    In batteries involving intercalation of species, by using the impedance response at lower frequencies, it is possible to extract the diffusion coefficient of the intercalated species and monitor its change during discharge and charge.

    Low frequency impedance can also be used to estimate the capacity of a battery. Several strategies are given to perform reliable measurements.

    This webinar will focus on the following key topics:

    • Impedance data at lower frequencies that can be used to extract diffusion parameters of intercalated species

    Battery EIS Tutorial Course 4/4: Factors Affecting EIS Measurements – How to Check and Correct

    When performing an impedance measurement, it is necessary to ensure that the modulation is low enough such that the behavior of the system is linear. It should also be confirmed that the system does not vary in time, and that its stationary state is reached. Several strategies are given to check and correct these phenomena.

    This webinar will focus on the following key topics:

    • For reliable EIS measurements, it should be checked that the response of the system is linear, time-invariant and stationary
    • Several strategies are presented to perform reliable impedance measurements

    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 generation

    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?

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

    Duration – 1 hour

    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

    Recycling of Lithium Ion Batteries From Electric Vehicles

    The recycling of lithium-ion batteries – from EVs and others – will be discussed in this webinar.

    Recently, the pilot plant of project LithoRec II could prove that a newly developed combination of process steps enables the recovery of a mass fraction of 75 % and more on a material recycling basis from lithium-ion batteries. This is supposed to be much better than state of the art. Combining different process steps like discharging, dismantling, shredding, sifting and air-jet separation the project partners were able to achieve their goal: proving that lithium-ion batteries can be recycled better. One interesting process dealing with the electrolyte came in a black box (which was actually white) and this was because of another ongoing patenting process of Lion Engineering. A modified and simplified process works to directly recycle scraps from the production of lithium-ion batteries – in order to protect both: the environment and the stakeholder’s money.

    This webinar will focus on the following key topics:

    • Recycling of Lithium Ion Batteries
    • Recycling Yields and how to regain 75% and more – on a material recycling basis
    • Direct Recycling of LIB-Production Scraps
