Testing the Flammability of Battery Electrolytes with TAG X00
Different solvents or mixtures thereof are used for the production of Li-Ion battery electrolytes. The flash point of the respective solvent is essential for quality control and thermal safety.
Over the last years the electric vehicle (EV) market has seen a constant upward trend and demand for lithium-ion batteries has increased enormously as a result.
With increasing circulation of Lithium-ion batteries especially the thermal safety behavior became a focus of public interest. The thermal safety of a lithium-ion cell is determined by the safety of each component.
Conventional electrolytes have flash points of about 40 °C. Since lithium-ion cells easily reach temperatures above 50 °C, there is a high risk that flammable gases escape if the cell is mechanically damaged. Therefore, a safety evaluation also should include flammability test, such as flash point tests of the solvents used for the electrolytes of the lithium-ion cells.
