The application of lithium iron phosphate battery mainly includes the application of new energy automobile industry, the application of energy storage market, the application of starting power supply, etc. Among them, the largest scale and the most application are the new energy automobile industry.

Batteries used in communication base stations have roughly experienced three stages of development and evolution: open-type lead-acid batteries, acid-proof explosion-proof batteries, and valve-regulated sealed lead-acid batteries. At present, a large number of valve-regulated sealed lead-acid batteries used in base stations have exposed some prominent problems during many years of use: the actual service life is short (3 to 5 years), and the energy volume ratio and energy weight ratio are low. Lower, stricter requirements on ambient temperature (20~30°C); not environmentally friendly.

The emergence of Lifepo4 batteries has solved the above problems of lead-acid batteries. Its long life (more than 2000 times of charge and discharge), good high temperature characteristics, small size, light weight and other advantages are gradually being favored by operators. recognition and favor. The Lifepo4 battery has a wide temperature range and can work stably at -20~60C. In most applications, there is no need to install air conditioners or refrigeration equipment. The Lifepo4 battery is small in size and light in weight. The small-capacity Lifepo4 battery can be wall-mounted. The Lifepo4 battery also relatively reduces the footprint. The Lifepo4 battery does not contain heavy metals or rare metals, is non-toxic, non-polluting, and environmentally friendly.

In 2018, the scale of grid-side energy storage applications exploded, bringing China’s energy storage market into the “GW/GWh” era. Statistics show that in 2018, the cumulative scale of energy storage projects put into operation in my country was 1018.5MW/2912.3MWh, which was 2.6 times the cumulative total scale in 2017. Among them, in 2018, the installed capacity of my country’s new operational storage projects was 2.3GW, and the new operational scale of electrochemical storage was the largest, at 0.6GW, a year-on-year increase of 414%.

In 2019, the installed capacity of newly-commissioned electrochemical storage projects in my country was 636.9MW, a year-on-year increase of 6.15%. According to forecasts, by 2025, the cumulative installed capacity of electrochemical energy storage in the world will exceed 500GW, and the market size will exceed one trillion yuan.

In the 331st batch of “Road Motor Vehicle Manufacturers and Products Announcement” issued by the Ministry of Industry and Information Technology in April 2020, there are 306 types of new energy vehicles (including passenger cars, buses and special vehicles) that carry out telegraphy. Among them, lifepo4 batteries are used. Vehicles accounted for 78%. The country attaches great importance to the safety of power batteries, coupled with the performance optimization of lifepo4 batteries by enterprises, the future development of lifepo4 batteries is limitless.
