Latest Patents

Materials and Methods of Producing Lithium Cobalt Oxide Materials of a Battery Cell. This invention describes lithium cobalt oxide materials doped with one or more metals, along with methods and equipment for producing them. The process digitally or otherwise controls the molar proportions of lithium-, cobalt-, and dopant-containing salts in a liquid mixture. A mist of the mixture is dried into solid particles, which are then annealed to produce crystallized lithium cobalt oxide. The described system includes a mist generator, drying chamber, gas-solid separators, and reactors.

Large-Scale Synthesis of Powders of Solid-State Electrolyte Material Particles for Solid-State Batteries, Systems and Methods Thereof. This invention concerns producing solid-state electrolyte materials with a desired chemical composition at large scale. Lithium-containing and inorganic salts are prepared in solutions, and their molar ratios are digitally controlled before the mixture is dried and processed into powder. Annealing produces crystalline electrolyte particles. The apparatus includes a mist generator, a jetting chamber, gas-solid separators, and reactors.

Career Highlights

Liu’s patent work addresses two important battery-material challenges: producing compositionally controlled lithium cobalt oxide and scaling the manufacture of solid-state electrolyte powders. Both inventions describe processes that combine controlled solution preparation, mist-based drying, particle separation, and annealing.
