ELECTROCHEMICAL DEVICES AND RELATED ARTICLES, COMPONENTS, CONFIGURATIONS, AND METHODS

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.
