N2 - Relaxor ferroelectric capacitors receive extensive attention for the energy storage applications due to their slim polarization–electric field hysteresis loops. Typically, relaxor ferroelectrics can be designed through introducing multiple heterovalent cations in the ferroelectrics to break the long-range ferroelectric order and form polar nanoregion. Here, medium-entropy relaxor ferroelectric (Bi0.7Na0.67Li0.03)0.5Sr0.3TiO3 (BNLST) thin films with A-site chemical heterogeneity, synthesized by a chemical solution method, are studied as dielectric capacitors for the energy storage application. Mn doping is utilized to occupy cation vacancies to improve the electrical properties. High energy density (47 J cm−3), good efficiency (69%), and good frequency, temperature and fatigue stability are obtained simultaneously. These results show the potential applications of SBNLT relaxor ferroelectric thin film for dielectric energy storage. Graphical Abstract: [Figure not available: see fulltext.]
