摘要： The present disclosure relates to a binder solution for an all-solid-state battery and an all-solid-state battery comprising the same and having a uniform binder distribution. The binder solution may comprise: a binder including a fluorine-based polymer; a first solvent; and a second solvent. A Hansen solubility index difference value (Ra) between the fluorine-based polymer and the first solvent is about 10 or less, and a Hansen solubility index difference value (Ra) between the first solvent and the second solvent is about 7 or less.

摘要： A system for analyzing a solid-state battery and a lithium rechargeable battery such as a lithium ion battery, and an analysis method using the system are proposed. The analysis system for a lithium secondary battery includes a housing having an accommodation space therein, and a lithium secondary battery accommodated in the accommodation space of the housing and being chargeable and dischargeable, in which the lithium secondary battery includes: an electrolyte part. The system also includes a first electrode part positioned on a side of the electrolyte part, and a second electrode part positioned on another side of the electrolyte part, in which the electrolyte part includes a matrix including a solid electrolyte having conductivity for lithium ions, one or more reference electrodes inserted in the matrix, and one or more SoC adjusters inserted in the matrix at a predetermined distance in a width direction from the reference electrode.
