    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

  • (FREE) KORVUS TECHNOLOGY: Advancements in Physical Vapor Deposition (PVD) for Battery Research

    Wednesday, April 24, 2024 | 10:00 A.M. EDT USA

    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.

  • (FREE) KIM & CHANG: The Future of LFP Batteries From a Patent Landscape Perspective

    Wednesday, May 08, 2024 | 10:00 A.M. EDT USA

    LFP (lithium iron phosphate) has become a key battery technology in the market, competing with NCM. Being both cheaper than NCM batteries, while also offering superior safety characteristics, they have attracted great interest. China’s leadership in LFP has caused many battery players previously focused on NCM to enter the LFP market as well. While LFP batteries also have some disadvantages compared to NCM, such as lower energy density, poor charging performance at low temperatures, and recycling difficulties, many new technologies are being introduced to solve these problems. This talk will review the future of LFP batteries using patent analysis techniques to understand technological development in this area.

    This webinar will focus on the following key topics:

    • Why LFP batteries are attracting attention
    • Why Chinese players dominate the LFP battery market
    • Challenges presented by LFP batteries and potential solutions
    • Can Korean and US companies become leaders in LFP technology?

  • (FREE) TWAICE: De-risk Deployment and Scaling of Battery Energy Storage Systems

    Wednesday, May 29, 2024 | 10:00 A.M. EDT USA

    Battery energy storage systems (BESS) ensure grid stability and align supply with demand by storing surplus energy during periods of abundance and discharging it only when needed.

    But they require a lot of monitoring: individual battery cells vary in quality and age, and these cell imbalances increase stress on the system. This leads to wasted energy and increased downtime. At the same time, regulators are paying attention and developing safety standards that apply to battery storage and the risks involved. In this webinar, you’ll gain a deeper understanding of how analytics can help you identify and mitigate battery performance and safety risks along the entire lifecycle, from design over commissioning & operation to de-commissioning.

    This webinar will focus on the following key topics:

    • De-risk deployment and operators of BESS from design over commissioning & operation to de-commissioning
    • Why monitoring battery systems with advanced analytics is so important
    • How to identify issues with your system early on
    • How to optimize BESS performance
    • Industry best practices and emerging trends

  • (FREE) VOLTAIQ: Accelerating Factory Ramp-up and Quality Through Advanced In-line Electrochemical Techniques

    Wednesday, June 26, 2024 | 10:00 A.M. EDT USA

    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 quality

    A PDF copy of the presentation will be sent to all attendees after the event.
