Abstract:
An all-solid secondary battery, including: a first current collector; a pair of first active material layers disposed on opposite sides of the first current collector; a pair of solid electrolyte layers disposed on surfaces of the pair of first active material layers; a pair of second active material layers disposed on surfaces of the pair of solid electrolyte layers; and a pair of second current collectors disposed on surfaces of the pair of second active material layers, wherein a surface of one of the pair of second current collectors opposite to a surface of one of the pair of second active material layers does not comprise protrusions having a height of greater than about 8 micrometers.
