Is there a lot of room for the energy density of lithium iron phosphate batteries?

At present, from the perspective of positive and negative electrodes, the lithium iron phosphate cathode material system used by domestic and foreign manufacturers is the most important. The power lithium-ion battery market in Europe and the United States basically uses more lithium iron phosphate, while Japan and South Korea need to adopt three Meta-system, it can be said that the current power lithium-ion battery of the lithium iron phosphate system is still the most mature and safest lithium-ion power lithium-ion battery. Although, lithium iron phosphate is almost the lowest energy density in the phosphate system. But if the positive electrode system can increase the core material content of the entire positive electrode to more than 30%, then its actual energy density will be greatly improved. For example, the lithium-rich system, which is made into a battery, can achieve a single cell energy density of more than 300Wh/kg, even exceeding the energy density currently achieved by the ternary system. While increasing the specific energy of the positive electrode material, increasing the specific energy of the negative electrode material is also a major technological breakthrough direction. In the current lithium iron phosphate battery, if 370 graphite is still used as the negative electrode material, it is really difficult to achieve high specific energy. Therefore, the industry attaches great importance to silicon-based materials with high specific energy, including selenium-based materials. Therefore, under the current system, if the lithium iron phosphate battery can be fully completed, the energy density can reach about 120Wh/kg, which has no problem with the application of electric vehicles.
