  • Combustion system and method of using fuel composition as fuel for remodeled diesel engine
    Patent number: 10858984
    Abstract: A combustion system includes a remodeled diesel engine and a fuel composition to be added into the remodeled diesel engine. The remodeled diesel engine includes a cylinder unit, and a coating coated on the cylinder unit and containing a catalyst that is a metal, an alloy of the metal, a composite containing oxides of the metal, a salt of the metal or combinations thereof. The metal is platinum, nickel, cobalt, copper, molybdenum, and/or titanium. The fuel composition includes water, a fuel oil and an emulsifying agent. The amount of water ranges from 10 to 90 wt % based on total weight of water and the fuel oil, and the amount of the emulsifying agent ranges from 0.5 to 10 wt % relative to total weight of water and the fuel oil.
    Type: Grant

  • C2/m-structured cathode material for lithium-ion battery
    Patent number: 8663848
    Abstract: Disclosed is a C2/m-structured cathode material for a lithium-ion battery. The cathode material includes a lithium transition metal oxide represented by a formula of: Li(LiwNixCoyMnz)O2, wherein w+x+y+z=1, 0.42?z?0.60, 0.30?x+y?0.55, any of w, x, and y is larger than 0, and the cathode material having a single-phase structure with a space group of C2/m. A lithium-ion battery containing the C2/m-structured cathode material is also disclosed.
