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, the valve-regulated sealed lead-acid batteries widely used in base stations have exposed some prominent problems during many years of use: the actual service life is short (3 to 5 years): the energy volume ratio and energy weight ratio are relatively low. Low: stricter requirements on ambient temperature (20~30°C): not environmentally friendly.

The emergence of lithium iron phosphate 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 iron-lithium battery has a wide temperature range and can work stably at -20~60C. In most applications, it does not need to install air conditioners or refrigeration equipment; the iron-lithium battery is small in size and light in weight. The small-capacity iron-lithium battery can be wall-mounted The iron-lithium battery also relatively reduces the footprint. The iron-lithium 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 newly commissioned energy storage projects was 2.3GW, and the newly commissioned scale of electrochemical energy storage was the largest, at 0.6GW, a year-on-year increase of 414%.

By 2019, the installed capacity of electrochemical energy storage projects newly put into operation 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 April 2020, the Ministry of Industry and Information Technology issued 331 batches of “Road Motor Vehicle Production Industry and Product Announcements”, a total of 306 new energy vehicles (including passenger cars, buses and special vehicles) were declared, of which lithium iron phosphate batteries were used. Vehicles accounted for 78%. The country attaches great importance to the safety of power batteries, coupled with the performance optimization of lithium iron phosphate batteries by enterprises, the future development of lithium iron phosphate batteries is limitless.
