With the vigorous promotion of new energy vehicles and the accelerated popularization of digital electronic products, the lithium battery market has also developed rapidly. Among them, China has become one of the rapidly developing markets for lithium batteries in the world.

　　According to the Qianzhan Industry Research Institute, with the good promotion of the industrial chain, the lithium battery pack market is growing. It is expected that by 2018, the global lithium battery market will reach 231.326 billion yuan.

　　China is one of the major producers of lithium batteries. In 2014, China's lithium battery production reached 5.287 billion units, accounting for 71.2% of the world's total production, ranking first in the world for ten consecutive years. In 2016, my country's annual lithium battery output reached 7.842 billion units, an increase of about three times compared with 2.687 billion units in 2010, with a compound annual growth rate of 19.54%.

　　In 2017, the growth rate of the main application market of lithium battery packs slowed down. The global lithium battery industry scale exceeded RMB 300 billion for the whole year, and the growth rate dropped by 4 percentage points compared with 2016. With the continued promotion of new energy vehicle promotion policies, China's electric vehicle production reached 650,000 units in 2017, and its share of the global electric vehicle market will further increase.

　　The application range of energy storage lithium battery packs is very wide: indoor subsystems such as small computer rooms and weak current rooms, new energy outdoor sites, communication base stations, indoor and outdoor non-air-conditioned sites, unmanned sites such as radio and television, special equipment, petroleum and meteorology.

　　Compared with other lithium battery packs on the market, its features are also very outstanding:

　　1. Under the same volume, the energy density of lithium-ion batteries 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. Therefore, when the battery capacities are equal, lithium-ion batteries The battery will be smaller and lighter than lead-acid, nickel-cadmium, and nickel-metal hydride batteries.

　　2. Long life: The cycle life of lead-acid batteries is about 300 times, and lithium iron phosphate batteries have a longer service life under the same conditions.

　　3. Fast charging: It can charge and discharge quickly with high current of 2C. The battery can be fully charged within 40 minutes at 1.5C with a special charger. The starting current can reach 2C. However, lead-acid batteries currently do not have this performance.

　　4. Safety: Safety comes from the stability of the cathode material and reliable safety design. Lithium iron phosphate completely solves the potential safety hazards of lithium cobalt oxide and lithium manganate. Lithium cobalt oxide and lithium manganate will be damaged under strong collision. It will explode, and lithium iron phosphate has undergone strict safety tests and will not explode even in violent collisions.

　　5. Environmental protection: Lithium iron phosphate material does not contain any heavy metals and rare metals, is non-toxic, has no pollution during production and use, complies with European RoHS regulations, and is a green battery.

　　Overall, the consumer lithium battery market demand maintained a low growth rate of around 3% in 2017. At present, my country's lithium battery material companies are constantly pouring into the international front line, and some material companies have become one of the world's leaders. In the long term, new energy vehicles will become an important industry in my country in the next few years. my country's materials companies are expected to rely on the huge domestic market space to accelerate development and usher in global competition opportunities.
