This short research presents an introduction to the fire safety of Lithium-ion batteries. Nowadays, as the most weak part of aprotic battery is its aprotic electrolyte. The aprotic electrolyte (commonly the mixture of aprotic solvents) that is used in Lithium-ion batteries have got low flash point with poor thermal stability. This paper describes using sulfolane as an aprotic solvent in Lithium-ion battery. Measurements were focused on performance, cyclability and stability of aprotic electrolyte with relation of graphite material as a negative electrode. Like a possible substitution of graphite, the LTO material was used and tested. Lithium Titanate Oxide (LTO) seems to be promising negative electrode material for Lithium-ion batteries.
