Modern battery technology offers a number of advantages over earlier models, including increased specific energy and energy density (more energy stored per unit of volume or weight), increased lifetime, and improved safety .
Venjakob developed a special workpiece carrier for the desired six-sided coating in a single pass, which reliably protects the sensitive areas and electrical poles of the battery cell from overspray during the entire coating process. In the spray booth, the cells are coated by permanently installed spray guns.
But, in a solid state battery, the ions on the surface of the silicon are constricted and undergo the dynamic process of lithiation to form lithium metal plating around the core of silicon. “In our design, lithium metal gets wrapped around the silicon particle, like a hard chocolate shell around a hazelnut core in a chocolate truffle,” said Li.
In the conventional way, battery cells, especially prismatic cells, are protected by a film. This process is costly and time-consuming and contains several sources of error. For example, condensation can accumulate under the protective film or the formation of unevenness in the bonding process can impair functionality.
In the second step, the prismatic battery cells at Venjakob are coated with a special 100 % UV protective coating in a fully automated, contact-free process. It is essential to protect the so-called terminals from overspray during the coating process.
