  • (FREE) TWAICE: A New Generation of Aging Models for Lithium-ion Batteries

    Wednesday, March 27, 2024 | 10:00 A.M. EDT USA

    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 outlook

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

  • (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.

    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 glovebox

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

  • (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?

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