  Manufacturing Analytics to Improve Battery Quality and Accelerate Factory Ramp

  The battery industry is racing to develop new manufacturing capacity as the EV and energy storage industries continue to outpace market expectations. Companies across the battery ecosystem have begun building new factories while facing the reality of long yield ramp times, supply chain immaturity, and a shortage of expertise — the typical gigafactory will take several years & billions in investment before reaching profitability.

  In this webinar, we’ll review the industry’s first software solution that enables battery manufacturers to rapidly understand cell quality and the link to upstream production and materials characteristics. This insight, when paired with the ability to control and improve production quality at unprecedented speeds, helps accelerate production ramp and improve overall cell quality.

  This webinar will focus on the following key topics:

  • Challenges around battery manufacturing scale-up and quality across industries
  • Understanding parallels from the semiconductor industry
  • Accelerating production ramp and improving yield, while reducing costs
  • Leveraging AI and ML capabilities to surface quality problems ASAP
  • How a fully integrated analytics solution can speed up battery manufacturing

  Advancements in Physical Vapor Deposition (PVD) for Battery Research

  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 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
