The present disclosure provides a composition for purifying water comprising a magnesium oxide component and a binder. The magnesium oxide component includes magnesium oxide, a pH regulator, and an additional water purifying material. The binder can be an organic polymer, an inorganic binder, or a combination of both.

Water purification compositions of magnesium oxide and applications thereof

A method of producing lithium metal oxides can include mixing lithium salt and a metal oxide to form a composition, heating the composition in a first reactor, transferring the composition to a second reactor, and passing the composition through the second reactor to anneal the composition to form lithium metal oxides. The second reactor can be a fluidized bed reactor. The lithium metal oxide can have an average crystal size of between about 5 microns and about 20 microns.

Process for the preparation of lithium metal oxides involving fluidized bed techniques

A method for reducing pressure build-up in an electrochemical cell is provided comprising: providing an anhydrous nonaqueous electrolyte solution comprising at least one quaternary ammonium salt and at least one anhydrous nonaqueous solvent; contacting the electrolyte solution with at least one acid scavenger; and loading the nonaqueous electrolyte solution into the electrochemical cell. Also, provided is an electric double-layer capacitor (supercapacitor) comprising a free acid scavenger.

High voltage electrolytes

Disclosed is a processes for the production of relatively high purity alkaline earth metal oxides, such as SrO, from relatively low purity forms of carbonated or other oxygenated forms of such metals, such as strontium carbonate. The relatively low purity material is exposed to conditions under which at least a portion of the metal contained therein is converted to a salt that is more readily solvated in a provided solvent than the starting material, while at the same time not substantially increasing the solubility of at least one or more of the impurities in such selected solvent. This step is then preferably followed by removal of solid or otherwise un-dissolved impurities from the solution. After the removal step, the solution is preferably exposed to conditions effective to form a relatively insoluble salt of the alkaline earth metal, such as a strontium salt. The insoluble salt is also preferably one that can be readily and effectively converted to the desired alkaline earth metal oxide, preferably SrO. A novel preferred thermal decomposition step disclosed.

Process for the manufacture of tetraalkylammonium tetrafluoroborate-containing electrolyte compositions characterized in that said process comprises step (i): (i) mixing of at least one tetraalkylammonium halide with at least one metal tetrafluoroborate in at least one organic solvent, which is partially or completely miscible with water.

Direct process for the manufacture of tetraalkylammonium tetrafluoroborate-containing electrolyte compositions

Provided are methods of purifying quaternary onium salts having the steps of (a) providing an quaternary onium salt solution having a first ionic impurity concentration; (b) providing an ion exchange material charged with electrochemically stable anions; and (c) contacting the salt solution with the ion exchange material to produce an quaternary onium salt solution having a second halide concentration is less than the first ionic impurity concentration.

Method for purifying quaternary onium salts

An electrolyte with an indicator, such as a dye, for detecting leakage from an electrochemical energy storage device is provided. Also provided is a method of making such an electrolyte with indicator; a device that incorporates such an electrolyte with indicator; a method of manufacturing an electronic or electrical system that incorporates such a device; and a method of detecting the leakage of electrolyte from a battery or capacitor.

Electrolyte with indicator
