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 position of lithium battery in the battery industry, and second, the position of lithium iron phosphate lithium battery in lithium battery.
At the first level, the lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries are currently used as power batteries. Because of its pollution, Lead-acid batteries are strictly limited to small-scale electric bicycle field currently; Ni-MH battery technology is mature, the purchase and use cost are low, but the self-discharge rate, specific energy, it is used only as a transitional battery; Only lithium-ion battery can be integrated to match the electric vehicle, it has a long cycle life, small self-discharge rate.
At the second level, varieties of lithium iron phosphate batteries are different in the price and security. And security ,a performance, is the fundamental decision of different schools of power lithium battery status factors. From the cathode material, lithium-ion batteries can be divided into lithium cobalt oxide, lithium manganese oxide, ternary materials, lithium iron phosphate four categories. Lithium cobalt oxide battery of the highest degree of industrialization, the most mature technology. Considering the security, lithium cobalt oxide battery mainly used for mobile phones, digital products, small battery areas. In the remaining three lithium batteries, lithium iron phosphate battery for its cost and cycle life advantages of being optimistic about the industry，become China's power lithium battery development.
In China, lithium iron phosphate battery and its industrial development of materials and international basic synchronization, look to the future, its application areas or by electric vehicles, electric bicycles, power tools into the field of wind power, solar power generation equipment, medical equipment, . According to the annual growth rate of 10% to 20%, just the four existing applications (electric vehicles, electric bicycles, electric scooter, power tools), power lithium batteries in the next five years will have 15 billion yuan Market size. If all the use of lithium iron phosphate for driving, then, lithium iron phosphate cathode material will reach 4.5 billion market size.
Although China's lithium iron phosphate station in the international starting line, but our synchronization is "follow the trend", and therefore more developed low-end manufacturing, and lack of high-end innovation, which makes the lower cost of Chinese products, but also make Their own in this area in the industry under the critical point, especially the patent is still greatly troubled.
