Organic/Inorganic Composite Electrolyte and Electrochemical Device Prepared Thereby |
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.
