Licity® – Slot Die – Heart of the Coating Process

A precise slot die – the heart of the coating process

One of the challenges in the coating process is to generate a homogeneous film. This homogeneity stands and falls with the precision of the coating head. This is why BASF has constructed and built own slot dies, allowing to apply the film to the copper foil in an exceptionally precise manner.

Deep BASF knowhow enabling perfect equipment

"The centerpiece in our coating process is a curious block of solid metal - our slot die", explains Christian Brand, Senior Technical Manager Licity® at BASF.

"This customized slot die is a good example of BASF’s deep and profound knowhow. It has been developed and built by BASF engineers. It enables a very precise coating process, resulting in constant coat weight from the beginning to the end of the production run", explains Fatih Çetinel, Research Engineer Coating and Film Processing.

Electric mobility is among the most promising solutions to today's climate and energy challenges. The key to successful electric vehicles and their mass adoption lies with the technology of lithium-ion batteries. But there is still need for technical improvement - especially, when it comes to charge capacity. By envisioning distinct materials for lithium-ion batteries we at BAS can help to - quite literally - drive this change. Therefore, we developed a new binder series for anodes in lithium-ion batteries.
