Do you know the main application of lithium iron phosphate batteries ?

Lithium iron phosphate battery also called it:lifepo4 battery, refers to lifepo4 battery using lithium iron phosphate as a positive electrode material.

The advantages of Lithium iron phosphate battery as follow:

1:2high operating voltage,

2:high energy density,

3:long cycle life,

4:good safety performance,

5:low self-discharge rate

6:no memory effect

. . .

So what are the main application fields of lifepo4 batteries?

Do you want to know it? Let is go !

Mainly application areas of lithium iron phosphate batteries as follow

1. New energy vehicle industry is the first part

Because of the advantages in safety , lower and lower cost now,Lithium Iron Phosphate battery are widely used in passenger bus, logistics truck, electric bicycle, etc.

Although, in the current field of new energy vehicles, due to the influence of Chinese subsidy policy on new energy vehicles, ternary batteries once occupied a dominant position with the advantages of energy density, but lifepo4 batteries still occupy a very important place in passenger bus, logistics truck, electric bicycle and other fields.and it has irreplaceable advantage

From Chinese's news data,it is very clearly shows that lifepo4 batteries account for half of the total battery shipments.

With reduction of costs in the further , All of us believe that lifepo4 battery shipments will be more and more

New energy

2.Start power supply is second part

In addition to the characteristics of power lithium batteries, the starter lithium iron phosphate battery also has the ability to output high power instantaneously.

The traditional lead-acid battery is replaced by a power lithium battery with an energy less than one kilowatt hour, and the traditional starter motor and generator are replaced by a BSG motor. ,not only has the function of idling start-stop, but also has the functions of engine shutdown and coasting, coasting and braking energy recovery, acceleration booster and electric cruise.

3. Energy storage market is third part

4Energy storage

LiFePO4 battery has a series of unique advantages as follow:

1: high working voltage,

2:high energy density,

3:long cycle life,

4:low self-discharge rate,

5:no memory effect,

6:green environmental protection, etc.,

And It also supports stepless expansion, suitable for

1:large-scale electric energy storage,

2:in renewable Energy power stations

3:prospects in the fields of safe grid connection of power generation, 4:power grid peak regulation,

5:distributed power stations,

6:UPS power supplies,

7: emergency power supply systems.

As technology develops and the energy storage market grows ,and  lower and lower cost of lifepo4 battery , in recent years, more and more lead acid battery factory have deployed energy storage businesses to open up new application markets for lithium iron phosphate batteries.

why they do this ?

On the one hand, cause of the characteristics of longer life, safer use, larger capacity, and more green environmental protection,lifepo4 battery are very easier to be very important part in energy storage field, more meaningful is extend the value chain and promote the establishment of a new business model. We believe that it will create greater value and bring more employment

On the other hand, the energy storage system supporting the lithium iron phosphate battery has become the mainstream choice in the market.According to Chinese reports, lithium iron phosphate batteries have been tried to be used in electric buses, electric trucks, user-side and grid-side frequency regulation.

(1) Safe grid connection of renewable energy power generation

such as wind power generation and photovoltaic power generation. The inherent randomness, intermittency and volatility of wind power generation determine that its large-scale development will inevitably have a significant impact on the safe operation of the power system. With the rapid development of the wind power industry, especially most of the wind farms in China are "large-scale centralized development and long-distance transmission", the grid-connected power generation of large-scale wind farms poses severe challenges to the operation and control of large power grids.

Photovoltaic power generation is affected by ambient temperature, solar light intensity and weather conditions, and photovoltaic power generation presents the characteristics of random fluctuations. China presents a development trend of "decentralized development, low-voltage on-site access" and "large-scale development, medium and high voltage access", which puts forward higher requirements for power grid peak regulation and safe operation of power systems.

(2) Power grid peak regulation. 

The main means of power grid peak regulation has always been pumped storage power stations. Because the pumped-storage power station needs to build two reservoirs, the upper and lower reservoirs, which are greatly restricted by geographical conditions, it is not easy to construct in the plain area, and the area is large and the maintenance cost is high. The use of lithium iron phosphate battery energy storage system to replace the pumped storage power station, to cope with the peak load of the power grid, not limited by geographical conditions, free site selection, less investment, less land occupation, low maintenance cost, will play an important role in the process of power grid peak regulation .

(3) Distributed power station. 

Due to the defects of the large power grid itself, it is difficult to guarantee the quality, efficiency, safety and reliability requirements of power supply. For important units and enterprises, dual power supplies or even multiple power supplies are often required as backup and protection. The lithium iron phosphate battery energy storage system can reduce or avoid power outages caused by grid failures and various unexpected events, and ensure safe and reliable power supply in hospitals, banks, command and control centers, data processing centers, chemical materials industry, and precision manufacturing industries. Play an important role.

(4) UPS power supply. 

The continuous and rapid development of China's economy has led to the decentralization of UPS power supply users' needs, which has caused more industries and more enterprises to have continuous demand for UPS power supply.

Compared with lead-acid batteries, lithium iron phosphate batteries have the advantages of long cycle life, safety and stability, green environmental protection, and low self-discharge rate. will be widely used.

4. Applications in other fields

Lithium iron phosphate batteries are also widely used in the military field due to their good cycle life, safety, low temperature performance and other advantages.

On October 10, 2018, a battery company in Shandong made a strong appearance at the first Qingdao Military-Civilian Integration Technology Innovation Achievement Exhibition, and exhibited military products including -45℃ military ultra-low temperature batteries.
