What is the difference between lithium iron phosphate and lead-acid batteries?

1. Volume: the volume of the lead-acid battery is relatively large, generally 15-30kg, and the lithium iron phosphate battery is relatively small, usually 2.5-3.0kg.

2. Energy density ratio: the energy density ratio of lithium iron phosphate battery is 3-4 times, 2.5 times higher than nickel cadmium battery, and 1.8 times higher than nickel cadmium battery.

3. Service life: Lead-acid battery can be up to 300 cycles, can be charged and discharged at room temperature of 1 degree Celsius, can be in 2000 cycles, the capacity of the battery is still more than 80%, the life of 3C battery can be up to 800 times, lead-acid battery has a high requirement for environmental temperature, in extreme environments, its service life will not exceed 5 years, lithium iron phosphate in the same working condition, Its service life is also longer.

4. Safety: under the intense impact, the lead-acid battery will explode, endangering the life of the user; Lithium iron phosphate batteries fully meet the safety requirements of lithium cobalt acid batteries and lithium manganese acid batteries, even in a violent impact will not explode.

5. Temperature: The working environment of the lead-acid battery is -20 degrees Celsius to 50 degrees Celsius, which has a low self-shooting ability. Lithium iron phosphate battery packs have a maximum thermal energy of 350-500 degrees Celsius, and can still release 100% of the heat at higher temperatures.

6. Charging efficiency: lead-acid battery, normal charging state, charging time is 8-10 hours, because of its own material and electrolyte is good, so it can be charged quickly, can be in 2C large current for rapid charging and discharging, using a special charger 1.5C charging for 40 minutes.

7. No memory effect: lead acid battery has a memory effect, the working state of the rechargeable battery is often full, not completely released, the capacity will soon decline. Lithium iron phosphate batteries do not have this situation, no matter what the situation, can be used at any time.

8. Green environmental protection: the lead content in lead-acid batteries is high. If disposed improperly, it will cause environmental pollution. Lithium iron phosphate is a non-toxic substance, is a green, environmentally friendly battery.

9. Use and maintenance: Due to some problems in the use and maintenance of lead-acid batteries, frequent maintenance is required, and the maintenance cost will be increased accordingly. The lithium iron phosphate battery, because of its good stability, so it does not need frequent maintenance.

With the development of residents' living standards and the improvement of scientific and technological levels, now most of the manufacturers of lithium iron phosphate batteries have gradually got rid of the "backward equipment" handheld laser welding machine, and gradually replaced the handheld welding machine with laser welding machine.

A good laser welding machine can not only improve the welding quality of lithium iron phosphate battery, but also be more efficient than handheld laser welding machine.
