Abstract
The present invention relates to a cyclic siloxane-based compound and a solid polymer electrolyte composition containing the same as a crosslinking agent. The cyclic siloxane-based compound having a novel structure in which polyalkylene oxide acrylate groups are introduced into a cyclic siloxane compound and a solid polymer electrolyte composition containing the cyclic siloxane-based compound as a crosslinking agent along with other electrolyte components such as a plasticizer, lithium salt and a curing initiator. Since the solid polymer electrolyte composition of the present invention improves ion conductivity and electrochemical stability at room temperature, it can be useful as polymer electrolyte for electrolyte films, small-sized to high-capacity lithium-polymer secondary batteries, etc. Also, physical properties of the polymer electrolyte can be controlled easily by controlling the length of the polyalkylene oxide group in the cyclic siloxane-based crosslinking agent.
