Comparison of Flame Retardants for use in Low Flammable Electrolytes

Popis výsledku v původním jazyce

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 retardants dimethyl methyl phosphonate and triethyl phosphonate. The main physical and electrical parameters were tested namely specific conductivity, flashpoint and potential window 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 in average of 10% and the specific conductivity an average of 4%. The flame retardant triethyl phosphonate increased in the flash point in average of 7% and the specific conductivity at 30%.
