Lithium iron phosphate battery industry and international status

Lithium iron phosphate battery industry and international status

With the rapid development of electric vehicle industry, power battery has become an important element. Lithium iron phosphate battery industry status can be divided into two levels of the problem: First, the status of lithium batteries in the battery industry, and second, lithium iron phosphate battery in the lithium battery status.

At the first level, currently used as power batteries with lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries. Lead-acid batteries are strictly restricted use, because of its pollution, is currently limited to the field of small electric bicycles; nickel-metal hydride battery technology is mature, the purchase and use of low cost, but the self-discharge rate, the specific energy is small, only as a transition Battery; only lithium-ion battery can be integrated to match the electric car, it has a long cycle life, the characteristics of small self-discharge.

At the second level, the difference between the various lithium iron phosphate batteries in the price and safety, and security is a performance, is the fundamental decision to power lithium battery status factors. From the cathode material point of view, lithium-ion batteries can be divided into lithium cobalt oxide, lithium manganese oxide, ternary materials, lithium iron phosphate four categories. Lithium cobalt oxide battery the highest degree of industrialization, the most mature technology, but because of security considerations, mainly for mobile phones, digital products and other small areas of the battery. In the remaining three lithium batteries, lithium iron phosphate battery with its cost and the advantages of cycle life by the industry optimistic, as China's power lithium battery development direction.

In China, lithium iron phosphate battery and its industrial development of the basic and international synchronization, its application areas or by electric vehicles, electric bicycles, power tools into wind power, solar power plants, medical equipment, miner's lamp and other fields. If the annual growth rate of 10% to 20%, the existing four applications (electric vehicles, electric bicycles, electric scooters, power tools), power lithium batteries will be in the next 5 years with 15 billion market size The If all the use of lithium iron phosphate for driving, then, lithium iron phosphate cathode material will reach 4.5 billion market size.

China's lithium iron phosphate, although standing on the international starting line, but our synchronization is "follow the sky", and thus low-end manufacturing is more developed, and lack of high-end innovation, which makes the cost of Chinese products is low, but also make Their own in this area under the industrialization of the critical point, especially the patent is still greatly troubled
