  • Exhaust gas analysis method and exhaust gas analysis system
    Patent number: 10995689
    Abstract: In order to separately evaluate an influence degree of fuel and an influence degree of lubricating oil with respect to particulate matters contained in exhaust gas, an exhaust gas analysis method includes: analyzing particulate matters contained in the exhaust gas exhausted from an engine, thereby making it possible to analyze the particulate matters derived from the lubricating oil by using isooctane as a fuel.
    Type: Grant

  • Electric storage device and positive electrode
    Publication number: 20180366729
    Abstract: An electric storage device is provided with a positive electrode having a positive-electrode mixture layer including a positive-electrode active material. The positive-electrode active material includes a lithium-vanadium-phosphate from 8% to 70% by mass and a lithium-nickel complex oxide from 20% to 82% by mass. A coating concentration of the positive-electrode mixture layer is from 4 mg/cm2 to 20 mg/cm2. The lithium-nickel complex oxide includes a nickel element from 0.3 mol to 0.8 mol with respect to a lithium element of 1 mol.
