| Abstract | Despite the recent advancement in the in-practical active materials (e.g., silicon, sulfur) in the rechargeable lithium-ion energy storage systems, daunting challenges still remain for these high-capacity electrode material candidates to overcome the severe volume changes associated with the repeated lithiation/delithiation process. Herein, developing a room-temperature covalently cross-linked polyacrylamide (c-PAM) binder with high stretchability and abundant polar groups targeting the construction of high-performance Si and sulfur electrodes is focused on. The robust 3D c-PAM binder network enables not only significant enhancement of the strain resistance for working electrodes but also strong affinity to bonding with nano-Si surface as well as effective capture of the soluble Li2Sn intermediates, thereby giving rise to remarkably improved cycling performances in both types of electrodes. This rational design of such an effective and multifunctional binder offers a pathway toward advanced energy storage implementations. |
