Abstract
The present disclosure relates to an invention directed to controlling a viscosity of a slurry used to manufacture an electrochemical device, by adjusting a particle diameter of an inorganic matter that is an ingredient of the slurry, so that a sinking rate of the inorganic particles may remarkably slow down and dispersibility may be dramatically improved, and as a result, the content of the inorganic particles may relatively increase and the inorganic particles may be uniformly distributed in a coating layer on a substrate, thereby preventing a reduction in battery performance.
Claims13
A slurry comprising inorganic particles, an organic binder polymer, and a solvent,
- wherein the inorganic particles have a diameter in a range of 0.01 μm to 15 μm, and
- the slurry has a viscosity of which a lower bound is a value obtained from the following Equation based on the diameter of the inorganic particles and an upper bound is 10,000 cP:
- η≧40 d2 [Equation 1]
- where η denotes a viscosity of a slurry, and d denotes an average diameter of inorganic particles.
