A method of generating electrical energy using an electrochemical direct heat to electricity converter operating on the Rankine cycle is provided. The converter includes a working fluid, a high temperature electrochemical cell including a first membrane electrode assembly, a low temperature electrochemical cell including a second membrane electrode assembly, an evaporator coupled to the first electrochemical cell, a condenser coupled to the second electrochemical cell, and an external load. The method involves introducing the working fluid at the first membrane electrode assembly as a liquid, expanding the working fluid through the first membrane electrode assembly and evaporating it into a vapor, and cooling and condensing the vapor back into a liquid at the second membrane electrode assembly.

Halogen-based thermo-electrochemical converter

A heat to electricity converter including a working fluid and a pair of membrane electrode assemblies (MEA) is provided. Each MEA includes a pair of electrodes which are electron conductive and permeable to the working fluid, and a thin film electrolyte membrane sandwiched between the electrodes. The membrane is conductive of ions of the working fluid and has a thickness of 0.03 &#x3bc;m to 10 &#x3bc;m. At least one electrode of each MEA includes a non-porous and dense metal. One electrode of each MEA is in contact with the working fluid at a first, higher pressure, while the other electrode is in contact with the working fluid at a second, lower pressure. The first MEA is configured to compress the working fluid from the second pressure to the first pressure, while the second MEA is configured to expand the working fluid from the first pressure to the second pressure.

Thermo-electrochemical converter having dense metal electrode

Solid-state batteries, battery components, and related processes for their production are provided. The battery electrodes or separators contain sintered electrochemically active material, inorganic solid particulate electrolyte having large particle size, and low melting point solid inorganic electrolyte which acts as a binder and/or a sintering aid in the electrode.

Solid-state batteries, separators, electrodes, and methods of fabrication

A high capacity solid state composite cathode contains an active cathode material dispersed in an amorphous inorganic ionically conductive metal oxide, such as lithium lanthanum zirconium oxide and/or lithium carbon lanthanum zirconium oxide. A solid state composite separator contains an electronically insulating inorganic powder dispersed in an amorphous, inorganic, ionically conductive metal oxide. Methods for preparing the composite cathode and composite separator are provided.

Embodiments of solid-state batteries, battery components, and related construction methods are described. The components include one or more embodiments of a low melt temperature electrolyte bonded solid-state rechargeable battery electrode and one or more embodiments of a composite separator having a low melt temperature electrolyte component. Embodiments of methods for fabrication of solid-state batteries and battery components are described. These methods include co-extrusion, hot pressing and roll casting.

Solid-state battery separators and methods of fabrication

Solid-state battery electrodes

Amorphous lithium lanthanum zirconium oxide (LLZO) is formed as an ionically-conductive electrolyte medium. The LLZO comprises by percentage of total number of atoms from about 0.1% to about 50% lithium, from about 0.1% to about 25% lanthanum, from about 0.1% to about 25% zirconium, from about 30% to about 70% oxygen and from 0.0% to about 25% carbon. At least one layer of amorphous LLZO may be formed through a sol-gel process wherein quantities of lanthanum methoxyethoxide, lithium butoxide and zirconium butoxide are dissolved in an alcohol-based solvent to form a mixture which is dispensed into a substantially planar configuration, transitioned through a gel phase, dried and cured to a substantially dry phase.
