Lithium iron phosphate battery seven advantages

Lithium iron phosphate battery seven advantages

(1) long life

Long life lead-acid battery cycle life of about 300 times, the highest also 500 times, while the lithium iron phosphate battery, the cycle life of more than 2000 times, the standard charge (5h rate) use, up to 2000 times. With the quality of the lead-acid battery is the "new half year, the old half year, maintenance and maintenance half a year", up to 1 ~ 1.5 years, and lithium iron phosphate batteries in the same conditions, will reach 7 to 8 years. Taking into account, the performance and price ratio will be more than 4 times the lead-acid battery. Figure 2 shows the relationship between the capacity and the number of cycles of the FP053450A lithium iron phosphate battery. As can be seen from the figure, when the number of cycles is more than 2000, it is still possible to charge nearly 90% of the nominal capacity.


(2) the use of security

Lithium iron phosphate battery completely solve the lithium cobalt oxide battery and lithium manganese battery safety problems, lithium cobalt oxide batteries and lithium manganese batteries in a strong collision will produce an explosion, the safety of consumers posing a threat. The lithium iron phosphate battery to undergo a rigorous safety test, even in the worst traffic accidents will not produce an explosion.


(3) can be high current rapid charge and discharge

In the special charger, 1.5C charge 40min can make the battery is full, starting current up to 2C, and lead-acid battery now no such performance. Figure 3 shows the discharge characteristics of a certain type of lithium iron phosphate battery at different discharge rates. The minimum discharge rate given in the figure is 0.2C and the maximum discharge rate is 10C. Six different discharge rates form a set of discharge curves. It can be seen from the figure, regardless of which discharge rate, the discharge process that the discharge voltage is stable, basically remain the same, only to the end of the discharge voltage, the curve was bent down, the discharge capacity of 2000mAh only after the downward Bending, at 2500mAh, the curve has obvious bending. In the discharge range of 0.2 ~ l0C, the output voltage is mostly in the range of 2.7 ~ 3.2V. This shows that the electric he has a very good discharge characteristics.


The discharge curve of a lithium iron phosphate battery with a model capacity of about 5500 mAh at different temperatures (from -20 ° C to + 60 ° C) is shown in Fig. If the discharge capacity at 25'C is I00%, the discharge capacity is slightly greater than 100% when the temperature is higher than 40 ℃, and the discharge capacity decreases when the temperature is lower than 25 ℃, and the discharge capacity decreases at -20 ℃ To 50%.


(4) high temperature
Wide operating temperature range (-20 ℃ ~ 75 ℃), high temperature characteristics. Lithium iron phosphate battery heating peak up to 350 ℃ ~ 500 ℃, while the lithium manganese oxide battery and cobalt acid battery electric heating peak only about 200 ℃.
(5) large capacity

The voltage level of the battery used in the communication industry is 12V; the voltage level of the battery pack is 24V, 48V and the DC power supply system is 24V, 36V, 48V, 96V, 240V , 384V, etc .; commonly used battery capacity level from 25Ah, 65Ah, 100Ah, 150Ah, 200Ah, 500Ah, 1000Ah range. Click to view the company's various large-capacity lithium iron phosphate battery outline. By setting the 12V or 48V battery modules in series, 240V, 336V, 384V battery packs can be used to meet the power supply requirements of the UPS AC power supply system and the 240V / 336V high voltage DC power supply system (HVDC).


(6) no memory effect

Rechargeable batteries are often filled with conditions of work, the capacity will quickly lower than the rated capacity value, this phenomenon is called the memory effect. Like nickel-metal hydride, nickel-cadmium batteries exist memory, and lithium iron phosphate battery without this phenomenon, regardless of what state in the battery, with the charge with the use, no need to put the first charge and then recharge.


(7) green
Lithium iron phosphate battery does not contain any heavy metals and rare metals (nickel-metal hydride batteries need rare metals). Non-toxic (SGS certified), non-polluting, in line with European RoHS regulations, for the absolute green battery. Lead-acid batteries in a large number of lead, after its disposal if improper handling, the secondary pollution of the environment, and lithium iron phosphate materials in the production and use of no pollution, so lithium iron phosphate batteries are listed as "fifteen "Period of" 863 "national high-tech development plan, become a national key support and encourage the development of the project.
