Introduction to the five advantages of lithium iron phosphate batteries

Compared with the more common lithium cobalt oxide and lithium manganate batteries currently on the market, lithium iron phosphate batteries have at least the following five advantages: higher safety, longer service life, and no heavy metals and rare metals. (The cost of raw materials is low), supports fast charging, and has a wide operating temperature range. 2. Higher safety. The iron phosphate power completely solves the safety hazards of lithium cobalt oxide and lithium manganate. The binding force of the phosphate chemical bond is stronger than that of the traditional transition metal oxide structure chemical bond, so the structure is more stable, and It is not easy to release oxygen. 3. Longer service life At present, most of the lithium-ion batteries used in mobile power sources on the market have a cycle life of about 500-800 times, while lithium iron phosphate batteries have a service life of at least 2000 times. And its capacity can be maintained above 80%. Therefore, if the internal storage unit of the mobile power supply is a product of lithium iron phosphate, it has an absolute advantage of normal service life. The positive electrode material of lithium iron phosphate battery does not contain precious metals and rare metals, so it is more environmentally friendly and can effectively reduce environmental pollution. In addition, a wide range of material sources also makes its material cost lower and has a better price advantage. 4. Fast charging speed. Lithium iron phosphate also has a greater advantage in charging speed. The feature of supporting fast charging allows it to support at least 2C charging speed (C is the charging parameter, such as a battery with a capacity of 1000mAh, 2C current That is 1000mA×2u003d2000mA). It can greatly shorten the charging time. At present, most mobile power sources on the market use the standard 5V charging voltage, and the charging current is usually 0.2C. 5. Larger operating temperature range Compared with other lithium-ion batteries, lithium iron phosphate batteries have a larger operating temperature range, which can work normally from -20C to +75C. Some iron phosphates with high temperature resistance characteristics Lithium-ion batteries can also work normally in the range of 350C to 500C, which has more advantages than the 200C limit of lithium manganese oxide and lithium cobalt oxide.
