The present invention relates to a positive electrode comprising a positive electrode active material, a first conductive material, a first binder and a first gel polymer electrolyte; A negative electrode comprising a negative electrode active material, a second conductive material, a second binder and a second gel polymer electrolyte; A solid electrolyte layer positioned between the anode and the cathode; And a third gel polymer electrolyte formed on both sides of the solid electrolyte layer. The pre-solid lithium secondary battery of the present invention includes a gel polymer electrolyte on both surfaces of a cathode, a cathode, and a solid electrolyte layer, thereby exhibiting excellent discharge capacity and cycle characteristics. In addition, the pre-solid lithium lithium secondary battery of the present invention can be manufactured in a non-sintered manner using a gel polymer electrolyte to produce a pre-solid lithium secondary battery, thereby reducing manufacturing cost and ion conductivity. |
