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.

Abstract: A secondary battery is provided for cycling between a charged and a discharged state, the secondary battery including a battery enclosure, an electrode assembly, carrier ions, a non-aqueous liquid electrolyte within the battery enclosure, and a set of electrode constraints. The set of electrode constraints includes a primary constraint system having first and second primary growth constraints and at least one primary connecting member, the first and second primary growth constraints separated from each other in the longitudinal direction, wherein the primary constraint array restrains growth of the electrode assembly in the longitudinal direction such that any increase in the Feret diameter of the electrode assembly in the longitudinal direction over 20 consecutive cycles of the secondary battery is less than 20%.

Abstract: An improved technique for providing electrical power to a fuel dispensing nozzle is disclosed. A plurality of conductive bands are installed around a cylindrical member, and conductive plungers and the fuel dispensing nozzle make contact with the conductive bands. As the fuel dispensing hose is twisted with respect to the nozzle, the conductive bands rotate but nonetheless remain in contact with the conductive plungers, thereby providing uninterrupted power to any desired electronics installed within the fuel dispensing nozzle.
