Physical Vapor Deposition (PVD) in Solid-State Battery Development – A Novel and Cost-Effective Approach
Physical Vapor Deposition (PVD) is a method widely used across industry to deposit a very thin layer of a material on a surface to alter its properties. The technique has been utilized in various areas of battery research, including solid-state batteries.
A key challenge with solid state batteries is the high impedance at the interface between the cathode and the electrolyte. PVD is ideally suited to develop model systems to study and look to improve this problem.
PVD also allows high throughput screening of different materials to accelerate new composition developments with enhanced electrochemical properties.
The HEX series of PVD instruments has some key benefits for battery research. It is a cost-effective solution that is mounted below an existing glovebox, allowing continued use of the glovebox for other purposes and easy access to the vacuum chamber for modification and cleaning. The highly modular nature allows configuration changes without specialist tools, enabling changes in research direction without additional costs.
This webinar will focus on the following key topics:
• PVD techniques are a valuable tool in a wide spectrum of battery research
• Develop model systems to study interfacial phenomena
• High throughput screening of different materials to accelerate new composition developments with enhanced electrochemical properties
• Introduction to the HEX series of PVD instrument and its unique advantages for researchPresenter

Advancements in Physical Vapor Deposition (PVD) for Battery Research
Physical Vapor Deposition (PVD) is used industrially for depositing nanometers-to-microns of a material to produce functional layers/alter surface properties. The technique is paramount in pioneering the development of solid-state/lithium-ion batteries.
Key solid-state challenges are impedance at the cathode-electrolyte interface, volumetric energy density, and dendrites/crack formation during cycling. PVD is ideally suited to manufacturing promising solutions, whilst allowing high-throughput screening of novel material compositions to enhance electrochemical properties.
The HEX is a cost-effective system, mountable beneath an existing glovebox for fully inert development. The unique configuration maximizes glovebox space and enables easy atmosphere-side modification/cleaning. The high modularity facilitates changes without specialist tools, enabling rapid changes in research approach without additional costs. Integration of sputtering/thermal/e-beam/organic evaporation/substrate heating allows extensive material production capabilities.
This webinar will focus on the following key topics:
• PVD techniques used to produce functional layers/alter surface properties
• Development of model systems to study interfacial phenomena
• High throughput screening of novel materials to enhance electrochemical properties
• Introduction to the HEX series of PVD instrument and its key advantages for research, including unique mounting position below the gloveboxPresenter

Challenges in Processing Large-Scale Sulfide-Based All-Solid-State Batteries
Sulfide-based all-solid-state batteries are one of the most promising next generation energy storages. Especially the chlor-Argyrodite material Li6PS5Cl and ceramic sulfide Li7P3S11 are attractive solid electrolyte materials due to their high ionic conductivity. To date a lot of research in terms of material chemistry and cell design is presented in literature. From a production point of view, process parameter studies and process engineering are rarely addressed. To fabricate a thin-film sheet of the separator or composite cathode, conventional wet coating techniques from lithium-ion battery production can be applied, but processing has to be adapted to the properties of the sulfidic materials. Besides stable production atmospheres, the optimized processing is crucial to achieve the maximum possible energy density.
This webinar will focus on the following key topics:
• Changes in Manufacturing Processes from LIB to ASSB
• Requirements for Stable Production Atmospheres
• Choice of Process Parameters (Mixing, Coating, Drying)
• Correlation between cell energy density and optimizing manufacturing processesPresenter
