  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

  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

  Understand and Prevent Battery Fires and Explosions – and Avoid Costly Failures Like the Samsung Note 7

  Modern batteries (eg Li-Ion) contain hazardous chemicals & they heat up during use: this combination always has the potential to cause fires & explosions. This presentation will focus on improving the understanding of how these incidents occur, what can be done to avoid them & how the risk can be minimized during early stage design.

  The Samsung Note 7 phone & Boeing Dreamliner airplane fires are very costly examples of how even large corporations fail to understand the potential fire risk of batteries.

  The solution lies in knowledge of heat generation rate during normal use & information about safe boundaries such as temperature, discharge rate & overcharge, in realistic situations that represent actual use conditions. Data from commercial batteries of different types 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 & explosions occur
  • How to design safer batteries though 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 generation

  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)
