Abstract: An electrode has a first active material layer between a current collector and a separator. The first active material layer comprises an active electrode material and electrically actuated fibers extending from a surface of the current collector and into the active electrode material. The electrically actuated fibers have an actuated state, in which the electrically actuated fibers change dimension in a linear direction under application of an electric field, the electrically actuated fibers configured to direct electrons through the active electrode material in a stacked direction of the electrode, and an unactuated state, in which the electrically actuated fibers are conductive but remain in an original state.

Abstract: A stress detector for detecting an in-situ stress profile of an electrode has a liquid cell, a holder configured to attach to one end of a sample electrode so that the sample electrode is cantilevered in the liquid cell, a piezo sensor comprising a piezo material in the liquid cell and having a movable end configured to contact the sample electrode and a fixed end fixedly engaged within the liquid cell and a measurement sensor in contact with the piezo sensor.

Abstract: A method of preparing shape-controlled alloy particles includes dissolving a solvent in a surfactant selected to inhibit particle growth; adding a noble metal precursor and a transition metal precursor to form a mixture; irradiating the mixture with a microwave under reflux for about thirty minutes or less at an irradiation temperature of between 185° C. and 195° C.; cooling the mixture; and drying the mixture at a temperature of between 55° C. and 65° C. to obtain shape-controlled alloy particles having a uniform shape, the shape dependent upon the surfactant used.
