TL;DR: In this paper, the authors proposed a flame-retardant composition for polyurethane foams, which consisted of: (a) a phosphate ester blend comprising triphenyl phosphate and one or more alkyl-substituted triphensyl phosphates; and (b) a polyol crosslinking agent soluble in the phosphate esters blend.
Abstract: The present invention relates to flame-retardant compositions for use in polyurethane foams, the flame-retardant composition comprising: (a) a phosphate ester blend comprising triphenyl phosphate and one or more alkyl-substituted triphenyl phosphates; and (b) a polyol crosslinking agent soluble in the phosphate ester blend. The invention also relates to flexible polyurethane foams containing these flame-retardant compositions.

TL;DR: In this article, a functional electrolyte additive, triphenyl phosphate (TPPa), is proposed to form an effective cathode-electrolyte interphase (CEI) layer on the surface of Ni-rich NCM cathode material by electrochemical reactions.
Abstract: Nickel-rich lithium nickel-cobalt-manganese oxides (NCM) are viewed as promising cathode materials for lithium-ion batteries (LIBs); however, their poor cycling performance at high temperature is a critical hurdle preventing expansion of their applications. We propose the use of a functional electrolyte additive, triphenyl phosphate (TPPa), which can form an effective cathode-electrolyte interphase (CEI) layer on the surface of Ni-rich NCM cathode material by electrochemical reactions. Linear sweep voltammetry confirms that the TPPa additive is electrochemically oxidized at around 4.83 V (vs. Li/ Li) and it participates in the formation of a CEI layer on the surface of NCM811 cathode material. During high temperature cycling, TPPa greatly improves the cycling performance of NCM811 cathode material, as a cell cycled with TPPa-containing electrolyte exhibits a retention (133.7 mA h g) of 63.5%, while a cell cycled with standard electrolyte shows poor cycling retention (51.3%, 108.3 mA h g). Further systematic analyses on recovered NCM811 cathodes demonstrate the effectiveness of the TPPa-based CEI layer in the cell, as electrolyte decomposition is suppressed in the cell cycled with TPPa-containing electrolyte. This confirms that TPPa is effective at increasing the surface stability of NCM811 cathode material because the TPPa-initiated POx-based CEI layer prevents electrolyte decomposition in the cell even at high temperatures.
