Analysis of the advantages, application fields, and development prospects of lithium iron phosphate batteries. Lithium iron phosphate batteries are increasingly widely used because lithium-ion battery packs have the benefits of long life, green environmental protection, safety, and small size.

Advantages of lithium iron phosphate batteries:

Lithium-ion batteries have the following significant advantages relative to other types of batteries.

①The working voltage is high. The working voltage of lithium cobalt oxide lithium-ion battery is 3.6V, the operating voltage of lithium manganate lithium-ion battery is 3.7V, the working voltage of lithium iron phosphate battery is 3.2V, and the working voltage of nickel-metal hydride and nickel-cadmium battery is only 1.2V.

②High energy density. The theoretical energy density of cathode materials for lithium-ion batteries can reach more than 200W·h/kg. In practical applications, due to irreversible capacity loss, the energy density is usually lower than this value, but it can also reach 140W·h/kg, which is still NiCd. Three times the battery, 1.5 times the NiMH battery.

③Long cycle life. At present, the number of cycles of lithium-ion batteries can reach more than 1,000 times under the condition of deep discharge; under the condition of low depth of release, the number of processes can reach tens of thousands, and its performance is far superior to other similar batteries.

④ Small self-discharge. The monthly self-discharge rate of lithium-ion batteries is only 5% to 9% of the total capacity, which significantly alleviates the problem of power loss caused by self-discharge when traditional secondary batteries are placed.

⑤ No memory effect. Lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used at any time without having to discharge it thoroughly and then recharge it.

⑥High environmental protection. Regarding the environmental pollution problems caused by the waste of traditional lead-acid batteries, nickel-cadmium batteries, and even nickel-metal hydride batteries, lithium iron phosphate materials do not contain any heavy metals and rare metals, are non-toxic and have no pollution in production and use. The green battery, in a sense.

⑦Fast charging: Li-ion batteries can be charged and discharged quickly at 2C with a large current. The battery can be fully charged within 40 minutes at 1.5C under a special charger, and the starting current can reach 2C, while lead-acid batteries do not have this performance now.

⑧Safety: Safety comes from the stability and reliable safety design of the positive electrode material. The lithium iron phosphate battery has undergone strict safety tests and will not explode even in severe collisions.

⑨High temperature resistance:

· The thermal peak value of a lithium iron phosphate battery can reach 350~500℃.

· The operating temperature range is wide (-20~+75℃).

· 100% capacity can still be released under high temperatures (60℃).

Application areas of lithium iron phosphate batteries:

(1) Application in portable electrical appliances At present, electrical devices that require portable power such as mobile phones, notebook computers, and miniature cameras have become an indispensable part of people's lives. Lithium-ion battery packs are selected as the mainstream of the market in terms of their power sources. According to statistics, the global production of mobile phones is nearly 2.1 billion units per year, and the global annual production of notebook computers is about 150 million units, forming a substantial lithium-ion battery application market. In this field, lithium cobalt oxide and lithium manganate lithium-ion batteries dominate.

(2) Application in the transportation industry With the progress of social civilization, people's awareness of environmental protection and environmental requirements are rising, and environmentally friendly means of transportation have entered people's field of vision. At present, my country's electric light vehicles, mainly electric bicycles, are showing a booming trend. Power lithium iron phosphate batteries have begun to be applied in some high-end models. In the development of electric vehicles, lithium-ion batteries have become the mainstream.

More than half of the electric vehicles developed by many automobile development and production companies use lithium-ion batteries in China, and there is a trend of gradual expansion.

(3) Application in equipment and aerospace industry In equipment, lithium iron phosphate batteries are mainly used as power starting power, wireless communication radio power, power supply for miniature unmanned reconnaissance aircraft, etc. Lithium-ion batteries are also commonly used in video monitors, pilots' life-saving radio power supplies, etc. In the aerospace field, lithium-ion batteries have been used in geostationary orbit satellites and low-orbit communication satellites as power for launch and in-flight corrections and ground operations.

(4) The structural characteristics and particular working principles of other lithium-ion batteries determine their rich raw materials, environmental protection, high specific capacity, good cycle performance, and safety. etc.), petrochemical industry (for example, oil production power load adjustment), power industry (for example, energy storage power supply), etc., all have broad application prospects. It is more critical in today's pursuit of green energy.

The application status of lithium iron phosphate batteries With the rapid development of mobile electronic devices and the continuous increase in energy demand, people's need for lithium-ion battery packs is also increasing. The high capacity, medium voltage, a wide range of sources of lithium-ion batteries, long cycle life, low cost, good performance, and no pollution to the environment determines that it can not only be used in mobile communication tools. Still, it may also become a rapidly growing battery. The power source for the development of electric vehicles.

Analysis of the development prospects of lithium iron phosphate batteries:

As the cathode material of the lithium-ion battery pack, lithium iron phosphate is the safest cathode material of lithium-ion batteries at present. Due to its safety and stability, lithium iron phosphate battery has become an important development direction of lithium-ion power lithium battery. With the global trend of vigorously developing new energy vehicles, the status of my country's lithium-ion battery packs will continue to improve in the future, and sooner or later, it will become a dark horse in the industry.

The annual output of lithium iron phosphate batteries in my country is about 10,000 tons and will continue to rise rapidly in the next few years. Lithium-ion battery packs affect the industrial transformation of new energy fields such as energy storage and are related to developing my country's new energy vehicle market. With the in-depth development of national environmental protection, the development scale of my country's lithium-ion battery industry will become larger and more prominent in the next few years.

With the improvement of lithium-ion battery pack structure development technology, the current energy density of the lithium iron phosphate group has reached the level of ternary NCM523 and is still improving. With policy inclination and technological progress, the future market of lithium iron phosphate batteries can be expected.

Some lithium iron phosphate battery manufacturers also consolidate the existing market while seizing the "new track" through a series of card positions. After years of hard work, GOTION Hi-Tech has some strategic customers in passenger cars and special vehicles, such as SAIC Maxus, Ankai Bus, Dayun Automobile, King Long Bus, etc. In industrial vehicles, GOTION Hi-Tech has established a forklift technology project team. In response to the technical requirements for batteries in this market segment, lithium iron phosphate batteries for forklift trucks have been developed. It is reported that GOTION Hi-Tech forklift power lithium battery has been widely used in tobacco, medicine, food and beverage, automobile and parts, logistics, home appliances, and other manufacturing fields.
