First Claim
1. An energy storage device comprising:
- a stack of a plurality of electrode units, the stack comprising;
a first sub-stack of a plurality of bi-polar electrode units;
a second sub-stack of a plurality of bi-polar electrode units collinear with the first stack; and
a mono-polar electrode unit positioned between the first sub-stack and the second sub-stack;
a first end cap at a first end of the stack of electrode units; and
a second end cap at a second end of the stack of electrode units.

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.
