SLURRY WTH IMPROVED DISPERSIBILITY AND ITS USE |
摘要 |
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. |

1. 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. |
