What is the energy density of a power lithium-ion battery?

Image
At present, China's vehicle power lithium battery technology route chooses the same lithium iron phosphate route as the United States. There is no doubt that lithium iron phosphate batteries have many advantages: high stability and relatively cheap price, but their energy density (higher energy density can better solve the problem of battery life) has very limited room for improvement. It is understood that the energy density of lithium iron phosphate batteries can reach 157Wh/kg, but the energy density of single cells is reduced to 100Wh/kg. At present, the capacity density of lithium iron phosphate batteries is generally around 150Wh/kg. Even better, it's still around 160Wh/kg. Compared with the energy density of the ternary battery of 200Wh/kg, there is a big gap. The 32131 high-energy-density cylindrical lithium iron phosphate battery to be produced has a single energy density of 180Wh/kg, and the cruising range of passenger cars using this battery can reach...

The price of lithium carbonate is 380,000 yuan / ton, an increase of nearly 8 times a year

Prices of some of the raw materials used to make lithium-ion batteries for electric vehicles continue to soar, the latest data shows. Lithium carbonate rose by 14,000 yuan/ton today, and the latest quotation was 380,000 yuan/ton; lithium hydroxide rose by 10,500 yuan to 11,500 yuan per ton, and lithium iron phosphate, the cathode material, rose by 7,500 yuan per ton. On February 7, the price of battery-grade lithium hydroxide was 310,000 yuan/ton, and it will exceed 320,000 yuan/ton after rising today. Today's lithium iron phosphate price is 140,000 yuan / ton. The price has continued to rise steadily recently, and the supply is seriously insufficient. In the past two years, the price of raw materials for lithium batteries has really gone crazy. Previous data showed that the price of lithium carbonate raw materials was around 50,000 yuan/ton in January last year, and exceeded 300,000 yuan/ton for the first time in January this year. Soared to 380,000 yuan / ton. I...
