Abstract
A battery includes one or more protection layers, applied to one or more foil layers in the battery, which restrict electronic transport across the protection layer based on exposure to particular physical conditions. The protection layer can change from being an electrically conductive layer to being an electrically insulating layer based on the exposure. The protection layer can include a mixture of materials that change state to electrically insulating states based on exposure to various particular physical conditions. A battery can include multiple protection layers that restrict electronic transport based on exposure to different physical conditions. A protection layer applied to a foil layer that is applied to an electrode restricts electronic transport between the foil layer and the electrode based on exposure to the one or more physical conditions. A protection layer located between separate battery cells can restrict electronic transport between portions of separate battery cells.
