What are the advantages and disadvantages of 18650 battery 2200mah phosphate batteries? Will 18650 battery 2200mah phosphate battery energy storage technology be an important potential market?

　　1. Advantages of energy storage 18650 battery 2200mah phosphate batteries:

　　1. 18650 battery 2200mah phosphate batteries have a long life, with a cycle life of more than 2,000 times, and 3C cycle life of more than 800 times. Under the same conditions, 18650 battery 2200mah phosphate batteries can be used for 7 to 8 years.

　　2. Safe to use. 18650 battery 2200mah phosphate batteries have undergone strict safety testing and will not explode even in violent collisions.

　　3. Fast charging. Using a special charger, the battery can be fully charged at 1.5C in 40 minutes, and the starting current can reach 2C.

　　4. 18650 battery 2200mah phosphate batteries are resistant to high temperatures. The thermal peak of 18650 battery 2200mah phosphate batteries can reach 350 to 500 degrees Celsius. The operating temperature range is wide (-20~+75℃) and high temperature (60℃).

　　5. 18650 battery 2200mah phosphate batteries have large capacity, and their 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.

　　2. Disadvantages of energy storage 18650 battery 2200mah phosphate batteries:

　　1. Poor consistency. The life of iron phosphate battery pack is significantly lower than that of single battery pack. Compared with other batteries, the lifespan of 18650 battery 2200mah phosphate battery packs has no obvious advantage. There are a large number of battery packs in the second-hand market that have been retired before reaching their expected lifespan.

　　2. Poor low temperature performance. The capacity drops rapidly when it is lower than 0 degrees, and the cycle performance is extremely poor at low temperatures.

　　3. During the sintering process during the preparation of 18650 battery 2200mah phosphate, iron oxide may be reduced to elemental iron in a high-temperature reducing atmosphere. Elemental iron can cause micro-short circuits in batteries and is the most taboo substance in batteries.

　　3. 18650 battery 2200mah phosphate battery energy storage technology will be an important potential market

　　As a cutting-edge technology and strategic emerging industry that affects the future energy landscape, energy storage has entered a critical period of industrial development as policies gradually become clearer. As application fields gradually open up, the market will accelerate expansion. It is expected that the capacity of my country's energy storage market will exceed 600 billion yuan in the next ten years. By 2020, the cumulative installed capacity of my country's energy storage market will exceed 50GW, and the scale of energy storage investment and construction will reach 230 billion yuan.

　　Due to the advantages of 18650 battery 2200mah phosphate batteries such as ultra-long life, safe use, large capacity, and green environmental protection, the transfer to the energy storage field will extend the value chain, help promote new business models, and construct a new industrial chain.
