    Abstract All-solid-state lithium-sulfur batteries (ASSLSBs) are considered to be a promising solution for the next generation of energy storage systems due to their high theoretical energy density and improved safety. However, the practical application of ASSLSBs is hindered by several critical challenges, including the poor electrode/electrolyte interface, sluggish electrochemical kinetics of solid-solid conversion between S and Li

    Abstract All-solid-state lithium–sulfur batteries (ASSLSBs) are promising candidates for the development of next-generation batteries with high energy density and improved safety. Nevertheless, the sluggish reaction kinetics of the S and Li₂S cathode and the low active material content hinder the further development of ASSLSBs. Herein, a Co₃O₄@nitrogen-doped carbon (Co₃O₄@NC) nanocomposite is used as an electronically conductive additive to promote the conversion kinetics of S and Li₂S in the solid sulfur cathode. With a high sulfur content of 50 wt% and sulfur loading of 4 mg cm⁻², ASSLSBs with the S–Co₃O₄@NC–Li₇P₃S₁₁ (S–CoNC–LPS) composite cathode exhibit a high specific capacity of 1313 mA h g⁻¹ at 0.2 mA cm⁻², as well as a reversible capacity of 1167 mA h g⁻¹ after 100 charge/discharge cycles. Furthermore, the S–CoNC–LPS cathode also demonstrates a high areal capacity of 16.12 mA h cm⁻², corresponding to a reversible capacity of 1343 mA h g⁻¹, and good cycling stability even with an ultra-high sulfur loading of 12 mg cm⁻². Such a superior electrochemical performance can be attributed to the fact that Co₃O₄@NC lowers the reaction energy barrier and promotes the interconversion of S and Li₂S.

    Abstract KCNMA1 encodes the K+ potassium channel α-subunit that plays a significant role in the auditory system. Our previous studies indicated that KCNMA1 is associated with age-related hearing loss(AHL). However, the detailed mechanism of KCNMA1 involvement in auditory age-related degradation has not been fully clarified. Therefore, we explored the expression of KCNMA1 in the peripheral auditory of 2-month-old and 12-month-old mice by Western blotting and immunofluorescence. The results of animal experiments showed that KCNMA1 expression was decreased in 12-month-old mice compared with 2-month-old mice, whereas the ferroptosis level was increased. To verify the role of KCNMA1 in AHL, we downregulated KCNMA1 in HEI-OC1 cells by transfecting shRNA. After downregulation, the ferroptosis level was increased and the aging process was accelerated. Furthermore, the aging process was affected by the expression of ferroptosis. In conclusion, these results revealed that KCNMA1 is associated with the aging process in auditory hair cells by regulating ferroptosis, which deepens our understanding of age-related hearing loss.
