Electrical Capacity Study of Charge Accumulators’ Adsorption on ZrO_۲-۳ mol.%Y_۲O_۳ Nanosystems

This scientific article discusses the possibility of using zirconium dioxide nanopowders stabilized with ۳ mol.% yttrium oxide (ZrO₂-۳ mol.% Y₂O₃) as a promising material for solid-state electric charge storing devices. Due to their high surface area and unique dielectric properties, these nanopowders offer advantages over conventional bulk materials in terms of charge storage efficiency. Examples of comparing the electrical capacitances of samples saturated at a relative humidity of ۳۵% and close to ۱۰۰% are provided. It is revealed that increasing atmospheric humidity leads to a significant increase in the capacitance of nanostructured samples. This behavior is attributed to enhanced ionic mobility and polarization effects induced by water molecules adsorbed on the surface. This confirms the key role of adsorbed moisture in the processes of charge accumulation and retention on the nanoparticle surface. Such moisture-dependent performance suggests potential for environmental sensing applications. The presented experimental results show that this material can be used to develop nanoca-pacitors for microsystem technologies and capacitive humidity sensors of a new generation. Overall, the findings contribute to the growing field of nano-enabled energy storage and sensor design.
