  • Nonaqueous liquid electrolyte
    Patent number: 9780410
    Abstract: A nonaqueous liquid electrolyte for an energy storage device that utilizes at least one of an oxidation reaction and a reduction reaction of magnesium, the nonaqueous liquid electrolyte includes an ether solvent, magnesium halide serving as an electrolyte, and aluminum halide serving as an additive, the magnesium halide and the aluminum halide being dissolved in the ether solvent.

  • Aligned carbon nanotube assembly, carbon-based electrode, power storage device, and method of manufacturing aligned carbon nanotube assembly
    Patent number: 9466436
    Abstract: The present invention provides an aligned carbon nanotube assembly constituted of carbon nanotubes each having a defective pore on its side surface, a method of manufacturing the aligned carbon nanotube assembly, a carbon-based electrode, and a power storage device. The aligned carbon nanotube assembly is formed by aggregating a large number of carbon nanotubes aligned in parallel along the same direction and having parallel orientation. In such a state that the aligned carbon nanotube assembly remains grown, the carbon nanotube constituting the aligned carbon nanotube assembly has a defective pore on its side surface. In a raman spectrum of the aligned carbon nanotube assembly in a Raman spectrometric method, when intensity of scattered light in D-band is represented by ID and intensity of scattered light in G-band is represented by IG, an ID/IG ratio is not less than 0.80.
