  Advancing Mining Processes to Make Better Materials for Use in Lithium Ion Batteries

  American Manganese Inc has developed a low-cost, environmentally friendly hydrometallurgical process to recover manganese (Mn) from lower grade resources. American Manganese has applied for a patent for their hydrometallurgical process that produces electrolytic manganese metal with low energy and water consumption. American Manganese commissioned R&D contractor, Kemetco Research Inc to determine uses of Artillery Peak manganese resource material to generate high value alternative products. Chemical manganese dioxide (CMD) and lithiated manganese oxide (LixMn2O4) for use in rechargeable batteries were the areas researched.

  The research was successful in producing CMD from Artillery Peak resource material with low cation impurities and avoiding processing steps that are known to introduce metallic impurities in the final product. Cation impurities cause capacity fade, whereas metallic impurities are known to cause catastrophic failures (such as fire and explosions) in lithium ion batteries. Working rechargeable lithium ion coin cell battery prototypes were produced from the CMD material.

  This webinar will focus on the following key topics:

  • Catastrophic failure of Li Ion batteries caused by metallic impurities that may be introduced from the mining of raw materials
  • Conventional mining process to recover MnO2 used to make LiMn2O4
  • Research on a new mining process that avoids steps known to introduce metallic impurities to recover MnO2 used to make LiMn2O4

  Maximizing Battery Performance and Reliability for Electric Vehicles and Energy Storage

  FREE Webinar – Voltaiq is a proud sponsor of this event.

  As automakers and utilities transition away from non-renewable energy sources, batteries have become essential for efficient energy storage and delivery. Companies are working intensely to deliver higher capacity and more robust batteries to power their products, but ad hoc development processes cannot keep pace with the volume of battery data being generated. In addition, understaffed battery  development teams are unable to leverage their data to accelerate development or improve production and manufacturing.

  In this webinar, we will outline the challenges that the battery industry is facing and how big data analytics can virtually eliminate manual data management and provide powerful capabilities that deliver rapid insights into a battery’s design that dramatically accelerate the development process and results in products with greater performance and reliability.

  This webinar will focus on the following key topics:

  • Recognizing the challenges and bottlenecks in battery development today
  • Automating the battery data collection, data cleaning, and data management process
  • Identifying design issues earlier with predictive analytics
  • Leveraging metadata to understand the impact of materials, processes and test conditions

  Beyond Electrochemical Analysis – 2D to 4D Correlation of Microstructure and Chemistry in Li-ion Batteries

  Single imaging instruments as well as correlative microscopy workflows have demonstrated some unique abilities to support LIB research beyond electrochemical analysis methods. Light microscopy delivers insights about ablation effects & phase orientations in the active material, while scanning electron microscopy (SEM) reveals information about aging effects, nanometer cracks & the composition of the active material. Combining SEM with in-situ Raman spectroscopy extends the traditional SEM capabilities to organic and inorganic material identification. X-ray microscopy, furthermore, delivers 3D non-destructive imaging of full battery packs and localized high-resolution information, thus allowing the identification of regions of interest within the battery material volume. This presentation will demonstrate the application of these techniques to Li-ion battery research, including examples on anode, cathode, binder, and separator materials.

  This webinar will focus on the following key topics:

  • Introduction to available microscopic investigation techniques
  for Li-ion battery research:
  – Light Microscopy
  – Scanning Electron Microscopy
  – X-ray Microscopy
  – Raman Spectroscopy
  • Review of recent battery imaging studies in published literature
  • Case studies on using correlative microscopy to characterize battery performance & failure mechanisms

  Stability of Li7La3Zr2O12 Garnet Solid-State Electrolyte Against Metallic Lithium

  Energy storage demands will require safer, cheaper and higher performance electrochemical energy storage. While the primary strategy for improving performance has focused on state-of-the-art Li-ion batteries, this work seeks to develop solid-state batteries employing metallic Li anode. Recently, the ceramic electrolyte, Li7La3Zr2O12 (LLZO) cubic garnet, has shown promise owing to its unique combination of properties such as high Li-ion conductivity and electrochemical stability. Generally, LLZO is synthesized through powder processing and sintering at high temperature to produce dense membrane. Processing of the ceramic materials produces internal and surface flaws which will inhibit lithium transport creating localized current density and control the stability against Li dendrite propagation. This presentation will discuss new improvement in methodology to evaluate the integrity of LLZO membrane.

  This webinar will focus on the following key topics:

  • Methodology to evaluate the integrity of LLZO by identifying the microstructural flaws and their impact on mechanical properties
  • DC cycling, EIS, XPS will be shown to determine the reactions that govern the maximum current density
  • Correlate the electrochemical stability and critical current density with defects in polycrystalline solid state LLZO electrolyte
