The advantages of lithium iron phosphate.

1, safety. The safety performance of lithium iron phosphate is currently the best of all materials. Of course, it and other phosphate safety performance is basically the same, with lithium iron phosphate as a battery, absolutely no need to worry about the existence of explosive problems.

2, high stability. Including high-temperature charging capacity stability, good storage performance, etc.. This is the biggest advantage, in all understanding of the material, but also the best.

3, environmental protection. The whole production process is clean and non-toxic. All raw materials are non-toxic. Unlike cobalt which is a toxic substance.

4, cheap. Phosphate using phosphate source and lithium source and iron source for the material, these materials are very cheap, no strategic resources and rare resources.

Disadvantages of lithium iron phosphate.

1, poor electrical conductivity. This problem is its most critical issue. The reason why lithium iron phosphate so late has not been widely used, this is an important issue. However, this problem can now be perfectly solved: is the addition of C or other conductive agents. Laboratory reports can achieve a specific capacity of 160mAh/g or more. Our company produces lithium iron phosphate material with conductive agents already added during the production process, do not add when making the battery. In fact the material should be: LiFepO4/C, such a composite material.

2, the vibration density is low. Generally can only reach 1.3-1.5, low vibranium density can be said to be the biggest drawback of lithium iron phosphate. This shortcoming determines that it has no advantage in small batteries such as cell phone batteries. Even if its low cost, good safety performance, good stability, high cycle times, but if the volume is too large, it can only replace lithium cobaltate in small quantities. This shortcoming will not stand out in the power lithium battery. Therefore, lithium iron phosphate is important to make power lithium batteries.

3, the current research and development is not yet in-depth. The current industrialization of lithium iron phosphate as anode material is not optimistic. Because it is still the last two years of development, so all aspects of the research will continue to be in-depth.
