Method for producing electrode, apparatus for producing electrode, and liquid composition

An apparatus for producing an electrode, the apparatus comprising:

• a container in which a liquid composition including an active material and a dispersion medium is accommodated;
• and
• an applicator configured to apply the liquid composition onto a predetermined region of a substrate and onto a region adjacent to the predetermined region,
• wherein, during the applying, a time difference from a time when the liquid composition is applied onto the predetermined region to a time when the liquid composition is applied onto the region adjacent to the predetermined region is determined as δt,
• a viscosity η1000 of the liquid composition at a shear rate of 1,000 s−1 is 200 mPa·sec or less, and a viscosity η0.1 of the liquid composition at a shear rate of 0.1 s−1 is 1,000 mPa·sec or greater, and
• when a shear force is applied to the liquid composition at a shear rate of 1,000 s−1 for 50 seconds, followed by changing the shear rate to a shear rate of 0.1 s−1, a viscosity of the liquid composition at δt seconds after changing the shear rate to 0.1 s−1 is 300 mPa·sec or less.

A liquid composition comprising:

• an active material;
• and
• a dispersion medium,
• wherein a viscosity η1000 of the liquid composition at a shear rate of 1,000 s−1 is 200 mPa·sec or less, and a viscosity η0.1 of the liquid composition at a shear rate of 0.1 s−1 is 1,000 mPa·sec or greater.
