Abstract
A manufacturing method of a particle aggregate aggregated with wet particles in which active material particles and conductive particles are evenly dispersed and a manufacturing method of an electrode body including the particle aggregate are provided. The manufacturing method of a particle aggregate includes a first step of obtaining a first mixture by mixing conductive particles with a binder dispersion in which binder is dispersed in a dispersion medium, a second step of obtaining a clay-like mixture by kneading the first mixture with active material particles, and a third step of obtaining the particle aggregate aggregated with wet particles formed of the clay-like mixture.
Claims8
A particle aggregate in which wet particles including active material particles, conductive particles, binder, and a dispersion medium are aggregated, wherein
- the wet particles are formed of a clay-like mixture, and
- the particle aggregate has a shear pressure of 0.3 MPa or less in a ductility test of pressing the particle aggregate with a pressure of 2.0 MPa and measuring a shear stress required for displacing the particle aggregate by 1.0 mm in an orthogonal direction perpendicular to a pressing direction.
