1.26650 lithium batteries have overcharge performance
After standard charging, measure the initial state of the battery. When the battery state is normal, charge with 3C current to 10.0 volts, then charge to constant voltage until the current is 0.01 degrees Celsius . Observe changes in the appearance of the battery. Result: no fire or explosion.
2.26650 Li-ion battery has over-discharge performance
After standard charging, measure the initial state of the battery. When the battery is in normal state, discharge it to 0 V at 0.5 C. Observe the changes in the appearance of the battery. Result: No fire or explosion.
3. Hard to short-circuit outside
After standard charging, measure the initial state of the battery, put it into the explosion-proof cover, so that the positive and negative terminals are directly short-circuited (the total resistance of the circuit is not greater than 50m). When the battery temperature drops to about 10 lower than the peak temperature, the test ends. Observe the temperature and appearance changes of the battery. Result: No fire or explosion.
To directly say 18650 lithium batteries and 26650 lithium batteries which battery is good, it is not possible to compare the relative out at once, but also depends on what you want to use in what field. For example, 18650 lithium batteries used in lighting batteries, industrial supporting lithium battery packs, electric tool batteries, electric bicycle batteries, power lithium battery packs, etc., and 26650 lithium batteries used in integrated solar street lamps lithium battery packs, energy storage stations, solar energy storage batteries, etc., more.
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, battery capacity comparison: the same battery material 26650 battery capacity than the 18650 battery capacity, assuming that the same ternary material 26650 battery is generally about 5200mAh, while the 18650 battery capacity is more than 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.
The nominal capacity of 26650 Li-ion battery is 3300mAh (capacity range 3300-4650mAh), so the maximum capacity of 26650 Li-ion battery is 4650mAh.
The life of 26650 cells is typically in the range of 300-500 charge cycles. This means that the cells can be fully charged and discharged in this range for 300 to 500 operations, after which the performance of the cells may gradually degrade.
26650 cells are larger than 21700 cells. The 26650 cell has a diameter of 26mm and a height of 65mm, whereas the 21700 cell has a diameter of 21mm and a height of 70mm. 26650 cells are therefore significantly larger than 21700 cells in terms of size12. Capacity and Energy Density Comparison Capacity: The nominal capacity of the 26650 battery is 3200mAh, while the nominal capacity of the 21700 battery is twice that of the 18650 battery. The specific value is not given, but it can be assumed that its capacity is also relatively high1. Energy density: The volumetric energy density of the 21700 battery is as high as 170 Watt-hours per kilogram, which is much higher than that of the 18650 type battery, which means that under the same weight, the 21700 battery can provide a higher energy output.
26650 lithium batteries are mainly divided into ternary materials and lithium iron phosphate materials, and ternary materials 26650 lithium batteries fully charged voltage of 4.2V, lithium iron phosphate 26650 lithium batteries fully charged voltage of 3.65V; so 26650 lithium batteries the minimum use of the voltage to be determined by the application.
26650 Li-ion batteries typically have a life expectancy of 300-500 battery charge cycle times. Used for lighting, 5 days to 10 days or so time is about the same, this also look at the lighting you use the wattage is how big, it's power consumption is not big, if his wattage when I am relatively large, power consumption is also relatively large, basically lighting 5 days or so time may not have electricity if the wattage of the lighting is relatively low, the consumption of power is not very large with 10 days or so is possible.
The service life of Li-FePO4 battery depends on many factors, such as charging and discharging environment conditions, charging and discharging times, using temperature and so on. Generally speaking, its service life can reach between several years and ten years, while the actual service life also depends on the specific situation.
