Abstract
Official abstract text for this publication.
A sulfide-based solid electrolyte includes secondary particles in which primary particles are agglomerated. With the use of the sulfide-based solid electrolyte, a uniform, stable, and high-quality slurry in which the primary particles have a strong interparticle binding force can be prepared.
First claim
Opening claim text (preview).
What is claimed is: 1 . A sulfide-based solid electrolyte comprising: secondary particles in which primary particles are agglomerated, wherein interparticle binding force ε of the primary particles is greater than or equal to 0.3 min·W·μm/mg. 2 . The sulfide-based solid electrolyte of claim 1 , wherein a strain Δ∂ represented by Equation 1 below is less than or equal to 55 μm −1 , Δ ∂ = ∑ i = 0.001 μ m 1 μ m ( vol % of i after ) particle size i after ) - ∑ i = 0.001 μ m 1 μ m ( vol % of i before ) particle size i before ) [ Equation 1 ] wherein particle size before represents a median diameter D50, vol % of i before represents a volume percentage of particles with a median diameter D50 of i μm before ultrasonic treatment, and particle size i after represents a median diameter D50, and vol % of i after represents a volume percentage of particles with a median diameter D50 of i μm after the ultrasonic treatment. 3 . The sulfide-based solid electrolyte of claim 1 , wherein an initial differential weight ∂ before is less than or equal to 40 μm −1 , ∂ before = ∑ i = 0.001 μ m 1 μ m ( vol % of i before ) particle size i before ) [ Equation
