Abstract
(EN)
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.

L'invention concerne des articles contenant des électrodes et des collecteurs de courant agencés de sorte qu'au moins une électrode peut être électroniquement isolée par rapport à d'autres composants de l'article et/ou d'un dispositif électrochimique, ainsi que des systèmes et des procédés associés. Dans certains cas, les articles contiennent des substrats pour lesquels un changement de volume du substrat entraîne l'isolation électronique d'au moins une électrode par rapport à d'autres composants de l'article et/ou d'un dispositif électrochimique. Dans certains cas, le chauffage du substrat provoque le changement de volume du substrat. L'invention concerne également des articles et des dispositifs électrochimiques contenant des électrodes, des collecteurs de courant, des éléments chauffants et/ou des capteurs, ainsi que des systèmes et des procédés associés. L'invention concerne également des dispositifs électrochimiques contenant des électrodes et des collecteurs de courant agencés dans une configuration repliée, et des articles, des systèmes et des procédés associés.
