Methods, systems, and devices for applying forces to electrochemical devices are generally described. In some cases, the methods include applying a force to an electrochemical device via a solid surface that, in the absence of an applied force, has at least a portion that is convex with respect to a side of the electrochemical device. Certain embodiments are related to systems and devices for applying a force to an electrochemical cell, with some of the systems and devices employing, for example, solid articles with certain shapes (e.g., convex shapes in the absence of an applied force) and/or inventive couplings.

Batteries including electrochemical cells, associated components, and arrangements thereof are generally described. In some aspects, batteries with housings that undergo relatively little expansion and contraction even in cases where electrochemical cells in the battery undergo a relatively high degree of expansion and contraction during charging and discharging are provided. Batteries configured to apply relatively high magnitudes and uniform force to electrochemical cells in the battery, while in some cases having high energy densities and a relatively low pack burden, are also provided. In certain aspects, arrangements of electrochemical cells and associated components are generally described. In some aspects, thermally conductive solid articles that can be used for aligning components of the battery are described. In some aspects, thermally insulating and compressible components for battery packs are generally described.

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.

Isolatable electrodes and associated articles and methods

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.
