Abstract
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. The ESD includes at least two sub-stacks, where the elements of each respective sub-stack are electrically coupled in series with other elements of the sub-stack. The sub-stacks may be placed in a single stack, and the sub-stacks may be electrically coupled in parallel, in series, or both, with other sub-stacks to create an ESD with a particular voltage and current capacity. The entire stack may be contained by a single pair of end caps.
