제목 High Stability and High Conducting Epoxy-Based Solid Polymer Electrolyte Prepared via Crosslinked Polymerization
초록 Decades after the first it’s invention, rechargeable lithium ion batteries still aggressively and massively studied and developed. A classic major safety issues due to uncontrolled growth of lithium dendrites becoming a concern in the road of it’s development. Here, we prepare solid polymer electrolyte by cross-linked poly ( ethylene glycol ) diglycidyl ether (PEGDE) with N, N, - Dimethylbenzyamine (BDMA) into epoxy matrix. Combining epoxy matrix with weak-binding Li[TFSI] salt solvating in [BMIM] [TFSI] ionic liquid allowed SPEs generate high ion conductivity. The SPEs with higher ratio of PEGDE in the system reveal a better stretchability compare to SPEs with lower ratio of PEGDE. The enhancement of mechanical properties without neglecting ion conductivity performance is attributed to a perfect cross-linked polymerization and epoxy as framework support.
