Advantages of LiFePO4 Battery Energy Storage System
1.LiFePO4 Battery Energy Storage System battery has a long life. The cycle life is more than 2000 times, and the 3C cycle life is more than 800 times. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years.
2. Safe to use. Lithium iron phosphate batteries have undergone rigorous safety tests and will not explode even in severe collisions.
3. Fast charging. Using a special charger, the battery can be fully charged at 1.5C for 40 minutes, and the starting current can reach 2C.
4. The lithium iron phosphate battery is resistant to high temperature. The thermal peak value of lithium iron phosphate battery can reach 350 to 500 degrees Celsius, and the operating temperature range is wide (-20~+75 °C) and high temperature (60 °C).
5. The lithium iron phosphate battery has a large capacity. The energy density is 3 to 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.
6.LiFePO4 Battery Energy Storage System has no memory effect. No matter what state the battery is in, it can be used at any time without having to fully discharge and recharge.
Disadvantages of LiFePO4 Battery Energy Storage System
1. Poor consistency. Iron phosphate battery pack life is significantly lower than that of single cells. Compared with other batteries, LiFePO4 Battery Energy Storage System has no obvious advantage in life. There are a lot of battery packs on the used market that have been obsolete before reaching their expected lifespan.
2. The low temperature performance is not good. When the temperature is lower than 0 degrees, the capacity drops rapidly, and the cycle performance is extremely poor at low temperature.
3. During the sintering process during the preparation of lithium iron phosphate, iron oxide may be reduced to elemental iron in a high-temperature reducing atmosphere. Elemental iron can cause micro-short circuit of the battery and is the most taboo substance in the battery.
4. The preparation cost of the material is higher than the manufacturing cost of the battery of the LiFePO4 Battery Energy Storage System, the battery yield is low, and the consistency is poor.
