Six performance characteristics of the lithium iron phosphate batteries

Source: 2020 - 04 - 14 18:54 hits: the performance characteristics of the lithium iron phosphate battery of lithium iron phosphate battery to lithium battery network characteristics of the pool has a special page: the nominal voltage 3. 2 v, charging voltage terminal 3. 6 v, discharge voltage terminal 2. ov。 At present, lithium iron phosphate battery is still in the burgeoning industry. Different manufacturers use of anode, cathode and electrolyte material quality and the process is different, even the same type battery performance is different also. The main advantage of the lithium iron phosphate batteries are: 1) Good security. Even if the battery internal or external damage, also won't soften or explosion. This is conducive to eliminate the collision of road traffic accidents and other safety hidden trouble, avoid the loss of expanding. 2) Low cost. Because of the lithium iron phosphate, iron, lithium phosphate resources are very rich, raw materials readily available, so with the development of manufacturing technology, such as technology, prices are expected to fall sharply. 3) Long cycle life. After a 500 - cycle, discharge capacity is greater than 95%, maximum cycle life of up to 2000 times. 4) Good charge and discharge characteristics. Large currents can be fast charging and discharging, in the special charger, 1. 5 degrees Celsius for 40 minutes can make batteries, short-term discharge current as high as 210 c, instant ( 10) 20 c, pulse discharge in the discharge of 0 v will not damage, no memory effect, in a certain loss of storage conditions, can also maintain a good battery performance. 5) Good environment protection. Lithium iron phosphate batteries of all raw materials are non-toxic, so the whole production process is non-toxic, namely the production and use are non-pollution to the environment. 6) Good temperature characteristic. Suitable for use at room temperature, high temperature resistant, even if the overflow of up to 160 ℃, the battery structure is safe and complete. Lithium iron phosphate batteries are the main disadvantages of vibration density is low, can only reach 1. 3 to 1. 5g/cm3。 Low vibration density makes specific surface area, larger volume. Therefore, mainly used in the manufacture of lithium iron phosphate power battery. Because the battery is still in the development and use in the early stages of some special processing technology such as pulping, pulp, rolling industrialization is needed. Mature technology will greatly improve the efficiency of the mass production cost.
