Lithium battery glue coating process

Why is a coating process important for lithium-ion battery electrodes?

This approach is important not only for lithium-ion battery electrodes, but has applications in many other disciplines, such as coated paper making , catalysts designs and printed electronics . Greater access to measurements, and data, from the process will enable real-time control and optimisation of the coating process.

Why do li-ion batteries have scalloped coating edges?

In the Li-ion battery manufacturing process, uniform coating thickness is essential for ensuring high-quality electrode production. Elevated or scalloped coating edges are often formed because of inadequate coater design. Traditional coater design approaches entail resource-intensive coating experiments or time-consuming simulations.

How does the manufacturing process affect the performance of lithium-ion batteries?

The manufacturing process strongly affects the electrochemical properties and performance of lithium-ion batteries. In particular, the flow of electrode slurry during the coating process is key to the final electrode properties and hence the characteristics of lithium-ion cells, however it is given little consideration.

How can CFD simulations improve coating uniformity in Li-ion battery manufacturing?

CFD simulations of coating uniformity are conducted using 13 design variables. A surrogate model is constructed using CFD simulation data. The optimization reduces defective coating edges by more than 90%. In the Li-ion battery manufacturing process, uniform coating thickness is essential for ensuring high-quality electrode production.

What is lithium-ion battery electrode design & manufacture?

Lithium-ion battery electrode design and manufacture is a multi-faceted process where the link between underlying physical processes and manufacturing outputs is not yet fully understood. This is in part due to the many parameters and variables involved and the lack of complete data sets under different processing conditions.

Why is metrology important for lithium-ion battery electrode design & manufacture?

Extensive metrology must be combined to realise the goal of high quality, low-cost production. Lithium-ion battery electrode design and manufacture is a multi-faceted process where the link between underlying physical processes and manufacturing outputs is not yet fully understood.
