Accelerating Factory Ramp-up and Quality Through Advanced In-line Electrochemical Techniques
Battery quality issues in production — more specifically, slow identification of issues — severely hamper both new factory ramp-up and in-field device performance and reliability.
By leveraging electrochemical techniques and the fundamental signatures of batteries during the end-of-line process, we can: 1) identify poor-performing cells before they would be otherwise be identified, 2) quickly correlate performance issues to upstream root cause, and 3) identify which electrochemical metrics are best correlated with long-term performance.
In the webinar, we will delve into strategies to leverage end-of-line electrochemical characteristics, encompassing thermodynamics, kinetics, and transport phenomena. The analysis of these fundamental metrics enables the identification of quality issues early to accelerate new factory ramp-up and ensure the performance and reliability of shipped devices.
This webinar will focus on the following key topics:
• The multi-year, multi-billion-dollar battery factory scale-up challenge
• The impact of battery quality variation on devices in the field
• Techniques to understand the fundamental electrochemical signatures of batteries
• Use of these techniques to accelerate factory ramp-up and improve shipped production qualityPresenter

Modeling Mechanical Abuse and Short Circuit of EV Batteries
As electric vehicles (EVs) become more widespread, ensuring lithium-ion battery safety during collisions is increasingly important. Mechanical impacts can cause internal damage, leading to short circuits, thermal runaway, or explosions. Protective enclosures help reduce deformation, but effective design demands accurate failure predictions. This webinar presents a comprehensive approach for modeling mechanical abusive loads on EV batteries, incorporating experiments, material characterization and the Sahraei Failure Criterion—a universal failure model based on microstructural simulations of the electrode-separator assembly. Model validations will be presented across various cell types and loading scenarios in commercial software such as Ansys LS-Dyna and Altair Radioss. Combined with multi-scale simulations, this framework supports the development of safer, more resilient battery systems for EVs.
This webinar will focus on the following key topics:
• Experimental Methods for Material Characterization
• Multiscale Modeling from Components to Cells and Battery Packs
• Short Circuit Prediction with Sahraei Failure
• Applicability to Pouch, Cylindrical and Prismatic CellsPresenter

Advances in Battery Performance and Safety Testing using Calorimetry
This presentation describes two main types of calorimetric techniques that can be used to carry out performance and safety testing on high-energy batteries.
The first half of the presentation introduces isothermal calorimetry; focused on the new IBCx system from Thermal Hazard Technology (THT). Method of operation, hardware overview and examples of data will be presented.
The second half of the presentation covers battery testing methods for the ARC adiabatic calorimeter system. The theoretical background of the test method will be described, and new developments to address blade-type batteries and high ampere-hour cells will be presented.
The presentation also mentions complementary test methods and optional modules that can be integrated with calorimetry to provide more useful analysis. For example; fast-tracking heaters, online gas analysis etc.
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 test requirements
• Discussion of THT lab testing resultsPresenter

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
