Solid-State Batteries – The Key Enabling Technology in Advanced Electric Vehicles
The ‘EV Everywhere Grand Challenge’ has led to extensive research and development of battery technologies with high energy density. To date, state-of-the-art Li-ion batteries (SOA LIBs) based on alkali metal ion intercalation cathodes and anodes have been widely adopted in plug-in hybrid and niche high performance electric vehicles. However, concern with the ultimate limits of SOA LIBs related to their energy density, weight and safety suggests the need for alternatives over the long term. Solid-state batteries (SSBs) have been recognized as an ideal solution that can enable energy densities beyond those of SOA LIBs by utilizing Li metal anode and high voltage cathode, while delivering long cycle life and improved safety. As the key component of SSB, solid-state electrolyte (SSE) replaces the porous separator/ liquid electrolyte to act as a physical barrier and mechanically suppress the formation and penetration of Li dendrites. However, successful development and commercialization of SSBs requires fundamental research related to enhancing the SSE ionic conductivity, stabilizing the electrolyte/ electrode interfaces, cell and pack manufacturing methods, development of battery management systems, and efficient battery pack designs. In this webinar, the practices and principles that have been proposed for dealing with core problems related to SSBs as well as future research avenues that will encourage the adoption of SSBs in real application will be discussed.
This webinar will focus on the following key topics:
• The microstructure role and SSE composition on the Li+ conduction behavior
• Design and development of an effective electrode-electrolyte interface in SSBs
• Mechanistic origins of Li dendrite growth in SSEs and approaches to mitigate the dendrite penetration
• Manufacturing challenges related to mass production of SSBsPresenter

Detailed Approaches for Post-Mortem Analysis of Lithium Ion Batteries
Performance degradation of Lithium Ion Batteries (LIBs) is an important problem not only battery users, but also for battery manufacturers and material suppliers. In this webinar, we will present two topics related to the Post-Mortem analysis of LIBs – one is the performance degradation of SiO anode, and the other is a detailed procedure for the quantitative analysis of electrolyte decomposition and SEI formation on graphite negative electrode.
Toray Research Center can provide detailed and comprehensive data analysis of chemical and morphological changes, using latest instruments, to support material and product performance improvements. Customers can utilize the data set to investigate what may have happened inside the battery, and can correlate the performance degradation with that data analysis.
This webinar will focus on the following key topics:
• Lithium Ion battery
• Post-Mortem analysis
• SiO anode
• Electrolyte degradation and SEI formation
• Morphological observation and Composition analysisPresenter

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
