  A New Generation of Aging Models for Lithium-ion Batteries

  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

  Failure Analysis of Next Generation Si Based Anodes

  Silicon (Si) is an attractive alternative to graphite due to its high theoretical capacity of 3500 mAh-g-1 and its high abundance on earth. Unfortunately, Si is plagued by significant volume expansion during charge/discharge, upwards of 300%. As a result, researchers and companies have focused their attention on mitigating the disadvantages of Si. With various methods the aim is to create a Si based anode that has a stability comparable or better then graphite. With increasing interest, it is important to discuss and determine abuse testing and failure analysis techniques that can effectively determine the durability of these new anodes.

  This webinar will focus on the following key topics:

  • Why is it important to look at alternative anodes to graphite?
  • The advantages and disadvantages of Si based anodes
  • Creation of new anodes to alleviate the disadvantages of Si
  • Customized abuse testing and failure analysis of Si based anode cells

  Advanced Thermal Foams for Battery Pack Protection

  The risk of thermal runaway in lithium-ion battery systems remains a critical challenge, necessitating advanced thermal management solutions for improved safety and reliability. This study introduces a high-temperature resistant foam engineered to enhance battery pack protection through robust insulation and mechanical adaptability for pouch and prismatic cell form factors. The material demonstrates superior thermal resistance across both LFP and NMC chemistries, effectively mitigating heat propagation and maintaining structural integrity under extreme conditions. Designed for versatility, the foam can be integrated across battery components —cell-to-cell pads, vent covers, and gaskets. It provides thermal barrier protection, high-temperature sealing, and targeted venting at the cell, module, and pack levels.

  This webinar will focus on the following key topics:

  • Multi-functional material that provides mechanical support and thermal protection
  • Mechanical properties’ tuning for pouch or prismatic form factors
  • Robust thermal insulation properties for LFP or NMC
  • Performance highlights from: i.) NMC811 testing, ii.) high temperature furnace & hot microscope study and iii.) preliminary benchmarking
  • Application case studies based on thermal protection at cell, module and pack level

  Battery Management System Impacts on Energy Storage

  Battery management systems impact the utility, effectiveness, and life of an energy storage system. Passive balancing is less expensive than active balancing, but weaker cells or modules may need to be replaced near the end of the ESS’s lifespan. Active balancing transfers energy from stronger to weaker cells, but at a higher system cost and design complexity.

  System down time is associated with both approaches and carries such a high opportunity cost that innovations in this area may be of greater importance than the type of balancing being employed.

  Join Nuvation Energy CEO Michael Worry for an exploration of the current state of the art in battery cell balancing, and how BMS innovations will impact the future of stationary energy storage.

  This webinar will focus on the following key topics:

  • A stationary ESS orientation on battery management
  • Understanding balancing-related down time
  • Comparing active and passive balancing
  • Innovations in battery management
