The electrochemical cell may comprise an electrode (e.g., a cathode) comprising a protective layer comprising a species comprising a conjugated, negatively-charged ring comprising a nitrogen atom and/or a reaction product thereof.
Abstract: Methods for electrically coupling electrode portions within electrochemical devices, and associated articles and systems, are generally described. In some cases, an electrically non-conductive layer is between multiple electrode portions that are to be coupled. In some cases, the method comprises penetrating the article to establish electrical coupling between the electrode portions previously separated by the electrically non-conductive layer.
Abstract: Articles containing electrodes and current collectors arranged such that at least one electrode can be electronically isolated from other components of the article and/or an electrochemical device, and associated systems and methods, are provided. In some cases, the articles contain substrates for which a change in volume of the substrate causes at least one electrode to become electronically isolated from other components of the article and/or an electrochemical device. In certain cases, heating the substrate causes the change in volume of the substrate. Articles and electrochemical devices containing electrodes, current collectors, heaters, and/or sensors and associated systems and methods, are also provided. Electrochemical devices containing electrodes and current collectors arranged in a folded configuration, and associated articles, systems and methods, are also provided.

Abstract: Articles and electrochemical devices containing electrodes, current collectors, heaters, and/or sensors and associated systems and methods, are provided. The sensors, when present, may be temperature sensors or pressure sensors. In some cases, the heaters and/or sensors are adjacent to the article or electrochemical device. In certain cases, the heaters and/or sensors are thin films that are integrated into the article or electrochemical device.
Abstract: Systems and methods for applying pressure to electrochemical devices are generally described. In some aspects, batteries including an electrochemical cell and an associated deformable solid are provided. The deformable solid may be configured to apply an anisotropic force (e.g., during cycling), which may improve the performance and/or durability of the electrochemical cell. In some instances (for example, in certain cases where the deformable solid includes a piezoelectric array and/or an electroactive polymer), the battery may be able to make dynamic adjustments to a pressure experienced by the electrochemical cell (e.g., based on signals from a pressure sensor). The systems and methods described herein can, in some instances, provide for relatively uniform pressure distributions across an electrochemical cell and/or throughout a stack of multiple electrochemical cells.

Abstract: Articles and methods including layers for protection of electrodes in electrochemical cells are provided. As described herein, a layer, such as a protective layer for an electrode, may comprise a plurality of particles (e.g., crystalline inorganic particles, amorphous inorganic particles). In some aspects, at least a portion of the plurality of particles (e.g., inorganic particles) are fused to one another. For instance, in some aspects, the layer may be formed by aerosol deposition or another suitable process that involves subjecting the particles to a relatively high velocity such that fusion of particles occurs during deposition. In some cases, the protective layer may be porous.
