The binder plays a crucial role in maintaining electrode structure and improving the cycling performance in LiS batteries, especially for high–energy–density batteries. Here, a natural biopolymer peach gum (PG) was developed as sulfur cathode binder for the first time. PG binder owns abundant carboxyls and hydroxyls, which can form strong interaction between LiO and further effectively constrain polysulfides from shuttling. Besides, strong adhesion force and superior mechanical behavior of PG help to keep the electrode integrity and good electrical contact. Therefore, PG@S electrode achieves an impressively high discharge areal capacity of 27.10 mAh cm⁻² with sulfur loading of 26.3 mg cm⁻².

粘合剂在维持电极结构和提高锂硫电池的循环性能方面起着至关重要的作用，特别是对于高能量密度电池。在这里，首次开发了一种天然生物聚合物桃胶 (PG) 作为硫阴极粘合剂。PG粘合剂具有丰富的羧基和羟基，可以在Li O之间形成强相互作用，进一步有效抑制多硫化物穿梭。此外，PG 的强粘附力和优异的机械性能有助于保持电极的完整性和良好的电接触。因此，PG@S 电极在硫负载量为 26.3 mg cm ^{-2 的情况下}实现了令人印象深刻的 27.10 mAh cm ^{-2 的}高放电面积容量。
