摘要： The present disclosure provides a cable-type secondary battery, comprising: an inner electrode; and a sheet-form laminate of separation layer-outer electrode, spirally wound to surround the outer surface of the inner electrode, the laminate being formed by carrying out compression for the integration of a separation layer for preventing a short circuit, and an outer electrode.According to the present disclosure, the electrodes and the separation layer are compressed and integrated to minimize ununiform spaces between the separation layer and the outer electrode and reduce the thickness of a battery to be prepared, thereby decreasing resistance and improving ionic conductivity within the battery. Also, the separation layer coming into contact with the electrodes absorbs an electrolyte solution to induce the uniform supply of the electrolyte solution into the outer electrode active material layer, thereby enhancing the stability and performances of the cable-type secondary battery.

摘要： A solid electrolyte for an electrochemical device includes a composite of a plastic crystal matrix electrolyte doped with an ionic salt and a crosslinked polymer structure having a linear polymer as a side chain chemically bonded thereto. The linear polymer has a weight average molecular weight of 100 to 5,000 and one functional group. The electrolyte has high ionic conductivity comparable to that of a liquid electrolyte due to the use of the plastic crystal, and high mechanical strength comparable to that of a solid electrolyte due to the introduction of the crosslinked polymer structure. A method for preparing the solid electrolyte does not essentially require the use of a solvent, eliminating the need for drying. The electrolyte is suitable for use in a cable-type battery whose shape is easy to change due to its high ionic conductivity and high mechanical strength comparable to that of a solid electrolyte.
