Abstract

A energy storage device for cycling between a charged state and a discharged state, the energy storage device including an enclosure, an electrode assembly and a non-aqueous liquid electrolyte within the enclosure, and a constraint that maintains a pressure on the electrode assembly as the energy storage device is cycled between the charged and the discharged states.
