  • Fire-safety Improvement Technology for Lithium-ion Batteries

    The use of lithium-ion batteries has been expanding rapidly due to their high energy density. On the other hand, since organic solvents are used in lithium-ion batteries, it is important to ensure their fire safety. With this study, we focus on the combustion phenomenon of organic solvents and study combustion inhibition technology.

    Research

    The use of lithium-ion batteries has been expanding rapidly due to their high energy density. On the other hand, since organic solvents are used in the battery electrolyte, it is important to ensure their fire safety. With this study, we intend to develop a method to quantify the effect of adding a combustion inhibitor to suppress the combustion of organic solvents, search for additives that are effective in suppressing combustion, and study the effect of the lithium salt contained in the electrolyte itself on the flammability of organic solvents. We also conduct modeling and numerical analysis of fire phenomena taking the elementary reaction kinetics of combustion in an electrolyte into consideration.
