A cathode for a solid-state battery comprises a composite cathode active material formed of a layered lithium cobalt oxide (LCO) in a solid solution matrix of lithium oxide (LiO) and a cobalt oxide phase. For example, the composite cathode active material can be layered LCO in a solid solution matrix of one of LiO&#x2014;LiCoO&#x2014;CoO, LiO&#x2014;LiCoO and LiO&#x2014;CoO, with 0&#x2264;x&#x2264;0.5. The LCO is at least 80 wt. % of the composite cathode active material. The cathode is a sintered solid-state cathode wafer that is free-standing, upon which solid-state battery cells are fabricated.

Solid solution cathode for solid-state battery

A redox flow battery system including a reactive cell with an anode chamber separated from a cathode chamber separated by an ion-permeable membrane is provided. A catholyte reservoir is connected to the cathode chamber by a catholyte fluid circulation circuit. An anolyte reservoir is connected to the anolyte chamber by an anolyte fluid circulation circuit. Nitrogen sparging of reactive oxygen from the catholyte fluid in the catholyte reservoir prevents the formation of a finely divided solid precipitate in the catholyte fluid. Nitrogen may be provided from an external source of nitrogen. Nitrogen may also be provided by the in situ generation of nitrogen from air.

Process for operating a redox flow battery system

A fuel cell stack includes a membrane electrode assembly and a bipolar plate. The bipolar plate has a corrugated portion defined by an adjacent pair of proximal and distal peak portions and a sidewall segment connecting the peak portions. The sidewall segment and membrane electrode assembly at least partially define a flow channel. The sidewall segment includes a shoulder portion defining a step spaced away from the peak portions.

A fuel cell system may include a fuel cell stack having a header and active area in fluid communication with the header. The fuel cell system may also include a wedge disposed within the header and configured to alter the cross-sectional area of the header along the length of the stack such that, during operation of the stack, a flow velocity of gas through the active area is generally constant.

A battery system includes a metal oxygen battery. The metal oxygen battery includes a first electrode and a second electrode. The second electrode includes a metal material (M). The metal oxygen battery is in communication with an oxygen storage material. In certain instances, the oxygen storage material is contained within an oxygen containment unit. The metal oxygen battery and the oxygen containment unit may be in a closed-loop with respect to each other. The battery system further includes a conduit for providing fluid communication from one of the metal oxygen battery and the oxygen containment unit to the other of the metal oxygen battery and the oxygen containment unit.

A power generating system may include a plurality of bipolar plates stacked to form a fuel cell assembly having an inlet side, a non-inlet side, an inlet header extending from the inlet side to the non-inlet side, an active area, and an inlet transition area. The inlet transition area may be in fluid communication with (i) the inlet header via feed passageways formed in each of the plates and (ii) the active area. The feed passageways of the plates located proximate to the inlet side may be generally smaller and/or fewer in number than the feed passageways of the plates located proximate to the non-inlet side such that, during operation of the fuel cell assembly, a flow velocity of gas through the active area is generally constant.

The present invention relates to a flowmeter for measuring flow rate of a fluid independently of fluid viscosity or density. In at least on embodiment, the flowmeter includes an inlet, an outlet, and a cylindrical chamber. The flowmeter also includes an impeller assembly positioned within a cylindrical chamber for rotation at a variable speed. In at least one embodiment, the flow rate of the fluid is determined when a pressure differential between the fluid in the let and fluid in the outlet becomes substantially zero.

A stabilized electric distribution system for use in a vehicle having electric assist. The system electrically couples an electric assist bus to an accessory load bus while protecting the first electrical bus from electric assist and regenerative braking induced voltage variations. An energy management controller selectively controls each of a electric motor/generator, a DC/DC converter, and an alternator to affect electric energy distribution within the system. Preferably, the electric energy distribution is controlled to maintain the first electrical bus voltage within a predefined voltage range.

A method is provided for manufacturing a battery having battery electrodes and with a desired porosity, using an electrochemical model and a thermal model that includes determining energy and current requirements for a particular application. Characteristics of the battery in response to said energy and current requirements are determined. The battery characteristics and energy and current requirements are prepared for use in the electrochemical model and the thermal model The porosity of the battery electrodes is determined by solving equations within the electrochemical model and the thermal model Porosity of the battery electrodes is varied until voltage potential across the battery varies by less then a predetermined tolerance factor for an operating range state of charge. A paste mixture is created in response to the desired battery electrode porosity. The paste mixture is applied to a grid followed by curing of the grid and paste.
