Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as the positive electrode material. With the development of science and technology and new energy vehicles, lithium battery packs have now become the mainstream and their market position is getting higher and higher. With the rapid development of the electric vehicle industry, power batteries have become an important element. The industrial status of lithium iron phosphate batteries can therefore be divided into two levels: one is the status of lithium battery packs in the battery industry, and the other is the status of lithium iron phosphate batteries in lithium batteries. 1. The position of lithium battery packs in the battery industry is at the first level. Currently, lead-acid batteries, nickel-hydrogen batteries and lithium-ion batteries are currently used as power batteries. Lead-acid batteries are strictly restricted. Because of their high pollution, they are currently restricted to the field of small electric bicycles; Ni-MH batteries have mature technology and low purchase and use costs, but they have high self-discharge rate and low specific energy, which can only be used as a transitional one. Batteries: Only lithium-ion batteries can comprehensively match electric vehicles, and they have long cycle life and low self-discharge rate. 2. The status of lithium iron phosphate batteries in lithium batteries On the second level, the difference between various lithium iron phosphate batteries is manifested in price and safety, and safety is a performance that fundamentally determines the power of different genres Factors in the status of lithium batteries. From the perspective of cathode materials, lithium-ion batteries can be divided into four categories: lithium cobalt oxide, lithium manganate, ternary materials, and lithium iron phosphate. Lithium cobalt oxide batteries have the highest degree of industrialization and the most mature technology. However, due to safety considerations, they are mainly used in the field of small batteries such as mobile phones and digital products. Among the remaining three kinds of lithium batteries, lithium iron phosphate battery packs are favored by the industry due to their advantages in cost and cycle life, and become the development direction of China's power lithium batteries. In my country, the industrial development of lithium iron phosphate battery packs and their materials is basically synchronized with the international development. Looking ahead, its application fields may penetrate from the fields of electric vehicles, electric bicycles, and power tools into wind power, solar power generation devices, medical equipment, miner’s lamps, etc. field. Power lithium batteries will have a market scale of 15 billion yuan in the next five years. If all lithium iron phosphate battery packs are used for driving, by then, the lithium iron phosphate cathode material will reach a market size of 4.5 billion yuan. Third, the advantages of lithium batteries 1. The energy is relatively high. It has a high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries; 2. Long service life, the service life can reach more than 6 years, the battery 1C (100 %DOD) charge and discharge, there are records that can be used for 10,000 times; 3. The rated voltage is high (the single working voltage is 3.7V or 3.2V), which is approximately equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries, which is convenient It forms a battery power pack; the lithium battery can be adjusted to 3.0V through a new type of lithium battery voltage regulator technology to suit the use of small appliances; 4. It has high power tolerance, including the phosphoric acid used in electric vehicles. Lithium iron lithium ion battery can reach 15-30C charge and discharge capacity, which is convenient for high-intensity start-up acceleration; 5. Light weight, the weight is about 1/6-1/5 of lead-acid products under the same volume; 6. High and low temperature adaptability It can be used in the environment of -20℃--60℃, and can be used in the environment of -45℃ after process treatment; 7. It is green and environmentally friendly. No matter it is produced, used or scrapped, it does not contain or Produce any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium. In the future, the market position of lithium iron phosphate batteries is promising.
