  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

  Battery Ageing – How Modeling is Used to Predict Battery Life

  Battery modeling and simulation makes it possible to analyze multiple operating conditions and design parameters for batteries and other electrochemical systems and processes. By developing mathematical models you can begin to understand the interaction of electrochemical and chemical processes in the battery and how these processes affect the performance and life of the battery.

  In this presentation, we will take a look at the benefits of modeling and simulation in the design, selection, and operation of a lithium-ion battery. We will especially take a look at how modeling can be used together with testing. These results provide manufacturers and application experts with the data to not only predict battery life but to analyze the implications of design parameters and operating conditions to better understand the limitation of the battery.

  This webinar will focus on the following key topics:

  • Benefits of modeling and simulations in the design, selection, and operation of a lithium-ion battery
  • Implications of design parameters and operating conditions with respect to experimental observations of battery performance, aging, and battery safety
  • How battery modeling can be used together with testing

  Determination of Battery Safety and Performance Parameters Using Adiabatic and Isothermal Calorimetry

  FREE Webinar – Thermal Hazard Technology is a proud sponsor of this event.

  This presentation describes two main types of calorimetry which can be used to carry out safety and performance testing on batteries. Isothermal calorimeters allow for direct heat measurement on cells during use, while adiabatic calorimeters can measure heat released from batteries during thermal runaway.

  Calorimetry can serve as a quantitative scientific method for evaluation of battery safety but it requires appropriate instrumentation. The principles of operation of both types of calorimeters are described along with specific applications within the field of battery testing.

  A combination of both technics allows for detailed thermal characterization of lithium-ion and other rechargeable cells, and differences due to chemistry, cell design, cell age, state of charge and cell size can be evaluated.

  This webinar will focus on the following key topics:

  • The principles of adiabatic and isothermal calorimetry
  • How calorimetry can be used in battery testing
  • Parameters established by adiabatic safety testing
  • Parameters established by isothermal performance testing
  • Pressure measurement and gas collection

  Electrochemical Impedance Spectroscopy and Its Application to Battery Analysis

  Electrochemical Impedance Spectroscopy (EIS) is a well-established experimental technique that has applications in coatings, corrosion, sensors, electrochemical double layer capacitors, batteries among others. The power of EIS partly comes from its ability to access a very wide range of frequencies (typically from MHz to μHz). For batteries, parameters such as the internal resistance, electrode surface capacitance and leakage are accessible at different frequencies across the spectrum. This allows EIS to gather all the relevant information with a single measurement. In this webinar, we will briefly introduce EIS and cover its application to batteries. We will talk about how to analyze typical data and how to gather the relevant information. We will further talk about available instrumentation and their limitations.

  This webinar will focus on the following key topics:

  • What is impedance spectroscopy?
  • What can impedance spectroscopy do for Battery analysis?
  • How can capacitance, internal resistance and leakage be determined using EIS?
  • What are the instrumental requirements and limits?
