ENERGY STORAGE DEVICES HAVING MONO-POLAR AND BI-POLAR CELLS ELECTRICALLY COUPLED IN SERIES AND IN PARALLEL

摘要

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 cntire stack may be contained by a single pair of end caps.
