    Abstract Eco-friendly transparent dielectric ceramics with superior energy storage properties are highly desirable in various transparent energy-storage electronic devices, ranging from advanced transparent pulse capacitors to electro-optical multifunctional devices. However, the collaborative improvement of energy storage properties and optical transparency in KNN-based ceramics still remains challenging. To address this issue, multiple synergistic strategies are proposed, such as refining the grain size, introducing polar nanoregions, and inducing a high-symmetry phase structure. Accordingly, outstanding energy storage density (W

    Abstract Dielectric ceramic capacitors have been widely used in pulse-power technology because of their good performance of high power density and fast discharge speed. A series of lead-free relaxor ceramics (1-x)K₀.₅Na₀.₅NbO₃-xLa(Mn₀.₅Ni₀.₅)O₃ (KNN-xLMN) featuring with considerable charge–discharge behavior and energy storage properties were designed and prepared in this work. The grain size of ceramics decreases to 180 ± 20 nm, and the dispersion coefficient is > 1.6, both of which are beneficial to obtain slender P-E loops and improve the energy storage performance in K₀.₅Na₀.₅NbO₃ ceramics upon La(Mn₀.₅Ni₀.₅)O₃ doping. Consequently, acceptable dielectric properties (maximum permittivity εᵣ of 1693, Δε/ε₁₀₀ °C ≤ ± 15% from 33 °C to 309 °C, minimum dielectric loss tan δ of 0.028, 50 kHz) and a high recoverable energy storage density (Wᵣₑc ~ 1.65 J/cm³) accompanied by high energy storage efficiency (η ~ 76%) were obtained simultaneously in 0.97KNN-0.03LMN ceramics. Meanwhile, 0.97KNN-0.03LMN composition exhibited satisfactory charge–discharge performance (PD ~ 155 MW/cm³, t₀.₉ ~ 55 ns) and temperature stability (30 ~ 110 °C). This work not only proposes an efficient strategy to realize high energy storage and ultra-fast charge–discharge performance in lead-free KNN based ceramics, but also provide an candidate material for application of advanced pulsed power capacitors.
