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

Latest Advancements in Calorimetry for Battery Performance and Safety
This presentation covers two essential calorimetric techniques for performance and safety testing of high-energy batteries. Starting with THT’s latest innovation, the IBCx, an isothermal battery calorimeter that delivers precise thermal control, providing crucial insights into the effects of C-rates on heat output, efficiency, and temperature during charge and discharge cycles. The IBCx also allows for quick measurement of heat capacity within the same system.
As the battery market shifts toward larger, higher-capacity cells in the form of long, thin blade cells, THT has developed its largest adiabatic ARC. The ARC is designed to evaluate the thermal stability and safety limits of these batteries under extreme conditions such as elevated temperatures, overcharge, short circuit and nail penetration. The presentation also highlights complementary test methods including online gas analysis.
This webinar will focus on the following key topics:
• Principles of isothermal and adiabatic calorimetry testing for high-energy batteries
• Advantages and limitations of these two methods
• New product developments from THT to address market demand for testing of large format, high-capacity cells
• Integration of on-line gas analysis with ARC testingPresenter

A New Generation of Aging Models for Lithium-ion Batteries
Over the past years, scientists have invested a lot of time and resources to optimize semi-empirical, physico-chemical, and data-driven simulation models. All of them show different challenges and limitations. To overcome this dead end, scientists and engineers combine physicochemical-mechanical degradation effects and integrate them into (semi)-empirical as well as data-driven approaches. We call this combination physics-motivated semi-empirical aging models.
This webinar will focus on the following key topics:
• How capacity aging model is optimized using bootstrap resampling
• The new generation of physics-motivated semi-empirical aging models: OCV aging, degradation modes, understanding the accuracy of models, simulation of swelling force
• The new TWAICE simulation model portfolio: base model, customized base model, premium model
• Vision and outlookPresenters

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
