Lithium-ion batteries containing organic solvent have been reported to combust and explode. To reduce the flammability of the electrolyte, one uses flame retardant (FR) components as additives the to solution. Among the others, the FR-additives containingphosphorus and nitrogen were found as very effective.The research seeks to investigate new P-N containing flame retarding additives. The proposed studies will include the synthesis of these additives, determination of the electrochemical properties of lithium-ion battery electrolytes containing them, studiesof flame retardant properties of the additives, and testing the batteries with the electrolytes. Lithium-ion batteries combine high energy and power with the potential for extended cycle life needed for many applications. However, in order to make them a practical reality, especially for high-capacity batteries, a safety issue is of great importance.The proposed program is aimed at achieving this by the decreasing of the combustion danger of lithium-ion batteries.
