What is the cost composition of lithium ion batteries?

At present, the cost of lithium battery enterprise is about 1.2 yuan/Wh. In the car power battery cost structure, material costs account for nearly 75%, artificial cost, manufacturing cost (except artificial cost is directly related to battery manufacturing costs, such as workshop, equipment, energy, etc.), and other costs (including capital cost, environmental cost, etc.), is a total of about 25%.

In the lithium battery materials cost, the anode materials about 43% of the cost, the performance of the anode materials and prices directly determine the performance of lithium battery and price.

As for material, 1 KWH power battery needs about 2.3 ~ 2.5 kg anode material. The cost of the anode materials is mainly composed of lithium carbonate and all kinds of corresponding precursor materials;1 KWH of power battery anode materials need about 1.3 ~ 1.4 kg; Electrolyte dosage depends on the use of the anode materials and has bigger difference. In a 1 KWH power battery, there are 1.2 kg (such as the manganese acid lithium battery of Leaf), 1.6 kg (like the lithium manganese of Volt +NCM ternary battery), 2.16 kg (such as Qin PHEV lithium iron phosphate batteries); Different power battery products on the amount of the diaphragm material also have bigger difference. Take representative enterprise for example, within 1 KWH power battery, AESC manganese acid lithium battery takes about 12.5 square meters of the diaphragm, LG chem's "lithium manganese + tenary" battery is nearly 19 square meters, while BYD lithium iron phosphate battery needs 23.5 square meters.
