Nevertheless, their further development is hindered by challenges such as active iodine dissolution and polyiodide shuttle effect. Designing functional binders is considered as a cost-effective strategy to break through this dilemma. Herein, guar gum (GG), locust bean gum (LBG) and konjac gum (KGM) derived from natural plant are investigated as binders for iodine loading cathode of ZIBs. The spectral characteristic analysis and theoretical calculation results reveal that the binders' functional groups possess significant chemisorption and high adsorption energy toward iodine species, effectively suppressing iodine dissolution and polyiodide shuttling. For instance, the GG binder exhibits a lower Gibbs free energy during the iodine conversion reactions, indicating accelerated iodine redox kinetics. As demonstrated, the GG-based ZIBs remain impressive reversible capacity of 136 mAh g<sup>−1</sup> after 10000 cycles at 1 A g<sup>−1</sup> with high-capacity retention ratio of 80 %.

Equally important is ensuring the mechanical durability and long-term stability of these materials. Here, a fabrication strategy that combines ball-milling-assisted mono-dispersion and self-assembly techniques was reported to optimize the structure of aerogels. The SWCNTs are uniformly dispersed through electrostatic repulsion and steric hindrance during ball milling, while the self-assembly process modifies the internal hydrogen bonding of CNFs to prevent excessive densification. This dual approach facilitates the formation of a three-dimensional (3D) network via physical entanglement between SWCNTs and CNFs. Subsequent directional freeze-drying yields lightweight, elastic composite aerogels featuring a biomimetic spiderweb-like structure. The optimized aerogels exhibit outstanding electromagnetic wave (EMW) absorption properties, achieving a minimum reflection loss (RL<sub>min</sub>) of −38.9 dB, an effective absorption bandwidth (EAB) of 8.5 GHz, and a maximum radar cross-section (RCS) reduction of 34.44 dB·m². Additionally, these aerogels exhibit remarkable mechanical resilience, retaining up to 86.1 % stress over 50 compression cycles at extreme conditions (-20°C).
