混合

在混合浆料以用于涂覆电极的过程中，必须避免带入气泡。借助真空，可以防止浆料内出现气穴，从而制成均匀的浆料。

真空干燥

在真空下干燥涂覆完毕的电极，可确保将残留水分减至最少。然后，电极通常会转入一个干燥且经调温的舱室内，为下一个生产步骤做好准备。

填充电解质

在填充电池单元的过程中，电解液在真空下通过高精度计量喷枪注入。通过交替抽空和惰性气体吹扫来施加定义的压力曲线，可实现电解质均匀分布。通过这种优化的电解质填充工艺，可以对随后费时且昂贵的润湿工艺步骤产生正面影响。

预化

在电池单元预化过程中，电池首次充电过程会产生强烈的气体逸出。释放出的气体须在真空保护性气体环境下排除。由于此类气体的毒性及可能存在的爆炸风险，必须考虑到客户对真空技术的具体要求。

End-of-Line test

At the end of production a battery cell has to fulfill the manufacturers quality level. Electrical safety, leak tightness, and also the ordered specifications of the end-customer are the main reasons to run end-of-line tests. High cycle times have to be met as the current and future demand in terms of quantity and quality needs 100% testing.

Battery recycling

To enable the shift from conventional to electrical mobility the availability of resources has to be secured. Like for any other product recycling is a cost efficient and sustainable way to reduce the need for constant flow of freshly mined resources. New promising recycling methods can reach up to 91% recycling rate with utilization of processes under vacuum.
