Solid Lithium ion Battery with Poly(ethylene glycol)-grafted Graphene Oxide Composite Electrolyte |
| 초록 |
Conventional liquid electrolyte based lithium-ion battery systems have safety issues like leak, explosion etc. In order to solve the above problems, a solid lithium-ion battery system is essential. This study shows a composite electrolyte for this reason. Solid-state composite electrolytes consist of a PEGMA and MA-POSS copolymer matrix with poly (ethylene glycol) graft graphene oxide filler. The filler 0.2 wt% had significantly higher ionic conductivity of the matrix electrolyte than the matrix without the filler. The Lewis acid-base interactions that create dissociation of lithium salts contained in the matrix can explain the superiority. In addition, the composite electrolyte electrolyte showed a fairly stable cycle performance compared to the matrix without the filler because the ion-conductive paths were made by implementing the filler. |
