ABSTRACT Conventional ionomer‐based membrane electrode assemblies (MEAs) in proton exchange membrane water electrolysis (PEMWE) suffer from severe catalyst agglomeration and high interfacial resistance, especially at ultralow iridium loadings. These issues, stemming from the insulating nature and uneven distribution of ionomers, significantly restrict electron and mass transpor…
ABSTRACT A durable solid electrolyte interphase (SEI) is essential to mitigating the mechanical fracture and interfacial instability of silicon anodes in view of strong electrochemical‐mechanical coupling. In this work, a uniform Li 2 O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI. By homogenizing the interfacial lithium…
