The article depicts structural, microstructural, and electrical behavior of Bi-0.5(Na0.8K0.2)(0.5)TiO3-BaNb2O6 (BNKT-BN) composite, synthesized by cost-effective solid-state reaction technique. The article demonstrates a detailed study of phase formation, impedance spectroscopy, ferroelectric, piezoelectric, and high-density energy storage behavior of investigated materials. The grain size distribution shows dense grain with an average grain size of composite within the range of 1.25 mu m-1.42 mu m. The investigation shows that with the addition of orthorhombic BN phase in tetragonal BNKT phase, the piezoelectric strain decreases from 0.0144% for 00BN to 0.0018% for 40BN. With the addition of 10% of BN phase, a sudden and significant drop in dielectric constant could be observed from -3485(00BN) to -1470, which also reduces the relaxor property of material. The 40BN with recoverable energy -136 mJ/cm(3) and -52% efficiency suggests the composition suitable for pulsed power application.
