What are the important disadvantages of lithium iron phosphate batteries?

What are the disadvantages of lithium iron phosphate batteries? The so-called lithium iron phosphate batteries refer to lithium ion batteries that use lithium iron phosphate as the positive electrode material. Represented by lithium iron phosphate batteries, a series of reliable words such as environmental protection, safety, and large capacity appear in front of everyone. But we must also understand the shortcomings of lithium iron phosphate batteries and take preventive measures during use. For example: poor low temperature performance, low temperature resistance, low tap density of anode materials, low tap density can be said to be the biggest disadvantage of lithium iron phosphate. According to the after-sales feedback of national car start-up battery sales, it is actually most compatible with some lithium ion The battery, the battery has good low temperature performance, and the domestic use in the northern part of Harbin is completely limited, such as basically not stagnating. In my opinion, the only disadvantage of lithium iron phosphate batteries is size, which means that they have no advantage in small battery applications such as mobile phone batteries. Even if the cost is low, the safety is good, and the stability is good, if the volume is too large, it can only replace lithium cobalt oxide in a small amount. That is: the volume of the lithium iron phosphate battery of the same capacity is larger than that of lithium cobalt oxide and other lithium ion batteries, so there is no advantage in microbatteries. When used in power lithium batteries, lithium iron phosphate batteries are the same as other batteries. They have to face the problem of uneven material composition and poor control of the production process. That is to say, the batteries are usually considered to be consistent. Poor conductivity is the most critical issue. An important problem is that lithium iron phosphate is too late to be used on a large scale. Although this problem can be solved by adding C or other conductive agents. The laboratory reports that it can reach a specific capacity above 160mAh/g. Lithium iron phosphate materials have been added with conductive agents during production, so do not add them when making batteries. In fact, the material should be a composite material such as LiFePO4/C. Consumers in other media have reflected that the lithium iron phosphate battery has a short mileage, basically cannot be recycled after being discarded, has no recycling value, etc., these are some manufacturers using false one-sided reports to earn interest and careless writing. Failure to comply with scientific facts has seriously hindered the development of lithium iron phosphate.
