  • Methods of fabricating porous ceramic electrodes for solid state battery applications
    Patent number: 11942622
    Abstract: Compositions and methods for the fabrication of electrode and porous lithium-garnet electrolyte scaffolds for use in solid state batteries and other devices are provided. The methods produce porous structures using phase inversion or high shear compaction processes to fabricate a solid-state battery electrode material from LLZO electrolytes. Engineered electrode structures with a porous scaffold of solid electrolyte material provide lower interfacial resistances and a mechanical support for a thin solid electrode layer improving performance.
    Type: Grant

  • Electrical Load Controller with Neutral Detection
    Publication number: 20140071573
    Abstract: An electrical load control device as disclosed above is capable of detecting when it has been connected to either a leakage type (two-wire) or a Neutral type (three-wire) power input and automatically adjust its operation accordingly. In leakage operation the leakage current is limited to 0.5 ma and in three-wire or neutral operation the power supply provides more current than in leakage operation. In neutral operation, one or more signals are provided to the microprocessor to enable operation of indicator or other power consuming elements.
