Abstract
Sulfide-based solid-state batteries have emerged as a leading candidate for next-generation energy storage solutions, owing to their superior safety characteristics and high energy density potential. The composite cathode, as a critical component of sulfide-based solid-state batteries, requires precise microstructure optimization to significantly enhance overall battery performance. This paper compiles and synthesizes current research advancements, providing a comprehensive review of how sulfide electrolyte particle size distribution, active material loading ratios, and interface engineering critically influence composite cathode performance. The study also examines methods and mechanisms for developing high-loading cathodes to enhance cycling stability and rate capability, while summarizing associated challenges and potential strategies. Currently, this field faces notable challenges, including discrepancies between experimental and practical performance, reliance on static models, and difficulties in achieving low impedance with high-loading electrodes. To overcome these limitations and enable widespread application in electric vehicles and large-scale energy storage, we must establish multi-scale in-situ characterization platforms, develop multi-physics dynamic models, investigate novel interfacial materials, and optimize electrode manufacturing processes.
