摘要： The present invention relates to a solid electrolyte for an electrochemical device including a plastic crystal matrix electrolyte doped with an ionic salt, a composite constituted of networks formed by non cross-linked polymers and polymer cross-linked structures, and a manufacturing method for the solid electrolyte. Such an electrolyte has an ionic conductivity as good as a liquid electrolyte due to the use of plastic crystal, and has high mechanical strength - particularly, good flexibility - by applying networks formed by non cross-linked polymers and polymer cross-linked structures. Also, the manufacturing method of the electrolyte according to the present invention has the advantage of a simplified manufacturing process because a solvent is not essentially required. This electrolyte is excellent in both ionic conductivity and mechanical strength in terms of flexibility, and thus is suitable for cable-type batteries of which shapes can be easily modified.

摘要： Disclosed is an electrode whose surface includes an organic/inorganic composite porous coating layer comprising porous inorganic particles and a binder polymer, wherein the porous inorganic particles have pores having such a size that lithium ions (Li+) solvated in an electrolyte solvent can pass therethrough. A method for manufacturing the electrode and an electrochemical device using the electrode are also disclosed. The organic/inorganic composite porous coating layer formed on the electrode according to the present invention provides an additional pathway for lithium ion conduction due to a plurality of pore structures present in the porous inorganic particles. Thus, when the organic/inorganic composite porous coating layer is used instead of a conventional polymer-based separator in a battery, the battery can provide improved quality and an increased energy density per unit weight due to a reduced weight of the organic/inorganic composite porous coating layer.
