Understand the advantages and disadvantages of lithium iron phosphate battery energy storage technology in one minute. With the rise of the lithium battery energy storage market, some power battery companies have deployed lithium iron phosphate battery pack energy storage business in recent years. Nowadays, lithium iron phosphate batteries have become the mainstream of domestic energy storage technology applications, and lithium battery energy storage will achieve a truly large-scale explosion by 2020 at the latest. With the development and rapid demand of new energy vehicles, lithium iron phosphate batteries have opened up a new world. The editor below will take you to understand the advantages and disadvantages of lithium iron phosphate battery energy storage technology.

　　Lithium iron phosphate battery refers to a lithium-ion battery using lithium iron phosphate as the positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Because its performance is particularly suitable for power applications, the word "power" is added to the name, that is, lithium iron phosphate power battery.

　　1. Advantages of energy storage lithium iron phosphate batteries:

　　1. Lithium iron 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, lithium iron phosphate batteries can be used for 7 to 8 years.

　　2. Safe to use. Lithium iron 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. Lithium iron phosphate batteries are resistant to high temperatures. The thermal peak of lithium iron phosphate batteries can reach 350 to 500 degrees Celsius. The operating temperature range is wide (-20~+75℃) and high temperature (60℃).

　　5. Lithium iron 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.

　　6. Lithium iron phosphate batteries have no memory effect. No matter what state the battery is in, it can be used at any time. There is no need to discharge it completely and then charge it.

　　7. Lithium iron phosphate batteries are green, non-toxic, non-polluting, and comply with European RoHS regulations. They are green and environmentally friendly batteries.

　　2. Disadvantages of energy storage lithium iron 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 lithium iron 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 lithium iron 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.

　　4. The preparation cost of materials and the manufacturing cost of batteries are high, the battery yield is low, and the consistency is poor.

　　5. The tap density of the positive electrode of lithium iron phosphate battery is small, and the density is generally around 0.8 to 1.3.

　　3. Lithium iron 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 lithium iron 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.

　　4. The explosion of grid energy storage increases the demand for lithium iron phosphate batteries

　　At present, the lithium batteries used in energy storage in China are still mainly lithium iron phosphate series. This time, the demand for energy storage in the domestic power grid has exploded, which will directly drive the demand for lithium iron phosphate batteries. The main reasons are: first, the explosion of grid energy storage demand provides a way to reduce overcapacity for lithium iron phosphate batteries that cannot meet the new subsidy policy for new energy vehicles; second, in recent years, power battery companies have improved in technology, cost and other aspects. Development, lithium iron phosphate batteries have cost-effective advantages over lead-acid and lead-carbon batteries.

　　It is estimated that by 2020, the total demand for lithium battery energy storage on the power generation side and the grid side will be 8GWh. Lithium iron phosphate battery UPS has become the mainstream of domestic energy storage, especially grid energy storage applications. Energy storage systems using lithium batteries have become The mainstream choice for power grid groups and operators. Grid energy storage is driving demand for lithium iron phosphate batteries. It is foreseeable that domestic grid energy storage will create a new market breakthrough for lithium iron phosphate batteries.

　　5. Is the best choice for energy storage battery lithium iron phosphate or ternary battery?

　　The battle over the technical routes of lithium iron phosphate and ternary batteries has never stopped. According to foreign media reports, due to the tight production and sales of ternary batteries, more and more energy storage suppliers are beginning to focus on China's lithium iron phosphate batteries. Moreover, some energy storage suppliers said that based on the performance and application market benefits of lithium iron phosphate, the lithium iron phosphate battery energy storage route is currently the right choice.

　　At the same time, the manufacturing capacity of lithium iron phosphate batteries will continue to grow, and the supply period of ternary batteries has been extended to six or even September, further promoting price declines. This will stimulate a significant increase in the application of lithium iron phosphate in user-side energy storage projects.

　　Summary: As a manufacturer of lithium battery UPS and lithium iron phosphate battery packs, we are optimistic about the future market of lithium iron phosphate batteries in the energy storage field. Lithium battery energy storage is mainly used in communication base stations, special aerospace, rail transit, UPS power supply, home energy storage, data centers and other projects. Lithium battery UPS energy storage power supply companies have a large market space.
