Fabrication and Structural Analysis of Barium Titanate-Doped Niobium Pentoxide Ceramics for Energy Storage System

Abstract

Dielectric materials are gaining attention for energy storage due to their high power density. However, their low energy density limits their applications. This paper explores dielectric materials with suitable permittivity and breakdown strength. It focuses on enhancing the energy storage capabilities of Barium Titanate-based ceramics by adding Niobium Oxide. The study investigates the effects of Nb2O5 addition on 0.98BT-0.02BMC ceramics. XRD analysis confirms a single perovskite phase for all compositions. The addition of Nb2O5 significantly improves dielectric and energy storage properties. The composition with x=4 exhibits a high dielectric constant (~2200), high energy density (1.40 J/cm³), high recoverable energy density (~1.10 J/cm³), and high efficiency (78.8%). This material shows promise for power pulse system. The Barium titanate can be used as a component in radiation detectors, such as ionization chambers and scintillation detectors. Its high density and atomic number contribute to its radiation-stopping ability
