Cutting lithium ion battery

How are lithium-ion batteries made?

The industrial production of lithium-ion batteries usually involves 50+ individual processes. These processes can be split into three stages: electrode manufacturing, cell fabrication, formation and integration. Equipment plays a critical role in determining the performance and cost of lithium-ion batteries.

Laser processes for cutting, annealing, structuring, and printing of battery materials have a great potential in order to minimize the fabrication costs and to increase the electrochemical performance and operational lifetime of lithium-ion cells.

Can laser cutting of electrode materials be used for lithium ion cells?

Summary and Future Work The presented work discussed experiments of laser cutting of electrode materials for the production of lithium ion cells. The experiments focused on the cutting edge quality. The cutting edge quality was investigated by evaluating the geometrical parameters in macroscopic cross sections.

Do production processes affect the quality of lithium ion battery cells?

Different research groups are investigating the influence of several production processes on the quality of the produced lithium ion battery cell. One investigated process is the cutting of the cell electrodes.

Can remote laser cutting be used in a lithium ion battery production line?

However, remote laser cutting is not state of the art in a conventional lithium ion battery production line, even though it is a highly reproducible, wear-free and flexible cutting method.

Is laser cutting a core process in large-format battery production?

In this work, the laser cutting of electrodes as one of the core processes in large-format battery production is addressed. A comprehensive literature review on the boundary conditions and the relevant quality characteristics of the separation process is presented.
