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

Solving Dielectric and Thermal Challenges in EV Batteries with Adhesive Tapes
The use of electric vehicles in North America is on the rise, and the need for comprehensive safety measures for their batteries is essential. This talk will explore dielectric and thermal protection with pressure sensitive adhesive tapes as a key component of electric vehicle battery safety. We will discuss the benefits of such tapes, their basic composition, and how they can reduce the risk of failure due to electrical or thermal overloads. In addition, we will investigate how these tapes can be combined with other materials like aerogel, thermal ceramics, mica, foam, and more. Finally, we will consider some of the potential challenges and solutions associated with implementing pressure sensitive adhesive tapes in electric vehicle battery safety.
This webinar will focus on the following key topics:
• Understanding the challenges of dielectric and thermal protection in E-mobility
• Learning how to address those challenges with different materials
• Flame retardant mounting and encapsulation tapes
• Emergency Thermal Propagation Venting tape solution
• Puncture, abrasion, and high voltage resistant tapes for robust electrical insulationPresenters

Enabling High-Rate Lithium Metal Anodes by Tailored Structures and Interfaces
Oxide-based solid-state Li-batteries (SSLiBs) have the potential to be a transformational and intrinsically safe energy storage solution, due to their non-flammable ceramic electrolyte that enables the use of high-capacity Li metal anodes and high voltage cathodes for higher energy density over a much wider operating temperature range. However, their progress has been limited due to electrode/electrolyte interfacial issues. In particular, for Li-metal anodes concerns over dendrite formation/propagation and the requirement for elevated temperature and high stack pressure are still prevalent. To eliminate these concerns, a rational design of tailored structures and interfaces in Li-metal anodes will be presented. In addition, progress toward full cells using these tailored structures and interfaces will be presented.
This webinar will focus on the following key topics:
• Li-metal wetting of oxide electrolyte interface
• Effect of oxide surface defects on Li dendrite formation
• Effect of 3D structure on localized current density
• Avoiding stack pressure to maintain uniform Li/oxide contactPresenter
