Despite their unrivaled performance and longevity, Lithium Ion batteries (LIBs) are also increasingly recognized as a safety hazard, especially in large scale energy storage installations. Although high-voltage battery packs and modules can be subject to numerous failure modes which are not present at the single cell scale, safety testing on full-scale battery packs can be prohibitively expensive and highly destructive to perform. In this talk, we demonstrate the importance of combining safety testing at the material, cell, and module scales to enhance the design of cells and packs which may mitigate the potential for catastrophe. Strategies to minimize full-scale testing requirements through a combination of carefully designed single cell tests and physics-based modeling are explored.
This webinar will focus on the following key topics:
• Bridging the gaps between safety concerns at single cell and module levels
• Experimental characterization of li-ion cells under abusive conditions
• Use of reference electrode instrumentation for degradation mode characterization
• Selection of safe battery materials to enhance cell and module level safety
• Role of modeling in ensuring safe battery design

Battery Selection Tutorial Course 1/3: Selecting your Cell and Cell Manufacturer(s)
After designing your product, you need to ensure the battery with which you are operating it will ensure the right performance and lifetime. When deciding this, narrowing down which chemistry (e.g. Li-ion, lithium primary, NiMH, etc.) best fits your product and which form factor are some of the first steps. Choosing a cell design (high-power vs. high-energy, for example) is another step and finally, finding the right cell manufacturer to fabricate your cells and packs. This webinar is the first in a three-part series on designing the right battery for your product. It will cover many of the key differences in chemistries, form factors, and cell designs and other best practices.
This webinar will focus on the following key topics:
• Choosing the right chemistry for your application
• Choosing the right form factor
• Choosing cell designs (e.g. high power vs. high-energy)Presenter

Avoid Battery Explosions and Fires – With Right Data and Better Designs
Modern Li Ion batteries contain hazardous chemicals and heat up during use – this combination always has the potential to cause fires and explosions. This presentation will focus on improving the understanding of how such incidents occur, what can be done to avoid them and how the risk can be minimized during early stage design.
The solution lies in knowledge of the heat generation rate during normal use, and information about safe boundaries such as temperature, discharge rate & overcharge in realistic situations that represent actual conditions of use. Data from commercial batteries of different types, including videos of batteries undergoing thermal runaway, will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:
• Why battery fires and explosions occur
• How to design safer batteries through understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
• Laboratory instruments suitable for testing and data generationPresenter

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 LiMn2O4Presenter

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?Presenter
