At this time, the consumption of phosphorus pentafluoride was 26 g. The resulting solution was heated to 50 ° C. and deaerated with a vacuum pump to remove excess phosphorus pentafluoride. Reproduction of any materials from the site is strictly forbidden without permission. The solutions of LiPF6 in alkyl carbonates find applications as electrolytes in lithium ion batteries and the use of high quality battery grade electrolytes having extremely low water (<15 ppm) and hydrogen fluoride (<50 ppm) contents are critical for achieving high electrochemical performance. Solutions of lithium hexafluorophosphate, LiPF6, in propylene carbonate (4-methyl-1,3-dioxolan-2-one; denoted by PC hereafter) in the concentration range from 0.0 to 3.29 M (M = mol dm-3) have been studied regarding their conductivities, viscosities, and self-diffusion coefficients of PC by the NMR field gradient technique, Raman spectra, and NMR spectra. In this method, a film of a reaction product is formed on the surface of lithium fluoride, and the reaction does not proceed completely, and unreacted lithium fluoride remains. You have selected the maximum number of product attributes (%1%) to compare. Lithium hexafluorophosphate solution, in ethylmethyl carbonate, 2.0 M LiPF6 EMC, battery grade. It is a white crystalline powder. The lithium hexafluorophosphate formed here has a very high solubility, so it will not dissolve in the solvent and remain as a film on the surface, so the reaction will proceed completely.

Comparative Example 2 32 g of lithium fluoride is dissolved in 500 g of hydrofluoric acid anhydride. These electrolyte solutions have extremely low water content (less than 15 ppm), please handle under inert and moisture free environment (glove box). Please remove at least one to add a new selection. do not need to formally request permission to reproduce material contained in this Lithium fluoride and phosphorus pentafluoride are reacted in an ether compound. article provided that the correct acknowledgement is given with the reproduced material. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage. Also, Since the lithium battery solvent is used as the solvent in the present invention, the solution obtained by the reaction can be directly used as the lithium battery electrolyte. 3. In contrast, at high concentrations the lithium ion is present in aggregates, but a noticeable fraction remains present as free ions. PAYMENT UNTIL: 20071008, Free format text: Specifically, solutions of lithium hexafluorophosphate in carbonate blends of ethylene carbonate, dimethyl carbonate, diethyl carbonate and/or ethyl methyl carbonate, with a small amount of one or many additives such as fluoroethylene carbonate and vinylene carbonate, serve as state-of-the-art electrolytes in lithium-ion batteries. [Specific means for solving the problem] As a result of intensive studies in view of the problems of the related art, the present invention has been achieved. It hydrolyzes near 70 °C (158 °F)[3] according to the following equation forming highly toxic HF gas: Owing to the Lewis acidity of the Li+ ions, LiPF6 also catalyses the tetrahydropyranylation of tertiary alcohols. Comparative Example 1 5.2 g of lithium fluoride was placed in a nickel reactor equipped with a stirrer, and the inside of the reactor was evacuated under vacuum.
