TL;DR: In this article, the fundamental properties of trimethyl phosphate (TMP)-based electrolytes with LiPF 6 as solute were investigated for natural graphite anode and LiCoO 2 cathodes.
Abstract: To develop nonflammable electrolytes for lithium-ion batteries, the fundamental properties of trimethyl phosphate (TMP)-based electrolytes with LiPF 6 as solute were investigated for natural graphite anode and LiCoO 2 cathodes, It was found that the TMP solvent had good oxidation stability and poor reduction stability, which led to TMP reduction decomposition on the natural graphite electrode at the negative potential of 1.2 V. To solve this problem, ethylene carbonate (EC). propylene carbonate (PC), and diethyl carbonate (DEC) cosolvents were mixed with TMP solvent. As a result, the reduction decomposition of the TMP solvent was considerably suppressed in < 10% TMP containing EC + PC + TMP and <25% TMP containing EC + DEC + TMP electrolytes due to the formation of good solid electrolyte interphase film on natural graphite electrode in these two mixed electrolytes. The nonflammability of the TMP electrolyte declined with mixing flammable cosolvents, which was explained by a flame retarding mechanism involving a hydrogen radical trap in the gas phase. According to this mechanisms it was deduced that the cosolvents with high boiling point and fewer hydrogen atoms were promising for nonflammability of mixed electrolytes Furthermore, a thermal test disclosed that the thermal stability of lithium-ion cells may be improved by using TMP-containing electrolytes.

TL;DR: In this article, a separator is impregnated with an electrolyte, which contains halogenated ethyl carbonate such as 4-fluoro-1,3-dioxolane and a phosphorus-containing compound such as trimethyl phosphate.
Abstract: PROBLEM TO BE SOLVED: To provide a battery capable of enhancing high temperature characteristics. SOLUTION: A separator is impregnated with an electrolyte. The electrolyte contains a solvent and an electrolyte salt. The solvent contains halogenated ethyl carbonate such as 4-fluoro-1,3-dioxolane and a phosphorus-containing compound such as trimethyl phosphate. Thereby, chemical stability at high temperature can be increased. By furthermore containing vineylene carbonate as the solvent, higher effect can be obtained. COPYRIGHT: (C)2007,JPO&INPIT

TL;DR: In this paper , a controlled electrolytic method for a monolithic solid-electrolyte interphase (SEI) via a high dipole moment solvent dimethyl methylphosphonate (DMMP) was proposed.
Abstract: Abstract Zinc metal battery (ZMB) is promising as the next generation of energy storage system, but challenges relating to dendrites and corrosion of the zinc anode are restricting its practical application. Here, to stabilize Zn anode, we report a controlled electrolytic method for a monolithic solid‐electrolyte interphase (SEI) via a high dipole moment solvent dimethyl methylphosphonate (DMMP). The DMMP‐based electrolytes can generate a homogeneous and robust phosphate SEI (Zn3(PO4)2 and ZnP2O6). Benefiting from the protecting impact of this in situ monolithic SEI, the zinc electrode exhibits long‐term cycling of 4700 h and a high Coulombic efficiency 99.89 % in Zn|Zn and Zn|Cu cell, respectively. The full V2O5|Zn battery with DMMP‐H2O hybrid electrolyte exhibits a high capacity retention of 82.2 % following 4000 cycles under 5 A g−1. The first success in constructing the monolithic phosphate SEI will open a new avenue in electrolyte design for highly reversible and stable Zn metal anodes.
