in the battery pack is reduced, the overall volume of the battery pack will also decrease after offsetting some factors that increase the diameter.
