Investigating the safety of non-flammable fluorine-free electrolytes for next-generation batteries

This project aims to investigate the safety of the next generation batteries intended for large-scale energy storage.

Sodium-ion batteries are predicted to be one of the most important technologies for large-scale energy storage in Europe, as all raw materials are available locally at attractive prices.

Since sodium-ion batteries are believed to be built on a large scale, safety for both the environment and humans is very important.

Altris AB in Sweden has developed a competitive sodium-ion battery with an electrolyte consisting of a flame retardant that will be used as a prototype to investigate whether this technology is as safe as the lab tests at Uppsala University indicate. To ensure this, tests on prototypes must be performed.

In addition, FOI and RISE have an interest in evaluating the safety of these technologies at an early stage, as well as the equipment and expertise to conduct a thorough and impartial study of the safety level of this new technology.
