Barium strontium energy storage battery

Strontium oxide nanostructures (SrO NSs) have garnered intensive research captivation among scientists owing to their higher specific energy, tunable material properties, and quick reversible reactions. However, low conductivity and poor cyclical stability hinder their use in energy storage devices, especially in supercapacitors.

Therefore, in this study, we report the synthesis of Barium-doped Strontium Oxide nanostructures (Ba-doped SrO NSs) using a composite hydroxide-mediated approach. Pure SrO NSs delivered the specific capacitance of 178 F/g at the current density of 1 A/g. The doping of Ba into SrO drastically improves the storage capacity.

This strategy involved utilizing Bi (Zn 2/3 Ta 1/3 )O 3 to induce polar nano-regions, contributing to an increase in Eb and a reduction in Pr, thereby enhancing the energy storage properties.

Its uniqueness is derived from the principle of electrostatic energy storage with ultrahigh power density and ultrafast charge and discharge rates, compared with other energy storage technologies such as batteries and supercapacitors.

Strontium oxide NSs FTIR spectrum the peak at 854 cm −1 is caused by the Sr–O bond [36, 37]. The formation of the Ba–O bond is represented by the absorption band at 698 cm −1 . The asymmetric and symmetric stretching vibrational frequencies of Sr–O are responsible for the absorption peaks at 1429 cm −1 [21, 31, 39].

It also increases electrical conductivity by providing additional charge carriers, thus reducing internal resistance and facilitating faster electron transport . The synergistic effects of Ba and Sr ions further optimize the material's electronic properties, contributing to improved electrochemical performance .
