摘要: 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.

摘要: 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.

摘要: 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.

摘要: An electrode structure and its method of manufacture are disclosed. The disclosed electrode structures may be manufactured by depositing a first release layer on a first carrier substrate. A first protective layer may be deposited on a surface of the first release layer and a first electroactive material layer may then be deposited on the first protective layer. Subsequently, the first carrier substrate may be delaminated from the first release layer. The first release layer may then be removed from the first protective layer by dissolution in an electrolyte. The first protective layer may have a low mean peak to valley surface roughness and/or may be thin. In some embodiments, an interface between the first protective layer and the first electroactive material layer has a low mean peak to valley surface roughness. In some embodiments, a thickness of the first protective layer is greater than a mean peak to valley roughness of the first release layer. In some embodiments, an adhesive strength between the first release layer and the first protective layer is greater than an adhesive strength between the first release layer and the first carrier substrate.
