What are the cost components of energy storage batteries?

The cost composition of energy storage batteries mainly includes the following aspects:

• Battery material cost: Battery materials are the main component of the cost of energy storage batteries, accounting for about 60%-70% of the total cost. Among them, positive electrode materials, negative electrode materials, electrolyte and diaphragm are the main battery materials.

• Battery manufacturing cost: Battery manufacturing cost includes the costs of battery assembly, testing, packaging and other环节, accounting for about 20%-30% of the total cost.

• Other costs: Other costs include the costs of battery management system, inverter, system integration, etc., accounting for about 10%-20% of the total cost.

The factors that affect the cost of energy storage batteries mainly include:

• Battery type: Different types of batteries have different cost structures. For example, the cost of lithium-ion batteries is higher than that of lead-acid batteries.

• Battery capacity: The larger the battery capacity, the higher the cost.

• Battery performance: The better the battery performance, the higher the cost.

• Raw material prices: Fluctuations in raw material prices will affect the cost of batteries.

• Production scale: The larger the production scale, the lower the cost of batteries.
