ELGIN, IL — Mobility-related changes mean that the need for high-performance batteries for e- vehicles — and thus demand for Plasmatreat’s area of expertise — is rapidly increasing. Plasma pretreatment is the key technol- ogy for microfine cleaning, sur- face activation and nanocoating of practically all materials. When plasma, with its high
energy level, comes into contact with materials, the surface prop- erties of those materials change. This can be used to great effect in the various stages of battery production and can be achieved with Plasmatreat’s systems and equipment for activating, clean- ing and coating surfaces. For example, optimization of electrical insulation can be
R&S Validates MediaTek 5G RedCap Test
Platform COLUMBIA, MD — Rohde & Schwarz and MediaTek have partnered to successfully verify MediaTek’s 5G RedCap (reduced capability) test platform, as de- fined in 3GPP Release 17. Red- Cap will enable a new range of 5G standalone devices such as industrial sensors for 5G smart factories, logistics, edge-AI and always connected wearables. Rohde & Schwarz has tailored the R&S CMX500 OBT wireless communications tester to sup- port RedCap and other Release 17 features. Rohde & Schwarz has opti-
mized the R&S CMX500 OBT for IoT testing. R&S CMX500 OBT enhancements let MediaTek ver- ify the various RedCap aspects defined in 3GPP 5G Rel.17 for network access restrictions, bandwidth parts (BWP), band- width part switching, power sav- ing and other RedCap-specific protocol signaling procedures. The R&S CMX500 wireless communication tester has a one- box tester configuration for best- in-class, futureproof testing of 5G NR. The R&S CMX500 sup- ports all relevant 5G frequencies up to 8 GHz via the intuitive and flexible web-based user interface R&S CMsquares. The signaling test solution is suitable for all 5G mobile devices and chipsets. The R&S CMX500 supports
all possible 5G NR network de- ployments and frequency ranges; including the FR1, FR2 and LTE
bands in a single instrument. Contact: Rohde & Schwarz

achieved via plasma cleaning prior to coating or the covering of individual cells with PET film. In cell-to-cell bonding (adhesion of individual cells to the battery module) plasma treatment acti- vates the cell surfaces after the application of the coating or the film covering, thereby improving adhesion and increasing thermal conductivity. The adhesiveness of structural bonding in a battery module, e.g. of the side walls, can be increased through plasma treatment of the components. Plasma technology is also used
for cleaning battery terminals before contact (wire bonding) and coating the overall housing of the battery module for active corrosion protection or treatment
