More Information
Summary:A stacked energy storage device (ESD) has at least two cell segments arranged in a stack. Each cell segment may have a first electrode unit having a first active material electrode, a second electrode unit having a second active material electrode, and an electrolyte layer between the active material electrodes. Variable volume containment may be used to control the inter-electrode spacing within each cell segment. In some embodiments, one or more dynamic flexible gaskets may be included in each cell segment to seal the electrolyte within the cell segment and to deform in preferred directions. In some embodiments, hard stops may set the inter-electrode spacing of the ESD.
