1. Durability: lithium iron phosphate battery has strong durability, slow consumption, more than 1000 times of charging and discharging, and no memory. The general service life is 5-8 years.
2. Discharge rate: lithium iron phosphate battery can discharge at high current, which is suitable for solar street lamps, electric vehicles, electric bicycles, etc.
2. Volume and quality: the volume of lithium battery is relatively small.
3. Battery capacity: the capacity of lithium battery in the same volume is larger than that of lead-acid battery. The capacity of lead-acid battery is about 20 A; Lithium battery capacity is 8-10a.
4. No memory effect: lithium iron phosphate battery can be used with charging no matter what state it is in, and there is no need to discharge it before charging.
5. Nominal voltage of monomer: lithium iron phosphate nominal voltage of monomer: 3.6V.
6. Environmental protection: lithium material has no toxic and harmful substances. It is considered a green battery in the world. The battery has no pollution in production and use, and has become a research hotspot.
7. Safety: lithium iron phosphate has passed strict safety test and will not explode even in the worst traffic accidents, showing higher safety performance.
Advantages of lead-acid battery:
1. Lead acid batteries generally have deep charge and deep discharge less than 300 times, have memory and a service life of about two years. And there is liquid in the lead-acid battery. After consumption for a period of time, if the battery is hot or the charging time becomes shorter, it is necessary to supplement the liquid.
2. Generally, the weight of lead-acid battery is 16-30kg and the volume is large;
3. There is a large amount of lead in lead-acid batteries, which will pollute the environment if it is not handled properly after being discarded
4. Nominal voltage of lead-acid battery: 2.0V, and the voltage of an ordinary lead-acid battery is usually 12V.
Lithium iron phosphate battery has many advantages over lead-acid battery:
1. Large capacity. The monomer can be made into 5Ah ~ 1000ah (1Ah = 1000mah), while the 2V monomer of lead-acid battery is usually 100Ah ~ 150Ah, with a small variation range.
2. Light weight. The volume of lithium iron phosphate battery with the same capacity is 2 / 3 of the volume of lead-acid battery and 1 / 3 of the weight of the latter.
3. Strong fast charging capacity. The starting current of lithium iron phosphate battery can reach 2c to realize large rate charging; The current of lead-acid battery is generally required to be between 0.1C ~ 0.2C, which can not achieve fast charging performance.
4. Environmental protection. Lead acid batteries contain a large amount of heavy metals - lead, resulting in waste liquid, while lithium iron phosphate batteries do not contain any heavy metals and are pollution-free in production and use.
5. High cost performance. Although the purchase cost of lead-acid battery is lower than that of lithium iron phosphate battery because of its cheap material, it is less economical than lithium iron phosphate battery in service life and daily maintenance. The practical application results show that the cost performance of lithium iron phosphate battery is more than 4 times that of lead-acid battery.
