Synthesis and Electrochemical Properties of Poly(acrylic acid)-co-Poly(glycerol methacrylate) Binders for Silicon-based Lithium Ion Battery Anodes. |
| 초록 |
Silicon (Si) has evolved as one of the most promising anode materials for high capacity lithium-ion batteries due to high theoretical capacity. However, a significant volume change of the Si during charge/discharge cycle causes pulverization and delamination, and thus becomes a major obstacle for commercialization. Among the several strategies to overcome the challenges of the Si anode, the development of properly designed polymeric binders is imperative for enabling stable cycling performance. In this study, we synthesized a series of poly(acrylic acid)-co-poly(glycidyl methacrylate) with various composition. Thermal, mechanical and adhesion properties of these binders were effectively manipulated by adjusting the composition of random copolymers. Most importantly, the optimum composition of copolymers that can maximize the cycling stability of Si anode was found, which exceeded that of Si anode prepared with conventional PAA binder. |
