We are doing science for policy
The Joint Research Centre (JRC) is the European Commission's science and knowledge service which employs scientists to carry out research in order to provide independent scientific advice and support to EU policy.
This 2 day workshop discussed the state-of-the-art of thermal propagation testing.
Leading experts brain-stormed on the potential impact of preventing thermal propagation on the safety testing landscape.
At the end of the workshop rapporteurs presented a summary of each session. Key messages and conclusions were collected and published in a final report.
The European Comission communication "Accelerating Clean Energy Innovation" identified safer and higher-performing batteries as crucial to ensure electro-mobility and reliable energy supply.
Lithium-ion technology can be a solutions for electric transportation and smart grids as well as portable devices.
But the use of lithium-ion batteries can also be dangerous if they are operated outside their contort zone.Exceeding a certain onset temperature, an rapid increase in temperature is called a 'thermal runaway'.
Thermal runaway leads to pressure increase, gas and particulate emission, fire or even explosion. Thermal propagation is a cascade of thermal runaway through an entire battery pack. It can have severe consequences.
The case of a spontaneous single cell otherwise normal operating conditions can be more hazardous as it might happen without warning, without an obvious cause and after a considerable service time (i.e. field failures).
This exploratory research workshop is organised within the Joint Research Centre Exploratory Research Activities.
