Optimized device for determination of self-extinguishing time developed. Pentafluoro(phenoxy)cyclotriphosphazene as flame retardant electrolyte additive. Electrolyte mixture with 5% of FPPN is non-flammable for 10s. Exothermic reactions are shifted by 21 °C to higher temperatures by using FPPN. FPPN is electrochemical stable and high amounts are still present after 500 cycles.
