Lithium battery module production data analysis

What are the manufacturing data of lithium-ion batteries?

The manufacturing data of lithium-ion batteries comprises the process parameters for each manufacturing step, the detection data collected at various stages of production, and the performance parameters of the battery [25, 26].

Are data mining methods applicable in lithium-ion battery cell production?

In summary, data mining methods were analyzed concerning their applicability in lithium-ion battery cell production. The data collected during several production ramp-ups in a research production facility was processed on the basis of the CRISP-DM-Process. Therefore, data mining goals were defined and suitable data mining methods were selected.

Are lithium-ion batteries able to produce data?

The current research on manufacturing data for lithium-ion batteries is still limited, and there is an urgent need for production chains to utilize data to address existing pain points and issues.

What is the manufacturing process of lithium-ion batteries?

Fig. 1 shows the current mainstream manufacturing process of lithium-ion batteries, including three main parts: electrode manufacturing, cell assembly, and cell finishing .

Will the scale of battery manufacturing data continue to grow?

With the continuous expansion of lithium-ion battery manufacturing capacity, we believe that the scale of battery manufacturing data will continue to grow. Increasingly, more process optimization methods based on battery manufacturing data will be developed and applied to battery production chains. Tianxin Chen: Writing – original draft.

Can data mining reduce battery production cost?

Data mining approaches were applied to a real battery production line. A systematic procedure for data acquisition, processing, and analysis is given. Electrode fabrication and electrolyte filling are identified as key quality drivers. The results can help to decrease battery production cost by reducing scrap rates. 1. Introduction
