Lithium-sulfur(Li-S) batteries have shown promises for the next-generation, high-energy electrochemical storage, yet are hindered by rapid performance decay due to the polysulfide shuttle in the cathode and safety concerns about potential thermal runaway. To address the above challenges, herein, we show a flame-retardant cathode binder that simultaneously improves the electrochemical stability and safety of batteries. The combination of soft and hard segments in the polymer framework of binders allows high flexibility and mechanical strength for adapting to the drastic volume change during the Li(de)intercalation of the S cathode. The binder contains a large number of polar groups, which show the high affinity to polysulfides so that they help to anchor active S species at the cathode. These polar groups also help to regulate and facilitate the Li-ion transport, promoting the kinetics of polysulfide conversion reaction. The binder contains abundant phosphine oxide groups, which, in the case of battery's thermal runaway, decompose and release PO· radicals to quench the combustion reactions and stop the fire. Consequently, Li-S batteries using the new cathode binder show the improved electrochemical performance, including a low-capacity decay of 0.046% per cycle for 800 cycles at 1 C and favorable rate capabilities of up to 3 C. This work offers new insights on the practical realization of high-energy rechargeable batteries with stable storage electrochemistry and high safety.

柔性热电发电技术日益被认为是为可穿戴电子设备供电的有效解决方案.然而,n型柔性薄膜的性能局限性限制了其更广泛的应用.本研究通过织构工程技术获得了高性能n型Ag2Se薄膜,在300 K时,功率因子高达2.14 mW m-1K-2.我们采用简单的蒸发镀膜技术,结合前驱体调控策略,制备了（201）取向的n型Ag2Se薄膜.实验和理论分析均表明,这种择优取向的Ag2Se薄膜具有高迁移率和高Seebeck系数.此外,纳米孔和随机面内取向结构的引入,显著散射了不同波长声子,从而使Ag2Se热导率进一步降低.最终,在363 K时,Ag2Se薄膜ZT值高达0.73.本研究不仅提出了一种调控Ag2Se薄膜晶体取向的策略方法,还为开发高性能热电薄膜材料创造了新的前景.
