Design of Acrylic Copolymer Binders Toward High-Performance Silicon Anodes |
| 초록 |
Silicon has been acknowledged as a promising anode material for lithium-ion batteries due to its high theoretical capacity. However, a significant volume change of the silicon during charge/discharge deteriorates the electrode performance in the long run. A potential way to solve this problem is to develop polymer binders that can maintain the electrode morphology and conduction pathways for several cycles. Herein, we synthesized a series of random copolymer binders integrating acrylic acid and butyl carbamate groups that can provide hydrogen bonding. The effect of the adhesive and self-healing properties of the binder on the long-term cycling stability of Si anodes was systematically investigated by varying the molar ratios of each monomer. Interestingly, the cycling properties of Si anodes made from these binders showed a stronger dependency on the composition of the binder. This study sheds light on the design principles of polymer binders to extend the lifetime of Si anodes. |
