SOLID ELECTROLYTE OF FINE PARTICLE, COMPOSITION CONTAINING SOLID ELECTROLYTE OF FINE PARTICLE, ELECTRODE LAYER AND ELECTROLYTE LAYER FORMED OF THE SAME AND LITHIUM-ION BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a composition containing electrolyte particles which hardly cause the aggregation of primary particles and have an extremely small particle diameter.

SOLUTION: A composition contains solid electrolyte fine particles and a solvent. The solid electrolyte fine particle contains at least a sulfur element and a lithium element, and in which a volume-based average particle diameter measured with a particle-size distribution measuring method of a laser diffraction type is 0.5 μm or less and 90% or more of the particles have a volume-based particle diameter of 1.5 μm or less.
