Publication number: 20130040171Abstract: An energy storage device is provided that includes a reservoir in operative communication with a positive electrode such that the positive electrode remains fully flooded, even at the top of the charge cycle. The device more particularly includes a housing receiving therein, in a coaxial manner, an ion conducting member, and a current collector member received coaxially within the ion conducting member. In this device, a first region is provided in the space between the housing and the ion conducting member and a second region is provided in the space between the ion conducting member and the current collector member. The interior of the current collector member defines a reservoir having a certain volume at least equal to the volume of the void space created in the second region during charging of the device.Type: ApplicationFiled: August 11, 2011Publication date: February 14, 2013Inventor: Robert Christie Galloway
