Advantages:
The biggest advantage is the long service life. The number of charging and discharging times of the iron lithium battery can reach 1200 times, and it can be used for about 3-5 years; The number of lead-acid battery charging and discharging times is about 300 times, and it can generally only be used for 1-2 years.
3. Lithium iron No. 1 has non-activation properties and has a memory effect. Lithium batteries are easy to activate. After 3-5 normal charge and discharge cycles, the battery can be activated and restored to its normal capacity.
4. Compared to lead-acid batteries, lithium batteries have a higher average voltage and higher energy density. In other words, for batteries of the same size, lithium batteries have. more capacity.
5. Lithium-ion batteries for electric bicycles can functionner in the range of -25 degrees to 55 degrees, and their electrical capacity can reach 70% of the rated capacity, while lead-acid batteries can only work in the range of 10 degrees to 40 degrees and do not work properly at -25 degrees.
6. The lithium battery has a short charging time and is green and environmentally friendly. Since the lithium-ion battery of an electric bicycle can be charged with high current, the charging time is only 4-5 hours.
Disadvantages of Lithium Iron One
1. The price of Lithium Iron One is too high due to the battery lithium iron. The power of lithium batteries needs to be improved. Compared to lead-acid batteries, lithium batteries are much less resistant to charge and discharge fluctuations. This is a major symptom of the inability to effectively use lithium batteries in vehiclescurrent high power. resulting in reduced durability.
2. Security and stability are relatively poor. If not used correctly, a risk of explosion can easily occur. Additionally, lithium batteries cannot be discharged at high currents and require high production conditions and higher costs.
3. Compared with lithium batteries, lead-acid batteries are relatively cheap and easier to accept by the public. In addition, lead-acid batteries have better high-rate discharge performance. The most important thing is that the recycling price of lead-acid batteries is higher than that of lithium batteries.
4. Charging the lithium battery for too long is counterproductive. The lithium battery or charger will automatically stop charging once the battery is full. There is no so-called continuous load. baNickel batteries for over 10 hours of trickle charging.
It can be used.
The performance of lithium iron phosphate will gradually decrease below zero. Lithium titanate is recommended, which can be charged and discharged normally at minus 40°C in winter, and its performance is not much different from that at 40°C above zero. The cell voltage, 3.2 ~ 3.3 V (nominal and temperature-related voltage) is lower than this value, indicating the need for charging. Above this voltage, continuous charging will cause the voltage to rise rapidly. full The highest voltage is 3.9V alone.
During discharge, the voltage drops quickly from 3.9 V to 3.2 V and remains stable until the discharge ends. At the end, the voltage quickly drops to 3.2V. At present, the electricity can be considered to be running out.
Lithium iron phosphate battery
The dulife is closely linked to its operating temperature. If the operating temperature is too low or too high, it will cause great hidden dangers during its charging, discharging and using process. Especially when used in electric vehicles in northern China, lithium iron phosphate batteries cannot provide normal power or the power supply is too low in autumn and winter, and the temperature of the working environment must be adjusted to maintain its performance. Home solutions to the constant temperature working environment of lithium iron phosphate batteries must consider space constraints. The most common solution is to use airgel felt as an insulation layer.
