The main drawback is that the lithium iron phosphate batteries?

Source: 2020 - 04 - 15 so hits: what is the disadvantage of the lithium iron phosphate batteries? Lithium iron phosphate batteries, refers to the lithium iron phosphate as the anode material of lithium ion battery. Represented by the lithium iron phosphate batteries, appear in front of everyone is environmental protection, safe and reliable, large capacity and a series of words. But the disadvantage of the lithium iron phosphate batteries we must also understand, in use process to take preventive measures. For example: the low temperature performance is poor, not good low temperature resistance, anode material tap density is small, low tap density can be said to be the biggest drawback of lithium iron phosphate, according to the national automobile starting batteries sales customer feedback, actually the most and some lithium battery, battery low temperature performance is very good, in Harbin city in the north of domestic use fully qualified, such as the basic will not stall. I think that is the only drawback of the lithium iron phosphate battery size, which means that they there is no advantage in mobile phone batteries and other small battery application. Even if the cost is low, good security, good stability, but if the volume is too big, only a small number of alternative cobalt acid lithium. Namely: the same volume of lithium iron phosphate battery capacity than cobalt acid lithium and other lithium ion battery, so no advantage in terms of micro batteries. When used for power battery, lithium iron phosphate batteries and other batteries, to face the problem of uneven material composition, production process control is bad, that is to say, the batteries are generally considered to be consistent. Conductivity is the key problem. One of the main problem is that too late to lithium iron phosphate, also there is no large-scale use. Although this problem can be solved by adding C or other conductive material. Laboratory report the specific capacity can reach more than 160 mah/g. Lithium iron phosphate material have been added in the production of conductive agent, don't need to add in making batteries. In fact, the material should be: LiFePO4 / C composite material. Other media consumers reflected the lithium iron phosphate battery short line continuation mileage, discarded after basically cannot be recycled, there is no recycling value, and so on, these are some manufacturers use false one-sided reporting earn interest and careless writing, don't follow the scientific facts, seriously hindered the development of lithium iron phosphate.
