    Advanced Techniques For Addressing Issues in Battery Safety and Performance Using Adiabatic Calorimetry

    Adiabatic calorimetry is a widely utilized technique within the field of battery safety research. The method has been adapted from the chemical industry to address a significant range of safety and performance tests on battery components, cells and even modules.

    Although a number of different battery tests may be employed using the ARC, interpretation of results is not always straightforward. Some of the principles which apply to ARC chemical testing do not translate directly to battery testing due to the variable nature of samples.

    This presentation describes both the advantages and limitations of ARC testing on batteries and how the ARC test can be adapted to address different questions in battery research as well as quality control.

    This webinar will focus on the following key topics:

    • The principles of adiabatic calorimetry (ARC)
    • How calorimetry can be used in battery testing
    • What we learn from battery testing by calorimetry
    • Pressure measurement and gas collection during thermal runaway
    • Advanced testing techniques in adiabatic battery calorimetry

    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

    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
