Abstract: A rugged, ergonomic integrated telecommunications handset includes an electronic controller that interoperates and controls the universal remote control (URC), which connects to multiple radios simultaneously. The controller downloads options which are implemented by the controller. The handset has an ability to vibrate in a silent mode, and has a memory capacity, as well as GPS capacity. Ergonomically, the handset has a pair of side arrays of protruding ribs, which enhance gripping, preventing the handset from falling out of the user's hands, even if the user has gloves on in inclement weather conditions in the field. While compatible with the latest radio system software defined dual net and dual channel radio equipment, the handset is also backward compatible with single radios or with two or more separate radios, and may communicate using Bluetooth.

Abstract: The present disclosure relates to chemical treatments for preparing metal electrodes, including ex-situ chemical treatments for preparing metal electrodes and to ex-situ chemically treated metal electrodes, which can be used in electrochemical cells. The present disclosure also relates to methods for forming a metal fluoride-based layer (e.g. a SEI fluoride layer) on a metal or an electrode thereof comprising an ex-situ chemical treatment of the metal or electrode thereof, and to electrochemical cells comprising the ex-situ chemically treated metal electrodes.

Abstract: A process for removing impurities from a crystallized metal sulfate, including contacting crystallized metal sulfate with a liquor rich in metal sulfate. The metal may be cobalt, nickel, or manganese, and the impurities may be magnesium or calcium. The liquor rich in metal sulfate may be an overflow liquor from crystallization of the metal sulfate, and said overflow liquor may be subject to one or more impurities removal steps prior to contacting the crystallized metal sulfate, such that the overflow liquor contains lower levels of impurities than the crystallized metal sulfate to be contacted. A counter-current wash circuit may be used to remove impurities from a crystallized metal sulfate, whereby a plurality of washing tanks are configured to receive crystallized metal sulfate in a sequence, and washing liquor in reverse of said sequence.

Abstract: The invention provides a lithium-sulfur electric current producing cell comprising an anode; electrolyte; and cathode, where the cathode comprises a polymer-sulfur composite comprising: 5 to 80 wt % sulfur; 0 to 90 wt % conductive polymer; 0 to 50 wt % of one or more conductive agents, other than the conductive polymer; and 0.5 to 20 wt % a first dopant comprising a negatively charged organic polymer; wherein the conductive polymer is doped with the first dopant.

Abstract: Disclosed is a polymer electrolyte for use in an electrochemical device. Said polymer electrolyte comprises at least one polymer having ion-exchangeable functional groups. The polymer also comprises ionic liquid functional groups. The ion-exchangeable functional groups comprise a polymer-bound anionic group, such as a sulfonate, a carboxylate, and a phosphonate or any anionic surfactant group. Also disclosed is an electrical device that comprises said polymer electrolyte material. Such electrical device preferably consists of a fuel cell, an electrical battery, a super capacitor, an electrochromic window or a solar cell.

Abstract: An electrochemical element for use at a high temperature has a cathode comprising an intercalation material as active material, an anode and an electrolyte arranged between the cathode and anode, which electrolyte comprises an ionic liquid with an anion and a cation, which cation comprises a pyrrolidinium ring structure comprising four Carbon atoms and one Nitrogen atom. Experiments revealed that rechargeable batteries comprising N—R1—N—R2-pyrrolidinium, wherein R1 and R2 are alkyl groups and R1 may be methyl and R2 may be butyl or hexyl, are particularly suitable for use at a temperature of up to about 150 degrees Celsius and may be used in oil and/or gas production wells.

Abstract: The invention relates to a rechargeable battery based on lithium metal as anode. The rechargeable lithium metal battery according to the invention comprises an electrolyte and also chlorine and fluorine containing compounds: The battery according to the invention has, in particular, a strongly improved Coulomb efficiency of the metallic lithium. In addition, due to gel formation, a much safer system is formed than with liquid electrolyte.
