Improving energy storage density, piezoelectric, and energy harvesting performances of eco-friendly (Bi0.49−xBaxLa0.01Na0.40K0.10)TiO3 ceramics by composition design strategy
In this research, eco-friendly (Bi0.49−xBaxLa0.01Na0.40K0.10)TiO3 or BiBaxLNKT ceramics (where x = 0–0.15 mol fraction) were fabricated by solid-state mixed oxide technique, and their phase evolution, physical, microstructure, mechanical, dielectric, piezoelectric, ferroelectric, energy storage density, and energy harvesting properties have been systematically investigated. All ceramics exhibited a single perovskite structure. With increasing Ba content, a phase transition from mixed rhombohedral-tetragonal to be more tetragonal-rich phase was observed. The addition of Ba inhibited grain growth and resulted in densification, mechanical, and dielectric improvement. The maximum values of HV (6.01 GPa), HK (5.78 GPa), E (78 GPa), KIC (1.38 MPa.m1/2), εr (1604), and tan δ (0.0504) were observed for the x = 0.15 ceramic. The x = 0.15 ceramic also showed excellent piezoelectric performances (d33 = 248 pC/N, g33 = 17.46 × 10−3 Vm/N, and kp = 49%) and good off-resonance figure of merit (FoM) for energy harvesting (4.33 pm2/N). Moreover, after the introduction of Ba content, the ferroelectric long-range order is broken, which contributes to energy storage density improvement. Especially, the x = 0.05 ceramic achieved excellent recoverable energy storage density (Wrec = 1.31 J/cm3) and good energy storage efficiency (η = 96.18%) at 150 °C under driving electric fields (E) of 75 kV/cm. All results indicated that we can efficiently fabricate an environment-friendly (Bi0.49−xBaxLa0.01Na0.40K0.10)TiO3 system with good reliability for energy harvesting and high-temperature energy storage capacity applications.
期刊介绍：
While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including:
-insulating to metallic and fast ion conductivity
-piezo-, ferro-, and pyro-electricity
-electro- and nonlinear optical properties
-feromagnetism.
When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice.
The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
