An apparatus including a plurality of adjacent repeated base units, each base unit formed from an active electrode of first, second and third touch sensor arrays, the first, second and third touch sensor arrays each including a plurality of active electrodes connected to a respective common terminal of the touch sensor array, wherein each base unit includes an active electrode of the second touch sensor array interlaced between an active electrode of the first touch sensor array and an active electrode of the third touch sensor array such that a swipe touch gesture applied to two or more adjacent active electrodes of the apparatus generates signalling at the respective common terminals of the corresponding touch sensor arrays which allows the direction of the swipe touch gesture to be determined.

Apparatus and associated methods

A single-material battery is prepared using Li10GeP2S12 as the electrolyte, anode, and cathode, based on the Li-S and Ge-S components in Li10GeP2S12 acting as the active centers for its cathode and anode performance, respectively. The single-Li10GeP2S12 battery exhibits a remarkably low interfacial resistance due to the improvement of interfacial contact and interactions, and the suppression of interfacial strain/stress.

The disclosure is related to battery systems. More specifically, embodiments of the disclosure provide a nanostructured conversion material for use as the active material in battery cathodes. In an implementation, a nanostructured conversion material is a glassy material and includes a metal material, one or more oxidizing species, and a reducing cation species mixed at a scale of less than 1 nm. The glassy conversion material is substantially homogeneous within a volume of 1000 nm3.

Nanostructured materials for electrochemical conversion reactions

Provided herein are energy storage device cathodes with high capacity electrochemically active material including compounds that include iron, fluorine, sulfur, and optionally oxygen. Batteries with active materials including a compound of the formula FeF a S b O c exhibit high capacity, high specific energy, high average discharge voltage, and low hysteresis, even when discharged at high rates. Iron, fluorine, and sulfur-containing compounds may be ionically and electronically conductive.

Iron, fluorine, sulfur compounds for battery cell cathodes

A membrane electrode assembly (MEA) (250) having a nano-tubular patterened structure and having solid (instead of porous) electrode layers (206,202) is provided. Increased mechanical strength is provided by the use of solid electrode layers (206,202). The electrode layers (206,202) are sufficiently thin to permit the flow of reactants to the ebctrolyte (204). The nano-tubular pattern includes multiple closed-end tubes and increase the reaction area to vulume ratio of the MEA (250). The nano-tubular pattern also serves to increase mechanical strength, especially in a preferred honey-comb like arrangement of the closed-end tubes. A catalyst (210,208) is preferably disposed on the anode and cathode surfaces (230,220) of the MEA (250), and is preferably in the form of separated catalyst islands in order to increase reaction area. MEAs (250) according to the invention can be fabricated by layer deposition on a patterned. Atomic layer deposition is a preferred deposition technique.
