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.

Edible bird’s nest (EBN)， abundant in sialic acid (SA) has been recognized as a natural substance beneficial to brain development and cognitive ability. In order to investigate active component of EBN， sialylated glycopeptides (SCP) were extracted from EBN by 60% ethanol after trypsin hydrolysis and its effects on central nervous system was evaluated in lipopolysaccharide (LPS)-induced neuroinflammation mice. EBN， SCP， and SA pretreatment and intervention reduced IL-1β， TNF-α， and IL-6 levels in hippocampus and cortex， meanwhile inhibited the activation of microglia， astrogliosis and neuron apoptosis， which were consistent with the learning and memory improvement and anti-depression effects in behavioral tests. The counts of leukocytes， neutrophils and monocytes， as well as IL-1β， TNF-α， and IL-6 levels in peripheral circulation were significantly reduced by SCP. Results of plasma metabolomics suggested SCP up-regulated energy metabolism， promoted the recovery of primary and secondary bile acid metabolism and indole metabolism， where microbiota may involve. 16S rDNA sequencing of colonic contents showed EBN， SCP and SA repaired dysbacteriosis in LPS-treated mice by significantly up-regulating the anti-inflammatory Muribaculaceae and inhibiting pro-inflammatory related Desulfovibrio and Candidatus＿Saccharimonas. In addition， both EBN and SCP could significantly enrich ***， while SA could specifically enrich Prevotellaceae＿UCG＿001. The gut-brain axis was preliminarily established， and SCP may have the potential to be a functional factor for neuroprotection applied in EBN industry.
