Abstract

The flame retardant (FR) additive hexa-methoxy-cyclo-tri-phosphazene [NP(OCH₃)₂]₃ was synthesized using the literature procedures. The electrochemical and thermal properties of Li-ion electrolytes containing hexamethoxy-cyclo-tri-phosphazene additive were measured using cyclic voltammetry and accelerating rate calorimetery. The effect of this additive on the electrochemical performance of Li-ion cells was investigated in Li_xC/Li_1-xNi_0.8Co_0.2O₂ type coin cells
