摘要： A method for producing a compact of an electrolyte containing a sulfonyl imide compound represented by the general formula (1) includes compressing of performing compression-granulating of the electrolyte in a powder form to obtain a sheet-shaped or strip-shaped electrolyte, and pulverizing the sheet-shaped or strip-shaped electrolyte to obtain a granular electrolyte compact, or tableting the electrolyte in a powder form to obtain a tablet-shaped electrolyte compact. LiN(R 1 SO 2 )(R 2 SO 2 ) (wherein R 1 and R 2 are identical or different from each other and each represent a fluorine atom, an alkyl group with 1 to 6 carbon atoms, or a fluoroalkyl group with 1 to 6 carbon atoms) (1).
