Embodiments of the present invention are in the field of materials, apparatus, process, methods, and designs for manufacture of a thin film energy storage devices with a capacity greater then 1 mA-hr-cmincluding thin film Lithium metal and Li+ ion batteries and capacitors having high energy density and high cycle life due to the incorporation of at least one vacuum thin film with respect to protection and electrical conductivity of the electrodes, and at least one vacuum thin film electrolyte for electrical insulation of the electrodes and ion conduction after assembly for low self discharge and high cycle life battery cells.

Energy storage device with a first metal layer formed from a precursor layer upon charge and diffused into a cathode during discharge

An energy harvesting system for collecting energy from sources of thermal energy that exist in the environment and convert the energy to electricity. The system has N-P junctions mounted on the outer surface of a conduit, pipe or flue. A hot medium flows through the conduit, pipe or flue. The p-n junctions operate as thermoelectric power generators. Heat absorbed at the p-n junctions increases the kinetic energy of charge carriers causing migration of the charge carriers. This thermally-driven migration of charge carriers is used to drive an electrical current in an external circuit.

Thermoelectric coatings for waste heat recovery and photo-thermal power

A method for producing a multi-layer bipolar coated cell according to one embodiment includes applying a first active cathode material above a substrate to form a first cathode; applying a first solid-phase ionically-conductive electrolyte material above the first cathode to form a first electrode separation layer; applying a first active anode material above the first electrode separation layer to form a first anode; applying an electrically conductive barrier layer above the first anode; applying a second active cathode material above the anode material to form a second cathode; applying a second solid-phase ionically-conductive electrolyte material above the second cathode to form a second electrode separation layer; applying a second active anode material above the second electrode separation layer to form a second anode; and applying a metal material above the second anode to form a metal coating section. In another embodiment, the anode is formed prior to the cathode. Cells are also disclosed.

Multi-layer coatings for bipolar rechargeable batteries with enhanced terminal voltage

An electrical cell apparatus includes a first current collector made of a multiplicity of fibers, a second current collector spaced from the first current collector; and a separator disposed between the first current collector and the second current collector. The fibers are contained in a foam.

Method of making super capacitor with fibers

Super capacitor with fibers

The invention relates to a portable cartridge that stores a fuel for use with a fuel cell system. Cartridges described herein improve mechanical interface between a cartridge and a device that couples to the cartridge. The interface may include one or more of: a sliding interface between a cartridge and device, a latching interface that holds the cartridge in one or more positions relative to the device, and/or keyed access and security features that prevent unintended access to the fuel. Multiple valves may also be included to further control access to the fuel.

Fuel cartridge connectivity

A portable cartridge that stores a fuel for use with a fuel cell system includes one or more disposable components for use by the fuel cell system. The disposable component may be included on a fuel cartridge, but used by a fuel cell system when the cartridge and a package that includes the system are coupled together. The disposable component may include: an inlet filter that regulates passage of gases and liquids into the fuel system, an outlet filter that cleans fuel cell system exhaust gases, a sensor on the inlet air stream to the fuel cell system; a sensor on the exhaust; a desiccant that sinks moisture from within the fuel cell system package; or a fuel absorbent that soaks fuel between connectors on the fuel cartridge and the fuel cell system.

Disposable component on a fuel cartridge and for use with a portable fuel cell system

Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision.
