Abstract
A hybrid electrochemical device including at least two electrically connected solid-state electrochemical cells is provided. Each electrochemical cell includes a first outer electrode having a first current collector and a first electroactive layer, a second outer electrode having a second current collector and a second electroactive layer, and one or more intervening electrodes disposed between the electroactive layers. At least one of the intervening electrodes includes one or more capacitor additives. The first outer electrode is electrically connected to at least one of the intervening electrodes in a first electrical configuration. The second outer electrode is electrically connected to at least one of the intervening electrodes in a second electrical configuration. The at least two electrochemical cells are electrically connected in a third electrical configuration. The first and second electrical configurations are the same and the third electrical configuration is distinct from the first and second electrical configurations.
