<p>In recent years, remarkable multifunctional properties spanning semiconductor electronics to hydroelectric cells (HECs) in ferrite materials at nanoscale have significantly and successfully changed the way alternate forms of green energy and functional properties for its applications. In this study, Zn_1-xLi_xFe₂O₄ ferrite magnetic nanoparticles = 0.0 to&#xa0;0.4 have been synthesized using the sol–gel method to construct hydroelectric cells that produce green electricity with observation&#xa0;semiconductor and optical behavior. The TGA-DTA analyzer examined the Zinc ferrite thermal analysis and increased thermal stability with Li substitution. Increasing the Li + content in zinc ferrite, the crystallite sizes shrank from 44 to 18&#xa0;nm, as demonstrated by XRD and TEM measurements with <i>x</i> = 0.2 of Li substitution, which also resulted in the smallest crystallite size, the porosity of ferrite increased significantly. The presence of Li ion and the elements Fe, Zn, and O in the substituted nanoferrite were confirmed by decreases in weight ratio confirmed by EDX analysis. The energy band gap of Zn_1-xLi_xFe₂O₄ systematically increased from 2.33 to 2.48&#xa0;eV with increasing lithium content, which supports the semiconductor electronics properties. The optical absorption of Zn ferrite materials also increases with increase in Li concentration which support its uses in semiconductor electronics materials. Magnetic parameters and switching device factor also improve with increasing Li content from 2.56&#xa0;emu/g to 25.14&#xa0;emu/g value of saturation magnetisation that leads to varied applications. The maximum value of current found to be 10.9&#xa0;mA, which may support for its applications in hydroelectric cell as green energy. Nanopores produced by lithium-substituted zinc ferrite enhanced water dissociation and facilitated electricity production via surface cation-mediated redox reactions.</p>
