Low Flammable Electrolytes

conference paper

English

The use of portable and stationary batteries is a common praxis nowadays. One of the main parameters alongside with high capacity, long lifetime is the safety of lithium ion batteries. The batteries have to be safe during movement and the threat to human health is unacceptable by using device that contain batteries. In the case of stationary batteries is also the question of the protection of tangible property. This paper deal with testing standard used solvents like propylene carbonate, ethylene carbonate, dimethyl carbonate, solvents with higher flame safety like sulfolane, dimethyl sulfone and flame retardant dimethyl methyl phosphonate. The main physical and electrical parameters were tested namely specific conductivity and flashpoint with and without flame retardant. The concentration of flame retardant varied with respect to the higher safety properties and the electrical properties as well as the electrode materials compatibility. The dimethyl methyl phosphonate flames retardant increase the flashpoint an average of 10% and the specific conductivity an average of 4%.
