Description

Technical Field

[0001] The present invention belongs to the technical field of lithium-ion battery manufacturing, and relates to a large-scale integrated, miniaturized lithium-ion battery manufacturing plant, specifically a CMF micro-plant and a control method thereof. Background Art

[0002] Currently, the production lines at lithium-ion battery manufacturing plants both domestically and internationally are complex, lengthy, and highly homogenized, resulting in enormous waste of manpower, material, financial, and energy resources. For an annual production capacity of 1 GWh of lithium-ion batteries, the fixed asset investment is approximately 500 million RMB, the plant occupies approximately 40,000 square meters, employs approximately 600 people, and the production process consumes approximately 45 million kWh of energy, resulting in high production costs. Consequently, the power battery alone accounts for approximately 45% of the manufacturing cost of a pure electric vehicle.

[0003] Furthermore, the complex and largely homogeneous structure of lithium-ion battery cells and their manufacturing processes make it difficult to implement radical transformations or upgrades to production lines in lithium-ion battery manufacturing plants. Pressured by persistently high production costs, most upgrades involve patchwork or even a reduction in control requirements. However, these technical measures to improve efficiency and reduce labor, material, financial, and energy consumption are limited, or even futile. Furthermore, the resulting reduction in control requirements leads to shorter battery life and greater safety risks. Summary of the Invention
