(FREE) New Developments in Isothermal Microcalorimetry and ARC® Testing Methods

This presentation describes two main types of calorimetric techniques which can be used to carry out performance and safety testing on batteries. These are isothermal calorimetry and adiabatic calorimetry.

THT’s new Micro Battery Calorimeter is presented along with initial data from a prototype unit. This device is focused on high sensitivity measurement which is required for coin and button cell samples which produce only milliwatts of heat during use. This is an example of an isothermal calorimeter system.

The second half of the presentation covers battery testing methods for the ARC® adiabatic calorimeter system. The theoretical background of the test method is described and recommended practice for various types of testing are discussed.

This webinar will focus on the following key topics:

• Principles of isothermal calorimetry for batteries
• Introduction to the Micro Battery Calorimeter and initial data
• Theoretical background to ARC® testing
• Recommended ARC® testing practices

A PDF copy of the presentation will be sent to all attendees after the event.

All Solid-State Batteries and the Future of Energy Storage

The development of all solid-state batteries (ASSBs) has seen tremendous progress in recent years. However, several barriers still need to be overcome before ASSBs can be commercialized. These obstacles include poor interfacial stability, scalability challenges as well as the difficulty to precisely diagnose problems within the cell. Additionally, efforts to develop sustainable recyclability in lithium ion batteries are still lacking. In this webinar, we discuss SSEs chemistries and its implications on interfacial stability. We also cover the current state-of-the-art characterization techniques and evaluate future ASSB prototyping strategies. Finally, we hope to discuss potential strategies toward a sustainable ASSB recycling model to address the growing lithium ion battery waste problem.

This webinar will focus on the following key topics:

• Overview of solid-state batteries and solid-state electrolyte research
• Importance of interfacial stability – correlate chemical, electrochemical and mechanical-induced reactions
• Challenges for diagnosis / characterization of buried interfaces and lithium dendrites
• Scalable fabrication considerations of commercialized all-solid-state batteries
• Sustainability – Battery recycling concerns of Cost, Efficiency and the Environment

A PDF copy of the presentation will be sent to all attendees after the event.

EIS for Energy Storage Tutorial Course 1/3 – Basics of Electrochemical Impedance Spectroscopy

The theoretical principles of Electrochemical Impedance Spectroscopy (EIS) are given. Details on what is being measured and which information it gives on the studied system are also explained. Some elements will be given on how an EIS measurement is performed from an instrumental point of view. Finally, the requirements that EIS must fulfill are presented.

This webinar will focus on the following key topics:

• What is an EIS measurement?
• Which information do we get from this measurement?
• How is it performed?
• Which requirements should it fulfill?

A PDF copy of the presentation will be sent to all attendees after the event.

EIS for Energy Storage Tutorial Course 2/3 – How to Perform Good and Reliable EIS Measurements

Electrochemical Impedance Spectroscopy (EIS) is a powerful technique, but it might be difficult to know which parameters to set as it really depends on the studied system. We give a few guidelines and tools needed to set the right amplitude, as well as other experimental parameters of interest that can increase the accuracy and the reliability of your measurement.

A discussion will be given about when and whether to choose between potentio-controlled or galvano-controlled EIS.

Finally, we will give recommendations on the conditions that the system under study should fulfill, especially time-variance, with some examples on the effect it has on impedance data and how to correct them.

This webinar will focus on the following key topics:

• How to choose the amplitude of the input signal?
• How to choose between PEIS and GEIS?
• What do I need to check on my system?
