Abstract
A slurry manufacturing apparatus includes a rotation-revolution mixing device which mixes and prepares a slurry by rotational movement and revolving movement and a gas injection mechanism which dissolves carbonic acid gas in the slurry prepared by the rotation-revolution mixing device, in which the gas injection mechanism dissolves the carbonic acid gas in the slurry by injecting the carbonic acid gas under pressure in a sealed state.
Claims11
A slurry manufacturing apparatus for manufacturing a slurry for a positive electrode of a nonaqueous electrolyte secondary battery containing an alkali metal complex oxide, the apparatus comprising:
- a rotation-revolution mixing device which mixes and prepares a slurry by rotational movement and revolving movement;
- and
- a gas injection mechanism which dissolves carbonic acid gas in the slurry prepared by the rotation-revolution mixing device,
- wherein the gas injection mechanism dissolves the carbonic acid gas in the slurry by injecting the carbonic acid gas under pressure in a sealed state.
A slurry manufacturing method for manufacturing a slurry for a positive electrode of a nonaqueous electrolyte secondary battery containing an alkali metal complex oxide, the method comprising:
- a rotation-revolution mixing step of mixing and preparing a slurry by rotational movement and revolving movement;
- a gas injection step of dissolving carbonic acid gas in the slurry prepared by the rotation-revolution mixing step;
- and
- a deaerating step of deaerating the carbonic acid gas from the slurry having undergone the gas injection step,
- wherein in the gas injection step, the carbonic acid gas is dissolved in the slurry by injecting the carbonic acid gas under pressure in a sealed state.
