“…Sodium perborate is non‐toxic, non‐carcinogenic, and biodegradable, making it a safer alternative to other oxidizing agents. Additionally, sodium perborate has a long shelf life and is easy to store and use making it an excellent choice for ASSSBs delivery 18 . In this perspective, we synthesized a cost‐effective and highly flexible polymer‐integrated solid electrolyte comprising PEO polymer as an ion‐conducting material, sodium perborate (Na 2 H 4 B 2 O 8 ) serves as a free Na + supplier, and NZSP as a dynamic ion conducting filler to resolve the aforementioned problems 19 .…”

The development of modern solid‐state batteries with high energy density has provided the reliable and durable solution needed for over‐the‐air network connectivity devices. In this study, a NASICON‐type Na3Zr2Si2PO12 (NZSP) ceramic filler was prepared using the sol‐gel method and then a polymer‐integrated solid electrolyte consisting of polyethylene oxide (PEO), NZSP, and sodium perborate (SPB) was prepared by Stokes' solution casting process. Through physico‐chemical and electrochemical characterization techniques, the morphology, electrochemical, and thermal properties of the prepared solid electrolyte sample were carefully studied. The PEO/NZSP/SPB electrolyte developed for all‐solid‐state sodium‐ion batteries (ASSSBs) exhibited a strong ionic conductivity, a large window for electrochemical stability, and was effective in controlling the growth of sodium dendrites. Furthermore, the polymer‐integrated solid electrolyte showed impressive rate capability, high discharge capacity (73.2 mAh g−1) at 0.1 mA cm−2, and good faradaic efficiency (98%) even after 100 cycles. These results reveal that the PEO/NZSP/SPB electrolyte is a potential and inevitable candidate for the evolution of high‐performance rechargeable ASSSBs.

Biomass feedstock ethylene glycol (EG) can be anodically oxidized to the high‐value glycolic acid (GA), which is widely considered as one critical raw material of biodegradable plastics. Developing low‐cost electrocatalyst to economically produce GA with high selectivity still meeting challenges. Herein, a non‐precious Co‐Ni bimetal catalysts are developed for controllable electrooxidizing EG to GA (EGOR). Through regulating the generation of key intermediate (CH2OH‐CO*) on the low‐cost catalyst surface, a successive electrooxidation from EG to GA has been achieved with high selective (96.3%) and conversion rate (>85%) at current density of 150 mA cm−2, which is on par with the reported precious metal catalysts. Through coupling with hydrogen evolution reaction (EGOR‐HER), 2.759 mmol H2 and 7.48 mmol of GA are generated at 80 mA cm−2, which also can save 27% energy comparing with a water splitting system. The synergistic effect between Co and Ni in the bimetallic catalyst has been exploited: high‐valent CoOOH sites catalyzed the generation of CH2OH‐CO* and reduce the energy barrier during GA formation; Whereas, Ni sites can effectively facilitate the formation of CoOOH and improve the adsorption of EG.
