Synthesis of In-situ Crosslinked Aqueous Binder for Silicon Anodes in Lithium-Ion Batteries |
| 초록 |
Silicon (Si) has emerged as one of the most promising anode materials for high capacity lithium-ion batteries due to high theoretical capacity. However, an immense volume expansion of the Si anode for multiple cycles generate severe problems including pulverization and delamination of electrode. Such problems can be alleviated by employing rationally designed polymeric binders. For this purpose, we synthesized a series of poly(acrylic acid)-co-poly(glycerol methacrylate) with various compositions that can be processable using harmless solvent (i.e., water) and undergo in-situ crosslinking during drying process. By systematically investigating mechanical properties and adhesion of these binders, we found there is an optimum composition of copolymer binders that can surpass the cycling stability and the stability of the electrode over conventional poly(acrylic acid) binder. |
