It is said that there was no metal on the earth, and the planets that repeatedly hit the earth brought various metals to the earth. Obviously, the planetary impact was too random, and it brought certain problems to the inhabitants of the earth, one of which was lithium. This is the most widely used metal in electrochemical energy storage systems, but the most prosperous region in the current lithium battery industry—China—is trapped in insufficient lithium resources. However, other metals have also entered the battery territory one after another, making electrochemical energy storage colorful.
Lithium iron phosphate and ternary, are they really rivals?
Speaking of lithium iron phosphate batteries and ternary batteries, both are brothers in the field of lithium ion batteries, but in the past two years, lithium iron phosphate batteries and ternary batteries seem to have some trends that you chase after each other. In particular, on November 18, the Ministry of Industry and Information Technology announced the "Regulations for the Li-ion Battery Industry (2021 Version)" (Draft for Comment) and the "Administrative Measures for the Announcement of Li-ion Battery Industry Specifications (2021 Version)" (Draft for Comment) After that, the industry found that there seems to be a certain tendency to inhibit the lithium iron phosphate battery that is making great strides:
The new specification requires that the energy density of the energy type power battery project should be ≥180Wh/kg, and the energy density of the battery pack should be ≥120Wh/kg. Although the energy density of the lithium iron phosphate battery pack exceeds 120, it is quite a lot, but the number of single cells is a bit dangerous, because the energy density of the mainstream lithium iron phosphate battery is still hovering around 160Wh/kg. According to this calculation, many The product cannot meet the new regulations.
But are the new regulations really inhibiting lithium iron phosphate batteries?
Let's start with the positive electrode material. Just like the mellow taste of the bottom of the pot is the soul of the hot pot, the cathode material also assumes the role of the soul of the lithium battery. The cathode material accounts for about 40% of the battery manufacturing cost.
