Lithium iron phosphate: Advantages fully displayed, leading the new trend of batteries
Lithium iron phosphate(LIFEPO4 BATTERY), as an important battery material, has shown outstanding advantages in various fields in recent years, leading the new trend of the battery industry.

1. Excellent Safety Performance
1.1 The structure is stable, and it is not prone to heating or explosions even at high temperatures or overcharging. The P-O bond in lithium iron phosphate crystals is stable and difficult to decompose. This prevents lithium iron phosphate(LiFePo4) from collapsing structurally or forming highly oxidative substances like lithium cobalt oxide at high temperatures or overcharging. In practical tests such as needle puncture or short circuit experiments, only a small portion of samples showed combustion, and there have been no cases of explosions. Even in overcharging experiments, although explosions still occur when charging at significantly higher voltages than the discharge voltage, the safety of overcharging has been greatly improved compared to conventional liquid electrolyte lithium cobalt oxide batteries. This outstanding safety performance provides reliable protection for devices using lithium iron phosphate batteries, especially in fields with high safety requirements such as electric vehicles and energy storage systems, where the safety advantages of lithium iron phosphate are more prominent.

2. Long-lasting and Durable Lifespan
2.1 With a cycle life of over 4500 cycles, lithium iron phosphate(LiFePo4) batteries can last 7 to 8 years under the same weight, which is several times longer than lead-acid batteries. The cycle life of lithium iron phosphate power batteries can reach over 4500 cycles when charged under standard conditions (5-hour rate). In comparison, the cycle life of long-lasting lead-acid batteries is around 300 cycles, with a maximum of 500 cycles. Lead-acid batteries of the same weight typically last only "new half-year, old half-year, maintenance half-year," at most 1-1.5 years. In contrast, under the same conditions, lithium iron phosphate batteries can theoretically last 7-8 years. Considering performance and price, lithium iron phosphate batteries are over 4 times more cost-effective than lead-acid batteries. This long lifespan significantly reduces the cost and frequency of battery replacement in long-term use scenarios, providing users with higher economic benefits and convenience.

3. Strong High Current Discharge Performance
3.1 Lithium iron phosphate batteries(LiFePo4) can handle high currents of 2C for rapid charging and discharging, with a 1.5C charge taking only 40 minutes to complete. The starting current can reach 2C, far exceeding lead-acid batteries. High-rate lithium iron phosphate batteries have higher discharge efficiency, lower internal resistance due to stacked technology, and better performance in terms of discharge and cycle life. They exhibit excellent high current discharge performance, high power output, high energy density, and good cycle life. They can handle discharge rates up to 150C, 90C for 2 seconds, continuous discharge at 45C, and fast charging at 5C. Lithium iron phosphate batteries can handle high currents of 2C for rapid charging and discharging, with a 1.5C charge taking only 40 minutes to complete using a dedicated charger, and the starting current can reach 2C, a performance not possible with lead-acid batteries. This strong high current discharge performance allows lithium iron phosphate batteries to excel in devices requiring quick start-up and high power output, such as electric vehicles and power tools.

4. Outstanding High Temperature Performance
4.1 The thermal peak of lithium iron phosphate(lifepo4) batteries can reach 350°C - 500°C, with a wide operating temperature range and high temperature resistance. The thermal peak of lithium iron phosphate batteries can reach 350°C - 500°C, compared to around 200°C for lithium manganese and lithium cobalt oxide batteries. They have a wide operating temperature range (-20°C to +75°C) and high temperature resistance. Even at an external temperature of 65°C, the internal temperature can reach 95°C, and after discharging, the temperature can reach 160°C, yet the battery structure remains safe and intact. This outstanding high temperature performance allows lithium iron phosphate batteries to operate normally in high temperature environments and is suitable for various harsh working conditions, such as hot regions and high-temperature industrial settings.

5. Large Capacity
5. The capacity of lithium iron phosphate batteries(LiFePo4) is larger than regular batteries, with an energy density 3-4 times that of lead-acid batteries, 2.5 times that of nickel-cadmium batteries, and 1.8 times that of nickel-metal hydride batteries. Lithium iron phosphate batteries have a large capacity and high energy density. Their energy density is 3-4 times that of lead-acid batteries, 2.5 times that of nickel-cadmium batteries, and 1.8 times that of nickel-metal hydride batteries. The large capacity allows lithium iron phosphate batteries to store more energy in the same volume, providing devices with longer battery life. In energy storage modules, using lithium iron phosphate batteries with a capacity of 50Ah or higher can meet the needs of various large energy storage devices. Different models and sizes of batteries, the higher the capacity, the longer the supply time.

6. No Memory Effect
6. Can be charged at any time, no need to fully discharge before charging, convenient to use. Lithium iron phosphate batteries(LiFePo4) have no memory effect, allowing them to be charged and used without needing to be fully discharged first. This is different from nickel-metal hydride and nickel-cadmium batteries, which have memory effects. Lithium iron phosphate batteries can be used at any state, allowing them to be charged and used conveniently without worrying about the battery's charging status affecting its performance.

7. Lightweight
7. The volume is 2/3 of lead-acid batteries, and the weight is 1/3 of lead-acid batteries, making it easy to carry and install. Lithium iron phosphate batteries(LiFePo4) of the same capacity as lead-acid batteries have a volume that is 2/3 of lead-acid batteries and a weight that is 1/3 of lead-acid batteries. The lightweight feature of lithium iron phosphate batteries gives them a significant advantage in portable devices and electric vehicles. In electric vehicles, the lighter battery weight can reduce the overall vehicle weight, improve energy efficiency, and increase driving range. Additionally, the ease of carrying makes lithium iron phosphate batteries more practical in situations that require portable power sources.

8. Environmentally Friendly and Non-Polluting
8. Does not contain heavy metals or rare metals, non-toxic, non-polluting, complies with European RoHS regulations, and is a green and environmentally friendly battery. All raw materials used in lithium iron phosphate batteries are non-toxic, and the entire production process is clean and non-toxic. These batteries do not contain any heavy metals or rare metals (unlike nickel-metal hydride batteries), are non-toxic (SGS certified), non-polluting, and comply with European RoHS regulations, making them an environmentally friendly battery. Unlike lead-acid batteries, which contain a large amount of lead and can cause secondary pollution if not properly disposed of, lithium iron phosphate materials are non-polluting in both production and use. This environmentally friendly feature meets the requirements of sustainable development in today's society and makes a positive contribution to environmental protection.
