Abstract The development of new engineering disciplines underscores the imperative to cultivate engineering and scientific acumen,emphasizing the nuanced blend of comprehensiveness,practicality,and innovation.Simultaneously,the integration of green energy storage dielectric capacitors is posited as pivotal in realizing the fruition of clean energy utilization and catalyzing the trajectory of green economic development.Anchored in this overarching paradigm,experimental pedagogy seamlessly incorporates dielectric ceramic materials,with a focal emphasis on the environmentally benign (Bi,Na)TiO3(BNT) at its core,into thecomprehensive experiment of materials chemistry.This didactic module spans a gamut from unraveling the intricate operational tenets of dielectric capacitors to the meticulous orchestration of material composition and design,from the intricacies of preparation methodologies to the judicious deployment of performance testing paradigms.Meanwhile,it entails a probing analysis of microscopic structures and the delineation of hysteresis loops,culminating in a synthesis that encapsulates their collective impact on energy density and storage efficiency.By forging an organic nexus between foundational dielectric materials and the realm of scientific inquiry,this pedagogical approach imparts a profound comprehension of the underlying concepts and principles governing dielectric capacitors.This experiential voyage into the domain of clean energy storage devices not only augments students' theoretical acuity but also contributes substantively to the refinement of their proficiency in the domain of green chemistry.
