Composite of Poly(ethylene glycol)-grafted Graphene Oxide : Novel Solid-state Lithium-ion Battery |
| 초록 |
All-solid-state lithium-ion battery is recent issue in energy industry for safety problem. Therefor, liquid electrolytes should be substituted to solid state. In this view, this research show that composites of branched-graft copolymer(BgCP) which are based on PEGMA and MA-POSS (Matrix) with Poly(ethylene glycol) grafted graphene oxide(PGO) (filler material) were applied to solid electrolytes. 0.2wt% of PGO composite electrolyte has much higher ionic conductivity than BgCP without PGO. Lewis acid-base interaction that includes much more lithium salt dissociation in the composite explain it. Electrochemical properties of composite electrolytes were evaluated and composite electrolytes with 0.2 wt% PGO showed noteworthy cycle performance compared to BgCP, because fllier implements formed the ion-conducting pathway and high ionic conductivity. |
