What Is The Difference Between Lithium Iron Phosphate Batteries And Lead-Acid Batteries?

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

1. Volume: The lead-acid battery is relatively large, generally 15-30kg, while 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 batteries is 3-4 times higher than that of nickel-cadmium batteries, 2.5 times higher than that of nickel-cadmium batteries, and 1.8 times higher than that of nickel-cadmium batteries.

3. Service life: lead-acid batteries can reach 300 cycles, and can be charged and discharged at room temperature at 1 degree Celsius. After 2000 cycles, the battery capacity is still greater than 80%, and the life of 3C batteries can reach 800 cycles. Acid batteries have high requirements on ambient temperature. In extreme environments, their service life will not exceed 5 years. Under the same working conditions, lithium iron phosphate has a longer service life.

4. Safety: Under severe impact, lead-acid batteries will explode, endangering the lives of users; lithium iron phosphate batteries fully meet the safety requirements for lithium cobalt oxide batteries and lithium manganese oxide batteries, even under intense impact There will be no explosion on impact.

5. Temperature: The working environment of the lead-acid battery is -20 degrees Celsius to 50 degrees Celsius, and has a low Selfie ability. The maximum heat energy of the lithium iron phosphate battery pack reaches 350-500 degrees Celsius, and it can still release 100% of the heat under higher temperature conditions.

6. Charging efficiency: Lead-acid battery, under normal charging state, the charging time is 8-10 hours. Because of its own material and electrolyte, it can be charged quickly, and it can be charged and discharged quickly under 2C high current. Use a special charger 1.5C to charge for 40 minutes.

7. No memory effect: lead-acid batteries have a memory effect. The working state of rechargeable batteries is often full, and the capacity will drop soon if they are not fully released. This is not the case with lithium iron phosphate batteries, which can be used at any time no matter what the situation is.

8. Green and environmental protection: Lead-acid batteries contain high lead content, which will cause environmental pollution if not disposed of properly. Lithium iron phosphate is a non-toxic substance and is a green and environmentally friendly battery.

9. Use and maintenance: Since there are certain problems in the use and maintenance of lead-acid batteries, frequent maintenance is required, and maintenance costs will increase accordingly. The lithium iron phosphate battery, because of its good stability, does not require frequent maintenance.

With the development of residents' living standards and the improvement of science and technology, most manufacturers of lithium iron phosphate batteries are gradually getting rid of the "backward equipment" handheld laser welding machines, and gradually replace handheld welding machines with laser welding machines.

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