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

Manufacturing Analytics to Improve Battery Quality and Accelerate Factory Ramp
The battery industry is racing to develop new manufacturing capacity as the EV and energy storage industries continue to outpace market expectations. Companies across the battery ecosystem have begun building new factories while facing the reality of long yield ramp times, supply chain immaturity, and a shortage of expertise — the typical gigafactory will take several years & billions in investment before reaching profitability.
In this webinar, we’ll review the industry’s first software solution that enables battery manufacturers to rapidly understand cell quality and the link to upstream production and materials characteristics. This insight, when paired with the ability to control and improve production quality at unprecedented speeds, helps accelerate production ramp and improve overall cell quality.
This webinar will focus on the following key topics:
• Challenges around battery manufacturing scale-up and quality across industries
• Understanding parallels from the semiconductor industry
• Accelerating production ramp and improving yield, while reducing costs
• Leveraging AI and ML capabilities to surface quality problems ASAP
• How a fully integrated analytics solution can speed up battery manufacturingPresenter

Failure Analysis of Next Generation Si Based Anodes
Silicon (Si) is an attractive alternative to graphite due to its high theoretical capacity of 3500 mAh-g-1 and its high abundance on earth. Unfortunately, Si is plagued by significant volume expansion during charge/discharge, upwards of 300%. As a result, researchers and companies have focused their attention on mitigating the disadvantages of Si. With various methods the aim is to create a Si based anode that has a stability comparable or better then graphite. With increasing interest, it is important to discuss and determine abuse testing and failure analysis techniques that can effectively determine the durability of these new anodes.
This webinar will focus on the following key topics:
• Why is it important to look at alternative anodes to graphite?
• The advantages and disadvantages of Si based anodes
• Creation of new anodes to alleviate the disadvantages of Si
• Customized abuse testing and failure analysis of Si based anode cellsPresenter

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
